Description

A kind of antistatic film
Technical field
The present invention relates to packing technique field, is specially a kind of antistatic film.
Background technology
Polyethylene is main using one of raw material in plastics package membrane material, with the development of plastic package material, is gathered The dosage of ethene is also increasing, but since polythene material is non-polar molecular structure, the strand that its covalent bond is formed, both Cannot ionize, it is also difficult to transmit free electron, once because friction make electronics lose and it is powered after if be difficult eliminate, be also also easy to produce quiet Electricity, easily adsorbs the dust granule in air or brings infringement in itself to packaged product, so as to influence to pack membrane material Be processed further, seriously affected application of the membrane material in terms of packaging, therefore often add antistatic additive in process of production To eliminate the electrostatic effect of polyethylene film, the comprehensive performance of film is set to reach preferable effect, but the above-mentioned membrane material prepared Material, only with antistatic property, and is short of barrier, is so easy to make packaged product make moist and damage or become Matter, so as to influence service life or shelf-life.
The content of the invention
In view of the above-mentioned problems, the present invention provides a kind of antistatic film, it has both preferable antistatic property and barrier, While avoiding the dust granule in material absorption air, and prevent from causing damage to packaged product in itself, it can also prevent Only make moist, ensure that service life, extend the shelf-life.
Its technical solution is such：A kind of antistatic film, it is lamination layer structure, it is characterised in that from top to bottom according to Secondary is hot sealing layer, filled layer, the first adhesive layer, barrier layer, the second adhesive layer, outer layer, and each layer accounts for the weight percent of film gross weight Number is respectively 15-30%, 7-40%, 10-15%, 10-15%, 5-10%, 10-15%；The hot sealing layer includes anti-static polyethylene Resin, the barrier layer are nylon or ethylene-vinyl alcohol copolymer.
It is further characterized by：
The thickness of the antistatic film is 25 μm -250 μm；
Linear low density polyethylene, low density polyethylene (LDPE), metallocene low density polyethylene (LDPE) and auxiliary agent are also selected in the hot sealing layer Any of or several mixtures；
The nylon of the barrier layer selects any one or several mixtures of homopolymerization nylon, salad nylon and copolymer nylon；
The filled layer selects linear low density polyethylene, any one or several mixtures of low density polyethylene (LDPE)；
The outer layer is nylon layer or polyethylene layer；The nylon layer of the outer layer is the homopolymerization that mass ratio is 1 ~ 3: 1 ~ 3: 1 ~ 2 The mixture of nylon, salad nylon and copolymer nylon, the polyethylene layer are the linear low density polyethylene that mass ratio is 2 ~ 4: 1 The mixture of alkene, low density polyethylene (LDPE)；
First adhesive layer, the second adhesive layer are the mixed of the linear low density polyethylene that mass ratio is 2 ~ 4: 1 and adhesive Compound；
The density range of linear low density polyethylene is 0.918g/cm3~0.935g/cm3, the density range of low density polyethylene (LDPE) It is 0.920g/cm3~0.950g/cm3, the density range of metallocene low density polyethylene (LDPE) is 0.918g/cm3~0.942g/ cm3。
The beneficial effect of the present invention is the lamination layer structure of antistatic film, is followed successively by hot sealing layer, filling from top to bottom The percetage by weight that layer, the first adhesive layer, barrier layer, the second adhesive layer, outer layer, and each layer account for film gross weight be respectively 15-30%, 7-40%、10-15%、10-15%、5-10%、10-15%；Contain anti-static polyethylene resin in hot sealing layer, barrier layer for nylon or It is ethylene-vinyl alcohol copolymer, passes through the antistatic property of anti-static polyethylene resin, nylon or ethylene-vinyl alcohol copolymer Barrier so that the antistatic film produced can effectively avoid the dust granule in material absorption air, and prevent pair While packaged product causes damage in itself, it can also prevent from making moist, ensure that service life, extend the shelf-life, into one Step expands application of the membrane material in terms of packaging.
