Abstract
A reinforced and easily degradable composite paper-plastic film for package is composed of coated layers, paper layers, adhesive layers and degradable central film layer.
Description
The present invention relates to a kind of stratiform packaging material, specifically a kind of reinforced and easily degradable composite paper-plastic film for package.
The disclosed Chinese patent 1055506A in 1991 (application number is 90105802.5) has introduced a kind of three-layer plastic compound film, but this composite membrane is difficult for degraded under field conditions (factors), is unfavorable for environmental protection.
The objective of the invention is to design a kind of reinforced and easily degradable composite paper-plastic film for package at above-mentioned deficiency.
Technical scheme of the present invention is: it is a layer structure, and this layer structure contains outer and the degradable plastic bed of material, and skin is made up of coating, paper layer and adhesive phase successively, is adhesive phase between paper layer and the degradable plastic layer, and coating is positioned at outer field surface.
Therefore the present invention helps environmental protection owing to easily decompose under field conditions (factors).In addition, the present invention also has higher oxygen barrier and moisture resistance.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a layer structure schematic diagram of the present invention.
Fig. 3 is the layer structure schematic diagram of another embodiment of the present invention.
The invention will be further described below in conjunction with drawings and Examples.
As depicted in figs. 1 and 2, the present invention is a layer structure, (1`) two layers of skins (1) are arranged, the degradable plastic bed of material (2) one deck, outer (1) (1`) successively by coating (3) (3`), paper layer (4) (4`) and adhesive phase (5) (5`) form, the used material of the degradable plastic bed of material (2) is a polyvinyl alcohol.The arrangement of above-mentioned described layer structure is followed successively by coating (3), paper layer (4), adhesive phase (5), the degradable plastic bed of material (2), adhesive phase (5`), paper layer (4`), coating (3`).
The used material of the degradable plastic bed of material of the present invention (2) also can be poly-methyl glutamate, or polyethylene glycol, or cornstarch and polyolefin blends, or polyolefin and phosphatization catalytic materials blend, or big right fiber and powder alkyl polyester blend.
Paper layer of the present invention (4) (4`) used material is a natural fiber paper, the main component of natural fiber paper is a string, adhesive phase (5) is used material natural glue (5`), the main component of natural glue is a natural macromolecular material, and coating (3) (3`) used material is a grease.
Paper layer of the present invention (4) is (4`) used also can be synthetic fibre paper, the main component of synthetic fibre paper is synthetic fibers, adhesive phase (5) (5`) used material also can be a composite adhesives, the main component of composite adhesives is a synthesized polymer material, and coating (3) (3`) used material also can be a resin.
As shown in Figure 3, the present invention also can have only one deck skin (1), and its layer structure is coating (3), paper layer (4), adhesive phase (5), the degradable plastic bed of material (2) successively.
