Packing Stretch Film Roll/Wrap Film/Tubular Film

Materials of Packing Stretch Film Roll

• BOPP: Boasts excellent moisture resistance, suitable for surface printing of flexible packaging products.
• PET: Has strong tensile strength, superior heat resistance, and gas barrier properties. Also, it is well-suited for metallization.
• PA(NY): Colorless with high transparency; excellent toughness and puncture resistance; good cold resistance and oil resistance; used for vacuum packaging, frozen, and high-temperature cooking food packaging.
• PE: Preferred by flexible packaging companies for its high cost-performance ratio and good decorative properties with excellent performance.

Common Composite Materials

• PET: Used as an intermediate composite layer in products to enhance bag stiffness and oxygen barrier properties. Commonly used for machine packaging roll film, high-temperature cooking bags, zipper bags, and other printed materials.
• VMPET: Has oxygen and water barrier properties but inferior to aluminum foil; better puncture resistance than aluminum foil. Generally used in the middle composite layer.
• KPET: Combines all the advantages of KOPP with the high-temperature resistance of PET, commonly used for foods like mooncakes that require oxygen and moisture barrier.
• PE: Has good heat seal performance, low-temperature heat sealing/high heat seal strength, used for packaging milk powder, shampoo, laundry powder, and other chemical products.
• Pe Milky White Film: Good heat sealability, can be used as a heat seal substrate; good cold resistance, suitable for frozen packaging; soft material with good extensibility and toughness, food-grade packaging with high resistance to water, oil, and chemicals, used in daily chemicals, industrial, sanitary packaging, etc.
• Embossed PE: Common embossed materials include milky white spun silk pattern, PE wire drawing pattern, star pattern, milky white perforated film, and non-woven fabric (laminated).
• CPP: Commonly used as printing material for tissue packaging; as a composite material, it is often compounded with other materials as a heat seal layer.
• VMCPP: Has water and oxygen barrier properties but inferior to aluminum foil; better puncture resistance than aluminum foil; has heat seal properties, commonly used in the composite layer for biscuit packaging.
• AL: Excellent heat resistance; best oxygen and water barrier properties; good light reflection and gloss, enhancing display effects; good composite adaptability.
• PA(NY): Colorless with high transparency; excellent toughness and puncture resistance; good cold resistance and oil resistance; good wear resistance and oil resistance; used for vacuum packaging, frozen, and high-temperature cooking food packaging.
• Others PVC: Has shrinkage properties, usually stored in air-conditioned rooms; generally used for bottle labels, single-layer material, printing completed without needing composite.
