What Is Poly Laminated Aluminum Foil?

Poly laminated aluminum foil is a composite material consisting of aluminum foil bonded to one or more layers of polymer film, such as polyethylene (PE). Depending on the application, a variety of adhesives can be used to complete the lamination process. Aluminum polyester laminated foil is a versatile product, available in single-sided laminated polyester foil and double-sided laminated polyester foil, which can be widely used in air ducts, insulation and waterproofing materials, packaging, cables, etc. Poly-laminated aluminum foil has excellent barrier properties to moisture, oxygen, and light, helping to maintain product quality and extend shelf life.

Poly Laminated Aluminum Foil Production Process

Aluminum polyester laminated foil composition:

• Polyester films, such as PE, PET, CPP, BOPP, etc.; or kraft paper, etc.
• Aluminum foil, usually pure aluminum foil
• Adhesives, commonly used polyurethane adhesives, acrylic adhesives, etc.

How is polyester laminated foil produced? Let me tell you!

1. Material preparation: Prepare the aluminum foil and polymer film, which will be used in the lamination process.
2. Bonding: Apply adhesive to the aluminum foil to bond with the polymer film.
3. Dry lamination: The dry lamination process is to press the aluminum foil and polymer film together under heat and pressure. It is usually done using a laminator to ensure that the layers are effectively bonded. The polymer film is usually extruded onto the aluminum foil to form a multi-layer material.
4. Roller printing: Printing aluminum lamination film, printing color, pattern, text, etc. can be customized according to customer needs.
5. Cooling and cutting: After lamination, the material is cooled to fix the adhesive and ensure a strong bond between the layers.
6. Finished product production: Cutting, edge sealing, and other customized processing according to customer needs.

Aluminum Foil Laminated Polyester Film Types

Single Sided Aluminum Poly Laminated Foil: AL+PET

Single-sided aluminum foil composite film (AL+PET) is a composite material that is laminated with a single layer of aluminum foil and a layer of PET film. This structure has excellent barrier properties, mechanical strength, heat resistance, etc.

Double Sided Aluminum Foil Laminated Polyester Film: AL+PET+AL

Double-sided aluminum foil composite film, commonly known as AL+PET+AL, is composed of two layers of aluminum foil with a layer of PET sandwiched between them. The composition of AL+PET+AL provides excellent barrier properties against moisture, gas, and light. Enhanced tensile strength and tear resistance. High temperature resistance, suitable for insulation and heat sealing. Corrosion resistance: the PET layer prevents the aluminum layer from direct contact with external corrosive elements.

Self-adhesive Aluminum Foil Laminated Polyester Material

Self-adhesive aluminum foil laminated polyester material is a multi-layer composite material consisting of a layer of aluminum foil bonded to polyester film and coated with a self-adhesive backing. This material combines the high barrier and reflective properties of aluminum with the durability and flexibility of polyester, enhanced by the convenience of a self-adhesive layer. It is commonly used in insulation, packaging, and industrial applications.

Polyester Film: PET/PVC

Polyester film is a high-performance plastic film made of PET or PVC. These materials are widely used in packaging and electronic applications.
PET film is a transparent, strong, and lightweight thermoplastic material. It is known for its excellent barrier properties, chemical resistance, and optical clarity. It is commonly used in food packaging, electronic insulation, and solar panel components.
PVC film is a flexible, durable material with excellent moisture resistance and mechanical strength. It is used in flexible packaging.

Aluminized Laminating Film

Aluminized laminated film is a multi-layer material consisting of a base film, usually polyester (PET), and a thin layer of aluminum deposited on its surface. The aluminum layer gives the film a reflective metallic look, making it suitable for a variety of applications, from packaging to printing. The composition of aluminized laminated film is as follows:

• Base layer: Usually made of PET or BOPP, it provides durability, flexibility, and clarity.
• Aluminized layer: An ultra-thin layer of aluminum applied by vacuum metallization. This layer provides a metallic look and enhances functional properties.
• Adhesive layer: Applied to the back of the film, it can be easily laminated to substrates such as paper, paperboard, or other films.

Aluminum Foil Laminated Kraft Paper

Aluminum foil laminated kraft paper is a composite material made of aluminum foil bonded to kraft paper, combining the lightweight, durable properties of aluminum foil with the strength and environmental friendliness of kraft paper. This material offers excellent moisture resistance, thermal insulation, and mechanical strength.

Aluminum Foil Cloth

Aluminum foil cloth is a composite material made by laminating aluminum foil to fiberglass or nonwoven fabric. This combination takes advantage of the reflective, barrier, and insulation properties of the foil and the strength, flexibility, and durability of the base fabric. Fiberglass fabric offers high tensile strength, fire resistance, and dimensional stability. Nonwoven fabrics offer lightweight flexibility and cost-effectiveness.

Laser Film

Laser film is a functional film with laser grating effect, showing colorful visual effects. This film is mainly used in decorative packaging, labeling, printing, and anti-counterfeiting fields.
Laser film is usually made of PET, BOPP, or other transparent films. Optical diffraction patterns are formed on the surface of the film by molding, hot pressing, or laser etching technology. The pattern can be a rainbow effect, holographic pattern, or customized text/graphics.

Poly Laminated Foil Features And Advantages

Barrier Properties
Polyethylene laminated foils offer excellent barrier properties against moisture, oxygen, UV rays, and contaminants.
Heat and Temperature Resistance
Aluminum foils offer excellent heat resistance, while polymers provide enhanced flexibility at varying temperatures. Ideal for packaging or ducting applications.
Durability and Flexibility
The lamination process combines the strength of aluminum foil with the stretchability and elasticity of polymers. This ensures reliable performance even when mechanically stressed during transportation or storage. Flexible enough for custom forming and sealing without compromising strength.
Lightweight and Strong
Despite being strong and durable, polyethylene laminated foils are still lightweight due to the thin layers. The lower weight significantly reduces shipping costs if you want to import aluminum polyester laminated foil.
Multiple Customization Options
Can be coated, printed, or colored for specific functions and needs. Enhance packaging appearance with vibrant printing and customizable finishes. Tailor-made to include additional properties such as anti-static or heat-sealable layers.
