Description

A kind of shading barrier plastic bottle

Technical field

The utility model relates to a kind of plastic containers, obstruct plastic bottle in particular for the high shading of the receivings such as oxidant.

Background technique

EVOH (ethylene/vinyl alcohol copolymer, Ethylene vinyl alcohol copolymer) is always using most More high barrier materials.The film type of this material is other than non-stretching type, and there are also biaxial tension types, binder application type Deng, aseptic packaging product is used for there are also heat resistant type in biaxial tension type, the barrier property of EVOH depends on the content of ethylene, and one As for when ethylene contents increase, barrier properties for gases decline is but easy to process.EVOH distinguishing feature is to gas with fabulous Barrier property and fabulous processability, otherwise see-through property, glossiness, mechanical strength, retractility, wearability, cold resistance and surface it is strong It spends all very excellent.In packaging field, composite membrane intermediate barrier layer is made in EVOH, is applied in all hardness and flexible packaging In；Aseptic packaging, hot tank and retort pouch, packaging dairy produce, meat, canned fruit juice and flavouring are used in grocery trade；Non- In terms of food, for packing solvent, chemicals, air conditioner structure part, petrol drum liner, electronic component etc..

But in strong oxidizer packaging, it is desirable that barrier plastic bottle or plastic flowerpot and higher sunshade are protected from light product also There are not suitable plastic containers can solve, the utility model is exactly the technical solution for proposing this respect.

Utility model content

The utility model aim is to prepare strong oxidizer Packaging Bottle, such as chlorine dioxide using structure and high barrier material The requirement of shading barrier plastic bottle is proposed when solution is packed, and requires shading barrier plastic bottle that there is higher sunshade to be protected from light energy Power, resists the influence of weather and illumination, and guarantees that strong oxidizer has a suitable plastic containers, and processes and uncomplicated.

The technical solution of the utility model is that a kind of shading barrier plastic bottle, bottle has PE layers, EVOH from outside to inside Layer, the 2nd PE layers of trilaminate material, every layer material is with a thickness of 0.25 ± 0.1mm；Wherein EVOH superficies are equipped with aluminium film；? Two PE layers of outer layer is cased with tubular black pyrocondensation plastic foil 5.

Trilaminate material, which is drawn into after cylinder, is cut into after body length that bottleneck and bottom of bottle is respectively prepared in melting in a mold again, PE has fabulous resistance to moisture, and EVOH is high shading barrier material, and superficies have the ability of aluminium film more reflection light, Protect medicament in bottle not by ultraviolet equal destruction, the drug effect of strong oxidizer is unaffected.The material surface singly aluminized cannot have The shaded effect got ready, but as use multilayer film co-extrusion when use one layer of black material when, this layer of black material will lead at this time The processing of preparatory increase black masterbatch additive is crossed, resin is not readily used for co-extrusion after processing.

Beneficial effect, the utility model is using structure and high barrier material and aluminizes plus prepared by one layer of black pyrocondensation plastic foil Strong oxidizer Packaging Bottle, at low cost, preparation uses prior art, and shading barrier plastic bottle or plastic flowerpot have higher screening Sun is protected from light ability, good to the effect of the ClO 2 solution of high concentration, keeps the shelf life of higher concentration ClO 2 solution obvious Extend, concentration decline curve can lag about two months；Superior technique solution is proposed to strong oxidizer packaging.

Detailed description of the invention

Fig. 1 is the utility model structure diagram.

Specific embodiment

As shown, shading barrier plastic bottle or plastic flowerpot, bottle have PE layer 1, evoh layer 2, second from the inside to the outside 3 trilaminate material of PE layer, every layer material is with a thickness of 0.25 ± 0.1mm；Wherein EVOH superficies have aluminium film 4, and evoh layer is thin In membrane pressure to other materials layer, for aluminium film direct plating on the layer of PE, trilaminate material is cut into body length after being drawn into cylinder Bottleneck and bottom of bottle is respectively prepared in melting in a mold again afterwards, and PE has fabulous resistance to moisture, and EVOH is high barrier material, outer layer Surface has the ability of aluminium film more reflection light, protects the medicament not destruction by ultraviolet grade, the drug effect of strong oxidizer in bottle It is unaffected.Aluminium film is aluminium-vapour deposition film；It is the important application of the utility model using aluminium-vapour deposition film, has shading to prevent two The lost effect of chlorine body is aoxidized, EVOH be can also be used as into barrier material coated on other synthetic resin packaging materials, risen It is compatible to enhancing barrier property effect and both effects that light is isolated, the storage problem of many chemicals can be completed.? Using in gas flush packaging technology, EVOH resin effectively remains carbon dioxide or nitrogen for protecting product.

The utility model is using coextrusion structure.EVOH resin combines with polyolefin and poly- phenol amine and forms framework.EVOH tree Lipid monolayer or plural layers squeeze out；Sheet material and profile coextrusion；Coextrusion blow molding；It is coextruded coating；It is laminated (or lamination) and infuses Modeling.Thermoforming secondary operation is carried out again is prepared into bottle.The 2nd PE layers of outer structure for being cased with black fever contracting plastic foil, in preparation process On it is also relatively simple: by 5 sets of PE or PP black pyrocondensation plastic foil in body, communicated V belt translation is in hot air tunnel furnace 90-115 Degree Temperature Treatment 30-20 seconds, is a semimechanized preparation process.PE or PP black pyrocondensation plastic foil selects 0.02mm Thickness specification.Using black heat shrinkable plastic film cylinder, it is big that the diameter of black heat shrinkable plastic film cylinder is greater than plastic bottle diameter 10mm, highly effect 2-3cm higher than the height of plastic bottle are more preferable.Bottle is equipped with bottle cap 6.

It should be understood by those ordinary skilled in the art that: the foregoing is merely specific embodiment of the utility model and , it is not intended to limit the utility model, it is within the spirit and principle of the utility model, any modification for being made, equivalent Replacement, improvement etc., should be included within the scope of protection of this utility model.
