Description

A kind of light weight high-barrier scratch resistant color paper plastic-aluminum milk powder packaging composite construction
Technical field
The utility model relates to milk powder packing technique field, particularly relates to a kind of light weight high-barrier scratch resistant color paper plastic-aluminum milk powder packaging composite construction.
Background technology
At present domestic and international milk powder packaging market is mainly packed and carton package form based on iron flask.Iron flask packaging quality weight, use inconvenience, and cost is high, and ink is printed directly on iron flask, there is hidden danger to food quality.Although carton package meets the requirement of low-carbon (LC), environmental protection, packaging structure is firm not, and crushing resistance, water proofing property are poor.
Commodity in the modern life, not only need to use some new materials to pack, and more to give prominence to performance attractive in appearance, but in the market, colored ink in the external packing of food to be printed on film or directly printing on the wrapper, its shortcoming is not scratch-resistant, easily fades in turn-up process or transportation, and ink can move out, do not meet the quality requirement of present food.
In color film, print is generally combined with each other bi-material with solventless adhesive with packaging material complex machining process, and baby milk powder etc. have high-quality food, harsh for quality requirement, does not meet new material packing instructions.On the other hand, if be wrapped on packaging material after being heated by color printing shrink film, owing to shrinking shaping rear pattern, font, position stretching very greatly, affect appearance.
Utility model content
The utility model provides a kind of light weight high-barrier scratch resistant color paper plastic-aluminum milk powder to pack composite construction, has that quality is light, the feature of compact conformation.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of light weight high-barrier scratch resistant color paper plastic-aluminum milk powder to pack composite construction, comprise seven-layer structure, be followed successively by from skin to internal layer: color printing thin layer, the first tack coat, ply of board, the second tack coat, aluminium foil layer, the 3rd tack coat and hot sealing layer.
Described color printing thin layer is pet film, bidirectional stretching polypropylene film, polyester aluminizer or nylon film, and described color printing thin layer inner face uses colored ink printing, has white ink layer in colored ink surface coverage.
Described colored ink is gravure printing ink, and described white ink is acrylic compounds or polyurethanes curing agent.
Described first tack coat is made up of polyethylene or PE modified polymer.
The weight of described ply of board is 300g/m 2~ 420g/m 2.
Described second tack coat is take polyethylene as the adhesion resin of base material.
The thickness range of described aluminium foil layer is 7 μm ~ 12 μm.
Described 3rd tack coat is take polyethylene as the adhesion resin of base material.
Described hot sealing layer is metallocene PE resin.
Beneficial effect
Owing to have employed above-mentioned technical scheme, the utility model compared with prior art, there is following advantage and good effect: the utility model adopts the film with good print performance as cladding material, strong and the low migration of printing-ink of appearance looks elegant, third dimension, scratch-resistant, meet the quality requirement of present food, and adopt food grade materials to make itself and cardboard compound, one-shot forming, reduce costs, avoid simultaneously color film and paper in conjunction with during film because causing pattern position to occur deviation by thermal processing distortion.The utility model quality is light, and compact conformation, can compare favourably with the barrier property of iron flask packaging material and compressive property, have a good application prospect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
