The utility model relates to an aseptic composite packaging bag for packaging food and aims to solve the technical problem that the provided packaging bag has the characteristics that the strength is high; the content resistance is strong; the packaging bag is easy to transport; and resources are effectively saved. The utility model adopts the technical scheme that the liquid aseptic composite packaging bag consists of a bag body and a filling port cover arranged on the bag body in a heat seal mode and is characterized in that the bag body is formed in a mode that an inner film which is made into a bag shape is combined with a composite outer film sleeved outside the inner layer; the composite outer film is formed in a mode that a first blending modified polyethylene layer, a polyethylene glycol terephthalate layer with an aluminized surface and a second blending modified polyethylene layer which are overlapped from outside to inside sequentially are co-extruded and adhered into one whole body; the inner film is formed in a mode that two overlapped third blending modified polyethylene layers are co-extruded and adhered into one whole body or three overlapped third blending modified polyethylene layers are co-extruded and adhered into one whole body; and the first blending modified polyethylene layer is formed in a mode that an outer layer, a middle layer and an inner layer are subjected to blow molding, co-extrusion and overlapping.
Description
Technical field
The utility model relates to a kind of packing appliance, especially the sterile composite package bag of packaging for foodstuff use.
Background technology
In recent years, Chinese agricultural byproducts export share is significantly risen progressively every year, year outlet inspissated juice tons up to a million, and catsup also has about 1,000,000 tons; The employed aseptic packaging of catsup and inspissated juice mostly is the 220L sterile bag of aluminizing and adds a steel drum, adorns the steel drum of 4 220L sterile bags of one ton of product needed and 4 same volumes.The annual assembly packaging of more than 800 ten thousand cover sterile bags and steel drum that needs of this two large outlets kind is together along with agricultural byproducts are exported to abroad.Because through long sea voyage and repeatedly rejecting, fruit juice can not be realized repeated use by the steel drum after having taken, just becoming scrap iron after often only being to use once must melt down again, has caused the wasting of resources and high energy consumption thus; In addition, along with the upheaval of price of steel product, the cost that how to reduce aseptic packaging has become the concern of more and more enterprises.
The utility model content
Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and a kind of liquid sterile composite package bag is provided, this packaging bag should have intensity height, anti-content rerum natura strong, be easy to the characteristics of transporting and effectively economizing on resources.
The utility model provides following technical scheme:
The liquid sterile composite package bag, the can flap on bag is formed by bag and heat-sealing; It is characterized in that described bag is combined with the compound adventitia that is wrapped in the internal layer outside by the inner membrance of system pouch; Described compound adventitia is an one by the first superimposed successively from outside to inside blended and modified polyethylene layer, the PETG layer and the second blended and modified polyethylene layer co-extrusion adhesion aluminized in the surface; Described inner membrance is an one by two stacked the 3rd blended and modified polyethylene layer co-extrusion adhesions of closing, and is one by three stacked the 3rd blended and modified polyethylene layer co-extrusion adhesions of closing perhaps.
The described first blended and modified polyethylene layer is formed by stacking by skin, middle level and internal layer blowing co-extrusion.
The PETG layer of aluminizing in described surface comprises modification PETG layer and the vacuum evaporation inorganic aluminium lamination at modification PETG laminar surface.
The described second blended and modified polyethylene layer is formed by stacking by second skin, second middle level and the second internal layer blowing co-extrusion.
Described the 3rd blended and modified polyethylene layer is formed by stacking by the 3rd skin, the 3rd middle level and the 3rd internal layer blowing co-extrusion.
In the PETG layer of aluminizing in described surface, the one side of aluminizing is back to inner membrance.
The beneficial effects of the utility model are: because packaging material have adopted and extruded composite construction, not only the compound peeling force and the heat seal strength of bag increase substantially, and anti-content rerum natura also significantly improves, prevented that effectively the bag content from being corroded by bacterium, obviously prolonged the resting period of product, alternative existing hard packing container is fit to the depositing of agricultural byproducts after all kinds of deep processings; In addition, also have transportation convenient, the characteristics that economize on resources have broad application prospects.
Description of drawings
Fig. 1 is a right TV structure schematic diagram of the present utility model.
Fig. 2 is the A portion structure for amplifying schematic diagram among Fig. 1.
The specific embodiment
As shown in Figure 1, this liquid sterile composite package bag, the can flap 200 on bag is formed by bag 100 and heat-sealing; Content need carry out can by the can flap after opening, and perhaps pours out and takes.This kind can port cover structure and the structure of fixing with packaging bag are all similar with the current packaging bag.
