Abstract
The utility model discloses a kind of high resistant oxygen high resistant to wet packaging film, it comprises hot sealing layer and skin.Hot sealing layer is formed by the polyethylene particles blowing of modification, its surface is provided with the polyethylene coating of one deck densification, have good oxygen barrier property, the hot sealing layer of modification has good vapor water barriers performance, also improves the mechanical performance of polythene material simultaneously.Skin is made up of PA/PE co-extrusion film, has compared with high tensile and good puncture resistance.The performance that this packing film has high resistant oxygen simultaneously, high resistant wets, has good mechanical strength simultaneously, is applicable to the long-time storage package of some equipment.
Description
Technical field
The utility model belongs to plastics package field, is specifically related to a kind of high resistant oxygen high resistant and wets packaging film.
Background technology
Barrier material conventional at present has aluminium foil, aluminizer, PVDC composite membrane, EVOH co-extrusion film.Aluminium foil and aluminizer have good oxygen and vapor water barriers performance, but this bi-material is opaque, can't see the effect of content and article storage, and the right-angle tearing power of aluminium foil is lower, fold resistant poor performance, and pliability is also inadequate.PVDC composite membrane has certain oxygen-barrier property, and oxygen transit dose is slightly large, and moisture barrier property effect is general.EVOH co-extrusion film moisture barrier property is general, and oxygen barrier property is excellent, along with humidity rising barrier property declines obviously, and on the high side.Above-mentioned material all can not have oxygen barrier simultaneously, hinder moist, transparent and good mechanical strength.
Summary of the invention
The purpose of this utility model is to provide a kind of high resistant oxygen high resistant to wet packaging film, and for transparency high oxygen high resistant wet stock provides a good solution, it has good mechanical performance simultaneously.
The technical solution realizing the utility model object is: the high resistant oxygen high resistant packaging film that wets refers to that oxygen barrier property is less than 1ml/m
224h0.1MPa, vapor water barriers performance is less than 1.5g/m
224h0.1MPa.
A kind of high resistant oxygen high resistant wets packaging film, and comprise hot sealing layer and skin from inside to outside, hot sealing layer arbitrarily one side is provided with coating, and hot sealing layer establishes cated to be cohered by adhesive and skin.
Above-mentioned hot sealing layer is formed by the polyethylene particles blowing through the modification of imvite master batch.
Above-mentioned skin is PA/PE co-extrusion film.
Above-mentioned adhesive is adhesive for polyurethane, Water-soluble adhesive or alcohol dissolubility adhesive.
Above-mentioned coating adopts polyvinyl alcohol.
The utility model compared with prior art, its remarkable advantage: the conjunctive use of (1) imvite master batch and polyethylene coating makes film have superpower oxygen barrier property; (2) filling of imvite master batch is used and is made material have good vapor water barriers performance, and the mechanical strength of material itself is strengthened simultaneously, remains again the transparency of material.
Accompanying drawing explanation
Fig. 1 is that a kind of high resistant oxygen of the utility model high resistant wets the structural representation of packaging film.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Composition graphs 1, a kind of high resistant oxygen high resistant packaging film that wets forms by four layers, comprises hot sealing layer 1 and outer 2 from inside to outside, and hot sealing layer 1 arbitrarily one side is provided with coating, and hot sealing layer 1 establishes cated to be cohered by adhesive and outer 2.Hot sealing layer 1 is formed by the polyethylene particles blowing through the modification of imvite master batch.Specific practice is: imvite master batch and polyvinyl resin are melt extruded jointly granulation and form polyethylene particles, polyethylene particles again blowing obtains hot sealing layer 1.The polyethylene of imvite master batch modification has good vapor water barriers performance and mechanical performance, has heat-sealable.Coating on hot sealing layer 1 is the polyvinyl alcohol of one deck densification, and coating layer thickness about 5 μm, can provide good oxygen barrier property.Outer 4 be PA/PE co-extrusion film, is heat-resistant layer, non-hot sealing layer, has good heat resistance and mechanical property, and outer 4 are bonded by adhesive for polyurethane with the coat side of hot sealing layer 1, and formation high resistant oxygen high resistant wets packaging film.Wherein in polyethylene particles, the adding proportion of imvite master batch is 2-4%.
Embodiment 1
Imvite master batch is added in polyvinyl resin, adding proportion is 2%, jointly melt extrude granulation and form polyethylene particles, polyethylene particles again blowing obtains hot sealing layer 1, and its thickness is 0.08mm, any selection hot sealing layer 1 obtains a face, coating layer of polyethylene alcohol, polyethylene coating thickness is 0.005mm, with polyurethane composite gel by the hot sealing layer 1 of coated polyvinyl alcohol and PA/PE co-extrusion film compound, obtained high resistant oxygen high resistant wets packaging film, and material property is as shown in table 1 below.

The oxygen barrier property of this packaging film is better, is better than the oxygen barrier property of PVDC film and EVOH film, is slightly worse than foil packaging film, and vapor water barriers performance is excellent.
Embodiment 2
Composition graphs 1, in polyvinyl resin, add imvite master batch, adding proportion is 3%, jointly melt extrudes granulation and forms polyethylene particles, polyethylene particles again blowing obtains hot sealing layer 1, film thickness is 0.08mm, selects arbitrarily hot sealing layer 1 to obtain a face, coating layer of polyethylene alcohol, polyethylene coating thickness is 0.005mm, with Water Soluble Compound glue by the hot sealing layer 1 of coated polyvinyl alcohol and PA/PE co-extrusion film compound, obtained high resistant oxygen high resistant wets packaging film, and material property is as shown in table 2 below.
Table 2 high resistant oxygen high resistant wets packaging film 2 performance
The oxygen barrier property of this packaging film is better, is better than the oxygen barrier property of PVDC film and EVOH film, is slightly worse than foil packaging film, and vapor water barriers performance is excellent.
Embodiment 3
Composition graphs 1, in polyvinyl resin, add imvite master batch, adding proportion is 4%, jointly melt extrudes granulation and forms polyethylene particles, polyethylene particles again blowing obtains hot sealing layer 1, its thickness is 0.08mm, selects arbitrarily hot sealing layer 1 to obtain a face, coating layer of polyethylene alcohol, polyethylene coating thickness is 0.005mm, with alcohol-soluble composite rubber alloy by the hot sealing layer 1 of coated polyvinyl alcohol and PA/PE co-extrusion film compound, obtained high resistant oxygen high resistant wets packaging film, and material property is as shown in table 3 below.
Table 3 high resistant oxygen high resistant wets composite film material 3 performance
The oxygen barrier property of this packaging film is better, is better than the oxygen barrier property of PVDC film and EVOH film, is slightly worse than foil packaging film, and vapor water barriers performance is excellent.
