Abstract
It the utility model is related to flexible packing material technical field, more particularly to a kind of novel high-barrier plastic packaging bag, sealed and formed by two sides composite membrane, include pet film, pet film and the polyethylene film of plating silica coating successively per face composite membrane ecto-entad, pet film, pet film and the polyethylene film of the plating silica coating pass sequentially through adhesive bonding.The novel high-barrier plastic packaging bag made of above-mentioned thin-film material, have concurrently it is good block water, the advantages of oxygen resistance and production cost are low.
Description
Technical field
It the utility model is related to flexible packing material technical field, and in particular to a kind of novel high-barrier plastic packaging bag.
Background technology
As shown in Figure 1, existing barrier plastic packaging bag 5 is by pet film 1, ethenol copolymer
Film 2 and polyethylene film 3 are combined by adhesive, have the function of good water proof, oxygen barrier, wherein ethenol copolymer
Film 2 has gas significant iris action, and in packaging structure, fragrance and quality are improved by preventing the infiltration of oxygen
Reserving degree.There is hydroxyl in the molecular structure of vinyl alcohol copolymer resin, therefore ethenol copolymer film 2 has parent
Water-based and hygroscopicity.
There are the problem of be：After ethenol copolymer 2 adsorbed moisture of film, the barrier property of gas can be affected,
2 purchase cost of ethenol copolymer film is higher at the same time, procurement cycle length.
Utility model content
The purpose of this utility model is that being directed to deficiency of the prior art, and provide a kind of novel high-barrier plastics package
Bag, have concurrently it is good block water, the advantages of oxygen resistance and production cost are low.
To achieve the above object, the technical solution that the utility model is taken is：A kind of novel high-barrier plastic packaging bag, by
Two sides composite membrane seals to be formed, and includes the polyethylene terephthalate of plating silica coating successively per face composite membrane ecto-entad
Ester film, pet film and polyethylene film, the poly terephthalic acid second of the plating silica coating
Terephthalate films, pet film and polyethylene film pass sequentially through adhesive bonding.
Wherein, the adhesive is polyurethane.
Wherein, the thickness of the pet film of the plating silica coating is 10-15 μm.
Wherein, the thickness of the pet film is 10-15 μm.
Wherein, the thickness of the polyethylene film is 50-70 μm.
Preferably, the thickness of the pet film of the plating silica coating is 13 μm.
Preferably, the thickness of the pet film is 12 μm.
Preferably, the thickness of the polyethylene film is 60 μm.
Wherein, the heat seal strength of the two sides composite membrane is more than 30N/15mm.That is the polyethylene film in a face composite membrane
It is more than 30N/15mm with the heat seal strength of the polyethylene film in another side composite membrane.
Wherein, the heat seal strength of the two sides composite membrane is 60-80N/15mm.
The beneficial effects of the utility model：
A kind of novel high-barrier plastic packaging bag of the utility model, is sealed by two sides composite membrane and is formed, per face composite membrane
The ethenol copolymer film in existing packaging structure is replaced with the pet film of plating silica coating,
Pet film base material deflection is good, and water and steam coats one layer of plating silica coating through small in addition,
Oxygen, block-water performance raising are hindered, although the barrier of ethenol copolymer film is more excellent, its cost is higher, the new plating of this reality
The barrier property of the pet film of silica coating can meet existing packaging for foodstuff to the shelf-life
It is required that while in purchase cost have more advantage.
Brief description of the drawings
Fig. 1 is the structure diagram of existing barrier plastic packaging bag.
Fig. 2 is the structure diagram of the composite membrane of the new novel high-barrier plastic packaging bag of this reality.
Reference numeral：
1- pet films, 2- ethenol copolymers film, 3- polyethylene films, 4- plating silica
The existing barrier plastic packaging bag of pet film, 5-, the 6- composite membranes of coating.
Embodiment
The utility model is further described with the following Examples.
Fig. 1 is the structure diagram of existing barrier plastic packaging bag, no longer right herein since background technology had been described in detail
Fig. 1 is repeated.
As shown in Fig. 2, the new novel high-barrier plastic packaging bag of this reality, is sealed by two sides composite membrane 6 and is formed, per face composite membrane
6 ecto-entads include pet film 4, the polyethylene terephthalate of plating silica coating successively
Film 1 and polyethylene film 3, the pet film 4 of the plating silica coating, poly terephthalic acid second
Terephthalate films 1 and polyethylene film 3 pass sequentially through adhesive bonding.In the present embodiment, adhesive is polyurethane, of low cost
And bond effect is good.
By the pet film 4 of plating silica coating, 1 and of pet film
The composite membrane 6 that polyethylene film 3 forms, existing skill is substituted with the pet film 4 of plating silica coating
Ethenol copolymer film 2 in art, thus have concurrently it is good block water, the advantages of oxygen resistance and production cost are low.
Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality
With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general
Lead to it will be appreciated by the skilled person that can be to the technical solution of the utility model technical scheme is modified or replaced equivalently, without departing from this
The spirit and scope of utility model technical solution.
