Abstract
The invention discloses a novel PE film which is formed by coextrusion of three layerswhich are respectively an outer layer, a middle layer and an inner layer; thickness ratio among the outer layer, the middle layer and the inner layer is 1 plus/minus 0.3 : 1 plus/minus 0.3 : 1 plus/minus 0.3; raw materials of the outer layer are low-density polythene and linear low-density polythene with weight ratio of 1 : 1 to 1 : 8; raw materials of the middle layer are polypropylene and metallocene linear low-density polythene with weight ratio of 1 : 0.2 to 1 : 10; and raw materials of the inner layer are the linear low-density polythene, the metallocene linear low-density polythene and anti-block agent with weight ratio of 100 : 100 : 2to 100 : 10 : 1. The novel PE film has the advantages that modification is carried out on the middle layer by the polypropylene, the film has favorable heat sealing performance by adding the metallocene linear low-density polythene into the middle layer and the inner layer to cause molecules of the PE film after the modification to interlink to form a space stereo formation, and the molecule density is increased, thereby the purpose of preventing oil molecules from permeating is achieved, and the PE film is enabled to have favorable oil separation function.
Description
Technical field
The present invention relates to a kind of PE film.
Background technology
The PE film is generally by skin, middle level and internal layer are three-layer co-extruded to form, because the PE film has softness, transparent and good heat sealability, therefore the PE film has obtained using widely on the composite food package bag, but in use, its strand of common PE film is linear condition, density is low, oil molecule sees through the PE film easily and is penetrated into another side from the one side of film, cause its oil removal poor performance, be easy to cause edible oil to be penetrated into the problem of packaging bag outer surface if be used to pack the food (as instant noodles oil bag) of oiliness, it is attractive in appearance to influence product on the one hand, reduces consumer's desire to buy; Owing to the infiltration of oil, shortened the shelf-life of food on the other hand.
Summary of the invention
The purpose of this invention is to provide a kind of Novel PE film with good oil removal performance.
Technical scheme of the present invention is such: a kind of Novel PE film, by outer, middle level with internal layer is three-layer co-extruded forms; Thickness ratio between three layers of above-mentioned skin, middle level and the internal layers is 1 ± 0.3:1 ± 0.3:1 ± 0.3; Above-mentioned outer field raw material is that weight ratio is low density polyethylene (LDPE) (LDPE) and the LLDPE (LLDPE) of 1:1-1:8, the raw material in above-mentioned middle level is that weight ratio is polypropylene (PP) and the metallocene linear-low density polyethylene (M-LLDPE) of 1:0.2-1:10, and the raw material of above-mentioned internal layer is that weight ratio is LLDPE (LLDPE), metallocene linear-low density polyethylene (M-LLDPE) and the opening agent of 100:100:2-100:10:1.
After adopting such scheme, the beneficial effect of Novel PE film of the present invention is: (PP) carries out modification to the middle level by polypropylene, by making film have better heat sealability in middle level and internal layer interpolation metallocene linear-low density polyethylene (M-LLDPE), make the PE divided thin film subchain after the modification become the space multistory configuration, increased molecular density, thereby reach the purpose that prevents the oil molecule infiltration, make PE film of the present invention have good oil removal function.
