Polyimide, PET, polyester, and specialty paper for thermal environments.
In industrial label production, heat-resistant labels are often an underestimated technical factor—until problems arise on the production line or out in the market. Yet it is precisely these details that determine whether labels hold up in real-world environments, whether they are compatible with automatic labeling machines, and whether they can protect product information throughout the entire product lifecycle.
Hirich approaches heat-resistant labels from real-world experience with hundreds of businesses across the cosmetics, food, pharmaceutical, beverage, and logistics industries. We don’t just advise on materials—we analyze the entire journey of the label: from raw material warehouse, through the printing and die-cutting machines, to the labeling line, and finally to the consumer’s usage environment.
Questions to answer before choosing heat-resistant materials.
Each business has its own unique challenge: some need labels that withstand bottle washing cycles in the beverage industry, some need labels that won’t peel off in -25°C freezers, and others need labels that resist solvents in the chemical sector. There is no one-size-fits-all label solution. Hirich works directly with our customers’ technical teams to pinpoint the exact requirements and recommend the most optimal label structure.
How to Handle Bubbling Defects on Labels
One of the most common and serious technical defects with labels is bubbling—the appearance of air pockets or peeling beneath the label surface after application, particularly on refrigerated or frozen products, or in high-humidity environments. This is not merely an aesthetic issue; it also compromises barcode scanability, information durability, and consumer trust.
Hirich tackles bubbling from three angles: selecting the right adhesive for the surface and usage environment, optimizing application pressure and temperature during label application, and verifying adhesion on real samples through Hirich’s Sample Approval Process before mass production. As a result, businesses avoid facing complaints from customers or distribution partners over labels peeling off once products hit the shelves.
Comprehensive solutions from Hirich
Hirich is committed to walking with you every step of the way—from initial technical consultation and sample approval on real materials, to production under strict QC and post-delivery support. We understand that a single faulty label roll doesn’t just waste materials; it can bring your entire packaging line to a halt. That’s why every batch of labels leaving the Hirich facility has been meticulously inspected to ensure smooth, stable operation from the very first run.
