Abstract

The present invention relates to beverage technology, be particularly related to BOPP beverage bottle of a kind of bottleneck 38mm and preparation method thereof, the BOPP beverage bottle of this bottleneck 38mm, comprise bottle, bottleneck and adaptive bottle cap with it, its special character is: the threaded external diameter of bottleneck of bottle is that 38mm, volume are 150-1500ml, after high-temperature filling sterilization, bottleneck and airtightness of bottle cap are good, and cost is low, easy to use.

Description

BOPP beverage bottle of a kind of bottleneck 38mm and preparation method thereof
(1) technical field
The present invention relates to beverage technology, particularly BOPP beverage bottle of a kind of bottleneck 38mm and preparation method thereof, concreteRelating to its material is that BOPP, bottleneck are the sealing stability of bottleneck, bottle, bottleneck and the bottle cap of 38mm beverage bottle.
(2) background technology
Beverage bottle material used is mainly polyester (PET), polypropylene (PP), polyethylene (PE) etc. At present, beverage heat is filled withOn dress market, mostly adopt PET bottle. PET material has good barrier properties for gases and chemical stability, and has good toughness,Its hot strength is high, transparent, glossiness is good, but very easily moisture absorption, therefore, PET bottle needs to be undertaken by special equipment before processingDry processing. Common PET bottle non-refractory, the typical approach that changes its performance is to improve degree of crystallinity, adds heat fixed in the time of bottle blowingType technique, the manufacture craft of bottle base also will change, and is mainly the crystallization of bottleneck, and along with degree of crystallinity improves, PET bottle can be resistance to 85 DEG CTo the temperature of 95 DEG C.
Biaxial stretch-formed polypropylene (BOPP) bottle, because polypropylene material price is lower, stability, transparent good, nonhygroscopic, resistance toWarm nature is good, and shortcoming is that glossiness and barrier are not so good as PET material, but can improve the barrier of polypropylene vial by biaxial tensionAnd temperature tolerance.
At present only resistance to 93 DEG C of high temperature of PET hot-filling bottle, but BOPP bottle can resistance to 100 DEG C of high temperature, the hot filling of Zhe Shi Soft Drinks PlantIt is easy that technique becomes. Because PET bottle heat resistance is poor, must be by rational Design of perfume bottles to adapt to the temperature when fillingAnd pressure, all need special template in bottom and the bottom of bottle, therefore the PET of the heat filling beverage such as splendid attire tea, fruit juice on marketDoleiform is similar, and BOPP bottle is because heat resistance is good, and not harsh to Design of perfume bottles requirement, Design of perfume bottles can be very cleverLive.
Compare PET bottle, the most important is that BOPP bottle is nonhygroscopic. Due to the easy moisture absorption of PET bottle, cause degree of crystallinity to decline,Destroy the heat resistance of bottle, can only preserve at most 14 days, this has just caused the under-capacity operation in dull season of PET bottle production equipment, busy seasonSupply falls short of demand. BOPP bottle can be preserved the several years and heat resistance is constant, equals to have improved capacity utilization.
In price, PET material cost is at least higher by 20% than BOPP material, and the price of BOPP has larger to drink enterpriseAttraction, now increasing producer also starts to select this material of BOPP, produces by note stretch blow technology law. CauseThe hot contraction ratio of BOPP material is larger, and after high-temperature filling or sterilization, the sealing of bottleneck is difficult to ensure, for ensureing bottle sealingThe stability of effect, the bottleneck specification of this material mostly is 28mm, and so far, on domestic market, also there is no bottleneck is the BOPP material of 38mmThe milk beverage bottle of matter.
(3) summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides BOPP beverage bottle and the preparation side thereof of a kind of bottleneck 38mmMethod, this beverage bottle cost is low, easy to use, and bottleneck is 38mm, and capacity is 340ml, and material is BOPP, has phase with it on beverage bottleAfter adaptation and high-temperature filling sterilization, seal the bottle cap of good stability.
The present invention is achieved through the following technical solutions:
Bottleneck is a BOPP beverage bottle of 38mm, comprises bottle, bottleneck and adaptive bottle cap with it, and its special character existsIn: the threaded external diameter of bottleneck of bottle is that 38mm, volume are 150-1500ml, bottleneck and airtightness of bottle cap after high-temperature filling sterilizationGood.
The preparation method of the bottleneck beverage bottle that is 38mm, its special character is: comprise the following steps:
(1) prepare stable bottle: by bottle type reasonable in design, on bottle, design reinforcement, ensure high-temperature fillingAfter sterilization, bottle is indeformable, and bottle good stability, to support the stability of bottleneck;
(2) determining of bottleneck data: determine applicable bottleneck internal-and external diameter, the data area of bottleneck thickness; Inside diameter ranges is29.80-30.00mm; External diameter scope is 34.20-34.50mm; Bottleneck thickness is 2.10-2.25mm.
(3) determining of bottle sealing: determine after the data area of bottleneck, select the material of bottle cap according to hot contraction ratio,According to the data of BOPP hot contraction ratio, bottleneck, select applicable bottle cap size, determine that bottle cap is PE material, internal sealed ring 30.15-30.25mm; Inside diameter ranges is not 37.80-38.20mm containing silk; External diameter scope is 38.80-39.80mm;
(4) preparing product: raw material is injected into pipe through injection machine, then, after cooling forming, places heating in baking box, then warpBottle blowing mould moulding in bottle blowing machine, finally by blow molding, pack to obtain final products, wherein injection machine is heated to 210-230DEG C, oven temperature is 140-160 DEG C, bottle blowing air pressure 2MPa.
The invention has the beneficial effects as follows: material prepared by the present invention is BOPP, the beverage bottle that bottleneck is 38mm, high-temperature fillingAfter sterilization, bottleneck and airtightness of bottle cap are good, and cost is low, easy to use.
