U.S. has developed a packaging film containing a moisture barrier

A U.S. company has developed a multi-layer film containing a moisture barrier layer. This new product can be widely used in the packaging of food and pharmaceutical products.

According to reports, this package with a moisture-proof layer with Topascos as the inner layer, and the outer polypropylene at the same time, compared with PVDC polymer multi-layer film performance, with a stronger moisture barrier and transparency. As the material does not contain ethylene, halogens and plasticizers, its safety and environmental advantages are significant. At the same time, the production process of the film is a multi-layer simultaneous pressing process. Compared with the laminated film, there is less chance of contamination during production, and the processing process is also easy to grasp. As for the new inner material, Topascos, is a member of the amorphous engineering plastics group. This material is transparent, strong, moisture-proof, strong and stable. It has been approved by the US FDA, and it is agreed that this material can be used directly in various applications. Food contact packaging. This kind of film is divided into three grades according to the different inner layers. Each kind of film has different colors: transparent, white and amber. (Liu Gong)
