Abstract
The utility model relates to a multilayer co-extrusion water bag film. The co-extrusion water bag film is a seven-layer co-extrusion films which comprises a first metallocene polyethylene layer (1), a first LLDPE (Linear Low Density Polyethylene) layer (2), a first bonding layer (3), a nylon layer (4), a second bonding layer (5), a second LLDPE layer (6) and a second metallocene polyethylene layer (7) from top to bottom. The multilayer co-extrusion water bag film has the advantages of good toughness, strong loading capacity and high anti-permeability, has no undesirable odor, and is not liable to cause water contamination and ensures the water safety.
Description
Technical field
The utility model relates to a kind of multi-layer co-extruded water bag film, is mainly used in the packing of drinking water.
Background technology
Bag-pack drinking water is the upgrading products of barreled drinking water.Packed water is compared with bottled water, and biggest advantage is fundamentally to have stopped " secondary pollution " of drinking-water.Packed water is compared with bottled water, and the water outlet principle of the two is completely different, and packed water is the normal pressure water outlet by the atmospheric pressure water outlet, and bottled water is the negative pressure water outlet by the air-water displacement water outlet; Drinking of packed water is omnidistance sealing, do not contact from start to finish with air, avoided secondary pollution, it then is that full open model is drunk that bottled water is drunk, its essence of process of having drunk into the air of bucketful from the drinking-water of bucketful is exactly a contaminated process of drinking-water, so the problem of " secondary pollution " of bottled water is unavoidable.Packed in addition water before being filled with water and take up room after using little, during the storage transportation flexibly, convenient, its range of application is more and more widely.The packing water bag of packed water be owing to need bear enormous pressure, so preparation water bag film has been proposed higher requirement, requires its good toughness, bearing capacity is strong, anti-permeability is strong, in addition, because it contacts with drinking water, requires its free from extraneous odour, with assurance water quality.Conventional film is difficult to reach this kind performance requirement.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of good toughness, bearing capacity is strong, anti-permeability is strong, the multi-layer co-extruded water bag film of free from extraneous odour.
The purpose of this utility model is achieved in that a kind of multi-layer co-extruded water bag film, described water bag film is the seven-layer co-extrusion film, and it is followed successively by from top to bottom: the first metallocene PE layer, first linear low density polyethylene layer, first adhesive layer, nylon layer, second adhesive layer, second linear low density polyethylene layer and the second metallocene PE layer.
The beneficial effect of the multi-layer co-extruded water bag film of the utility model is:
The utility model was made of seven stacked adding, and by having complementary functions between the different plastic layers, improved its combination property;
The first metallocene PE layer and the second metallocene PE layer improve its low-temperature heat-sealing performance and heat seal strength as upper and lower top layer, and metallocene all adopts the free from extraneous odour metallocene;
First linear low density polyethylene layer and second linear low density polyethylene layer, the toughness and the bearing capacity of raising film;
Nylon layer improves barrier property and intensity;
First adhesive layer and second adhesive layer can well be bonded together the bad material of adjacent two kinds of compatibilities, and not delamination is easy to co-extrusion modling.
The layers of material free from extraneous odour can polluted-water, guarantees water quality safety.
In sum, the multi-layer co-extruded water bag film of the utility model, good toughness, bearing capacity are strong, and anti-permeability is strong, and free from extraneous odour, can not polluted-water is guaranteed water quality safety.
Description of drawings
The section structure schematic diagram of a kind of multi-layer co-extruded water bag film that Fig. 1 relates to for the utility model.
Among the figure:
The first metallocene PE layer 1, first linear low density polyethylene layer 2, first adhesive layer 3, nylon layer 4, second adhesive layer 5, second linear low density polyethylene layer 6, the second metallocene PE layer 7.
The specific embodiment
Referring to Fig. 1, a kind of multi-layer co-extruded water bag film that the utility model relates to, described water bag film is the seven-layer co-extrusion film, and it is followed successively by from top to bottom: the first metallocene PE layer 1, first LLDPE (LLDPE) layer, 2, first adhesive layer 3, nylon (PA) layer 4, second adhesive layer 5, second LLDPE (LLDPE) layer, the 6 and second metallocene PE layer 7.
