What Label Material Is Best for Hot Environments?

When your product has to survive heat, the right material and adhesives will keep your packaging intact instead of bubbling, peeling, or sliding off. Here’s what actually works when the heat gets turned up.

BOPP (Biaxillary Oriented Polypropylene) Labels

Why people consider it: BOPP is the budget-friendly option for consumer goods. It’s clear, glossy, and affordable, but not built for sustained heat.

Best applications:

• Low- to medium-heat packaging 
• Products that don’t go through pasteurization or retort

Pros:

• Affordable and widely available
• Crisp print quality with multiple finish options

Cons:

• Softens under true hot-fill or pasteurization
• Not reliable for sustained high heat
• Can lose adhesion or distort, impacting product legibility and durability in transit or storage

We typically recommend BOPP only for products that don’t exceed mild warmth. If you do hot fill or require pasteurization, a more cost effective option is to label after those are completed. 

MDO Labels

Why people consider it: MDO is flexible and can stretch around odd shapes.

Best applications:

• Moderate-heat environments
• Containers with curved or irregular surfaces

Pros:

• Great flexibility and wraps easily around curved or irregular containers
• Works on unique packaging shapes

Cons:

• Softens under true hot-fill or pasteurization
• Not reliable for sustained high heat
• Can lose adhesion or distort, impacting product legibility and durability in transit or storage

Depending on the package, we may recommend vinyl for curved or textured surfaces, but if heat resistance is required, we’ll likely shift to PET or polyimide.
