Extrusion Coating Lamination Machine is an advanced industrial equipment designed for compounding one or more layers of materials through extrusion coating process. It uses high-temperature molten plastic (such as polyethylene, polypropylene, etc.) as adhesive, and heats, melts and extrude plastic particles into a uniform film through the screw system of the extruder. Then, the molten plastic is evenly coated on the surface of the substrate (such as paper, aluminum foil, non-woven fabric, plastic film, etc.) through a specific coating head, and then another layer of substrate is closely attached to the coated substrate through a composite roller to form a new material with composite properties.

• Easy-tear design: By precisely controlling the coating thickness and composite process, an easy-tear design can be formed on the packaging material, making it convenient for consumers to open the package.

Special aluminum-plastic film for battery packaging:

• Battery safety protection: Aiming at the special needs of battery packaging, an aluminum-plastic film with excellent chemical corrosion resistance, high temperature resistance and insulation performance is developed to provide all-round safety protection for the battery.

• Lightweight design: By optimizing the material combination and composite process, the lightweight design of aluminum-plastic film is realized, which reduces the overall weight of the battery and increases the energy density of the battery.

Pre-coated film and paper cup paper:

• Pre-coated film production: The pre-coated film is coated on the surface of the paper to give the paper waterproof, oil-proof, wear-resistant and other properties, which are widely used in printing, packaging and other fields.

• Paper cup paper manufacturing: Using extrusion composite coating technology, plastic film with heat-sealing properties is composited with paper to make heat-sealable paper cup paper, which improves the convenience and hygiene of paper cups.

Tetra Pak packaging:

• Multi-layer composite structure: Through the multi-layer composite process, paper, aluminum foil and plastic film are tightly combined to form Tetra Pak packaging materials with excellent barrier properties and mechanical strength, which are widely used in the packaging of liquid foods.

• Environmentally friendly and recyclable: Tetra Pak packaging materials can be recycled and reused, meet environmental protection requirements, and reduce the impact on the environment.

Non-woven fabrics:

• Functional coating: Plastic films with specific functions (such as antibacterial, waterproof, breathable, etc.) are coated on the surface of non-woven fabrics to give non-woven fabrics new functional characteristics, which are widely used in medical, health, home and other fields.

• Composite reinforcement: Through the composite process, non-woven fabrics are composited with other materials (such as plastic films, paper, etc.) to improve the strength and durability of non-woven fabrics.

Daily cleaning:

• Regular cleaning: After the production is completed every day, the surface of the machine should be cleaned to remove dust, oil and other debris to keep the machine clean.

• Key cleaning of key parts: Key parts such as coating head, composite roller, unwinding and rewinding system should be cleaned to ensure the normal operation of the equipment.
