Functional Properties of CPP Film

Low Friction

Low coefficient of surface friction minimizes resistance between the film and other materials or surfaces.

- Enables smooth film-to-film lamination

- Optimizes performance on high-speed packaging machines (reduces equipment wear, ensuring continuous and smooth operation)

- Prevents film jamming during automated packaging

Good Deep-Drawing Performance

Can be stamped into complex shapes without tearing or structural damage.

- Suitable for making pouches, packaging bags, and custom packaging with complex shapes

- Maintains integrity during forming, suitable for custom packaging designs

Good Heat-Sealing Performance

Forms strong and reliable seals when heated, protecting contents and extending shelf life.

- Essential for food packaging (blocks contaminants, maintains freshness)

- Indispensable for medical packaging (ensures sterility through hermetic seals)

- 各生产批次封口质量稳定一致

高热封强度与复合强度

高温下仍保持较高机械强度，热加工过程中保持完整性。

- 热封后封口依然牢固（防止储运过程中封口失效）

- 适用于多层复合结构（保持膜层间粘结强度）

- 提升重型包装终端产品的耐用性

低结晶点

在较低温度下形成结晶结构，提升柔韧性和加工性。

- 提升柔韧性，便于操作和成型- 提升光学透明度（适合需展示产品的包装，如零食或化妆品包装）

- 降低所需加热温度，简化加工

外观品质一致

在生产和使用全过程中保持均一的外观与物理特性（纹理、颜色、光泽）。

- 满足消费品包装的美观要求（确保品牌一致性）

- 适用于高端产品展示（均匀的光泽/颜色提升产品吸引力）

- 减少品质波动，降低生产损耗

应用重点

多用途包装与工业应用

兼具耐用性、密封性能和一致性，适用于多种应用场景。

- 食品包装（零食、冷冻食品、烘焙食品）

- 医疗包装（无菌器械包装）

- 消费品包装（化妆品、家居用品）

- 工业复合（标签、保护膜）
