Abstract
The utility model relates to a high-barrier composite plastic bottle, which comprises a polyethylene layer. The utility model is characterized in that a middle material layer and a high-barrier composite layer are also arranged at the inner side of the polyethylene layer in sequence, wherein, bonding agent is filled on the middle material layer, and ethylene-vinyl alcohol copolymer is filled on the high-barrier composite layer. The other purpose of the utility model is to increase a visual line on an outermost layer on the basis of a three-layer structure, non transparent polyethylene is filled on the polyethylene layer, the visual line is also arranged, the visual line is arranged on the polyethylene layer and composed of the transparent material, and the transparent material can be the transparent polyethylene material and can also be other material. Compared with the prior art, the utility model has the advantages that because the high-barrier composite layer is arranged, the plastic bottle has high barrier property; because the visual line is arranged on the outermost layer, users can observe the liquid in the plastic bottle through the visual line.
Description
Technical field
The utility model relates to a kind of container, more specifically to a kind of high-barrier composite plastic bottle.
Background technology
Existing plastic bottle adopts common polyethylene (PE) material to make mostly, does not have high barrier.
Secondly, these plastic bottles do not have visible light, and the user can't observe the liquid in the plastic bottle.
Summary of the invention
The purpose of this utility model is that prior art is improved, and a kind of high-barrier composite plastic bottle is provided, and has high barrier, and the technical scheme of employing is as follows:
High-barrier composite plastic bottle of the present utility model, comprise polyethylene layer, it is characterized in that: the polyethylene layer inboard also is provided with the middle level bed of material and high-barrier composite bed successively, and the described middle level bed of material is an adhesives, and the high-barrier composite bed is Ethylene vinyl alcohol copolymer (English abbreviates EVOH as).
Another purpose of the present utility model is on the basis of three-decker, increases visible light at outermost layer, therefore also is provided with visible light, described polyethylene layer is opaque polyethylene, and visible light is located at polyethylene layer, is made up of transparent material, can be transparent polyethylene, also can be other material.
The utility model beneficial effect against existing technologies is, owing to be provided with the high-barrier composite bed, so plastic bottle has high barrier, because outermost layer is provided with visible light, so the user can observe liquid in the plastic bottle by visible light.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment;
Fig. 2 be preferred embodiment A-A shown in Figure 1 to cutaway view.
The specific embodiment
As shown in Figure 1, 2, high-barrier composite plastic bottle in this preferred embodiment comprises polyethylene layer 1, and polyethylene layer 1 inboard also is provided with the middle level bed of material 2 and high-barrier composite bed 3 successively, the described middle level bed of material 2 is an adhesives, and high-barrier composite bed 3 is an ethylene-vinyl alcohol copolymer.
Described polyethylene layer 1 is opaque polyethylene.
The described visible light 4 that also is provided with, visible light is located at polyethylene layer 1, is made up of transparent material, is transparent polyethylene.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Be all equivalents of being done according to claim scope of the present utility model, be the utility model claim scope and cover.
