Abstract
The utility model relates to a high obstructive composite liquid packing film, which comprises a basic layer, a core layer and an outer layer, the basic layer is a high intensity PE layer,, an aluminum layer is arranged on the basic layer to form the core layer, a composite body of the core layer and the basic layer is combined with the outer layer with a casting PE layer, the outer layer is a PE layer; the utility model can effectively obstruct the permeation of oxygen and ultraviolet, and prolong the preservation period of internally preserved substances; the decorative effect of the aluminum layer can make the packing more aesthetic, the material is environment-friendly and easy to be recycled.
Description
(1) technical field
The utility model relates to a kind of compound packaging film, relates in particular to a kind of composite fluid packaging film of high-barrier.
(2) background technology
The material that the present common liq packaging film that uses mainly adopts is the blend monofilm of linear low density polyethylene (LLDPE) and hp-ldpe (LDPE).Though easy to process, with low cost, material environment friendly, but because the polyethylene kind film is bad to the barrier property of light, gas, the liquid substance of internal memory is easily oxidized and be subjected to ultraviolet irradiation etc. and influence the quality of this material, and as nutrition taste color and luster etc., the shelf-life is shorter.
For extending the shelf life, on a lot of packagings the material of high-barrier.High barrier material is defined as: 20 ℃, 65% humidity, 24 hours every cubic meter oxygen transit doses are lower than the material of 10 cm3s.What meet this requirement has inorganic material such as glass, tin-plate, aluminium and ethylene-vinyl alcohol copolymer (EVOH), polyvinylidene chloride minority High molecular materials such as (PVDC).
Chinese patent CN2464668Y (application number 01213482.1) discloses a kind of " high-barrier milk preservation composite packing film ", adopting three-decker, is that the heat sealability black and white film material of 30-60um, the barrier material that is 12-40um as the interlayer and the thickness of bonding agent constitute by thickness.Though have stronger barrier property, its barrier material that adopts all has certain defective, except that cost higher and table seal technology be subjected to easily water, acid, friction etc. cause fade, polypropylene film (BOPP) belongs to the big plastic sheeting of oxygen permeability; The PET polyester film is to the breach sensitivity, and tear strength is low; PA nylon membrane hygroscopic property is big, moisture-vapor transmission height, heat-sealing temperature height.
Chinese patent CN2505282Y (application number 01257780.4) discloses a kind of paper composites of aluminizing, can be used for liquid food, pharmaceutical packing, form by ply of paper and compound aluminium coated, though this packing just have preservation and effect preferably, but its cost is very high, can also needs expensive Special Equipment, and at present domesticly also can't reclaim, and is unfavorable for environmental protection.
(3) summary of the invention
The purpose of this utility model provides a kind of composite fluid packaging film of high-barrier, solve the deficiency of above-mentioned existing packing, good barrier property is promptly arranged, can guarantee the quality of content, have the outward appearance of suitable cost, grace again and satisfy environmental protection requirement.
To achieve the above object, the technical solution adopted in the utility model is: high-barrier composite fluid packaging film comprises basic unit, sandwich layer and skin, described basic unit is high-intensity PE layer, the coating upper aluminum layer is a sandwich layer in basic unit, the complex of sandwich layer and basic unit is compound with skin with the PE layer of hydrostomia, and skin is the PE layer.
The skin of described high-barrier composite fluid packaging film is transparent PE layer.
Further, described high-barrier composite fluid packaging film also comprises ink lay between outer PE layer and hydrostomia PE layer, and described ink lay is imprinted on the outer PE layer in being.
The beneficial effects of the utility model are:
1, evenly the vacuum aluminium coated layer of coating makes complex film have barrier preferably, and oxygen permeability, light transmittance and permeable steam rate are all very low, and the permeability of heat of aluminium is good, can reflect 95% radiant heat, alleviates the temperature build-up under the sunlight direct projection.As being used for the packing of liquid milk, the shelf-life can reach three months.And aluminium lamination has strong decorative effect, makes packing more attractive in appearance.
2, seal technology in the employing does not have the worry that fades with the printing ink smell, and transparent PE layer makes mass colour more bright-coloured.
3, adopt solvent-free hydrostomia combination process, heat sealability is good, and binding force is strong, solvent-free smell worry, and the transparency is good, internal stress free, shrinkage percentage is little.The film of MULTILAYER COMPOSITE does not have sand holes, can seepage.
4, the ectonexine material is the same, can adapt to multiple filling apparatus.
5, the cost than high-barrier complex film that adopts EVOH (or PVDC) and paper aluminum composite packing is low, meets economic principle.
6, material environment friendly reclaims easily.
(4) description of drawings
Fig. 1 is high-barrier composite fluid packaging film structure figure described in the utility model.
(5) specific embodiment
Be described further with reference to 1 pair of the utility model of accompanying drawing.Basic unit (1) is high-intensity PE layer, and being coated with aluminium lamination in basic unit (1) is sandwich layer (2), and sandwich layer (2) is compound with outer (5) with the PE layer (3) of hydrostomia with the complex of basic unit (1), and skin described here (5) is transparent PE layer.Also comprise ink lay (4) between outer PE layer (5) and hydrostomia PE layer (3), described ink lay (4) is imprinted on the outer PE layer (5) in being.The production process of this high-barrier liquid packaging film is to go up in basic unit (1) to plate aluminium lamination (2) with vacuum aluminum-coated technology, go up the technology of printing in outer (5) and coat ink lay (4), use the PE layer (3) of solvent-free hydrostomia that they are combined with each other by described structure afterwards again with the lining.
Aluminium coated can blocking oxygen and ultraviolet ray penetrate, prevent the harmful microbe breeding and, reach the effect of guaranteeing the quality, and utilize aluminium lamination gloss the destruction of content nutritional labeling, make picture and text more attractive in appearance.Adopt solvent-free curtain coating technology compound, heat sealability is good, and binding force is strong, solvent-free smell worry, and the transparency is good, internal stress free, shrinkage percentage is little.The seal technology can prevent to fade and the interference of printing ink smell in the employing, and mass colour is also more bright-coloured.This packaging film can be suitable for multiple filling apparatus, and material environment friendly, reclaims easily.
