Abstract
The utility model discloses a double -faced corona composite membrane, this double -faced corona composite membrane including the stack altogether crowded and the last corona layer that goes out, go up the antistatic backing, go up release coatings, sandwich layer, release coatings, antistatic backing and lower corona layer down, go up the higher authority that release coatings and release coatings symmetry down located the sandwich layer below and, go up above the antistatic backing locates release coatings, below release coatings is located down to lower antistatic backing, go up corona layer and corona layer down symmetrical establishing upper and lower two outside of this double -faced corona composite membrane respectively, the technical scheme of the utility model changed current double -faced corona composite membrane's whole thickness, the thickness of the number of piles and each layer has improved the quality that this two -sided corona accords with the membrane, and next sets up two -sided antistatic backing and release coatings, its fine solution current double -faced corona composite membrane have the problem that static is high, solved the high problem of the smooth control degree of difficulty of current double -faced corona composite membrane moreover, antiseized effectual moreover, the life cycle is long.
Description
Technical field
This utility model relates to packaging material, particularly relates to a kind of two-sided corona composite membrane.
Background technology
Thin film is a kind of thin and flexible transparent sheet.Make with plastics, adhesive, rubber or other materials.The thin film made with polrvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, is used for packing, and is used as coating layer.The commercially shared share of plastics package and plastic packet product is increasing, particularly composite plastic flexible package, have been widely used for the fields such as food, medicine, chemical industry, maximum with packaging for foodstuff proportion the most again, such as beverage packaging, quick frozen food packaging, cooking food packaging, fast food packaging etc., these products all bring great convenience to people's life.At present, two-sided corona composite membrane has two-sided corona, and one side can be used for printing, being combined, and another side can be simultaneously used for other operations, but on market, existing two-sided corona composite membrane is usually present the shortcoming that electrostatic control difficulty high, smooth is high.
Utility model content
Problem for above-mentioned existence, this utility model aims to provide a kind of two-sided corona composite membrane, this utility model not only efficiently solves existing two-sided corona composite membrane and there is the problem that electrostatic is high, and solve the problem that existing two-sided corona composite membrane smooth control difficulty is high, anti-adhesion effects is good, uses the cycle long.
To achieve these goals, the technical scheme that this utility model is used is as follows:
A kind of two-sided corona composite membrane, this two-sided corona composite membrane includes superposition co-extrusion and the upper corona layer gone out, upper antistatic backing, upper anti-stick coating, sandwich layer, lower anti-stick coating, lower antistatic backing and lower corona layer；Described upper anti-stick coating and described lower anti-stick coating are symmetrically set in described sandwich layer above and below, described upper antistatic backing is located at above described upper anti-stick coating, described lower antistatic backing is located at below described lower anti-stick coating, and described upper corona layer and described lower corona layer are respectively symmetrically two ragged edges up and down being located at this two-sided corona composite membrane.
Preferably, described upper anti-stick coating and described lower anti-stick coating are smooth oxidant layer, and the thickness of described smooth oxidant layer is 5-10 μm.
Preferably, the material of described upper antistatic backing and described lower antistatic backing is ethoxylated fat race alkylamine, and the thickness of described upper antistatic backing and described lower antistatic backing is 5-10 μm.
Preferably, described upper corona layer and described lower corona layer are made by polyacrylic resin material, and the thickness of described upper corona layer and described lower corona layer is 20-25 μm.
Preferably, described sandwich layer is made up of polyacrylic resin material, and the thickness of described sandwich layer is 40-45 μm.
The beneficial effects of the utility model are: compared with prior art, the technical solution of the utility model changes the integral thickness of existing two-sided corona composite membrane, the number of plies and the thickness of each layer, improve this two-sided corona and meet the quality of film, next arranges two-sided antistatic backing and anti-stick coating, and it well solves existing two-sided corona composite membrane and there is the problem that electrostatic is high, and solves the problem that existing two-sided corona composite membrane smooth control difficulty is high, and anti-adhesion effects is good, use the cycle long.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Wherein: corona layer under antistatic backing, 7-under anti-stick coating, 6-under 1-upper corona layer, the upper antistatic backing of 2-, the upper anti-stick coating of 3-, 4-sandwich layer, 5-.
Detailed description of the invention
In order to make those of ordinary skill in the art be better understood on the technical solution of the utility model, with embodiment, the technical solution of the utility model is further described below in conjunction with the accompanying drawings.
One two-sided corona composite membrane shown in 1 referring to the drawings, this two-sided corona composite membrane includes superposition co-extrusion and the upper corona layer 1, upper antistatic backing 2, upper anti-stick coating 3, sandwich layer 4, lower anti-stick coating 5, lower antistatic backing 6 and the lower corona layer 7 that go out, described sandwich layer 4 is made up of polyacrylic resin material, and the thickness of described sandwich layer 4 is 40-45 μm；Described upper anti-stick coating 3 and described lower anti-stick coating 5 are symmetrically set in described sandwich layer 4 above and below, described upper anti-stick coating 3 and described lower anti-stick coating 5 are smooth oxidant layer, and the thickness of described smooth oxidant layer is 5-10 μm, the smoothness of thin film can be preferably improved by two-sided smooth oxidant layer, antiseize membrane bonds together with product, affects quality；Described upper antistatic backing 2 is located at above described upper anti-stick coating 3, described lower antistatic backing 6 is located at below described lower anti-stick coating 5, the material of described upper antistatic backing 2 and described lower antistatic backing 6 is ethoxylated fat race alkylamine, and the thickness of described upper antistatic backing 2 and described lower antistatic backing 6 is 5-10 μm, preferably resolves existing two-sided corona composite membrane by two-sided upper antistatic backing 2 and lower antistatic backing 6 and there is the problem that electrostatic is high；Described upper corona layer 1 and described lower corona layer 7 are respectively symmetrically two ragged edges up and down being located at this two-sided corona composite membrane, described upper corona layer 1 and described lower corona layer 7 are made by polyacrylic resin material, and the thickness of described upper corona layer 1 and described lower both corona layers 7 is 20-25 μm.
