PP lamination is a protective film mainly made of Polypropylene (PP) film, which is adhered to the surface of printed matter or packaging through heat pressing or composite processes.
Material composition and properties：
The core material of PP lamination is polypropylene resin, which is made into transparent or semi-transparent films through processes such as extrusion, stretching or casting
. Its main performances include:
High strength and durability: It has excellent tensile and impact resistance, making it suitable for packaging that requires wear resistance and folding endurance.
High-temperature resistance: Ordinary PP film can be stably used at 100℃ to 130℃. Some thickened models can withstand microwave heating and are suitable for food packaging
Transparency and luster: The surface is smooth and transparent, which can enhance the visual effect and color vividness of printed matter
Chemical stability: It has good corrosion resistance to acids, alkalis, salts and other chemicals
Heat sealing property: It can be firmly sealed through heat sealing technology, facilitating packaging and processing
Heat sealing property: It can be firmly sealed through heat sealing technology, facilitating packaging and processing
