Technical Field
The utility model relates to a soft packaging material technical field, concretely relates to chinese chestnut wrapping bag.
Background
At present, Chinese chestnut packaging bags are all made of small-capacity high-barrier bags serving as inner packages, a plurality of inner packaging bags are packaged into outer packaging bags for transportation and sale, the outer packaging bags are of the conventional Chinese chestnut packaging bag structure, but in the packaging and transportation process, the inner packages can be extruded to the outer packages, so that the inner packages have obvious puncture marks on the outer packages, and the appearance of products is not attractive.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a more soft chinese chestnut wrapping bag is felt to the not enough among the prior art to the matter.
The purpose of the utility model is realized through the following technical scheme:
the Chinese chestnut packaging bag is provided, the Chinese chestnut packaging bag is sequentially laminated from outside to inside and only comprises a biaxially oriented polypropylene film layer and a linear low-density polyethylene film layer, the biaxially oriented polypropylene film layer and the linear low-density polyethylene film layer are bonded through a Jade 888 adhesive layer, an aluminum coating layer is further arranged on the surface of the linear low-density polyethylene film layer, the thickness range of the biaxially oriented polypropylene film layer is 17-21 mu m, the thickness range of the linear low-density polyethylene film layer is 66-74 mu m, and the thickness range of the aluminum coating layer is 0.03-0.06 mu m.
Wherein the thickness of the biaxially oriented polypropylene film layer is 18 μm.
Wherein the linear low density polyethylene film layer has a thickness of 70 μm.
Wherein the thickness of the aluminum-plated layer is 0.04 μm.
The utility model has the advantages that: the utility model discloses a Chinese chestnut wrapping bag is provided with the layer of aluminizing and is located linear low density polyethylene film layer, makes linear low density polyethylene film layer become the thin layer of taking the separation nature to make the feel of holistic Chinese chestnut wrapping bag softer, the collision thorn trace mark of inner packing (Chinese chestnut wrapping bag) to the external packing is relatively unobvious, and the Chinese chestnut wrapping bag has certain separation nature, has preliminary guard action to the inner packing, keeps more apparent effect to product appearance;
the biaxially oriented polypropylene film layer and the linear low-density polyethylene film layer are compounded through the Jade stand 888 adhesive layer, the compounding of the utility model can be completed only by one-time operation, the compounding production efficiency is increased by 50 percent compared with the prior structure, the compounding efficiency is improved, and the production cost is reduced; the jade 888 adhesive layer which is more suitable for the aluminum coating is adopted for dry compounding, the biaxially oriented polypropylene film layer and the linear low-density polyethylene film layer are bonded together, the flexibility of the jade 888 adhesive layer is better, the biaxially oriented polypropylene film layer and the linear low-density polyethylene film layer are compounded without obvious damage to the aluminum coating, the fastness of the aluminum coating is kept good, and therefore the effects of good strength and good overall performance between the two material composite layers are achieved.
