Characteristics
Excellent adhesion of aluminum layer,greatly increasing the laminated strength with other materials;
Replacement of VMPET or aluminumfoil,itis used in the middle layer of the three-layer structure to become mono material structure.
Excellent oxygen and moisture barrier properties,extendingthe shelf life;
Application
- It can prevent visiblelightand ultraviolet radiation and extend the shelf life.
- Replacement of aluminum foiland VMPET,withbetter processing performance and environmentally friendly recycling treatment;
- Packaging of dried fruits,tea,coffee,chocolate,
dehydrated food,flavors and fragrances,medicines,etc.;
