Abstract
The invention relates to a packaging film, and in particular relates to a seven-layer co-extrusion asymmetrical NE (Neoprene) nylon film, belonging to the field of packaging materials. The seven-layer co-extrusion asymmetrical NE nylon film comprises seven layers, wherein the first layer is an NE nylon layer; the second layer is an adhesive layer; the third layer is a paper layer; the fourth layer is an NE nylon layer; the fifth layer is an adhesive layer; the sixth layer is a PVDC (Polyvinyl Dichloride) coated layer; and the seventh layer is an NE nylon layer. The seven-layer co-extrusion asymmetrical NE nylon film disclosed by the invention is in the mode of multi-layer co-extrusion and has strong waterproofness and air permeability and good practicability; and in addition, due to addition of an inorganic compound component, the seven-layer co-extrusion asymmetrical NE nylon film is low in environment pollution and can be recycled.
Description
Technical fieldThe present invention relates to a kind of packaging film, specifically relate to the asymmetric NE nylon membrane of a kind of seven-layer co-extrusion, belong to the packaging material field.
Background technologyAlong with the progress of science and technology, the kind of packaging film emerges in an endless stream.Nylon membrane is widely used in the every field such as weaving, printing, chemical industry, and its water proofing property, poisture-penetrability are come out top always, but in the relatively unification of other performances.For example, the single thin film of many routines, barrier is poor, as reaching packing instructions, needs could realize through a plurality of single thin film combinations, can't satisfy user's high standard requirement; In addition, in addition, owing to mostly adopt polymer, environment there is certain pollution in the nylon membrane composition of the prior art, can not recycles, do not have environmental protection
Effect.
Summary of the inventionDefective in view of above-mentioned technology exists the invention provides the asymmetric NE nylon membrane of a kind of seven-layer co-extrusion.
To achieve these goals, technical scheme of the present invention is: the asymmetric NE nylon membrane of seven-layer co-extrusion is divided into seven layers; Ground floor: NE nylon layer, the second layer: adhesive-layer, the 3rd layer: ply of paper, the 4th layer: NE nylon layer, layer 5: adhesive-layer, layer 6: PVDC coating layer, the 9th layer: the NE nylon layer.
Described nylon layer is added with inorganic compound particles, and particle diameter is that 10mm-25 μ m nylon layer thickness is 12 μ-18 μ.
The content of described inorganic compound particles is 1-20%.
The percentage elongation of described nylon membrane is between 100%-300%.
Described inorganic compound particles is silicon compound.
Compared with prior art, beneficial effect of the present invention is: this nylon membrane adopts multi-layer co-extruded pattern, and water proofing property is strong, good permeability, has good practicality, the interpolation of inorganic compound composition makes this nylon membrane environmental pollution little, and can recycle.
The specific embodiment
The present invention is further described below in conjunction with specific embodiment.
The asymmetric NE nylon membrane of seven-layer co-extrusion is divided into seven layers; Ground floor: NE nylon layer, the second layer: adhesive-layer, the 3rd layer: ply of paper, the 4th layer: NE nylon layer, layer 5: adhesive-layer, layer 6: PVDC coating layer, the 9th layer: the NE nylon layer.
Described nylon layer is added with inorganic compound particles, and particle diameter is that 10mm-25 μ m nylon layer thickness is 12 μ-18 μ.
The content of described inorganic compound particles is 1-20%.
The percentage elongation of described nylon membrane is between 100%-300%.
Described inorganic compound particles is silicon compound.
