Wherein, described skin is modified, high temperature resistant polyester material;
Described internal layer is modified polypropene material;
Described enclosing cover is modified, high temperature resistant polyester material;
Described intermediate washer is polyisoprene material;
Described inner cap is modified polypropene material;
Double-layer plastic bottle involved in the present invention, outer with modified, high temperature resistant polyester (PET) raw material, there is the thick modulability of bottle germ wall good; Free inflation is good; The transparency, rigidity, oozing property of resistance are good; The compatibility is good; Transparency is high, meets the advantage of packaged food, requirements for pharmaceuticals.
Internal layer uses PP raw material, and PP raw material advantage: good heat resistance, can resistance to 121 degree of moist heat sterilizations.Have good stress cracking resistance, have very high flexible life, PP product light weight, good toughness, chemical resistance are good.
In order to reach another object, the technical solution used in the present invention is: a kind of production technology of double-layer plastic infusion bottle, it is characterized in that comprising bottle processed, system lid and canned capping processes.
Wherein, in described bottle process processed, concrete steps are as follows:
(1) modified, high temperature resistant polyester granules is outer by injection machine injection moulding bottle embryo;
(2) modified polypropene pellet is passed through injection machine injection moulding bottle embryo internal layer:
(3) with bottle embryo unit mahine, bottle embryo skin is become bottle embryo assembly with bottle embryo inner-layer combination;
(4) by bottle embryo assembly Baking out in lamp box;
(5) the bottle embryo assembly of heating is transferred in mould, after longitudinal stretching, with in press compressed air to be blown into double-deck plastic bottle bottle.
In described lid process processed, concrete steps are as follows:
(1) modified, high temperature resistant polyester granules is passed through injection machine injection moulding composite cover enclosing cover;
(2) modified polypropene pellet is passed through injection machine injection moulding composite cover inner cap;
(3) with unit mahine, composite cover enclosing cover is embedded in pad, then embeds composite cover inner cap fixed Combination integral, composite cover.
In described filling and sealing process, concrete steps are as follows:
(1) to liquid drug in the double-deck plastic bottle bottle be blown into
(2) carry out seal welding after fill, during welding, composite cover enclosing cover welds with multilamellar plastic bottle skin and fuses, and composite cover inner cap and double-deck plastic bottle inner welded fuse, and finally become double-layer plastic infusion bottle.
Beneficial effect of the present invention: the bottle embryo of different layers adopts different raw materials, different functions given by the raw material of every layer; Skin can use and material modifiedly meet the function such as high-barrier, lucifuge; Internal layer uses the good material of the compatibility to meet medicine compatibility requirements, and it is low that this technique has cost; Output is high; Be applicable to the feature produced in enormous quantities.
