Aluminum-Plastic Composite Film

Product Overview

Aluminum-Plastic Composite Film is a high-performance laminated material engineered by combining layers of aluminum foil with specialized plastics (e.g., PET, NY/PA, CPP, or PE) using advanced dry or thermal lamination technologies. This multi-layer structure creates an exceptional barrier against moisture, oxygen, light, gases, and contaminants, making it ideal for industries requiring stringent protective packaging, such as food, pharmaceuticals, electronics, and lithium-ion batteries. The film ensures long-term preservation, durability, and reliability under extreme conditions, including high temperatures and corrosive environments.

Features & Advantages

• Superior Barrier Performance: Provides an excellent shieldagainst moisture, oxygen, UV light, and gases, ensuring product freshness and longevity.
• Excellent Mechanical Strength: Resists puncture, tearing, and abrasion, maintaining integrity during transportation and handling.
• High & Low-Temperature Resistance: Withstands temperatures from -50°C to 121°C(or higher, e.g., for steam sterilization), suitable for retort packaging and frozen storage.
• Chemical & Corrosion Resistance: The inner plastic layer (e.g., CPP) resists strong acids, electrolytes, and solvents, making it ideal for battery and chemical packaging.
• Lightweight & Flexible: Easily processed into rolls, sheets, or custom-shaped bags, reducing logistics costs while offering design versatility.
• Eco-Friendly & Safe: Free of toxic solvents and odors; complies with international food and pharmaceutical safety standards.

Applications

Aluminum-Plastic Composite Film is widely used across industries for its protective and preservative properties:

• Food & Beverage: Retort pouches (ready-to-eat meals), dry foods, powdered products, and aroma-sensitive items like coffee and spices.
• Pharmaceutical & Healthcare: Blister packs for pills, intermediate drug packaging, and sterile medical device packaging.
• Electronics & Batteries:
  • Lithium-ion Battery Encapsulation: Protects battery cells from moisture and external damage (structures: ON/AL/CPP).
  • Electromagnetic Shielding: Used in cables and electronic components.
• Industrial & Consumer Goods: Shields precision machinery parts, automotive components, and chemicals from environmental damage.

Frequently Asked Questions (FAQ)

1. How does Aluminum-Plastic Composite Film provide barrier protection?

The aluminum foil layer blocks moisture, oxygen, and light, while the plastic layers (e.g., PET, CPP) add mechanical strength and sealing capabilities. Together, they create a highly resistant barrier against external factors.

2. Is the film suitable for high-temperature applications?

Yes. The film can withstand high temperatures (e.g., up to 121°C or higher for steam sterilization), making it ideal for retort food packaging and medical sterilization processes.

3. Can the film be customized?

Absolutely. We offer customization in thickness, width, layer structure, and printing. Colors, logos, and surface treatments (e.g., anti-fog) can be tailored to your needs.

4. How is the film laminated?

We use dry lamination (adhesive-based) or thermal lamination (heat-based) technologies. These methods ensure strong interlayer adhesion without bubbles, delamination, or curling.

5. What is the shelf life of products packaged with this film?

Depending on the application, products can achieve a shelf life of up to 12 months or more due to the film’s high barrier properties.

6. Does the film meet international safety standards?

Yes. Our films comply with EU and North American environmental regulations, including RoHS and FDA standards for food contact safety.

7. What are the key considerations for battery-grade film (e.g., for lithium-ion batteries)?

Battery-grade film requires:

• High ductilityfor deep drawing without rupture.
• Strong resistance to electrolytesto prevent corrosion.
• Excellent seal integrityto maintain battery performance.
