Abstract
The invention discloses a novel film for making a buffer gas column bag. Through a seven-layer co-extrusion film blowing technology, the novel film with a PE-PE-TIE-PA-TIE-PP-PP structure is produced and a layer mass ratio of PE-PE-TIE-PA-TIE-PP-PP is 2: 1: 1.5: 1: 1.5: 1: 2. The buffer gas column bag prepared from the novel film has excellent buffer protection performances, can be recycled and does not cause environment pollution.
Description
Technical field
The present invention relates to a kind of polymeric material field, particularly a kind of novel thin film for making buffering air column bag.
Background technology
Buffering air column bag is a kind of buffering package of novel environment friendly.Traditional buffering package known by us is as frothing foam, corrugated paper, EPE etc., and not only buffering effect protected effect is not good, and as foam etc. after a procedure, can not recycling, be one of main white pollution.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of novel thin film for making buffering air column bag.
Technical scheme of the present invention is:
A kind of novel thin film for making buffering air column bag, adopt seven-layer co-extrusion film-blowing process, produce the novel thin film for making buffering air column bag that structure is PE-PE-TIE-PA-TIE-PP-PP, its interlayer quality proportioning is PE:PE:TIE:PA:TIE:PP:PP=2:1:1.5:1:1.5:1:2.
A kind of novel thin film for making buffering air column bag of production of the present invention, utilizes buffering air column bag prepared by this kind of thin-film material, not only has very excellent buffer protection performance, can also be recovered in utilization, can not to environment.
detailed description of the invention:
A kind of novel thin film for making buffering air column bag, adopt seven-layer co-extrusion film-blowing process, produce the novel thin film for making buffering air column bag that structure is PE-PE-TIE-PA-TIE-PP-PP, its interlayer quality proportioning is PE:PE:TIE:PA:TIE:PP:PP=2:1:1.5:1:1.5:1:2.
By PA resin, PP resin, TIE resin, PE resin fusion plastification in different extruders respectively, resin after melting is clamp-oned in same die head, being evenly distributed in die head by certain interlayer structure, then obtaining a kind of novel thin film for making buffering air column bag through inflation, cooling and shaping, rolling.
Claims (2)
1. for making a novel thin film for buffering air column bag, it is characterized in that: adopt seven-layer co-extrusion film-blowing process, producing the novel thin film for making buffering air column bag that structure is PE-PE-TIE-PA-TIE-PP-PP.
2. a kind of novel thin film for making buffering air column bag according to claim 1, it is characterized in that: structure is the novel thin film for making buffering air column bag of PE-PE-TIE-PA-TIE-PP-PP, and its interlayer quality proportioning is PE:PE:TIE:PA:TIE:PP:PP=2:1:1.5:1:1.5:1:2.
