Abstract
The present invention relates to a biaxial tension heat-sealing type extinction membrane used for foods packing and a production method, wherein, a basement membrane of the extinction membrane is provided with an upper surface layer, a middle core layer and a lower surface layer which are packed into a whole through heat melt and jostling together. The upper surface layer is an extinction layer and the lower surface layer is a heat-sealing layer. The production method is mainly that the lower surface of the extinction has the heat-sealing performance by changing the materials that the lower surface uses, and the extinction collects the heat-sealing performance and extinction performance as a whole. Taking the basement membrane as food packing membrane is able to simplify the processing procedure of back procedure, reduce the cost in the backward position production process, decrease the pollution to environments, and simultaneously high heat-sealing intensity and fancy flat gloss pictures are provided.
Description
Technical field:
The present invention relates to a kind of packaging for foodstuff industry with matt film and manufacture method thereof, but concrete be a kind of biaxial tension and the matt film and the manufacture method thereof that can directly seal.
Background technology:
Matt film is the film that uses the delustring masterbatch to make through biaxial tension on single top layer, the basement membrane of general-duty normal dull film is three layers in the market, the wherein upper and lower two-layer delustring layer that is, interlayer is a sandwich layer, these three layers become one by hot melt, co-extrusion again, this kind matt film does not have heat sealability, in the packaging for foodstuff production process, at first need to carry out compound with cast polypropylene film (CPP) or polyethylene (PE) film, increased work programme and cost in the production process of downstream, the lining cement of compound usefulness can produce pollution to environment simultaneously.
Summary of the invention:
But technical matters to be solved by this invention provides a kind of biaxial tension of using and has the matt film and the manufacture method thereof of heat sealability in the packaging for foodstuff industry.
For achieving the above object, bidirectional stretching heat-sealing extinction film used for package of the present invention, the basement membrane of this matt film is divided into upper epidermis, intermediate core layer, following top layer, upper epidermis, sandwich layer, following top layer become one by hot melt, co-extrusion again, wherein upper epidermis is the delustring layer, and following top layer is a hot sealing layer.
The thickness of preferred hot sealing layer and delustring layer is respectively the 10-15% of basement membrane thickness.
The manufacture method of bidirectional stretching heat-sealing extinction film used for package of the present invention is:
Mix is even respectively at first will to produce the used raw and auxiliary material of hot sealing layer, sandwich layer, the delustring layer of basement membrane, and wherein hot sealing layer, sandwich layer, used its component of raw and auxiliary material of delustring layer are respectively as following weight percent:
Hot sealing layer: heat-sealing masterbatch 95-98%
Antiseize agent 2-4%
Sandwich layer: homo-polypropylene 96-98%
Antistatic additive 2-4%
Delustring layer: delustring masterbatch 100%
Mix send into respectively after evenly separately melt extrude machine and auxiliary extruder becomes melt through fusion plastification, melt passes through runner, through three layers of die head, casting sheet device, co-extrusion becomes substrate, and substrate is drawn into film through the biaxial orientation stretching machine vertical and horizontal, and the thickness of control film reaches the requirement of regulation, film is carried out corona treatment, film after corona treatment is rolled into big film volume through up-coiler, and big film rolls into the timeliness frame and carries out ageing treatment, cuts into the basement membrane finished product through dividing then.
Described heat-sealing masterbatch is an ethylene-propylene copolymer; Antiseize agent is the functional master batch that contains the synthetic silica composition.
The degree of isotacticity of described homo-polypropylene is 96%, and fusion index is 2.8-3.2 g/10min; Antistatic additive is for containing composite polymer amine antistatic master batch.
Described delustring masterbatch is the ethylene-propylene copolymers that contains the @ vinyl.
Technique effect of the present invention is: bidirectional stretching heat-sealing type matt film integrates heat sealability and extinction, the postorder manufacturing procedure is simplified, reduced the cost in the production process of downstream, minimizing is to the pollution of environment, do food package film with this basement membrane, have very high heat seal strength and exquisite honed pattern; It is rational in infrastructure in addition, stretch processes production efficiency height, and productive costs is low.
The specific embodiment:
The invention will be further described below by embodiment.
Embodiment one: hot sealing layer, sandwich layer, the used raw and auxiliary material of delustring layer are as following weight percent:
Hot sealing layer: heat-sealing masterbatch 98%
Antiseize agent 2%
