Laminating soft packaging film and manufacturing method thereof

摘要

The present invention relates to a soft packaging film obtained by laminating two films of a film without using an intermediate material such as PE for bonding or an adhesive and a method of manufacturing the same.;A soft packaging film obtained by bonding any two films of a biaxially oriented polypropylene film, a non-oriented polypropylene film, a polyethylene film, a stretched aluminum evaporated polypropylene film, a non-expanded new aluminum evaporated polypropylene film and an aluminum evaporated polyethylene film;;The bonding interface of the two bonding films is subjected to a corona treatment in a silicone roll while being pressed without delay in the same silicone roll to bond the two films and has no embossing roll or embossing pattern having an embossing pattern successively to the silicone roll for corona treatment and bonding Wherein the bonding film is heated and pressed by an embossing roll to strengthen the bonding strength of the two films.
