Multi-layer laminate: Typically PET (outer for printability) / Aluminum Foil (barrier) / PE (inner sealant). The exterior features a tribal pattern print. Recycled materials such as rPET (Recycled PET) can be used to enhance eco-friendliness
.
Sealing & Construction
3-side heat seal (≥5mm width) for leak-proof integrity
. Tri-seal design ensures strong seams.
Barrier Performance
Moisture Barrier: WVTR (Water Vapor Transmission Rate) is typically low, e.g., <0.5 g/m²/day (with AL foil). Oxygen Barrier: OTR (Oxygen Transmission Rate) is also low, e.g., <0.5 cm³/m²/day·atm (with AL foil). UV Protection: Blocks >99% UV light (280–400nm).
Printing & Customization
Supports high-definition printing
. Customizable tribal patterns, logos, QR codes, batch dates
. Printing options: Up to 10 colors. Finish options: Gloss, Matte, Metallized.
