quality Extrusion Coating Lamination Machine & Extrusion Laminating Machine factory

Extrusion lamination is a process by which thermoplastic resins are melted and plasticated in an extruder and the molten polymer is extruded through a T-die as a thin web, which is then coated onto a base material in a nip-roll assembly formed by a steel chill roll and a rubber-covered pressure roll, and finally laminated with one or two kinds of base materials to produce desired laminate product. Step-by-Step Process of Extrusion Coating Lamination: 1. Substrate Preparation The base material (e.g., paper, plastic film, aluminum foil, or fabric) is unwound from a roll.It may undergo pre-treatment (e.g., corona treatment) to improve polymer adhesion. 2. Polymer Extrusion A thermoplastic resin (commonly LDPE, PP, or EVA) is fed into an extruder.The extruder heats and melts the polymer, pushing it through a flat die to form a thin web, molten curtain. 3. Lamination The molten polymer is pressed between the substrate and a chill roll (or another layer in multi-layer lamination).Pressure from the nip roller ensures strong bonding as the polymer cools and solidifies.Laminator consists of chill roll, silicone rubber covered pressure roll, back roll, trimming device, wheelwork device, pneumatic device,etc. It is used to combine molten film with base materials. 4. Cooling & Solidification The coated substrate passes over a chilled roller to rapidly cool and set the polymer layer.This ensures smooth adhesion and prevents wrinkling. 5. Trimming  Shrink-width makes edges thicker, which need to be trimmed, otherwise the laminating film will have some quality problems such as drape, crimp, and unevenness.It is convenient to renew cutter blades and adjust cutting width, thus saving time and labor. 6.Rewinding We have different types of rewinder, it includes double station turret rewinding, double sided roun plate rewinding and other is friction press roll rewinding. It is chosen based on customer’s requirements and products.This auto-splicing rewinder consists of tension control system, splicing device, rectifying device, etc. It can change reels without stopping nor slowing down the machine, thus increases efficiency, reduces waste and saves manpower.  Key Advantages of Extrusion Coating Lamination: ✔ Strong Bonding – Polymer chemically bonds to the substrate.✔ Barrier Properties – Improves resistance to moisture, oxygen, and grease.✔ Versatility – Works with various substrates (paper, foil, films).✔ Cost-Effective – Lower material costs compared to pre-made films.✔ High production speed✔ Environmentally favorable when replacing solvent-based lamination Challenges Requires precise temperature and pressure control Substrate surface treatment (like corona discharge) may be needed to ensure adhesion Equipment investment is relatively high Common Applications: Food Packaging (juice cartons, milk cartons,snack bags) (snack bags) Medical Packaging (sterile barrier films) Industrial Films (moisture-resistant liners) This process is widely used in flexible packaging to create durable, functional materials with improved performance.

Extrusion laminating line is a type of laminating process used primarily in industrial and packaging applications. Extrusion laminating line is a manufacturing process used to bond two or more layers of materials together by melting a thermoplastic resin (such as polyethylene, polypropylene, or EVA) and extruding it as a thin molten film onto a substrate. The molten polymer acts as an adhesive, bonding the substrate to another material when pressed between rollers and cooled.   How Extrusion Laminating line Works: 1.Materials (Webs): Two or more substrates (such as paper, foil, or film) are fed into the laminating machine. 2.Molten Resin: A thermoplastic resin (like polyethylene) is melted and extruded (forced) through a flat die. 3.Application: The hot resin is extruded directly onto one of the substrates. 4.Lamination: The second substrate is pressed onto the molten resin layer. 5.Cooling and Bonding: The materials are pressed together between rollers, cooled, and solidified into a single laminated sheet.   Laiyi packing extrusion laminating machinery to increase the laminating strength, a layer of adhesive chemicals (Ac agent) will be coated on the base material,and therbe dried immediately on line.This process requires a coating device and a drying device. Oven cover is pneumatic with negaive-pressure to prevent hot-air from blowing out of the oven. With segmented temperaturezone, automatic constant temperature control, it ensures easy volatilization of solvents.   Common Applications: Food and beverage packaging (Food and beverage packaging) Pharmaceutical packaging Industrial wraps Flexible packaging (e.g, snack wrappers, pouches) Liquid cartons (e.g, milk, juice boxes) Liquid cartons (e.g, milk, juice boxes)   Extrusion lamination is widely used in flexible packaging due to its efficiency and performance benefits.
