Now there are basically two ways of carton packaging, one is to use hot melt glue machine to seal the box, the other is to use 0PP tape to seal the box or cold glue to seal the box. Hot melt glue machine sealing is a new bonding method, more and more More and more production companies are adopting this method. Hot melt adhesive machine sealing can be divided into automatic, semi-automatic or manual hot melt adhesive machine sealing, which has more advantages than traditional tape sealing.

Advantages of hot melt adhesive machine sealing:

1. The packaging is of good quality and environmentally friendly. The hot-melt glue machine is used to seal the box with hot-melt adhesive, which has strong viscosity. The carton is not easy to deform and crack during transportation, and can well maintain the packaging shape and viscosity of the carton. The hot melt adhesive used in hot melt adhesive box sealing is a green, environmentally friendly and renewable industrial adhesive that does not contain formazan. It is non-polluting and odorless, and meets environmental protection standards. It is widely used in the packaging industry for sticking boxes, and it also improves the product quality. aesthetics.

2. The cartons packed by the thermal glue machine are resistant to high temperature and low temperature. In the environment of minus 20 degrees or more than 90 degrees, the carton will not appear to be unglued or degummed. The adhesive tape is not good, and the adhesive tape is easy to unglue and degumming in the cold northern climate, which brings great inconvenience to the packaging of the product.

3. The sealing cost of the hot-melt adhesive machine is low, and the efficiency is high. The automatic hot-melt adhesive machine can seal the box within 1-3 seconds, which is suitable for mass production. There is no need to stop feeding during the use of the hot melt adhesive machine, but the tape needs to be stopped for replacement.

4. Hot-melt adhesive machine-sealed cartons also provide good anti-helmet function. Since the adhesive penetrates into the corrugated paper, any attempt to open the carton will tear the fibers between the cartons. Once opened, it cannot be restored, eliminating counterfeit products. The adhesive tape can be cut with a knife, and the contents can be removed unconsciously and sealed again.

Hot melt glue and hot melt glue machine have been used in the carton packaging industry for decades, and now the hot melt glue machine can automatically complete the glue spraying work, and there is no limit to the box and box.
