How to Prevent Labels from Cracking or Curling in Cold Storage

Cold storage is tough on labels. Between condensation, big temperature swings, and freezing temps, it’s easy for labels to curl, crack, or peel off if you don’t plan ahead. With the right choices in materials, adhesives, and finishes, your labels can hold up through the cold chain.

Cracking is usually a material problem. Papers tend to become brittle in the cold. Curling is usually an adhesive or application problem, such as the wrong temperature rating, moisture at application, or not enough bonding pressure.

Most of the time, the recipe for success is simple: pair a cold-rated adhesive with a moisture-resistant film and a protective finish.

Choosing the Right Label Materials for Cold Storage

The material your label is printed on sets the foundation for durability, and can be the difference between a label that cracks or curls and one that holds up.

For cold storage, some of the best material choices include:

BOPP (biaxially oriented polypropylene): A flexible plastic film that resists water and tearing. Think of it as the go-to for frozen dinners, ice cream, and beverages that end up in ice buckets.
PET Films: A tougher, slightly stiffer plastic that offers extra durability and holds its shape well. Often used in pharmaceuticals or premium products that require added toughness.

While those materials are good options, be more careful of these materials that could give you problems:

Coated paper: Works for dry, refrigerated cartons, but in humid coolers or freezers it’s prone to curling or smearing. Specialty freezer papers exist, but they’re usually best for secondary packaging.
Textured/uncoated papers: They may look great on a wine bottle at room temp, but in a cooler or freezer they soak up water and start peeling.

Rule of Thumb: If your product may sweat, freeze, or sit in an ice bath, films (BOPP or PET) are usually the safer choice. Paper is generally limited to dry, refrigerated environments.

Using the Right Adhesives

Adhesives are one of the most critical factors in whether your label will hold. Even the best label material or finish can fail if the adhesive isn’t matched to your application and storage environment.

First, you should know two different measures of temperature:

Application Temperature = the temperature when you apply the label.
Example: applying to a frosty beer can at 35 °F.
Service Temperature = the temperature where the product stays.
Example: a frozen entrée stored at –10 °F.

Knowing that for your specific product(s), you can then identify an adhesive that is compatible with your product’s environment:

All-Temperature Acrylics: Apply at ~20–40 °F, service down to –40 °F. Best for refrigerated foods, dairy, and beverages.
Freezer-Grade Acrylics / Hot-Melts: Apply as low as –20 °F, service down to –60 °F. These are designed for aggressive tack on frosty or wet cartons.

Note: These ranges are based on supplier specifications (Avery Dennison, UPM Raflatac, etc.), but it’s always important to double-check that the numbers line up with how you actually run your line.

Rules of Thumb: Refrigerated → all-temp. Frozen → freezer-grade.

Surface preparation for bottles

Prepare the Surface Properly

Even the right material and adhesive can fail if the application surface isn’t ready.

Clean & Dry Surfaces: Moisture, frost, or dust prevent adhesives from bonding.
Wet Applies: For cold-fill beverages or condensation-prone lines, use a wet-apply freezer adhesive designed for these conditions.

Protecting Your Labels

Finishes shield against water, abrasion, and smudging. Here are some options:

Gloss or matte laminate: Provides strong moisture protection to keep labels from whitening or peeling in cold storage. Matte laminates can still offer comparable durability while delivering a more soft or premium look.
Gloss or satin varnish: Offers a more subtle finish but generally provides less moisture protection than laminates. Best for applications on paper substrates where moisture exposure is minimal or texture and embellishment effects take priority.

Recommendation: For cold storage, pair a film base material (like BOPP) with a laminate for the most reliable protection.

Cold storage in grocery store

What Else to Consider?

A few additional factors will be helpful to share with your label printing partner so that your labels perform well throughout the cold chain:

Container Material: Adhesives interact differently with glass, PET, corrugated, or HDPE. For example, glass often benefits from freezer-grade acrylics for stronger bonding.
Temperature Cycling: Will your product move freezer → retail shelf → consumer fridge? Each swing stresses both adhesive and base material.
Moisture Exposure: Is your product sitting dry in a carton, or submerged in an ice bucket?
Regulatory Needs: Food and pharma labels must remain legible, include FDA-required information, and be barcode scannable for retail. Peeling or smudging can create compliance issues.

Quick Checklist for Avoiding Failures

Choose BOPP or PET films for refrigerated or frozen storage.
Match adhesive to your application & service temps.
Use wet-apply adhesives for cold-fill or condensation-prone lines.
Add a laminate for moisture-heavy environments.
Apply to clean, dry containers whenever possible.
Test labels through your actual cold chain, for example by running freezer-to-fridge-to-room temp cycles, and check for peeling, whitening, or smudging before scaling.

How to Prevent Labels from Melting or Warping in Hot-Filled Products

If you’ve ever had labels warp, peel, or slide right off bottles or jars after hot filling, you know how frustrating and costly that can be. We’ve seen it all, and we know what works (and what doesn’t). It’s always best to apply labels on a clean, dry, and room temperature container. But, sometimes it is necessary to hot fill.

Here’s what you need to know to keep your labels intact in hot-fill conditions.

Quick Checklist to Avoid Hot-Fill Label Failures:

Select heat-resistant label materials (like BOPP or PET)
Use adhesives specifically rated for high temperatures
Make sure containers are clean, dry, and prepped right
Choose label finishes that add durability (laminates, varnishes)
Test label performance in real-world conditions before scaling up

Pick the Right Label Material

The first thing to get right is your label material. Not all of them handle heat the same way. We recommend:

BOPP (Biaxially Oriented Polypropylene): Durable, heat-tolerant, and reliable.
PET (Polyester): Excellent heat resistance and dimensional stability.
MDO: Similar to BOPP in terms of durability, heat tolerance, and reliability, MDO may be the better option depending on the container due to its flexibility.

Standard paper labels? Paper labels are possible for hot-fill products but be mindful of the type of adhesive used.

Not sure which material makes sense for your product? Contact us and we’ll walk you through it.

Choose Heat-Resistant Adhesives

Your adhesive is just as important as your material (if not more). Without the right one, even the best label will fail.

Most high-temp adhesives are rated for around 180–200°F, but results can vary depending on your container and fill speed. Always check the adhesive spec sheet and make sure it’s tested for your exact application.

Add Label Finishing for Extra Protection

Finishes help your label survive the journey from fill line to store shelf. They protect against scuffs, moisture, and the occasional warehouse disaster. Here’s what we like:

Clear polypropylene or PET lamination: Great for moisture and abrasion resistance. Check out our lamination options.
UV Varnishes: Good for extra durability without changing the feel too much.

Some finishes can change the look or feel a bit, so test them out before you commit.

Prep Your Containers the Right Way

Labels don’t stand a chance on a wet or dirty surface. And if you’re labeling plastics like polypropylene or HDPE, you’re starting with a tough surface to bond to. Here’s what helps:

Dry the containers completely. Use air knives or drying tunnels.
Wipe away oils, dust, or residue.

Prep won’t fix everything, but it goes a long way toward keeping your labels where they belong.

Apply Labels Under the Right Conditions

When it comes to applying labels after a hot fill, timing and pressure make all the difference:

Temperature: Wait until containers cool to below 90°F before labeling.
Pressure: Use consistent pressure so the label fully bonds.
Dwell Time: Let the adhesive cure for at least 24–72 hours before handling or shipping. That gives it time to fully settle in, especially in humid or changing environments.

Running at scale? Run a small test batch first and check with your applicator manufacturer for pressure settings.

Validate and Test Before You Go All In

Even with the right setup, things can go sideways. That’s why testing is key. We suggest:

Run a short trial batch.
Mimic your exact fill and cooling process.
Check your labels right away, then again after 24 and 72 hours.

Look for curling, peeling, bubbling, or anything that could get worse later. A little testing up front can save you a lot of headaches later.

Quick Summary

If you want labels that stay put after hot filling, you need the right combo of materials, adhesive, prep, and finishing.

How To Prevent Labels from Peeling in the Refrigerator

No brand wants a great looking product only for the label to peel off in the customers’ fridge. Fortunately, with the right materials, adhesives, and preparation, you can keep your product’s labels firmly in place even in chilled environments.

Why Labels Peel in Refrigerated Conditions

Let’s start with the usual suspects behind label peeling in the cold. The culprits usually include:

Moisture and condensation
Improper adhesive or material selection
Poor surface preparation
Temperature fluctuations

Below we take a closer look at how each of these factors can cause problems, and how to make the right decisions to avoid issues down the line.

Choose the Right Label Material

Your label material makes a huge difference in refrigeration performance. Consider these materials:

Welded Paper Stock: Combines the tactile appeal of paper with a BOPP film core for moisture protection and excellent opacity. These labels resist degrading in ice bucket immersion and condensation while still allowing for embellishments like embossing, foil, or die cuts. Welded paper stock is ideal when you want a premium look that also performs under chilled conditions.
BOPP (Biaxially Oriented Polypropylene) and MDO (Polypropylene): Durable, moisture-resistant, and ideal for beverages, dairy, sauces and more.
Polyester (PET): Strong and moisture-resistant, commonly used for refrigerated medicines and supplements, specialty foods, and more.
Vinyl (PVC): Flexible and sticks better to curved surfaces like squeeze bottles (MDO works great for curved surfaces and squeeze bottles as well).

For most plastic or glass containers, we recommend using water-resistant films or welded paper stocks, which give you the durability to withstand chilled environments and moisture.

Select Adhesives That Stick

Most standard adhesives struggle in cold, damp environments where moisture and condensation interfere with adhesion. Instead, consider freezer-grade options:

Acrylic Adhesives: Excellent moisture resistance and long-term adhesion.
Freezer-Grade: Immediate strong adhesion at lower temperatures.

Prep Your Surfaces Properly

We’ve seen it plenty of times: labels that just won’t stick because the container wasn’t clean or dry. Here’s how to avoid that:

Always clean and dry your containers before applying labels.
Apply labels at room temperature whenever possible. Cold surfaces mean weaker initial bonds.
Allow enough dwell time (ideally 24 hours) before refrigerating to make sure your adhesive fully sets.

Add Extra Protection with Finishing

A protective layer goes a long way toward preventing peeling, smudging, or abrasion:

Lamination: Adds a water-resistant barrier and increases durability.
UV Coating: Protects against moisture and keeps labels looking vibrant.

While finishes like lamination and UV coating can add a small cost, they often prevent smudging or damage that could otherwise make your product look worn before it even reaches the shelf.

Test Before You Scale

It can be important to test your labels in real-world refrigerated conditions, especially before committing to a large full run. This helps you feel confident that they’ll perform the way you need them to. Here’s how (don’t worry, we can help with this):

Conduct freeze-thaw cycles and check for peeling.
Simulate actual handling and transport conditions.
Evaluate adhesion after at least 24 hours in your target refrigerated environment.

Quick Checklist to Avoid Label Peeling

Choose the right material. We recommend EverOpaque, BOPP, PET, vinyl, or wet-strength paper.
Select acrylic or freezer grade adhesives that will perform at the correct temperature.
Clean and dry all containers before application.
Apply labels at room temperature.
Allow 24-hour dwell time before refrigerating.
Consider protective finishing like lamination or UV coating.
Always test labels thoroughly in real conditions.

Prevent Your Label from Peeling in Refrigerated Environments

Label peeling in cold storage doesn’t have to be a problem. With the right materials, adhesives, preparation, and testing, your labels can withstand even the chilliest conditions. Not sure where to start? Contact us and we’ll help you select labels that stick, no matter the temperature.

Shrink Sleeves vs. Pressure-Sensitive Labels: Which Is Right for Your Product?

We’ve worked with thousands of brands, many of which ask this exact question: shrink sleeves or pressure-sensitive labels? Both options can help your product stand out, but the right choice depends on your product, container shape, design goals, and budget.

We put together this guide to break down market trends, key differences, compliance considerations, eco-friendly options, and questions to ask as you decide which path option fits your product best.

Shrink Sleeves vs. Pressure-Sensitive Labels

Consumer & Market Trends

Shrink Sleeve Label Trends

Shrink sleeves are a popular choice because they offer 360-degree, full-container designs, they can fit just about any container and offer built-in tamper-evident protection, they are resistant to moisture, and offer a number of eco-friendly material options.

Their popularity is especially strong in categories like beverages, nutraceuticals, and personal care. Consumers are drawn to shrink sleeves because they give products a “premium” look and often feel more modern.

For many brands, the choice comes down to aesthetics: if you want a full-covered can or bottle, shrink sleeves are typically the better option.

Pressure-Sensitive Label Trends

Pressure-sensitive labels continue to be a dominant choice across industries like beverage, food, health, and more due to their adaptability, affordability, and print versatility.

Consumers still want clear, legible, high-quality labels, and digital label printers can provide fast turnaround and a wide range of customization. Pressure-sensitive labels come in a wide range of materials and even offer some eco-friendly options for brands focused on sustainability. Brands can customize their label to appeal to changing consumer interests by using stocks with texture, foils, and finishes from matte to glossy, metallics, die cutting, and embossing.

Another advantage: pressure-sensitive labels can use specialty materials like glitter or holographic film. To achieve a similar effect with shrink sleeves, you’d need to use foil stamping.

Key Differences Between Shrink Sleeves and Pressure-Sensitive Labels

Here’s a side-by-side look at how shrink sleeves and pressure-sensitive labels compare:

Feature	Shrink Sleeves	Pressure-Sensitive Labels
Coverage	Full 360-degree design covering the entire container	Typically cover the front/back or wrap partially around the container
Container Compatibility	Great for unique or contoured shapes; works best on smooth container surfaces; works with glass, PET, HDPE, aluminum, and other rigid materials	Works best with flat or slightly curved surfaces; works across glass, plastic, cardboard, and metal
Embellishment Options	Gloss, satin, or soft touch varnish; screen printing; spot UV (most finishing techniques available, though effects like glitter/holographic require foil stamping)	Lamination, UV varnish, foil, embossing, spot UV, textured varnish, screen printing (plus unique stocks like glitter or holographic films)
Application Process	Requires heat application (special equipment)	Applied with pressure, simpler equipment or can be applied by hand.
Compliance Features	Easily integrate tamper-evident seals	Can incorporate tamper-evident closures, but often require additional materials
Sustainability	Typically harder to recycle, though recyclable shrink films are emerging	Eco-friendly material options (e.g., recycled, FSC-certified, compostable)
Cost Considerations	Higher application and material costs, but high impact (not cost-effective until you’re producing in the thousands; at that point, specialized application equipment like heat tunnels is usually required)	Cost-effective for small to large runs, flexible pricing options (a better fit for smaller operations running fewer than 1,000 labels, since application is simpler and doesn’t require heat equipment)

How Labels Handle Environmental Factors

Labels need to survive manufacturing, storage, shipping, and real-world use. Here’s a comparison of how shrink sleeves and pressure-sensitive labels compare in real-world conditions:

Product with shrink sleeve label

Shrink Sleeves

Perform Well: High-moisture environments (think refrigerated beverages, frozen foods, or bath products) where sleeves protect graphics under a film layer. They’re also scuff-resistant, making them ideal for shipping and handling.
Use Caution: Extreme heat in storage or transit can distort sleeves. Textured or flexible containers may not shrink evenly, leading to distortion.

Beer cans with labels

Pressure-Sensitive Labels

Perform Well: Dry, stable environments like pantry goods, shelf-stable beverages, or cosmetics. With the right materials and adhesives, they are more resistant to refrigeration, moisture, and even some oils.
Use Caution: Long-term exposure to condensation, freezing, or rough handling can cause edges to peel, wrinkle, or scuff.

Eco-Friendly Options

Both shrink sleeves and pressure-sensitive labels have eco-friendly options, with shrink sleeves increasingly adopting recyclable films and thinner materials, while pressure-sensitive labels currently offer a broader range of recyclable and sustainable choices.

Shrink Sleeves: Traditional shrink films are more difficult to recycle, but options like perforated sleeves that separate from containers are becoming more common.
Pressure-Sensitive Labels: These labels offer a wider variety of eco-friendly substrates, including recycled content, FSC-certified papers, and compostable materials. For brands prioritizing sustainability, pressure-sensitive labels often provide more options today.

Compliance and Safety

Certain products require features like tamper-evident seals or extra label space for regulatory information. Here’s how shrink sleeves and pressure-sensitive labels stack up:

Shrink Sleeves can double as both a label and a tamper-evident seal by extending over the cap or lid, which is a strong advantage for food, beverage, and pharmaceutical products.
Pressure-Sensitive Labels can also accommodate compliance features, but tamper-evident solutions may require additional materials, such as neck bands or secondary seals.

[Checklist] Questions to Ask Before Choosing

Does my container have a unique or contoured shape that might be better served by shrink sleeves?
Am I trying to maximize visual impact with full 360-degree coverage, or do I prefer a classic look with front/back panels or a label that partially wraps around the container?
What’s the aesthetic I want: bold, full-coverage graphics or a more traditional panel look?
What compliance requirements (tamper-evident seals, ingredient space) do I need to meet?
Is sustainability a major priority for my brand, and which material aligns better with that goal?
How many labels am I applying: fewer than 1,000, or in the thousands?
Do I have (or need to invest in) the right equipment, like a heat tunnel, to apply shrink sleeves?
What’s my budget for both label printing and application equipment?
How important is speed and ease of application in my production process?
What kind of environment will my product/label be exposed to?

Ready to Decide?

Shrink sleeves can be a better choice when you want bold, high-impact designs or need tamper-evident features built in. Pressure-sensitive labels remain the most versatile option, with more sustainable material choices and cost-effective production for a wide range of products.

The right fit comes down to your product, your container, and your brand. Need help deciding? Contact us and we’ll walk you through the options.

Can Paper Labels Be Used on Cans?

Thinking about using a paper label on your cans? It’s possible and it can look great if you get the materials and application just right. Here’s what to consider before you commit.

Checklist Before Choosing Paper Labels

1. Can Surface & Shape Compatibility

Standard aluminum cans give you a smooth surface to work with, but things like condensation and spillage, it can still mess with label adhesion. Paper labels work well on gently curved cylinders. They’re not a great fit for tapered or sharply contoured shapes (see below).

2. Environmental Conditions

Paper without a protective finish struggles with moisture, cold, and friction.

Cold environments: Paper labels can start to struggle if your cans sit in cold storage (think under 40°F) for more than a quick chill.
Abrasion and handling: Labels can scuff, fade, or peel if not protected. A UV varnish or laminate makes a difference. (check out our guide to label durability for more info on this)

Paper needs a finish to survive distribution and refrigeration. That’s especially true for cans chilled before shelf display or used in ice buckets.

3. Finishing Options & Design Considerations

Paper gives you a lot of flexibility with look and texture, but without protection it won’t last in tough conditions.

You can improve both performance and presentation with:

UV varnish or gloss/matte lamination – a clear coating or protective film that shields your label from moisture, friction, and fading. See our lamination options.
Embossing or foil stamping – great options for coated or metalized paper

These finishes help keep moisture out, especially around the label edges where peeling or bubbling usually begins. They also help preserve that premium, hand-crafted texture that makes paper stand out.

4. Adhesive & Application Process

Not all adhesives behave the same on metal, especially in cold or wet conditions.

Acrylic-based adhesives generally hold up better in cold or humid environments.

It’s worth checking with your label provider to make sure the adhesive has enough tack time for your fill speed and conditions. If your line runs above 300 containers per minute or you’re applying labels to chilled cans, slower-tack adhesives can lead to labels shifting or lifting, especially if there’s condensation.

5. Regulatory & Food‑Safety Compliance

Any adhesive or ink needs to meet FDA indirect food contact standards. That means no harmful transfer if the label touches the product (like a wet can top contacting your mouth).

Your label also has to include everything required by the FDA or TTB: nutrition facts, identity statements, traceability codes, and allergen info, and it all has to hold up in real conditions without smearing or wearing off.

If you’re not sure how your label will hold up, ask about durability testing. There are standard ways to check for things like peel strength and moisture resistance.

6. Recyclability & Sustainability Trade‑Offs

Paper labels usually add about 1 to 1.5 grams to a standard aluminum can (around 8–10% of its total weight, depending on the material and finish). That can cause issues in some recycling systems that use weight to sort materials. For example, in parts of Canada, labels that add more than 1% to the can’s weight may keep it out of curbside recycling.

Removable adhesives can make things easier at the MRF (Materials Recovery Facility), but they don’t hold up as well in cold or wet environments and tend to tear more easily.

Quick Checklist: Can Paper Labels Work for You?

If you check all of these boxes, paper might be a viable option for your cans:

Label will be applied to a clean, oil-free metal surface
Can shape is gently curved—not heavily tapered
Environment does not include heavy refrigeration, condensation, or handling
You use coated paper with laminate or UV varnish for moisture and abrasion resistance
Adhesive is chosen for specific storage conditions
All inks and adhesives meet food-safety and traceability specs
You’ve considered recyclability and weight impact

Practical Use Cases Where Paper Works Well

You can expect paper labels to perform reliably when these apply:

Medium‑volume products stored in dry or ambient environments (like dry-mix cans)
Cans sold at room temperature or filled/packed with minimal chilling
Brands that want a natural or craft look but still need a label that sticks

In these situations, coated paper with a durable finish gives you a lower-cost solution that doesn’t sacrifice style or performance.

paper labels

When You Should Consider Film Instead

While paper can work on cans with all the right considerations, we typically recommend film labels, especially in high-moisture or cold-fill environments. Think about film labels in the following situations:

Your cans go into ice, freezers, or chilled displays for long periods
You handle large volumes that require consistent, high-speed application
Your can shapes include steep tapers or ridges where adhesion is tricky
Your product must be “infinitely recyclable” without residue

Film labels like BOPP, PET, or shrink sleeves are better suited for moisture, abrasion, and temperature extremes.

Bottom Line

Paper labels can work on cans, but only if you pair them with the right coatings, adhesives, and application process. When the conditions get tough (cold, wet, abrasion), film often becomes a safer bet.
