Usually we see compound is coated with glue laminating machine, such as the use of solvent adhesive is to water glue and hot melt adhesive, etc) on the membrane material in advance to hot pressing, without glue draping material film is not the same.Such as PE and kraft paper compound is to be strong for PE film side to do special processing, and then use without glue type composite machine to PE material melt composite in brown paper.This without glue coated withstand rubbing and still not easy to blister, resistant to high temperature of 120 ℃.
The advantages of this technology is very obvious, because there is no glue so greatly reduce the cost, but also in the process of production is not easy to volatilize harmful gas to ensure safety and penetration, no plastic cladding materials membrane technology is the innovation of the PE membrane technology in the market now.
