Description
Technical field
The present invention relates to a kind of composite package film, especially a kind of corrosion-resistant catsup composite package film, belongs to the technical field of packaging material.
Background technology
At present, on catsup packaging market, packaged form is of a great variety at home, is mainly divided into iron flask packing and plastic bag packaging.The iron flask solanum sauce shelf-life is longer, but packing cost is relatively very high.Because plastic bag packaging cost performance is very high, therefore plastic bag packaging is a trend of catsup Packaging Development, but because catsup presents acidity, pH value is in 4 left and right, the packaging bag of plastic bag packaging generation in the market layering broken bag phenomenon is a lot, has brought very large restriction to the fast development of plastic bag packaging.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of corrosion-resistant catsup composite package film is provided, its compact conformation, corrosion-resistant, cost is low, safe and reliable.
According to technical scheme provided by the invention, described corrosion-resistant catsup composite package film, comprise polyethylene film, on described polyethylene film, bonding is provided with two biaxially oriented polyester films that rush, described two biaxially oriented polyester film that rushes is provided with the high aluminium foil layer that extends, the described high bonding of extending on aluminium foil layer is provided with without benzene without ketone inner-printing ink layer, describedly without benzene, without ketone inner-printing ink layer, is provided with biaxially oriented polyester film.
Described two biaxially oriented polyester film that rushes is arranged on polyethylene film by the 3rd polyurethane adhesive water layer bonding, the high aluminium foil layer that extends is bonded in two punching on biaxially oriented polyester film by the second polyurethane adhesive water layer, without benzene, without ketone inner-printing ink layer, by the first polyurethane adhesive water layer, is bonded in high extension on aluminium foil layer.
The thickness of described biaxially oriented polyester film is 12 μ m, and the high thickness that extends aluminium foil layer is 7 ~ 9 μ m, without benzene, without the thickness of ketone inner-printing ink layer, is 1 ~ 2 μ m, and two thickness that rushes biaxially oriented polyester film is 15 μ m, and the thickness of polyethylene film is 50 ~ 80 μ m.
The thickness of the thickness of the thickness of described the first polyurethane adhesive water layer, the second polyurethane adhesive water layer and the 3rd polyurethane adhesive water layer is 3 ~ 5 μ m.
Advantage of the present invention: by printing without benzene without ketone inner-printing ink layer on biaxially oriented polyester film, and then extend aluminium foil layer and twoly rush biaxially oriented polyester film and polyethylene film is composited by adhesive with height, by using the first polyurethane adhesive water layer, the second polyurethane adhesive water layer and the 3rd polyurethane adhesive water layer, prevent from causing composite membrane lamination due to the acidity of catsup, thereby greatly improve the compound fastness of film.Owing to using aluminium foil material, the barrier property of composite membrane is fine in addition, can complete shading, and also moisture-vapor transmission is at 0.1g/m
2below 24h0.1Mpa, OTR oxygen transmission rate is at 0.1cm
3/ m
2below 24h0.1Mpa, thereby reach not only cost-saving but also can meet shelf-life requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Description of reference numerals: 1-biaxially oriented polyester film, 2-rush biaxially oriented polyester film, 7-the 3rd polyurethane adhesive water layer and 8-polyethylene films without benzene without ketone inner-printing ink layer, 3-the first polyurethane adhesive water layer, the high extension of 4-aluminium foil layer, 5-the second polyurethane adhesive water layer, 6-couple.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1: in order to adapt to the packing instructions of catsup, the present invention includes polyethylene film 8, on described polyethylene film 8, bonding is provided with two biaxially oriented polyester films 6 that rush, described two biaxially oriented polyester film 6 that rushes is provided with the high aluminium foil layer 4 that extends, the described high bonding of extending on aluminium foil layer 4 is provided with without benzene without ketone inner-printing ink layer 2, describedly without benzene, without ketone inner-printing ink layer 2, is provided with biaxially oriented polyester film 1.
Particularly, described two biaxially oriented polyester film 6 that rushes is arranged on polyethylene film 8 by the 3rd polyurethane adhesive water layer 7 bondings, the high aluminium foil layer 4 that extends is bonded in two punching on biaxially oriented polyester film 6 by the second polyurethane adhesive water layer 5, without benzene, without ketone inner-printing ink layer 2, by the first polyurethane adhesive water layer 3, is bonded in high extension on aluminium foil layer 4.The 3rd polyurethane adhesive water layer 7 rushes between biaxially oriented polyester film 6 and polyethylene film layer 8 two, the second polyurethane adhesive water layer 5 extends aluminium foil layer 4 and two punching between biaxially oriented polyester film 6 at height, the first polyurethane adhesive water layer 3 is extending between aluminium foil layer 4 without ketone inner-printing ink layer 2 and height without benzene, and biaxially oriented polyester film 1 is positioned at without benzene without on ketone inner-printing ink layer 2.Without benzene, without ketone inner-printing ink layer 2, be printed on biaxially oriented polyester film 1.
In the embodiment of the present invention, biaxially oriented polyester film 1 and two biaxially oriented polyester film 6 that rushes all adopt the polyester film that reaches production in the gold of Jiangyin, without benzene, without ketone inner-printing ink layer 2, adopt the Central Asia, Suzhou UMT99, the first polyurethane adhesive water layer 3 adopts Henkel 2781, the high aluminium foil layer 4 that extends adopts the height of Dare to extend aluminium foil, and the high percentage elongation that extends aluminium foil layer 4 is greater than 1%; The second polyurethane adhesive water layer 5 adopts Henkel 2781, the three polyurethane adhesive water layers 7 to adopt Henkel 3640, and polyethylene film 8 adopts the product of Jiangyin Wan Run.
