PE Aluminum Film Lamination Sheet Extruder

Introduction of PE Aluminum Film Lamination Sheet Extruder

PE aluminum film lamination production line's advantages: stable release tension, smooth and beautiful surface after laminating, strong adhesion with base glue.

Production width: 1000mm to 2000mm

Thickness: 0.6mm-2.0mm.

An aluminumim foil lamination PE sheet extruder is a specialized production system designed to manufacture composite sheets by combining extrusion and lamination processes. Such production lines are commonly used to produce multi-layer sheets or films to enhance properties such as strength, barrier performance, and aesthetics. These laminates are widely applied in industries such as packaging, construction, automotive, and consumer goods.

Key Components of a Lamination Sheet Extrusion Line

• Unwinding device:

  Can be equipped with tension control and web central control systems to meet high demands.

  In the case of process paper, textiles or similar strong-tension materials, no tension control or web central control system is required.

• Drying Oven: 

  Remove moisture or solvents (if applicable) from the adhesive prior to lamination.

• Extruder:

  The central component for melting and homogenizing the raw material (polymers such as polyethylene, polypropylene or polyvinyl chloride). It can be a single or twin screw extruder, depending on the material and application.

• Flat Die:

  Forms the molten polymer into a flat sheet or film. The die design determines the thickness and width of the extruded sheet.

• Lamination Unit (calender roller stack):

  Uses heat, pressure or adhesives to bond extruded sheet to other materials such as foil, paper or other polymer layers. May include nip rolls for precise lamination or heated calender rolls.

• Cooling System:

  Cools the laminate to stabilize its structure and prevent warpage. Typically includes cooling rollers or a water bath.

• Adhesive Application System:

  Applying adhesives (e.g., solvent-based, water-based or hot-melt) to extruded sheets or additional materials prior to lamination. Methods such as roll or spray application may be used.

• Haul-Off Unit:

  Pulls the laminate through the line at a controlled speed to ensure consistent thickness and quality.

• Cutting and Winding System:

  Cut the laminate to the required length or wind it into rolls for packaging or further processing.

• Control Panel:

  A centralized control system (e.g., PLC or touch screen interface) for monitoring and adjusting parameters such as temperature, speed and pressure.

Working Process of a Lamination Sheet Extrusion Line

• Material Feeding: Raw polymer pellets are fed into the extruder where they are melted and homogenized.

• Extrusion: The melted polymer is passed through a flat die to form a continuous sheet or film.

• Adhesive Application (if required): The adhesive is applied to the extruded sheet or additional material (e.g. foil or paper) prior to lamination.

• Drying (if required): The material coated with adhesive is passed through a drying oven to remove solvents or moisture.

• Lamination: In a laminating unit, the extruded sheet is bonded to an additional layer (e.g., foil, paper, or another polymer layer) under heat and pressure.

• Cooling: Cooling the laminate to cure the adhesive and stabilize the material.

• Cutting and Winding: Cutting or winding the laminate to size into rolls for packaging or further processing.

Types of Lamination Sheet Extrusion Lines

• Extrusion Coating Line:

  Extrudes a thin layer of molten polymer onto a substrate (e.g. paper, foil or fabric) to form a laminated sheet.

  This process is commonly used for packaging materials such as milk cartons and food bags

• Extrusion Lamination Line:

  Combines extrusion and lamination processes to bond multiple layers of materials (e.g., polymer, foil, and paper) into a single sheet.

  It is an ideal choice for high barrier packaging applications.

• Co-Extrusion Lamination Line:

  Extrudes multiple layers of different polymers simultaneously to create a multi-layer laminated sheet.

  Suitable for applications that require specific performance, such as barrier or flexibility.

Applications of PE Aluminum Film Lamination Production Lines

• Packaging：

  Food packaging (e.g. snack bags, pouches and wrappers).

  Pharmaceutical packaging (e.g. blister packs and pouches).

  Industrial packaging (e.g. protective films and barrier laminates).

• Construction：

  Waterproofing membranes and roofing materials

  Wall and floor decorative laminates.

• Automotive：

  Interior trim, dashboards and protective films.

  Soundproofing and insulation materials.

• Consumer Goods:

  Laminates for furniture, table tops and decorative surfaces.

  Stationery items such as folders and report covers.

• Printing and Graphics：

  Laminated posters, banners and signs.

  Protective coverings for printed materials.
