Application of Coextruded Film in Various Industries
Author:
There is a kind of film blowing machine for co-extrusion film, which directly blows the film through multi-layer co-extrusion process. The composite film of the co-extrusion film manufacturer is a laminator that uses glue composite process to composite the film.
Coextruded membrane is a microporous membrane or ultrafiltration membrane as a support layer, the surface of only 0.1~0.25 microns thick fine homogeneous membrane as a barrier layer separation membrane. Co-extruded film manufacturers greatly increase the penetration of substances.
The data for the coextruded films includes any possible combination of data. If the coextruded membrane manufacturer covers the ceramic membrane on the metal oxide or the aromatic polyamide membrane on the polysulfone microporous membrane, the flat membrane or roll membrane should be reinforced with non-woven fabric to support the pressure resistance of the microporous membrane, while the hollow fiber membrane does not need the coextrusion composite process, I .e. multiple extruders are used to extrude the material through a special die in the molten state to form a new functional membrane.
The multi-layer and multi-functional composite film produced by the co-extruded film manufacturer can be made in only one processing process, avoiding multiple composite production processes, reducing production energy consumption and data costs, no pollution in the production process, no solvent residue in the finished product, and saving about 30% of the production cost compared with other composite processes. This membrane can be equipped with different components according to the user's requirements to meet different barrier requirements and cost requirements.
wenzhou chuangjia packaging material limited company's main products: seven layer coextrusion stretch film, heat shrinkable film, air valve bag, food packaging multilayer coextrusion vacuum bag, multilayer coextrusion heat shrinkable bag, eleven layer cast film, coextrusion film, stretch film, vacuum food packaging bag, is a stretch film manufacturers.
