Composite Film

PET (Polyethylene Terephthalate): As the outer layer, PET offers excellent mechanical strength, high tensile strength, and good dimensional stability. It has high transparency, enabling clear visibility of the packaged products, which is beneficial for display. Additionally, PET has good resistance to heat and chemicals, and it provides certain barrier properties against gases and moisture.

Strength: MDOPE (stretched in machine direction) offers Superior tensile/puncture resistance for Durability with heavy/sharp items.

Strength and Stiffness: PP outer layer offers high tensile strength and dimensional stability, resisting sagging under load.

Strength: XPP’s cross-linked structure delivers high tensile/puncture resistance; PE adds Flexibility.XPP resists chemicals/oils; PE blocks moisture, protecting contents.

PE (Polyethylene): Serves as the inner layer. PE has good heat - sealing performance, enabling strong and reliable seals when heated. It also offers good chemical resistance and flexibility, making it compatible with a wide range of products. The combination of PA and PE leverages the strengths of both materials to create a versatile composite film.

• Outer Layer (OPP Film):
  • • High transparency, allowing clear visibility of the packaged products.
    • Excellent printability, suitable for high-definition patterns, logos, or product information.
    • Good mechanical strength, with high tensile and impact resistance.
    • Water and moisture resistance, protecting contents from external humidity.
• Inner Layer (CPP Film):
• • • Heat-sealability, enabling strong and reliable sealing to prevent leakage.
    • Soft texture, providing flexibility for easy filling and handling.
    • Chemical resistance, compatible with most dry or semi-dry substances.

High Tensile Strength: PAPA/PET/MDOPE/PP/XPP/OPP layer allows the film to withstand significant pulling forces, resisting deformation during transportation and handling.

Good Puncture Resistance: Protects against piercing by sharp edges or particles, ensuring packaging integrity and preventing leakage.

Excellent Flexibility: Conforms easily to irregularly shaped products, facilitating versatile packaging.

Superior Heat - Sealing Performance: PE layer forms tight seals, preventing entry of air, moisture, and microorganisms.

Good Chemical Resistance: Resists corrosion from most acids, alkalis, and solvents, suitable for chemical - contact products.

Low Temperature Resistance: Maintains mechanical properties and flexibility in low temperatures, ideal for frozen goods.

Combined Material Benefits: Integrates PA's strength and puncture resistance with PE's heat - sealing and chemical resistance for balanced performance.

Versatility: Suitable for a wide range of industries and product types, from food to electronics.

Cost - Effective: Offers good performance at a reasonable cost compared to more specialized films.

Processability: Compatible with various packaging machinery, enabling efficient production.

Sustainability Options: Some variants are available with recyclable properties, aligning with eco - friendly packaging trends.

Medical Device Packaging: Barrier properties and sterility maintain the sterility of syringes, needles, and gloves before use.

Pharmaceutical Packaging: Blister packs made from this film protect tablets and capsules from moisture, light, and contamination.
