In today’s industry, sustainability has become a necessity. One aspect of sustainability is promoting a circular economy, where materials can be reused and recycled at the end of their life. But what about the adhesives that bond these materials together? 

Thermoset adhesives can often represent a challenge for recycling as the material is fixed after the activation. Here at Bemis-Protechnic we offer thermoplastic adhesive solutions that are tailored to match the composition of your substrates. That approach allows easier streamlined recycling at the end of your product’s life cycle. 

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. 

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)

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.
