As a very important industrial adhesive, hot melt adhesive film plays an important role in all walks of life. Hot melt adhesive film is used as an adhesive, and its main function is to complete the composite bonding of the product. In addition to the composite bonding of the product, it can also be used for product backing. The so-called hot melt adhesive film for back glue refers to these hot melt adhesive film products used as product back glue.
There are many types of hot melt adhesive films, and the applicable industries are also very wide. But as the product back glue, hot melt adhesive film with release paper is generally used. Since it is used as the back glue of the product, it is naturally necessary to apply the hot melt adhesive film to the back of the product. When the hot melt adhesive film is applied to the back of the product using a hot melt adhesive film gluing machine, the hot melt adhesive film will inevitably melt after high temperature heating, and the side connected to the product will be bonded together, and the other side is required Use release paper to ensure that it adheres to other objects to complete the gluing. This process can also be called single-sided composite!
We can use a case to illustrate the use of hot melt adhesive film for adhesive-seamless wall covering adhesive compound. Use the hot melt adhesive film as the back glue of the seamless wall covering (we will not introduce the hot melt adhesive film used in the production process of the seamless wall covering, only the back glue), and select the corresponding size according to the size specifications of the seamless wall covering The hot-melt adhesive film of specifications (select hot-melt adhesive with release paper) is covered on the back of the wall cloth, and the gluing work is completed by a professional compound machine. When the seamless wall covering is pasted to the wall, the release paper is torn off, then hung on the wall, and the corners are fixed to paste the seamless wall covering.
The selection of hot-melt adhesive film for back glue is also selected among hot-melt adhesive films of PA, PES, EVA, TPU and other materials. The specific specifications to be used still need to be selected according to the actual product.
