What is a Thermoplastic Adhesive Film?

Thermoplastic adhesive film, commonly known as hotmelt adhesive film, is typically presented in the form of a roll. This adhesive solution can be manufactured using different techniques, resulting in either monolayer or multi-layer structures. 

  • Monolayer Thermoplastic Adhesive Film: This film consists of a single layer of adhesive material. 
  • Multi-layer Thermoplastic Adhesive Film: This film combines up to 5 layers coextruded into a single film.  

Examples include: 

  • 3-layer ABA films (Adhesive+Barrier+Adhesive)  
  • 2-layer AB films (Adhesive+Barrier) or 2-layer AA films (Adhesive+Adhesive)

For foam materials, selecting the right adhesive solution is crucial for achieving efficient and sustainable bonding results. One versatile option is thermoplastic adhesive in roll, which effectively bonds various materials, including foams and other technical substrates. In this article, we will explore the important role that this type of adhesive plays in various applications using these materials.

The Versatility of Thermoplastic Adhesives

Thermoplastic adhesives shows versatility by creating durable bonds across different types of materials, such as foams, 3D spacers, felt, non-wovens, technical textiles, or leather. This bonding addresses diverse manufacturing needs, with net, film, and web structures contributing to the improvement of applications in automotive, upholstery, footwear, leather goods, composites, building, and more. Roll-to-roll lamination method allows very low waste and clean results, 1 meter of adhesive equals to 1 meter of laminated material.

Automotive manufacturers have specific needs when it comes to assembling materials. As the market evolves, the need for versatile and sustainable bonding solutions becomes essential. In addition, car interior becomes increasingly customized.

This is where thermoplastic adhesive in roll comes into play.

Thermoplastic adhesive able to bond any material in automotive

Whether you’re working with leather, alcantara, microfiber, PVC, PU artificial leather, foams or technical non-wovens, hotmelt adhesives in roll ensures a seamless and durable bond allowing the best and lasting comfort for the end user. Thermoplastic adhesive provides a consistent and durable bonding. It plays an active role in stabilizing materials so the shape of the part remains the same through time.

Dry lamination is a technique employed in both automotive and industrial applications to bond two or more flexible substrates without the use of solvent-based adhesives or liquids. The adhesive utilized in this process often comes in roll form, which can have various structures like webs, films, or nets.

Using a roll-to-roll method, dry lamination facilitates quick bonding of different substrates. The bonding between the laminated layers is primarily achieved through thermoplastic adhesives such as polyolefin, polyester, co-polyester, co-polyamides, TPU, and specialty blend polymers.

For this roll-to-roll technique, the production line must be equipped with rollers to accommodate both the film or web and the various substrate layers. The thermoplastic adhesive is placed between these layers, and a laminating calender—with adjustable heat and pressure settings—ensures the materials bond correctly.
