quality Extrusion Coating Lamination Machine & Extrusion Laminating Machine factory

Packaging extrusion laminating is a process that applies a molten plastic layer (such as PE, PP, or EVA) onto substrates like paper, plastic films (BOPP, PET, CPP), aluminum foil, or nonwoven fabric. The laminated structure provides strong bonding, excellent barrier properties, and improved sealing performance. Widely used in food packaging, medical packaging, industrial bags, and paper-based coatings, extrusion laminating offers high efficiency, cost-effectiveness, and an eco-friendly alternative to adhesive lamination. Packaging Extrusion Laminating important comopnents include Extuder,Laminator,Unwinding..... Extuder Laiyi patented screw, with characteristics of high revolving speed, high shear, high mixing, wear-resistant and energy-saving, can ensure the temperature difference between die lips and the polymer coming out of the die less than 30°C, which will greatly enhance the peeling strength. The inner surface of the barrel and the surface ofthe screw are centrifugallycast with alloy, which has the characteristics of anti-corrosion and wearresistance, lts service time is usually three times of the ordinary screw. Laminator Laminating unit consists of chill roll, silicone rubber covered pressure roll,back roll, edge trimming device, wheelwork device, pneumatic device,etc.The rolls are equipped with quick-disassembly gauge to save time forroll-changing and prevent chilling water from causing a mess at site. Unwinding (Shaftless Unwinder) Two or more rolls of substrate (e.g., paper, foil, film) are mounted on unwinds. These substrates, known as "webs," are fed into the machine. Primary Substrate: Often the functional layer (e.g., aluminum foil for barrier, paper for stiffness). Secondary Substrate: Often the sealant or printable layer (e.g., polyethylene film). Extrusion laminating is a foundational technology for producing high-performance, durable, and protective flexible packaging. Its ability to combine diverse materials into a single, robust structure makes it indispensable for industries demanding extended shelf life, product protection, and functionality—from food and beverage to pharmaceuticals and medical devices.

Main Unwinder: The Unwinding equipment consists of unwinding tension control system,material receiving devices,and  deviation-recti-fying  device and some other devices. From thin to thick basic materals,the precision tension control system of high-performance frequency conversion motor can prevent wrinkles happened during the acceleration,deceleration,high speed roll changing periods,and reduce materal loss to the minimum.The one click air operated chuck for clamping base material helps realizing the continuous roll changing of the basic materials. The unwinder has two types:double station flipping type automatic unwinder and cup paper unwinder with roll stand. Laiyi Extrusion Coating Laminating Line Double station unwinder: 1.Unwind diameter: Φ800mm,Φ1200mm；2. lt applies to multiple materi-als and has a wide range of uses:3. lt can automatically change rolls without stopping machineor reducing speed:4.lt has one-button andno-button type operation, is simple and convenient:5.lt occupies small area, can save the production space.

An EVA (Ethylene-Vinyl Acetate) film extrusion line is a complete set of industrial machinery designed to transform raw EVA copolymer pellets into a thin, continuous, and uniform film. This film is prized for its excellent clarity, flexibility, softness, toughness, and strong sealing properties. EVA films are widely applied in solar panel encapsulation, laminated glass, packaging, and decorative materials. Laiyi film extrusion laminating line PERFORMANCE,ADVANTAGES: This line adopts vertical oven to ensure the drying performance and save the equipment space. Double station turret shaftless unwinder and rewinder ensures the stability of auto-splicing without reducing line speed. EVA Film Extrusion Line Extrusion Process: EVA resin is melted in an extruder. The molten EVA is extruded through a T-die (flat film extrusion) or a circular die (blown film extrusion). Film is cooled, stretched, and wound. Temperature Control: Precise heating/cooling system to prevent premature crosslinking of EVA.EVA Film Extrusion Line Components: Extruder (usually single-screw or twin-screw)LaminatorPLC Operation CabinetChill roll unit or air ring or three rollers chilling (for cooling) Corona treatment system (to improve adhesion) Thickness control systemAutomatic winding system(Friction Rewinder) Would you like me to prepare a professional product description of an EVA film extrusion line (like a brochure/website text), or a technical process overview (for engineers)?

A PP film extrusion laminating line is a specialized production system,used to manufacture laminated films by extruding polypropylene (PP) and bonding it to one or more substrate materials (such as fabrics, nonwovens, aluminum foil, or other plastic films).This process enhances the material's properties, including strength, barrier resistance, and durability. Here’s a professional breakdown: PP film extrusion laminating line purpose Combines PP film with base materials such as paper, woven fabric, nonwoven fabric, aluminum foil, or BOPP film.Improves barrier properties (moisture, grease, chemicals), mechanical strength, and printability. PP film extrusion laminating line Main Components 1.Unwinder(s) – Feeds base materials into the line. 2.Extruder – Melts PP resin pellets into a molten film. Extruder 3.Die/Extrusion T-die – Spreads molten PP evenly over the substrate. 4.Chill roll unit – Rapidly cools and solidifies the PP film. 5.Laminating station – Presses layers together under controlled temperature and pressure. 6.Rewinder – Rolls the laminated material for downstream processing. PP film extrusion laminating line Process Flow 1.Substrate feeding → 2. PP resin melting & extrusion → 3. Molten film coating → 4. Cooling & solidifying → 5. Laminating → 6. Rewinding.

"Release paper extrusion laminating" refers to an extrusion lamination process where a molten polymer (such as polyethylene) is coated onto release paper to create a functional layer. Release paper is a specially treated paper with a non-stick surface (often silicone-coated) used as a carrier or protective backing for adhesive materials, labels, tapes, and composite products. In extrusion laminating, the polymer layer bonds the release paper to another substrate (like film, foil, or fabric), or enhances the paper’s barrier, strength, or heat-sealing properties.This technique is commonly used to produce materials for various applications, including flexible packaging, release liners for labels and tapes, and more.  Laiyi Double Side Release Paper Extrusion Laminating Machine Performance and Adwantages: Using high speed, high shear, high mixing, large extrusion capacity,wear-resistant and energy saving screw independently developed by Laiyi. To ensure a large amount of extrusion,the temperature gap between the resin temperature and the mold deslgn is less than 30 degrees, which greatly improves the stripping strength after the film is sprayed. The inner wall of the cylinder and the surface of the screw are centrifugally cast with special technology which has the characteristios of corrosion resistance,super wear resistance and long service life, which is three times the service life of the ordinary screw. Turnplate type rewinding and unwinding, ensure the stability of roll change under the condition of speednot reduced. The Process: The extrusion laminating process involves several key steps: Extrusion: A thermoplastic polymer, often polyethylene (PE) or polypropylene (PP), is heated to its melting point and extruded through a die (a narrow opening). Lamination: The molten polymer is extruded directly onto the release paper, forming a thin, even layer. Cooling and Rewinding: The laminated material is then cooled and wound onto a roll.  Unwinding: Paper substrate is fed from a roll into the laminating system. Priming/Corona Treatment: Surface treatment improves adhesion. Trimming & Rewinding: Finished product is trimmed and wound into rolls. If you need, I can also give you a more polished definition suitable for catalogs or product descriptions.
