The moisture-resisting layer is a water/oil blocking layer; the oxygen-preventing layer is a UV (Ultraviolet) light oil layer. In such a mode, the oxygen-preventing moisture-resisting paper is simple in making process, good in use effect and relatively low in cost, the package property of food is greatly improved, food loss is prevented, and the food inside a package box is prevented from contacting with oxygen.
Description
Technical field
The utility model relates to pulp technology for making paper, particularly relates to a kind of paper with the wet function of resistance oxygen resistance.
Background technology
Food loss (scalping) is for describing the term of the net loss of product, the appreciable product quality loss that described loss causes owing to packing.Food loses almost always a kind of negative effect, therefore need to minimize this loss by certain methods.Generally to utilize the function barrier material of sealing to stop food and extraneous contacting.Except food loss, oxygen also can produce harmful effect to the flavour of food, structure, color, nutritional labeling etc., if food directly contacts and can cause more serious spoilage problems with oxygen.In addition, oxygen reaction to a lot of food within the storage life of food itself has a facilitation, as rotting etc. of the oxidation of the variation of microbial growth, color, lipoid and fruit.Therefore, thus the oxygen composition of food in just must protected opposing environment when storing.In reality, food is often sold with single packing, and therefore, the importance of finding the packaging material that relative cost is lower and have a balance an of the best between cost and oxygen resistance is a vital factor for food production and packing.
At present, the PE synthetic paper based article of isolation-type be mostly take CPP, CPE as main body base material synthetic paper by curtain coating or
A kind of film article material that has heat sealability and intend paper that person's blow molding process is produced, for air rail sea route freight
Label, food is as cheese, jelly, packaging bag, the packing of metal objects.Owing to take CPP, CPE as main body base material synthetic paper, the barriering effect of its goods is not good, needs the secondary operations production link of dry-lamination process to increase barrier layer for it.Above-mentioned secondary
Processing not only causes goods to have dissolvent residual phenomenon, and it also produced and can bring environmental pollution, and is detrimental to health,
Its diluent using can not thoroughly be eliminated, and easily causes potential safety hazard etc., and secondly synthetic paper is because it has paper
Characteristic, its rigidity is larger, not soft, has limited the scope of its use.And the wrapping paper for packaging for foodstuff of the prior art is in order to meet moisture barrier property, oxygen resistance, the wrapper surface of being everlasting covers not water-permeable membrane class of PE film or other, although this wrapping paper has met moisture barrier property, oxygen resistance, but all bad to the permeability of ink and absorbability by the film covering thereon, the decorative pattern that cannot be beautifully printed in the above, or the decorative pattern of printing is fuzzy, easily decolouring.
