Abstract
The invention discloses a low-temperature heat-sealing plastic film. Through a seven-layer co-extrusion film blowing technology, the low-temperature heat-sealing plastic film with a PE/TIE/PE/PA/TIE/PE/PE structure is produced and a layer mass ratio of PE/TIE/PE/PA/TIE/PE/PE is 2: 1: 1: 2: 1: 1: 2. The low-temperature heat-sealing plastic film can be used in automatic food loading, realizes sealing of a packaging bag at a temperature of 60-80 DEG C, and prevents taste change caused by exposure of foods at a high temperature.
Description
Technical field
The present invention relates to a kind of polymeric material field, particularly a kind of low-temperature heat-sealing plastic sheeting.
Background technology
Along with the development of packing technique, increasing food all starts to use on-line automatic filling, carries out the shaping of packaging bag and sealing in pouring process.This canning means improves the efficiency of packaging for foodstuff effectively, but has also derived corresponding problem simultaneously.As the auto-filling of some sapor meat food, often need the sealing carrying out packaging bag under the high temperature of 180 DEG C-230 DEG C after filling, so high temperature often has influence on the mouthfeel of sapor meat food itself, reduces quality.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of low-temperature heat-sealing plastic sheeting.
Technical scheme of the present invention is:
A kind of low-temperature heat-sealing plastic sheeting, adopt seven-layer co-extrusion film-blowing process, produce the low-temperature heat-sealing plastic sheeting that structure is PE/ TIE/PE/PA/TIE/ PE/PE, its interlayer quality proportioning is PE:TIE:PE:PA:TIE:PE:PE=2:1:1:2:1:1:2.
The low-temperature heat-sealing plastic sheeting of production of the present invention, this kind of thin-film material is applied on the auto-filling of food, can seal low at the temperature of 60 DEG C-80 DEG C to packaging bag, food can not be made to expose at high temperature, cause the change of mouthfeel.
detailed description of the invention:
A kind of low-temperature heat-sealing plastic sheeting, adopt seven-layer co-extrusion film-blowing process, produce the low-temperature heat-sealing plastic sheeting that structure is PE/ TIE/PE/PA/TIE/ PE/PE, its interlayer quality proportioning is PE:TIE:PE:PA:TIE:PE:PE=2:1:1:2:1:1:2.
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 low-temperature heat-sealing plastic sheeting through inflation, cooling and shaping, rolling.
Claims (2)
1. a low-temperature heat-sealing plastic sheeting, is characterized in that: adopt seven-layer co-extrusion film-blowing process, produce the low-temperature heat-sealing plastic sheeting that structure is PE/ TIE/PE/PA/TIE/ PE/PE.
2. a kind of low-temperature heat-sealing plastic sheeting according to claim 1, it is characterized in that: structure is the low-temperature heat-sealing plastic sheeting of PE/ TIE/PE/PA/TIE/ PE/PE, its interlayer quality proportioning is PE:TIE:PE:PA:TIE:PE:PE=2:1:1:2:1:1:2.
