18 μm metallized BOPP film offering oxygen, moisture and light protection, good aluminum-layer adhesion and heat-seal performance for food packaging and PP-based laminate development.
VBOPP-GZ01 is a metallized biaxially oriented polypropylene film for packaging that needs protection against oxygen, moisture and light. The reference thickness is 18 μm.
Good aluminum-layer adhesion supports lamination, while the film also provides heat-seal performance under the specified test conditions. It can be combined with suitable PP films to develop polypropylene-based packaging structures.
Recycling compatibility depends on the complete structure, inks, adhesives and local collection and recycling systems.
Confirm barrier performance after converting, seal integrity and product compatibility in the final package.
