Product Features
1. CPP (Cast Polypropylene) Film Features
Superior Physical Properties: High tensile strength, good rigidity, and excellent impact resistance. When used in packaging, the mechanical performance is particularly reliable.
Excellent Optical Properties: The film has high transparency, good luster and low haze, which can clearly display the product appearance and significantly enhance the product’s appeal.
Outstanding Heat Resistance: It remains stable even under high-temperature conditions. The conventional heat resistance can reach 120℃, suitable for heat sealing, sterilization and other high-temperature processing procedures.
Strong Barrier Properties: It has moderate barrier effects against moisture, oxygen and odors, effectively extending the shelf life of food, daily necessities, etc.
Excellent Processing Performance: It is suitable for printing and compounding, and the heat sealing effect is also good, enabling smooth connection with subsequent various packaging processing procedures.
2. CPE (Cast Polyethylene) Film Features
Full Flexibility & Softness: Excellent toughness, soft touch, good extensibility, and it feels extremely comfortable to the touch. It can also fit various irregularly shaped products.
Super Strong Puncture Resistance: Excellent puncture resistance and outstanding tear resistance. It can effectively prevent the product from being damaged during transportation, storage, and use.
Super Reliable Sealing Effect: It can stably heat seal at low temperatures, with a wide temperature range for heat sealing and high sealing strength. The packaging sealing performance is guaranteed.
Chemical Corrosion Resistance: It can resist acids, alkalis, and most chemical substances, suitable for product packaging with requirements for chemical stability.
Suitable for Low-Temperature Environments: Even at low temperatures, it remains flexible and stable in performance, and will not become brittle and crack due to the cold environment.
3. CPP CPE Multi Layer Film Features
Complementary Performance Advantages: By combining the rigidity and heat resistance of CPP with the flexibility and puncture resistance of CPE, the multi-layer structure works in synergy, easily meeting various complex packaging requirements.
Customizable Barrier Performance: Utilizing the multi-layer co-extrusion technology with up to 72 layers, functional layers such as EVOH and PA can be added, significantly enhancing oxygen barrier, moisture resistance, and UV resistance, suitable for high-end packaging needs such as preservation and long-term storage.
Superior Mechanical Strength: The multi-layer structure optimizes the overall tensile, tear resistance, and impact resistance, providing more reliable protection for products compared to single-layer films.
Super-Precise Thickness Control: Each layer thickness can be finely adjusted, ranging from 0.02 to 0.1 millimeters, ensuring uniform film thickness and stable product quality.
Extremely Wide Application Scenarios: Combining the process advantages of CPP and CPE, it can be used for food packaging such as snacks and fresh produce, medical packaging such as disposable medical supplies, and industrial packaging such as electronic components and mechanical parts.
Environmentally Friendly & Cost-Effective: The multi-layer structure reduces waste through precise material allocation, and the film complies with environmental standards and is recyclable, perfectly balancing performance and cost-effectiveness.
