The Benefits and Applications of Bio-Based Hot Melt Adhesives

As businesses aim for more environmentally friendly adhesive options, bio-based hot melt adhesives have become a good choice compared to traditional adhesives. In this article, we will explore what bio-based hot melt adhesives are, how they are made, and the advantages and uses they offer. By understanding this innovative adhesive technology, companies can make informed choices to minimize their impact on the environment and support sustainable practices.

Web adhesive?

A hotmelt adhesive web is a nonwoven fabric with bonding capabilities. It is produced on a roll with a certain width and roll length. It can be applied through a lamination machine with a continuous process. Web rolls could also be cut into a specific form for piece-to-piece lamination. It exists different weight options depending on bonding requirements.

Polyamide hot-melt material and melting point options?

Polyamide adhesive is sometimes referred to as PA adhesive. Depending on polymer structure, it can either be thermoplastic or thermoset. In the case of hot melt adhesive, it belongs to the thermoplastic family. PA hot-melt web is made from Polyamide material. When the material gets heated, it could be activated starting to have an adhesion characteristic. When the temperature goes down, the material will become solid again. From low melt to high melt product range, it varies from 90 to 200 degrees.

In our daily lives, we see textiles everywhere. In various industries, textiles are the foundation for many applications. The textile industry is also likely to innovate more quickly than other industries due to its strong compatibility. Joining materials, such as adhesive, allows combining of various substrates together, adding extra value and functionality.

Apart from that, lamination technology provides a wide range of possibilities. Innovative adhesive web even takes laminating process to the next level due to its clean and made-on roll feature compared to traditional liquid or water-based glue. It allows a continuous lamination process with higher efficiency.

What is a thermoplastic adhesive web?

A thermoplastic adhesive web is a solid material with a nonwoven structure, it’s also called a hot melt adhesive web. When we put it on hand, it feels like fabric. Depending on the machine setting, it exists in different weights and structures.

How is hotmelt adhesive web made?

A perfect adhesive web is formed from a fine fiber that is cooled down into a continuous nonwoven structure. Due to its special structure, it makes the final material very soft, flexible, and breathable.

What are some of the specificities of thermoplastic adhesive web ?

The plastic adhesive web is available in rolls for continuous coating or lamination. Additionally, it can also be made with a paper carrier or a PE carrier to transfer adhesive to a substrate or to avoid tacky problems. For roll length, they are available in 300ml, 500ml, and 1000ml sizes at 76mm inner diameter

It’s really easy to bond it, in 2 steps only!

Why you should use hotmelt adhesive tape for hemming ?

To replace the sewing process
To make the process easier
To reinforce the finishing, and upgrade the quality

Step 1 : Preparation

Make sure your fabric / garment is pre-washed to avoid the narrowing of the hem.
Cut the length of hotmelt adhesive tape you need.

What you need to know about adhesive web width, weight, and roll length.

Hotmelt adhesive web can be categorized from different raw materials, for specification, it can be produced in different widths, weights, and lengths.

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.

Definition of hotmelt adhesive in roll

Hotmelt adhesive is also called thermoplastic adhesive. With different technology and process, it can be manufactured in a roll with different forms, such as Web, Film, Net, and Hybrid.

What is trimmed hotmelt adhesive product, and how to measure it?

A trimmed product means that the edge has been cut. There are two systems that can be applied: circular blade cutting or unwinding cutting. Circular blade cutting can make the edge very straight. However unwinding cutting, the material border is straight, when it get re-winded, the edge is not exactly neat.

How to measure trimmed products?

Hotmelt film adhesive has been used in many applications and industries. In the market, there are a lot of choices. Here we will explain to you how to choose the best film adhesive for your applications.

What is a headliner?

Headliners are made of composite fabrics, a combination of different materials with different functionalities. The composite parts are adhered to the roof of the car and help to improve the interior appeal as well as provide an element of insulation against heat and noise.

A typical headliner consists of multiple layers: a face side, a rigid core in the center, and a backing. The different layers consist of a multitude of materials such as knit or non-woven fabric, rigid foam, reinforcement material, etc. Liquid and dry adhesives (film, web, net) are then used to bond the different layers together in order to enhance the headliner’s unique shape and contours.

What is the function of headliner ?

The multi-layered headliners bring together various functionalities:

better look and comfort through soft touch
stiffness of the roof
absorption of excess noise from the outside
insulation against heat and cold, regulation of internal temperature
improved acoustics for audio systems
