Hot melt adhesive film is a malleable adhesive with a specific temperature range. Its physical state changes with the temperature, but the chemical properties remain unchanged; it is non-toxic and tasteless and an environmentally friendly chemical product.
Hot melt adhesive film is a bonding material applied to two substances, the same as double-sided tape. With superior bonding performance and strong resistance to washing, it has become a heat transfer material for the seamless bonding of many heat-resistant textiles. It has a low melting point, high elasticity, dry/wash resistance, colorless and transparent, abrasion resistance, cold resistance, acid resistance, anti-mold, and anti-bacterial properties.
Several major hot melt adhesive films include PES, PA, EVA, and TPU. These hot melt adhesive films are ideal for environmentally friendly bonding materials.
Hot melt adhesive film is widely used in embroidery labels, armbands, trademark bonding, suitable for clothing, shoes, hats, bags, medical, military coats, sportswear, toy products, and other fields. Firm adhesion, easy operation, low cost can replace the traditional turning needle.

Hot melt adhesive film is divided into two categories, thermoplastic hot melt adhesive film, and thermosetting rerongjiaom, according to the use characteristics, with the following features.
1、Good consistent and uniform adhesive thickness.
2、Easy processability, solvent-free, and easy to process.
3、Good adhesion to many objects.
4、Thickness of 0.1-0.203MM, the color of translucent/amber.
5、Can be punched and cut into precise shapes and sizes, suitable for purely manual or automated applications
Hot melt lamination is a process in which two or more layers of materials are fused together with adhesive dots. Its properties depend on the type of polymer, molecular weight, and process. It has a relatively low viscosity and is heat and moisture resistant. Its tack (or wetting ability) is controlled by a resin that controls the amount of adhesive emitted by the material.
The manufacturing process is complex and can involve multiple materials, such as polyethylene and a variety of other substrates. The most important factor in this process is adhesion, which can be tricky to achieve. The adhesive is the key to the final product's appearance. Therefore, it is important to choose the right kind of adhesive based on the desired look and the substrate's requirements. The following are some common characteristics of hot melt lamination films.
The adhesives used in hot melt lamination are often called super-glues because they bond two surfaces. They are very strong, and they can hold up under tough conditions. This is one reason why hot melt lamination is so popular. These films are available in rolls as long as 500 feet. Unlike most other lamination films, they do not require a liner. They bond instantly with heat when activated. The film contains virtually no water, and the laminated materials are ready for cutting immediately after application.
Unlike traditional dry lamination, hot melt glues don't expose the substrate to direct heat. They do not require a drying step, which can use up a lot of energy. They are also more flexible and tough than other lamination methods. Aside from being environmentally friendly, they can provide a high level of productivity.
Hot melt adhesives have a number of advantages over solvent-based adhesives. They are more flexible and environmentally friendly than solvent-based adhesives. In addition to being environmentally friendly, hot-melt adhesives are also better for the environment than their dry counterparts. Because hot melt is highly reactive, it is a more environmentally friendly alternative than solvent-based ones. Compared to traditional dry lamination, it is also faster and more effective.
In fact, it is present in almost every electronic device on the planet. Because of this, it is necessary to use industrial hot melt with special properties that will not damage sensitive electronic components or withstand vibrations.
Another advantage of hot melt adhesive is that it is 100% solid, but becomes liquid once it is heated. Its melting temperature ranges from 80 to 200 degrees Fahrenheit, and it cools to its solid form. It is also important to note that hot melts are not completely solid, and they can become brittle or break when exposed to cold temperatures. However, they do not break easily. Hence, it is important to ensure that they meet the specific requirements of the lamination process.
For example, in the construction of electronic devices, these films can be used as a protective layer. Other types of adhesives are used to create different kinds of packaging. Aside from these, there are numerous types of films. The most common are BOPP, nylon, and PET. These materials are used for a variety of applications. The different types of adhesives used for lamination can also be thermal and wet bonding.
Hot melt adhesives are applied using different methods. In the first method, the adhesives are heated in an off-line melting unit and are then delivered to a hot melt coating unit. This type of adhesive is applied using conventional processes such as gravure, slot die, and knife-over-roll. In the second method, hot melt adhesives are fused with other materials to form a multilayer laminate. These films can be used to bond many different types of materials.
