Problems encountered in the use of hot melt adhesive film. Knowledge of hot melt adhesive film. Hot melt adhesive film is a material adhesive applied to two materials of the same or different materials. It is in great demand in the industry. As a high-viscosity high-tech material, it is necessary to understand the product characteristics of hot melt adhesive film before purchasing products. This will be more reasonable. It will also be more handy when applying it. Then Xiaobian will share with you the product features and applications of hot melt adhesive film.

1. What material do you need to bond? Different materials of hot melt adhesive have different bonding fastness to different materials. There is no glue that bonds all materials better than all other glues, such as polyurethane for textile fabrics. Very strong, while the bonding strength to PE plastic is almost zero;

2. How much temperature heating your material can withstand. For example, the maximum temperature resistance of your material cannot exceed 130 °C, then you have to choose a hot melt adhesive with a melting point lower than 130 °C, because if the processing temperature cannot reach the melting point of the glue, the glue does not melt, and the adhesive force is almost zero;

3. Do you need to consider the softness of the product after you glue it? Should it be applied in a high temperature or low temperature environment? Should it be washed with water? Should it be dry cleaned? For the above requirements, it is necessary to choose a film with the above corresponding properties.

4. If there are a variety of glues to choose from, choose a cost-effective glue; if it can meet your bonding requirements, choose the thinnest glue (the thinner the glue, the cheaper the price).
