Abstract
The invention discloses a novel composite thin film material for food safe packaging. Through a seven-layer co-extrusion film blowing technology, the novel composite thin film material with a PE/TIE/PA/TIE/PA/TIE/PE structure is produced and a layer mass ratio of PE/TIE/PA/TIE/PA/TIE/PE is 2: 1: 1.5: 1: 1.5: 1: 2. The novel composite thin film material is free of glue bonding, does not contain volatile solvents, does not produce residue, reduces damage to an operator and satisfies food safe packaging requirements.
Description
technical field
The present invention relates to a kind of polymeric material field, particularly a kind of novel composite film material for food security packaging.
Background technology
Current, the plastic sheeting for packaging for foodstuff is not often a certain single material, and is usually all the composite film material of two or more combination of materials, to meet the different demand of packaging for foodstuff.Traditional composite membrane is bonded together by N-1 road glue by N kind (N >=2) plastic sheeting, as PA film and PE film are bonded together, and the requirement sealed with satisfied resistance oxygen and bag.But the glue that conventional composite film uses in producing has solvent volatilization and remains, and the solvent of volatilization can cause body harm to operator, and dissolvent residual can pollute food.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of novel composite film material for food security packaging.
Technical scheme of the present invention is:
A kind of novel composite film material for food security packaging, adopt seven-layer co-extrusion film-blowing process, produce the composite film material for food security packaging that structure is PE/ TIE/PA/TIE/PA/ TIE/PE, its interlayer quality proportioning is PE:TIE:PA:TIE:PA:TIE:PE=2:1:1.5:1:1.5:1:2.
The NEW TYPE OF COMPOSITE membrane material of production of the present invention, without the need to glue bonding, there is not solvent volatilization and residual phenomena, thus minimizing is to the harm of operator and the requirement meeting food security packaging.
detailed description of the invention:
A kind of novel composite film material for food security packaging, adopt seven-layer co-extrusion film-blowing process, produce the composite film material for food security packaging that structure is PE/ TIE/PA/TIE/PA/ TIE/PE, its interlayer quality proportioning is PE:TIE:PA:TIE:PA:TIE:PE=2:1:1.5:1:1.5:1:2.
By PA resin, PE resin, TIE resin fusion plastification in different extruders respectively, resin after melting is clamp-oned in same die head, be evenly distributed in die head by certain interlayer structure, then obtain through inflation, cooling and shaping, rolling the composite film material packed for food security.
Claims (2)
1. the novel composite film material for food security packaging, is characterized in that: adopt seven-layer co-extrusion film-blowing process, and structure is the composite film material for food security packaging of PE/ TIE/PA/TIE/PA/ TIE/PE.
2. a kind of novel composite film material for food security packaging according to claim 1, is characterized in that: structure is the interlayer quality proportioning of the thin-film material of PE/ TIE/PA/TIE/PA/ TIE/PE is PE/ TIE/PA/TIE/PA/ TIE/PE=2:1:1.5:1:1.5:1:2.
