Abstract
The utility model relates to a packing plastic hose with omnibearing high barrier property, which aims at solving the problems of the prior packing plastic hose that the oxygen in the air cannot be completely prevented from penetrating into the interior of the hose, and comprises a mouth piece and a hose body, wherein the hose body comprises a five-layer composite structure with a barrier layer, and the mouth piece is of a six-layer composite structure with a barrier layer. The mouth piece and the hose body are provided with the barrier layer, so that the oxygen transmission rate of the entire hose is less than 15cm<3>/m<2> under the air pressure of 0.1 MPa for 24 hours, thereby actually playing the omnibearing high barrier effect and effectively protecting the products such as the cosmetics.
Description
Technical field
The utility model relates to a kind of packing plastics flexible pipe.
Background technology
The packing plastics flexible pipe that is used for the packings of product such as cosmetics, medicine at present is made of tube head and pipe shaft one, and pipe shaft can be individual layer or five-layer structure, but tube head all is a single layer structure.Can react and go bad in order to prevent that some product in the packing plastics flexible pipe from contacting with oxygen, pipe shaft is the multi-layer compound structure that contains barrier layer, perhaps at the individual layer pipe shaft surface coating high barrier UV of no barrier gloss oil.Because tube head is single layer, and is without hindrance every effect, infiltrate in the pipe so still have minor amounts of oxygen, react with content, the homogeneous tube oxygen permeability of this structure flexible pipe is 15～20cm
3/ m
224h0.1MPa.
Summary of the invention
The purpose of this utility model is to exist at present packing plastics flexible pipe and can not intercepts the problem of airborne oxygen to the flexible pipe internal penetration fully, provides a kind of tube head also to have the cosmetic package plastic hose with comprehensive high barrier of barrier.
The purpose of this utility model is achieved in that the utility model comprises tube head and pipe shaft, and described pipe shaft is five layers of composite structure that include barrier layer, and described tube head is six layers of composite structure that include barrier layer.
Five of pipe shaft layers of composite structure are followed successively by polyethylene layer, adhesive phase, barrier layer, adhesive phase, polyethylene layer from the inside to the outside in the utility model.
Six of tube head layers of composite structure are followed successively by polyethylene layer, adhesive phase, barrier layer, adhesive phase, polyethylene layer, polyethylene layer from the inside to the outside in the utility model.
The material of the barrier layer of tube head and pipe shaft can adopt Ethylene vinyl alcohol copolymer in the utility model.Adhesive phase adopts anhydride modified linear low density of polyethylene poly-mer.
Technique effect of the present utility model is: the utility model all is provided with barrier layer at tube head and pipe shaft, the oxygen permeability＜15cm of homogeneous tube
3/ m
224h0.1MPa, really accomplish comprehensive high barrier, products such as the more effective protection cosmetics of energy.

The specific embodiment
Referring to Fig. 1 to Fig. 3, existing a kind of packing plastics flexible pipe comprises tube head 1 and pipe shaft 2, tube head 1 is a single layer structure, make by polyethylene, pipe shaft 2 is five layers of composite structure that include barrier layer 203, and is interior to being followed successively by polyethylene layer 201, adhesive phase 202, barrier layer 203, adhesive phase 204, polyethylene layer 205 outward.
Referring to Fig. 4 to Fig. 6, the packing plastics flexible pipe of present embodiment comprises tube head 3 and the pipe shaft 4 that is connected as a single entity, tube head 3 is six layers of composite structure that include barrier layer 303, these six layers of composite structures are followed successively by polyethylene layer 301 (being the PE layer) from the inside to the outside, adhesive phase 302, barrier layer 303, adhesive phase 304, polyethylene layer 305, polyethylene layer 306, the thickness of outermost polyethylene layer 306 is thicker, also thicker than other gross thickness of five layers, on outermost polyethylene layer 306, be provided with screw thread, be used for making up with pipe cap, the outermost layer 306 of tube head mainly plays support and bonded assembly effect, and other five-layer structure mainly takes blocking effect; Pipe shaft 4 is five layers of composite structure that include barrier layer 403, is followed successively by polyethylene layer 401, adhesive phase 402, barrier layer 403, adhesive phase 404, polyethylene layer 405 from the inside to the outside.The material of the barrier layer of tube head 3 and pipe shaft 4 is Ethylene vinyl alcohol copolymer in the present embodiment, and commodity are called EVOH, and the adhesives of adhesive phase adopts anhydride modified linear low density of polyethylene poly-mer (being ADMER).
In the present embodiment, pipe shaft 4 is by coextrusion processes production, the five-layer structure from the inside to the outside of tube head 3 (being polyethylene layer 301, adhesive phase 302, barrier layer 303, adhesive phase 304, polyethylene layer 305) is by the coextrusion processes coextrusion, the outermost layer of tube head 3 (being polyethylene layer 306) is by Shooting Technique production, thereby the above-mentioned five-layer structure of tube head 3 and outermost layer are connected as a single entity by Shooting Technique and constitute tube head 3, and the head technology of this connection procedure and tube head 3 and pipe shaft 4 employing injection mouldings is carried out the bonded assembly process and carried out simultaneously.
