Due to its odorless, non-toxic and environmentally friendly properties, hot melt adhesives are used in the packaging and assembly of many daily necessities. For example, the product packaging of cosmetics uses hot melt adhesives and hot melt adhesive machines, from packaging cartons to lipstick tubes, cream caps, perfume caps, spray heads, perfume caps, eyelash tubes, etc. of the product itself.

Because the volume of cosmetics is relatively small, it is usually glued by spraying glue quickly. During production, a hot-melt glue machine is used together with hot-melt glue tubes, glue guns, and conveyor belts. The hot-melt glue guns and cosmetic components are positioned, and the hot-melt glue machines and conveyor belts are turned on for dispensing with flowing water, by manual bonding. This production method has high efficiency, fast response, and glue spraying does not drag, and can effectively control the amount of hot melt glue, reducing costs for enterprises.
