Working on more sustainable hotmelt adhesives.

We are living in a world where people are more aware of our planet and our future. We are proud to say, Protechnic, we are part of it. Our R&D department keeps searching for more sustainable and Eco-friendly adhesive materials. We have already succeeded to use some bio-based material. Today, we are even more driven to work in this direction.


In the rapidly evolving landscape of consumer electronics (Speakers, phone, wearable, computer, a new breed of engineering professionals has emerged: soft goods engineers. These experts specialize in the intricate design, prototype and manufacture of products using materials such as textiles, leather, silicone, adhesive and thermoplastic polymers. With their unique blend of mechanical design experience and material expertise, soft goods engineers play a pivotal role in bringing next-generation products to life. 

The Role of Soft Goods Engineers

Soft goods engineers collaborate closely with design teams and manufacturers to develop innovative soft touch solutions for complex structural systems. Their hands-on approach involves working with a wide range of manufacturing equipment, assembling processes, tools, and maintenance procedures. From designing and fabricating soft goods for space exploration to crafting high-altitude applications, these professionals are at the forefront of technological advancement. 


Why Low VOC Consumer Electronics Adhesive Solutions matter for end consumers and workers?

The consumer electronics industry is in a constant state of evolution, marked by an increasing focus on sustainability, environmental responsibility, and product safety. For consumer electronic engineers, whether designing speakers, phones, laptops, wearables, tablets, or notebooks, one of their aims is to innovate and deliver top-tier products.

However, a frequently underestimated critical concern is VOC emission, which is highly related to material choosing. To be more specific, adhesive assembly process plays a crucial factor.


The Sonic Revolution: How Adhesives could increase the Airflow in speakers  

Speakers have evolved beyond just gadgets; they now accompany us through every facet of life, delivering immersive sound experiences that enrich our daily adventures. From the portability of Bluetooth speakers to the immersive audio of home entertainment setups, the demand for superior sound quality is soaring. With the market projected to reach a remarkable $48 billion by 2025, driven by the surge in smart devices and AI-powered assistants, the importance of innovation in speaker design cannot be overstated. Amidst this evolution, adhesive technology emerges as a silent hero, quietly revolutionizing speaker construction and performance. 


The aircraft industry is in constant evolution, with significant innovations in materials. As a result, it’s crucial to find the most suitable options for bonding these materials together. In aviation, several key factors are increasingly vital, including speed, lightweight construction, durability, design, and passenger comfort.

Technological innovations in aircraft interiors drive engineers and designers to seek the latest methods for improved performance continually. Moreover, this sector have stringent standards for aircraft interior applications.


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.
