As an important adhesive in the composite industry, hot melt adhesive film can meet the composite bonding of products in many industries by virtue of its rich specifications and characteristics. For example, we are particularly familiar with the products that need to use hot melt adhesive film composite in the building materials industry: seamless wall coverings, curtains, carpets and even furniture wood panels.
The type of hot melt adhesive film used in the building materials industry is not just a single specification. For example, there are two types of hot melt adhesive films used in the composite of seamless wall coverings, namely: EVA hot melt adhesive film and PA Of hot-melt omentum. EVA hot-melt adhesive film is coated on the back of seamless wall covering as a back glue; PA hot-melt net film is mainly used for composite processing of wall covering. Of course, what I want to introduce to you today is a kind of hot adhesive called perforated hot melt adhesive film.
Perforated hot melt adhesive film is literally a perforated hot melt adhesive film, so why punch holes on the hot melt adhesive film? What is the difference between a perforated hot melt adhesive film and a non-perforated hot melt adhesive film? Can all hot melt adhesive films be perforated?
1. Why punch holes in the hot melt adhesive film? Punching holes in the hot melt adhesive film is mainly to solve the problem of air permeability, because the air permeability of the hot melt adhesive film is not particularly good, but there are some materials that use the film composite to have a better effect than the mesh film, but it is more effective for the air permeability. For higher requirements, perforated hot melt adhesive film can be used.
2. What is the difference between perforated hot melt adhesive film and non-perforated hot melt adhesive film? The main difference between the two is the air permeability. The bonding strength and characteristics of the perforated hot melt adhesive film of the same specification and the unperforated hot melt adhesive film will not change, but the air permeability of the perforated hot melt adhesive film is even more called.
3. Can all hot melt adhesive films be perforated? In theory, all hot melt adhesive films can be punched, but currently the hot melt adhesive films that need to be punched are mainly EAA hot melt adhesive films. EAA hot melt adhesive film is a hot adhesive with high bonding strength.
4. What is the application range of perforated hot melt adhesive film? Perforated hot melt adhesive films are currently mainly used in the processing and production of automotive interiors and sanitary materials, such as the composite of carpet assembly in automotive interiors and the composite of automotive interior flannels; sanitary napkins are mainly used for sanitary materials. , Diaper pads and other compound use.
