Abstract
The utility model relates to packing bag for foods and provides a three-layer composite packing bag. The three-layer composite packing bag is provided with an orientation polypropylene layer and is characterized in that a polyethylene glycol terephthalate layer and a curtain coating polypropylene film layer are composited outside the orientation polypropylene layer in sequence. The three-layer composite packing bag solves the problems that a traditional food packing bag is prone to air leakage and pressure difference in the plateau region can easily cause explosion of the packing bag, and the like. The three-layer composite packing bag can be widely applied to packing bags for retaining freshness of the foods.
Description
The (1) technical field: the utility model relates to the packaging bag of food, especially a kind of three-layer composite packaging bag.
(2) background technology: at present; Food pack generally only has the oriented polypropylene (OPP) layer, promptly adopts oriented polypropylene (OPP) to process bag film, the packaging bag poor sealing of processing like this; In the local time of being transported to the plateau; The local pressure differential in plateau usually causes packaging bag gas leakage or blows, and makes food often rotten, has brought enormous economic loss.
The (3) summary of the invention: the purpose of the utility model is exactly will solve the easy gas leakage of traditional food pack and in the place, plateau problems such as pressure differential causes that packaging bag is blown easily arranged, and a kind of three-layer composite packaging bag is provided.
The concrete scheme of the utility model is: improve to traditional food pack, it has the oriented polypropylene (OPP) layer, it is characterized in that: said oriented polypropylene (OPP) layer outside is compounded with PETG layer and cast polypropylene film layer successively.
The thickness sum of the layer of oriented polypropylene (OPP) described in the utility model, PETG layer and cast polypropylene film layer is 0.1mm.
The utility model has added PETG layer and cast polypropylene film layer on common oriented polypropylene (OPP) layer, good airproof performance not only, and make packaging bag arrive the place, plateau also can not blow, guarantee the shipping mass of food effectively.
The (4) description of drawings:
Fig. 1 is the front view of the utility model;
Fig. 2 is the A-A view of Fig. 1.
Among the figure: 1-oriented polypropylene (OPP) layer, 2-PETG layer, 3-cast polypropylene film layer.
The (5) specific embodiment:
Referring to Fig. 1 and Fig. 2; The utlity model has oriented polypropylene (OPP) layer (being also referred to as the OPP layer) 1; Particularly: said oriented polypropylene (OPP) layer 1 outside is compounded with PETG layer (being also referred to as pet layer) 2 and cast polypropylene film layer (being also referred to as the CPP layer) 3 successively; Wherein, the thickness sum of oriented polypropylene (OPP) layer 1, PETG layer 2 and cast polypropylene film layer 3 is 0.1mm, has promptly constituted the utility model.
Claims (2)
1. a three-layer composite packaging bag has the oriented polypropylene (OPP) layer, it is characterized in that: said oriented polypropylene (OPP) layer outside is compounded with PETG layer and cast polypropylene film layer successively.
2. a kind of three-layer composite packaging bag according to claim 1 is characterized in that: the thickness sum of said oriented polypropylene (OPP) layer, PETG layer and cast polypropylene film layer is 0.1mm.
