Characteristics of Laminating and Composite Machines
Release Date:
2026-01-28
A laminating and compounding machine is a specialized piece of equipment that uniformly coats molten plastic film onto the surface of a substrate while simultaneously performing lamination. It features one-step forming, strong adhesion, and broad applicability, making it widely used in packaging, construction materials, hygiene products, and other fields. The machine uses an extruder to heat and melt plastic pellets such as PE and PP, which are then formed into a uniform film through a die. This film is directly applied to the surface of roll materials such as paper, nonwoven fabric, woven fabric, and aluminum foil. Through hot-state bonding and pressure roller compaction, the plastic film is tightly bonded to the substrate, achieving complete lamination without the need for adhesives, resulting in a simple and efficient production process. The finished products exhibit excellent water-, moisture-, oil-, and seepage-resistant properties, with high lamination strength and good peel resistance. The surface is smooth, free of bubbles and wrinkles, and demonstrates strong dimensional stability. The equipment allows adjustment of the coating thickness according to specific requirements and can accommodate substrates of varying basis weights. With its high speed and high output, it is well-suited for large-scale continuous production. The entire machine boasts a high degree of automation, equipped with tension control, web-guidance systems, and closed-loop temperature control, ensuring stable and reliable operation. Compared with adhesive-based lamination, solvent-free lamination is more environmentally friendly and eliminates issues related to adhesive residue; compared with hot-melt lamination, it offers superior overall coverage and better sealing performance. It is commonly used in the production of food packaging paper, laminated nonwoven fabrics, coated woven bags, disposable waterproof tablecloths, and medical-grade seepage-proof substrates.
A laminating and compounding machine is a specialized piece of equipment that uniformly coats molten plastic film onto the surface of a substrate while simultaneously performing lamination, exhibiting notable features such as one-step forming, strong adhesion, and broad applicability. It is widely used in industries such as packaging, construction materials, and sanitary products.
This machine uses an extruder to heat and melt plastic pellets such as PE and PP, which are then formed into a uniform film through a die. The molten film is directly coated onto the surface of roll materials such as paper, nonwoven fabric, woven fabric, and aluminum foil. Thermal bonding combined with pressure roller compaction ensures tight adhesion between the plastic film and the substrate, achieving lamination without the need for adhesives and resulting in a simple and highly efficient production process.
The product boasts excellent water-, moisture-, oil-, and seepage-resistant properties, high composite strength, and superior peel adhesion. Its surface is smooth, bubble-free, and wrinkle-free, with outstanding dimensional stability. The equipment allows adjustable lamination thickness to accommodate substrates of varying basis weights, delivering high speed and high output—making it ideal for large-scale, continuous production.
The entire machine features a high degree of automation, equipped with tension control, web-guidance systems, and closed-loop temperature control, ensuring stable and reliable operation. Compared with adhesive lamination, solvent-free extrusion coating eliminates solvent emissions, is more environmentally friendly, and leaves no adhesive residue; compared with hot-melt lamination, it offers superior overall coverage and better sealing performance. It is widely used in the production of food packaging paper, nonwoven fabric laminates, woven-bag laminates, disposable waterproof tablecloths, and medical anti-permeation substrates, among other products.
