ShiJiaZhuang City JingHua linging cloth addresses the frequently asked question about the bonding effects of hot melt adhesive films, especially during the summer. Many individuals wonder whether hot melt adhesive films can maintain a strong bond in high-temperature seasons. Why does the bonding of hot melt adhesive films often result in weak adhesion and easy detachment• In this article, we will briefly discuss why the hot melt adhesive film you use may not bond effectively.
Concerning the issue of poor bonding effects with hot melt adhesive films, we have previously shared some insights in several articles. Readers who have been following us may already have some understanding of this issue. In this article, we will systematically introduce the reasons for the weak bonding of hot melt adhesive films:
Supplier Quality Issues: If you are using hot melt adhesive films from small-scale manufacturers, there may be quality concerns. Some small factories may use inferior materials to reduce production costs or may have technical limitations, resulting in defective hot melt adhesive films.
Incorrect Type Selection: No single type of hot melt adhesive film can be compatible with all materials. Confirm whether the type of hot melt adhesive film you are using is compatible with the composite material.
Mismatched Specifications: In addition to selecting the wrong type, it may also be a matter of using specifications that do not meet the requirements. For example, if you need to use a 30-gram hot melt adhesive film, but you choose to use a 20-gram film, the insufficient thickness may lead to weak bonding.
Outdated Equipment: Apart from issues with the product itself, the bonding effects may be affected by outdated composite equipment that cannot meet the demands of hot melt adhesive films, resulting in poor bonding.
By understanding these potential reasons, you can make a more informed choice when selecting a hot melt adhesive film that suits your needs, ultimately improving the stability of bonding effects.
