Abstract
The utility model discloses an aluminum and plastic compound film with high seal and leakage resistance used for packing liquid dairy food and has a hiberarchy, which can be a printable layer, a glue layer, an aluminum plating layer, a polyethylene layer, a reinforced layer, and a heat insulation layer in order from the outside to the inside. The utility model has the advantages of good air insulation performance, strong leakage resistance, and good shading effect, and is quite applicable for packing liquid dairy food.
Description
Technical field
The utility model relates to a kind of structure of composite membrane, and specifically a kind of packing liquid dairy product high-barrier is prevented the dialysis aluminum-plastic composite membrane.
Background technology
The liquid dairy product plastic flexible package film that generally uses is made up of three-layer polyethylene at present, and the defective that this product exists is: the one, and oxygen-barrier property is poor, causes the dairy products shelf-life short, and dairy products fragrance can not be lasting; The 2nd, dairy products there is pollution, this is because this kind film contains low molecular compound, and these low molecular compounds pollute dairy products easily, and influence the mouthfeel of dairy products.
Summary of the invention
The purpose of this utility model is to develop a kind of liquid dairy product to pack, prevent the dialysis aluminum-plastic composite membrane with high-barrier.
The technical matters that barrier difference and the packaging film itself to oxygen that is existing three-layer polyethylene liquid packaging film exists to be solved in the utility model pollutes the packaging dairy products.
The technical solution of the utility model is: it is a hierarchical structure, and this hierarchical structure is followed successively by printable layer, adhesive layer, aluminium coated, polyethylene layer, enhancement layer and hot sealing layer from outside to inside.
The utility model is compared with traditional liquid dairy product plastic flexible package film, has got rid of carbon black layer, uses aluminium coated instead, so it has high trapping oxygen barrier, high anti-dialysis, good being in the light property etc. very are suitable for making the packaging bag of dairy liquids.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in the figure, the utility model is a hierarchical structure, and this hierarchical structure is followed successively by printable layer 1, adhesive layer 2, aluminium coated 3, polyethylene layer 4, enhancement layer 5 and hot sealing layer 6 from outside to inside.
Printable layer 1 is a polyethylene layer, and enhancement layer 5 is the blended layer of high density polyethylene (HDPE) and low density polyethylene (LDPE) or the blended layer of high density polyethylene (HDPE) and linear low density polyethylene (LLDPE).
Aluminium coated 3 is an aluminum membranous layer for one deck.Hot sealing layer 6 is the blended layer of metallocene PE and low density polyethylene (LDPE).
Hierarchical structure of the present utility model also can have only two-layer structure, promptly has only two layers of aluminium coated and polyethylene layers.Or three-decker, printable layer, aluminium coated, polyethylene layer are promptly arranged.Or five-layer structure, printable layer, adhesive layer, aluminium coated, polyethylene layer, enhancement layer are promptly arranged, or printable layer, adhesive layer, aluminium coated, polyethylene layer, hot sealing layer.
Claims (2)
1, the anti-dialysis aluminum-plastic composite membrane of a kind of packing liquid dairy product high-barrier, it is a hierarchical structure, it is characterized in that this hierarchical structure is followed successively by printable layer, adhesive layer, aluminium coated, polyethylene layer, enhancement layer and hot sealing layer from outside to inside.
2, the anti-dialysis aluminum-plastic composite membrane of packing liquid dairy product high-barrier according to claim 1 is characterized in that printable layer is a polyethylene layer; Enhancement layer is the blended layer of high density polyethylene (HDPE) and low density polyethylene (LDPE), or the blended layer of high density polyethylene (HDPE) and linear low density polyethylene (LLDPE); Hot sealing layer is the blended layer of metallocene PE and low density polyethylene (LDPE); Polyethylene layer is selected a kind of in the polyethylene layer of low density polyethylene layer, linear low density polyethylene (LLDPE) layer, medium density polyethylene layer, high-density polyethylene layer, metallocene catalysis for use, or selects the blended layer of at least two kinds of compositions in the polyethylene of low density polyethylene (LDPE), linear low density polyethylene (LLDPE), medium density polyethylene, high density polyethylene (HDPE) and metallocene catalysis for use.
