Xingtai Witt Plastics Launches PVDC Multilayer Co-Extrusion High Barrier Blown Film

PVDC multi-layer co-extruded high-barrier blown film is a new type of packaging material with high barrier MA-PVDC as barrier layer. By utilizing the characteristics of co-extrusion, it can organically combine MA-PVDC, PE, EVA, PP, PA and other materials. Get up and achieve complementary functions. Xingtai Weide Plastics Co., Ltd. can produce high-barrier films with oxygen permeability <1cd/~rf·0.1Mpa·d and vapor permeability <0.5g/nf·d according to user requirements. This film can replace aluminum plastic composite film, EVOH co-extruded film, nylon co-extruded composite film.

At present, the company's main push is MA-PVDC co-extruded transparent substrate and black and white milk film (asymmetric structure). Its application is very extensive, such as cooked meat, dairy products, cold meat, seafood, fruit juice, jelly, fruit canned soft, tea, medicine; toothpaste, cosmetics, food, oily and puffed food, metal rust.

It is said that the content of PVDC in this co-extruded film is about 10%, and the packaging bag can be recycled for injection molding.

Compared with coating PVDC, it has higher barrier performance, no residual solvent, no cracking layer. Compared with PVDC multilayer cast film, it has better vertical and horizontal strength. Compared with PVDC dry film, there is more high barrier property. Compared with coextruded films of EVOH, PVA, and PA, there is better gas barrier performance, and the barrier property to oxygen is not changed due to moisture. Compared with aluminum-plastic composite film, it has no pinholes, no break cracks, and transparency.
