Web coater for high-viscosity adhesive

Hot Melt Adhesive Extrusion Coating Machine

The hot melt adhesive extrusion coating machine applies high-viscosity hot melt adhesives with poor fluidity such as butyl adhesive, PA, PES, PU, EVA, TPU, etc. for coating. Ideal for processing high-temperature shoe material, luggage, anticorrosive tape, etc. Given the inherent characteristics of hot melt adhesives, a dedicated screw transport device is required, and in some cases, a gear input pump is needed to deliver high-viscosity butyl adhesive through the applicator head for appropriate coating.
  • Hot Melt Adhesive Web Extrusion Coating Machine
    Hot Melt Adhesive Web Extrusion Coating Machine, JYJ

    Hot melt adhesive web extrusion coater operates by extruding adhesives through a die onto a moving web or substrate. This process creates a uniform and controlled adhesive layer, preparing the coated web for various applications like labeling, packaging, and laminating.

Frequently Asked Questions

The roll-to-roll processing is a film processing method that embeds, coats, prints, or laminates various fluid materials onto flexible rolling substrates, and then continuously transports the material from one roll to another (unwind to rewind).

Compared to other coating technologies, roll coating has several advantages. When coating on flat substrates, it is easy to control the uniform deposition of precise thickness, and the amount of liquid required can be pre-measured.

The effectiveness of roll-to-roll processing depends on the accuracy of web tension control. When the web moves from one roll to another, tension control is crucial to production. Tension must remain constant and uniform throughout the roll-to-roll process. Any slight variation in tension could compromise the stability of the material applied to the substrate.

Hot melt adhesive is coated onto the substrate in a thermoplastic state. In some applications, the material is only used for changing the surface of the material, but the more common purpose is to bond two layers of material together to build a composite material, namely a laminated plate. Therefore, the bonding process is often referred to as laminating coating.

These solid adhesives (in block or granular form) must be melted before use. They have a short curing time. Common materials include polyether, olefin, rubber, EVA, and PA.

All hot melt adhesive systems are equipped with low-tension roll-to-roll paper transport drives and use load cells and dancers to measure tension. The control system adjusts based on the set values. Multiple web alignment systems ensure proper alignment of the web layers for coating and lamination. Accumulators (rolls and belts) ensure uninterrupted continuous processes during batch changes.

Coating is a process of applying an extra layer on a substrate, endowing it with additional characteristics or functionalities. Hot melt adhesive extrusion coating is a process in which a hot melt adhesive, which is a thermoplastic material, is applied onto a substrate using an extrusion method. This technique involves melting the adhesive material and then extruding it through a slot die onto the substrate.

Hot melt adhesive extrusion coating applies various substrates and adhesives. Substrates include film, paper, plastic, metal, etc.; adhesives include butyl adhesive, PA, PES, PU, EVA, TPU, etc.

Along with other equipment, our hot melt adhesive extrusion coating machine can participate in the productions of adhesive tape, barrier film, waterproof film, shoe materials, single-sided fine cloth, ping peng coating, toe puff counters, self-adhesive labels, etc.
