When using hot melt adhesive stick, it should be placed in a cool place to prevent storage and facilitate storage. If it is left for too long, it will stick to the film. I don't think this distinction is because it has been left for too long, not because the film is unusable, but because it can be used. The hot melt glue is soaked in warm water for a period of time, but the temperature of the hot water is not suitable, so that we can alleviate the trouble of strong placement caused by not using it for too long.
The consumption of the hot melt adhesive film is very simple, it can be used as a composite material, and sticky objects can be used as an adhesive for bonding. Observe the temperature and slightly control the temperature. If the temperature is too high, it will affect the application of the hot melt adhesive film and destroy the heat. The melt adhesive film preheating machine, without this method, does not use the temperature of the hot melt adhesive film, so that the hot melt adhesive film is ablated.
