Material Properties & Advantages
The plastic layers in the aluminum-plastic packaging films are typically made of materials such as polyethylene, polypropylene, or polyester. These materials provide excellent flexibility, durability, and resistance to tearing, puncture, and impact. The aluminum layer, which is usually around 6 to 9 microns thick, acts as a barrier to moisture, oxygen, and light. The aluminum layer also provides a glossy finish to the packaging, making it more visually appealing.
Key Advantage: One of the advantages of using aluminum-plastic packaging films is that they can be easily printed on, allowing for branding and product information to be displayed. Additionally, the films can be easily heat-sealed to create a secure and airtight seal, which helps to maintain product freshness and prevent contamination.

Frequently Asked Questions (FAQ)
What is the structural difference between H-088-GF and H-088-GR packaging films?
H-088-GF features a CPP outer layer (Nylon 15um / DL3 / AL 35um / DL3 / CPP 35um), while H-088-GR utilizes a PP layer as the inner sealant layer (Nylon 15um / DL3 / AL 35um / PP 35um).
What materials are typically used for the plastic layers in these films?
The plastic layers are usually made of high-quality polyethylene, polypropylene, or polyester to ensure maximum flexibility, durability, and resistance to tearing and puncture.
What is the main function of the aluminum foil layer?
The aluminum layer acts as a highly effective barrier against moisture, oxygen, and light, preserving product freshness while providing an aesthetically pleasing glossy finish.
What is the standard thickness and formability of these films?
The typical thickness is 88±5% μm, and the formability (for a size of 34mm x 44mm) is rated at ≥4.5 mm according to the test standards.
How well do these packaging films resist electrolytes?
Based on the technical data, the resistance to electrolyte has a peel strength rating of ≥5 N/15mm, ensuring high chemical stability and safety.
