HOT MELT TAPE AND MANUFACTURING AND USING METHOD THEREOF
20220332981 · 2022-10-20 ·

The present disclosure provides a hot melt tape at least including a substrate, an adhesive layer, and an anti-sticking layer, wherein the anti-sticking layer is adjacent to the adhesive layer and is the outermost layer of the hot melt tape. The hot melt tape may be used to seal objects, and preferably is made of a multilayer co-extrusion process. The anti-sticking layer prevents the hot melt tape from sticking the objects without needing a release film, and the hot melt tape can be directly heated during sealing the objects.
