Barrier Laminated Films (Multilayer Laminated Films)
In most cases, in the cross sections of barrier films, the inner is made up of polyethylene sealing layer, the outer layer is thin and the middle layer of the barrier is of microscopic thickness. It is to be noted that the composition of the barrier material is most important in determining its permeability and not its thickness. Both coextruded processing and dry lamination are available for choice. There are clear films, matte films and metalized films. Our patented technique is to produce the film surface with partially matte or glossy.
Barrier Film Construction
All barrier films are made of multiple layers. The outer layer is a strong plastic with a high melting point, often made of polyester or polypropylene. The inner-middle layer is the barrier material. The bottom layer is a low-density polyethylene, which softens at relatively low temperatures. Additional inner layers are used to increase the barrier properties of the film, and adhesives may be used to cement the layers.
The number of layers, the selection of polymers, the layer configuration and the thickness of individual layers depend on the intended film use, which is customized to order.
Well suited in food packaging where moisture, oxygen and odor barrier is essential. It is ideal for applications such as cheese packaging, sausage chubs, and capliners. Some common examples for barrier films are found in grocery store. Bags used for packaging potato chips and meat products are barrier bags. They can also be laminated to other films and substrates for additional barrier functionality. Barrier films are used to make different packaging products like.
