English
BOPET Thermal film for packing is a type of packaging substrate made from biaxially oriented polyethylene terephthalate (BOPET) that is coated with a thin layer of metal.This coating is typically made from aluminum or other metals, and it serves several purposes. First, it provides a barrier against moisture, oxygen, and other gases that can degrade the quality or freshness of the product inside.Second, it creates a shiny, reflective surface that can help products stand out on the shelf.

Heat Sealability
BOPET thermal film for packing is designed to be easily heat sealed. With its optimized surface properties, this film can be easily sealed on both sides while maintaining a strong bond with the package contents.
Superior Transparency
BOPET thermal film offers excellent clarity, allowing the product to be displayed clearly even when it is inside the packaging. This feature of the film helps to increase the aesthetic appeal of your product, making it more eye-catching on the shelf.
Cost-effective
BOPET thermal film is cost-effective compared to other packaging solutions. It provides an excellent alternative for businesses looking to cut costs and improve the quality of their packaging.
