Products Description
Composite plastic bags are engineered by bonding multiple layers of film, typically divided into three key components:
1. Base Layer: Enhances visual appeal, supports high-quality printing, and provides moisture resistance, ensuring products look attractive and remain protected during storage.
2. Functional Layer: Offers critical barriers against oxygen, light, or moisture, preserving product quality. This layer is especially vital for sensitive items like food, pharmaceuticals, or electronics.
3. Sealing Layer: Directly contacts the packaged goods, featuring excellent heat-sealing properties, transparency, and resistance to chemicals or oils. It ensures a secure, leak-proof seal while maintaining product integrity.
These multi-layered structures are manufactured using food-grade plastics, fully biodegradable materials, or antimicrobial/anti-mold formulations, catering to strict safety and sustainability requirements.
