Hot melt adhesive film, often referred to as hot melt double-sided tape, is an extremely versatile bonding material. Its applications are so vast that they often appear in unexpected places. It can be found in the clothes you wear (e.g., interlinings for underwear, shoe material lamination), the electronics you use (e.g., smartphone screens, battery packaging), the cars you drive (e.g., interior trim, roof liners), and the furniture and decorative materials in your home. As an efficient and environmentally friendly bonding solution, it works behind the scenes to join products across numerous industries.

How is Quality Hot Melt Adhesive Film Produced?

Producing high-quality hot melt adhesive film requires precise processes and advanced equipment. The primary production techniques include knife coating and extrusion coating. The chosen technique determines the film's thickness, precision, and ultimate field of application.

Jiayuan's Production Solutions:

Knife Coating Process & JYJ Coating Machine

Jiayuan Machinery specializes in the knife coating process and has developed the high-performance JYJ series hot melt adhesive Film coating machine. We offer a one-stop service, from equipment to technical support, and can customize solutions based on specific client requirements.

Features of the JYJ Series Hot Melt Adhesive Film Coating Machine:

Extensive Material Compatibility: This machine is suitable for processing various high-viscosity hot melt adhesives or thermoplastic materials, with a broad viscosity range of 3,000 - 150,000 cps. It is particularly well-suited for handling high-viscosity adhesives like high-temperature polyamide (PA) and polyester (PES).

High Precision & Flexibility: By replacing the melt pump and precision coating head, different thickness and precision requirements can be easily achieved. Additionally, switching rollers allows for specific coating effects like matte or gloss finishes.

Stable Adhesive Supply System: The screw-type continuous adhesive supply system ensures extremely stable output volume and pressure, which is crucial for producing hot melt adhesive film with uniform thickness and consistent quality.

High Production Efficiency: The integrated high-efficiency cooling system rapidly solidifies the adhesive film, enabling high-speed coating and significantly boosting production output.

Extrusion Coating Process & Lamination Machine

Besides knife coating, hot melt adhesive film can also be produced using the extrusion coating process. Jiayuan's extrusion coating machines use coating-grade resins like PP, EVA, and EAA as raw materials. The resin is melted and extruded to form a film, which can be applied to substrates such as paper, non-woven fabric, woven fabric, and aluminum foil for single or double-sided lamination. This process is ideal for producing large-area, heavy-duty composites that require strong sealing.

Success lies in cooperation, and cooperation leads to mutual benefits. Jiayuan Machinery meticulously manufactures hot melt coating and lamination machines. We warmly welcome both new and existing clients to visit us for discussions on development and to explore a promising future through communication and negotiation.
