Abstract
Provided is a high isolation compound packaging film including a base material layer, a printing layer, an isolation layer, a protective layer and a heat-sealing layer, the printing layer, the isolation layer, the protective layer and the heat-sealing layer are successively covered on the base material layer, the printing layer and the isolation layer, the isolation layer and the protective layer, the protective layer and the heat-sealing layer are bonded by bonding layers. By adopting the above structure, the film in the utility model has the advantages of high isolation property, high mechanical performance, low cost, good heat-sealing property, poison and smell-free, being free of the adsorption of micro particles due to no static electricity can be generated while the heat-seal layer directly contacts with products, the film can effectively overcome the problems that the packaging film in the prior art is easy to be torn because of less intensity and is easy to loose because of low isolation property, moreover, the film in the utility model is particularly suitable for the vacuum packaging with the needs of high isolation and intensity.
Description
Technical field
The utility model relates to a kind of improvement of packaging film, particularly a kind of high-barrier composite package film.
Background technology
At present, packaging film on the market is selected for use be the plastic composite packaging film with the material of aluminizing as barrier material, its product structure is that two layers or more is compound, such cost of product is lower, but for requiring high-barrier and high strength, being used to vacuumize the packaging film of packing, above-mentioned material is difficult to reach requirement, easily in packaging process because of the not high enough broken bag of strength of material, or deposit with sales process in because of the strong inadequately bale breaking of barrier.
Summary of the invention
The purpose of this utility model will provide a kind of high-barrier composite package film exactly, its can actv. overcome existing packaging film insufficient strength and broken bag, because of the barrier problem of strong bale breaking inadequately, be particularly suitable for the packing requirements that requires high-barrier and high strength, is used to vacuumize packing.
The purpose of this utility model is achieved in that a kind of high-barrier composite package film; comprise substrate layer 1, printed layers 2, barrier layer 3, protective cover 4 and hot sealing layer 5; on substrate layer 1, be coated with printed layers 2, barrier layer 3, protective cover 4 and hot sealing layer 5 successively, between printed layers 2 and the barrier layer 3, between barrier layer 3 and the protective cover 4 and bonding between protective cover 4 and the hot sealing layer 5 by bonding coat 6.
Substrate layer 1 is selected biaxial stretching polyester (BOPET) film for use; The material of barrier layer 3 is an aluminium foil; The material of protective cover 4 is biaxial tension nylon (BOPA) film; Hot sealing layer 5 selects for use tasteless non-poisonous food stage not have the polyethylene of static (PE) film; The material of bonding coat 6 is a polyurethane adhesive.
Because the material of the utility model substrate layer is biaxial stretching polyester (BOPET) film,, also ink lay literal and pattern there is good protective action simultaneously so its superior chemical resistance and the high grade of transparency can guarantee the quality of printing effect; Again because the material of barrier layer is an aluminium foil, so its excellent barrier makes packing possess performances such as moistureproof, airtight, shading and withstanding corrosion; Again because the material of protective cover is biaxial tension nylon (BOPA) film, so utilize its excellent mechanical property, make the mechanical characteristics and the anti-puncture ability of packing increase greatly, effectively prevent to be packaged in the automatic packaging process and fill broken bag or distortion because of high-low pressure vacuumizes; Hot sealing layer adopts tasteless non-poisonous food stage not have the polyethylene of static (PE) film, its good heat sealing ability has guaranteed the heat seal strength of packing material after the moulding, simultaneously can prevent that finely ground particles from sticking to heat seal place, destroy heat seal place PE layer structure closely, eliminate the hidden danger of bad gas leakage that causes of heat seal and broken bag.All adopt the dry type composite methods bonding between the layers of material, can improve the binding force between the layers of material, prevent layering by polyurethane adhesive.
Description of drawings
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Fig. 1 double as Figure of abstract.
Among the figure: 1, substrate layer, 2, printed layers, 3, barrier layer, 4, protective cover, 5, hot sealing layer, 6, bonding coat.
The specific embodiment
As shown in Figure 1; a kind of high-barrier composite package film; comprise substrate layer 1, printed layers 2, barrier layer 3, protective cover 4 and hot sealing layer 5; on substrate layer 1, be coated with printed layers 2, barrier layer 3, protective cover 4 and hot sealing layer 5 successively, between printed layers 2 and the barrier layer 3, between barrier layer 3 and the protective cover 4 and bonding between protective cover 4 and the hot sealing layer 5 by bonding coat 6.
On substrate layer 1, be coated with printed layers 2, barrier layer 3, protective cover 4 and hot sealing layer 5 successively, bonding between the layers of material by polyurethane adhesive bonding coat 6.The utility model gross thickness is 0.07～0.2mm.
Wherein, the used thickness of substrate layer 1 biaxial stretching polyester (BOPET) film is 0.012mm;
The thickness of printed layers 2 and bonding coat 6 can be ignored;
The used thickness of barrier layer 3 aluminium foils is 0.007mm;
The thickness that protective cover 4 biaxial tension nylon (BOPA) films are selected for use is 0.015mm;
The thickness that hot sealing layer 5 polyethylenes (PE) film is selected for use is 0.075mm.
Gross thickness is about 0.110mm.General high activity dried yeast powder vacuumizes the material that the packaging film bag adopts this thickness.Simultaneously,, can adjust by the thickness that changes each layer material, to the difference that the mechanical characteristics of packing material requires according to product or client to reach product or requirement of client.
The utility model has the advantages that high barrier, high-mechanical property, cost is low, does not have static with hot sealing layer that product directly contacts and can prevent finely ground particles absorption, and the heat sealing performance is good and nonpoisonous and tasteless.
Claims (1)
