The utility model has the advantages that:

1. The utility model provides a novel high separation wrapping bag, through setting up the outmost of the bag body into high density polyethylene film layer, high density polyethylene's hardness is good with drawing high strength, can the bearing, consequently sets up and can play effectual protection to the bag body at the surface of the bag body, and then plays effectual protection to food in the packing transportation.

2. The utility model provides a novel high separation wrapping bag, through with the innermost of the bag body set up to low polyethylene film layer, low polyethylene's texture is soft, has good freshness protection, consequently sets up and can carry out effectual storage at the internal surface of the bag body to food.

3. The utility model provides a novel high separation wrapping bag, through being provided with PVA coating high barrier film and PVDC resin film at the middle part of the bag body, PVA coating high barrier film is coated the PVA that has added nano inorganic matter and is printed, compound after the polyethylene film, its oxygen blocking rate is less than 2cm3/(m2 24h 0.1MPa), the effectual quality requirement of being wrapped in the thing to aseptic package that has guaranteed, PVDC (polyvinylidene chloride) has good low permeability, barrier property and chemical resistance, PVDC uses in multiple substrate such as PE, PP, PVC, Polyamide (PA), polyethylene glycol terephthalate (PET) etc., use biaxial stretching polypropylene film as an example, the oxygen permeability reduces 1000 times after the coating, the water permeability reduces 3 times, the coating can be single-layer or multilayer, general individual layer coating can possess good separation effect for 2.5 mu m, therefore, the two films are arranged in the middle of the bag body, and the high-barrier effect can be effectively realized.

4. The utility model provides a novel high separation wrapping bag is provided with the sealing strip through crimping heat-seal department all around at two bag bodys, can further sealed fixed by sealing strip to two bag bodys of crimping heat-seal department, and the wrapping bag receives pressure in the transportation and produces when deforming, can improve the stability that the bag body is sealed all around by sealing strip, and then has improved the sealed packing effect of wrapping bag.
