Abstract
The invention belongs to the technical field of packaging materials and particularly relates to a film additive. The coating-free directly combined film additive is characterized in that the film additive is prepared by ethylene-vinyl acetate copolymer (EVA), paraffin, hydrogenation resin, metallocene polyethylene, antioxidant and light stabilizer, and the mass percentages of the components are as follows: 75 percent of ethylene-vinyl acetate copolymer (EVA), 2 percent of paraffin, 15 percent of hydrogenation resin, 7 percent of metallocene polyethylene, 0.5 percent of antioxidant and 0.5 percent of light stabilizer. The coating-free directly combined film additive can be applied to a coating-free directly combined film and has the characteristic of good adhesion property.
Description
Technical field
The invention belongs to field of packaging material, be specifically related to a kind of additive of film.
Background technology
Present pre-coating film (or claiming coating-free directly combined film), it forms (as shown in Figure 1) by subfunction layer 1, sandwich layer 2, coating functional layer 3, and sandwich layer 2 is between subfunction layer 1 and coating functional layer 3; The material of subfunction layer 1 is mainly polypropylene (PP), and the material of sandwich layer 2 is modified poly ethylene (PE), and the material of coating functional layer 3 is caking agent (as the modified EVA caking agent), and 3 heat seals of coating functional layer are on sandwich layer 2.Subfunction layer 1 is with sandwich layer 2 heat seals.
Adopt on the sandwich layer and scribble the coating functional layer in advance, during use, coating-free directly combined film directly will be coated with functional layer and contact thermal synthesis one (and coating viscosity glue) again with wrapping paper or plastics, use simply, make things convenient for.
Summary of the invention
The object of the present invention is to provide the good coating-free directly combined film additive of a kind of adhesiveproperties.
To achieve these goals, technical scheme of the present invention is: coating-free directly combined film additive, it is characterized in that: it is prepared from by ethene-vinyl acetate vinegar multipolymer (EVA), paraffin wax, hydrogenation resin, metallocene PE, antioxidant and photostabilizer, and the shared mass percent of each component is: ethene-vinyl acetate vinegar multipolymer (EVA) 75%, paraffin wax 2%, hydrogenation resin 15%, metallocene PE 7%, antioxidant 0.5%, photostabilizer 0.5%.
The invention has the beneficial effects as follows: be applied in the coating-free directly combined film, have the good characteristics of adhesiveproperties.
Description of drawings
Fig. 1 is the film structural representation of (or claim coating-free directly combined film) of pre existing;
Among the figure: 1-subfunction layer, the 2-sandwich layer, 3-is coated with functional layer.
Embodiment
Embodiment 1:
Coating-free directly combined film additive, it is prepared from by ethene-vinyl acetate vinegar multipolymer (EVA), paraffin wax, hydrogenation resin, metallocene PE, antioxidant and photostabilizer, and the shared mass percent of each component is: ethene-vinyl acetate vinegar multipolymer (EVA) 75%, paraffin wax 2%, hydrogenation resin 15%, metallocene PE 7%, antioxidant 0.5%, photostabilizer 0.5%.
Described antioxidant is 1010 antioxidants (producing as the bright ease chemical in Changzhou company limited).
Described photostabilizer is benzotriazole light stabilizer (existing benzotriazole light stabilizer all is applicable to the present invention).
Preparation method of the present invention is: the raw material of apolegamy is mixed, be processed into powdery (extrusion temperature is 180-230 ℃) by forcing machine, get coating-free directly combined film additive.
Coating-free directly combined film additive is added in the subfunction layer of coating-free directly combined film, the addition of coating-free directly combined film additive accounts for 20% of subfunction layer quality.The coating-free directly combined film that is added with coating-free directly combined film additive of the present invention is refuted from experiment: refute from the coating-free directly combined film that is added with coating-free directly combined film additive of the present invention with the heat-sealing tensiometer, refute in the time of 85 ℃ from pulling force 〉=6.5 newton.Under the similarity condition, and existing polypropylene heat-sealing film is refuted from experiment, refutes from pulling force≤0.5 newton.The adhesiveproperties that the coating-free directly combined film that is added with coating-free directly combined film additive of the present invention is described is good.
Embodiment 2:
Substantially the same manner as Example 1, difference is: described antioxidant is 1076 antioxidants (for currently available products).
The present invention cited each raw material (comprising different molecular weight, different manufacturers) can both be realized the present invention, does not enumerate embodiment one by one at this.
Claims (3)
1. coating-free directly combined film additive, it is characterized in that: it is prepared from by ethene-vinyl acetate vinegar multipolymer, paraffin wax, hydrogenation resin, metallocene PE, antioxidant and photostabilizer, and the shared mass percent of each component is: ethene-vinyl acetate vinegar multipolymer 75%, paraffin wax 2%, hydrogenation resin 15%, metallocene PE 7%, antioxidant 0.5%, photostabilizer 0.5%.
2. coating-free directly combined film additive according to claim 1 is characterized in that: described antioxidant is 1010 antioxidants or 1076 antioxidants.
3. coating-free directly combined film additive according to claim 1 is characterized in that: described photostabilizer is a benzotriazole light stabilizer.
