Basic Info
The material can be divided into multiple categories based on actual requirements.
Two-layer composite
• OPP/VMPET; VMPET/PE (commonly used for toy packaging)
• OPP/VMCPP (often used for biscuit/cookie packaging)
Three-layer composite
• MATOPP/VMPET/PE; OPP/VMPET/PE (typically used for facial mask packaging)
• PET/VMPET/PE (commonly used for shampoo packaging)
Four-layer composite
• PET/NY/VMPET/PE, etc. Nylon film (NY) is generally added to enhance the flexibility of the composite bags.
