Abstract
The invention discloses a multi-layer co-extruded high-barrier impermeable pesticide packaging film, and relates to a compounded packaging film. The packaging film is formed by co-extruding seven film layers and compounding, wherein the seven film layers are a polypropylene (PP) layer, a TL layer, a polyamide (PA) layer, an ethylene-vinyl alcohol (EVOH) layer, a PA layer, a TL layer and a Pemet layer from outside to inside respectively. The invention has the advantages that: the high-barrier pesticide packaging film is produced and developed by a multi-layer co-extrusion technology according to different properties of various high polymer materials, has the barrier property of metal, overcomes the defect that the metal is easily corroded by acid, alkali, sulfur and the like, has the transparency of glass, overcomes the defect that the glass is easy to break, has the portability of paper, overcomes the defect that the paper is easy to wet and damage, and has the functions of various plastic films.
Description
Technical field
The present invention relates to compound packaging film, specifically is the impermeable pesticides packaging film of a kind of multi-layer co-extruded high-barrier.
Background technology
At present, characteristics such as agricultural chemicals ubiquity concentration height, severe toxicity, very harmful to human body.Thereby the security of pesticides packaging is very important.After agricultural chemicals used, the remains of pesticide environmental pollution problem that its packing material brought also can not be ignored.The agricultural chemicals 2/3rds that China produces is liquid formulation.And for a long time, the liquor agricultural chemicals adopts glass bottle packaging always., vial exists breakage rate height, glass bottle inner plug to seal tight and shortcoming such as metering inconvenience, and therefore " to mould for glass " become the irreversible trend of pesticides packaging.
Summary of the invention
It is a kind of safe and effective that technical problem solved by the invention is to provide, the convenient impermeable pesticides packaging film of multi-layer co-extruded high-barrier that uses.
Technical problem solved by the invention realizes by the following technical solutions:
The impermeable pesticides packaging film of a kind of multi-layer co-extruded high-barrier is composited after by co-extrusion by seven layer films, and it is characterized in that: described seven layer films are respectively PP layer, TL layer, PA layer, evoh layer, PA layer, TL layer and Pemet layer from outside to inside.
The thickness of described every layer film is respectively PP layer 18-22 micron, TL layer 4-6 micron, PA layer 8-12 micron, evoh layer 4-6 micron, PA layer 8-12 micron, TL layer 4-6 micron, Pemet layer 14-16 micron.
Described PP layer is the polypropylene material bed of material.
Described TL layer is the binder resin material layer.
Described PA layer is the polyamide material layer.
Described evoh layer is ethene and ethenol copolymer material layer.
Described Pemet layer is the metallocene linear-low density polyethylene material layer.
With the film that described each material constitutes, after order stack from outside to inside, make the high-isolation film that includes 7 layer film layers by co-extrusion machine.
Beneficial effect of the present invention utilizes various macromolecular material different performances to take multi-layer co-extruded technology, produces and has developed high-barrier pesticides packaging film, and it not only has the barrier of metal, has remedied metal again and has been subject to the deficiency that acid, alkali, sulphur etc. corrode; The transparency of existing glass eliminated the shortcoming of Glass breadks easily again, and the portability of existing paper has overcome the make moist weakness of rapid wear of paper again; And possesses the function of various plastic sheetings.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment one, and the impermeable pesticides packaging film of a kind of multi-layer co-extruded high-barrier is distinguished PP layer, TL layer, PA layer, evoh layer, PA layer, TL layer and Pemet layer from outside to inside, is composited by co-extrusion machine after stack.
Wherein the thickness of every layer film is respectively 20 microns of the PP polypropylene material bed of materials, 5 microns of TL binder resin material layers, 10 microns on PA polyamide material layer, EVOH ethene and 5 microns of ethenol copolymer material layers, 10 microns on PA polyamide material layer, 5 microns of TL binder resin material layers, 15 microns of Pemet metallocene linear-low density polyethylene material layers, and the thickness of the compound high-isolation film that obtains after the co-extrusion is 70 microns.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
