Oil major advantage of co-extruded composite bag

?

The main advantage of oil is co-extruded composite bag, no drilling agent and solvents, without the need for any physical and chemical treatment on the substrate surface, producing a small amount of labor without having to remove the binder after drying the solvent, save complex process in many processes. The following points merit some oil paper said co-extruded composite technology:

(1) In the multi-layer co-extruded film, the pigment can be added in a layer of resin, the color of the composite film was prepared with.

(2) to facilitate the addition of an appropriate filler in a layer of the material, giving a composite film having a desired slip properties, antistatic properties and anti-UV.

(3) to facilitate the selection of each layer of the excellent performance of the resin to obtain a composite film overall performance, but simply changed the order of arrangement of the layers of material, or changing the thickness of a layer of material will be made each performance different composite materials.

Pinhole rate (4) co-extruded composite material is almost zero.

(5) to facilitate the rational design structure materials, in order to achieve the best technical performance and economic effect. More expensive material can be reduced its thickness, reduce production costs.
