Basic Info
Material Composition of Aluminum-Plastic Composite Bags:
The material can be divided into multiple categories based on actual requirements.
Two-Layer Composite
- OPP/VMPET
- VMPET/PE (commonly used for toy packaging)
- OPP/VMCPP (often used for biscuit/cookie packaging)
Three-Layer Composite
- MATOPP/VMPET/PE
- OPP/VMPET/PE (typically used for facial mask packaging)
- PET/VMPET/PE (commonly used for shampoo packaging)
Four-Layer Composite
- PET/NY/VMPET/PE, etc.
- Nylon film (NY) is generally added to enhance the flexibility of the composite bags.

Frequently Asked Questions (FAQ)
What are the common composite structures for aluminum-plastic bags?
Aluminum-plastic bags can be manufactured in two-layer (e.g., OPP/VMPET, VMPET/PE), three-layer (e.g., PET/VMPET/PE), or four-layer composite structures (e.g., PET/NY/VMPET/PE) depending on the protection requirements of the contents.
Why is Nylon (NY) film used in four-layer composite bags?
Nylon film (NY) is integrated into the composite structure to significantly enhance the flexibility, tensile strength, and puncture resistance of the bags, making them ideal for heavy-duty or sharp items.
What protective features do aluminum-plastic composite bags offer?
These bags provide excellent anti-static, waterproof, UV-resistant, moisture-proof, and light-blocking properties. They also resist oil, cold, and high temperatures, ensuring product integrity under various environmental conditions.
Can I customize the sizes, designs, and colors of these bags?
Yes. We support full customization of designs, dimensions, and external color coatings to match your brand requirements and product specifications.
What industries benefit most from aluminum-plastic packaging?
They are widely applied across the pharmaceutical industry (pill and device packaging), electronics industry (anti-static and semiconductor protection), and various industrial fields (chemical and pesticide packaging).
