What exactly is "hot pressure-sensitive adhesive" (hot melt pressure-sensitive adhesive)?
It is a type of adhesive that is applied by heating and melting, and forms a pressure-sensitive adhesive (i.e., pressure-sensitive adhesive) film upon cooling.
You can understand it as a combination of the stickiness (pressure-sensitive property) of sticky notes and the application method (hot-melt property) of hot melt adhesive sticks.
Main features and advantages:
Environmental protection: It usually has a 100% solid content, contains no solvents or water, and has no VOC (volatile organic compounds) emissions during production and use, making it more environmentally friendly and green.
High efficiency and fast drying: It adheres immediately upon cooling, eliminating the need for long waiting times for drying or curing. It is highly suitable for high-speed automated production.
Strong initial adhesion: It immediately becomes sticky after cooling and can quickly fix items.
Convenient for storage and transportation: The raw materials are solid and non-flammable, ensuring safe and convenient storage and transportation.
Common application fields
Due to its excellent performance and environmental friendliness, hot-melt pressure-sensitive adhesives are widely used:
Packaging industry: Carton sealing tape (the most common brown sealing tape we see), self-sealing strips for express bags.
Label industry: Self-adhesive labels (labels attached to plastic bottles and glass bottles).
Hygiene products: Release paper and fixing tape on the back of diapers and sanitary napkins.
Medical field: Medical breathable tape, electrode sheets.
Automobile interior: Fixation of some interior parts.
Electronics industry: Some electronic components that need to be temporarily fixed.
