Description

A kind of PET Beer Bottle and preparation method thereof
Technical field
The application belongs to PET preparation field, particularly relates to a kind of PET Beer Bottle and preparation method thereof.
Background technology
Beer is the most ancient alcoholic beverage of the mankind, the beverage that is number three of consumption in the world after being water and tea.Beer imports China in earlier 1900s, belongs to external wine kind.Beer is translated into Chinese " beer " according to English Beer, is called " beer ", uses till today.Beer with Fructus Hordei Germinatus, hops, water for main raw material, through the full carbonated low-alcoholic wine of yeast fermentation effect brew.Present international beer major part all adds auxiliary material.The consumption of some national regulation auxiliary materials amounts to and is no more than 50% of Fructus Hordei Germinatus consumption.In Germany, except export beers, German home sale beer does not use auxiliary material without exception.In 2009, beer production about 5,867 ten thousand kilolitre in Asia, first excursion Europe, became the beer production ground that the whole world is maximum.Hops contains protein, VITAMIN, volatile oil, bitter principle, resin etc., has cardiac stimulant, stomach invigorating, diuresis, the medical effects such as analgesia, all has good auxiliary curative effect to essential hypertension, heart trouble and tuberculosis etc.Puerpera has the beer, and to increase parent milk, makes baby obtain nutrition more fully.Beer is that reducing temperature of heatstroke prevention summer and autumn is quenched one's thirst the refreshment drink of hidroschesis, and study according to medical science and beverage experts, beer contains the alcohol of 4%, can stimulate circulation.Excessively drink freezing beer imapirment of the spleen and stomach, increase the weight of moisture in body, unhealthful.PET Beer Bottle is also in the test spread stage at home, and its barrier and antioxidant are to be further improved in addition, high price and be difficult to recycle, and is its key applied of restriction.` he also illustrate: ` vial bid 0.8 yuan, the PET bottle with capacity is 0.9 ~ 1.2 yuan, if consider the advantages such as PET bottle is light, safety, trucking costs are low, expensive one or two mao of PET bottle, enterprise can accept reluctantly.But the vial overwhelming majority can reclaim, and can be recycled, and PET bottle can only be used as recovery and regeneration of waste plastics, all will buy new bottle exactly to beer producers after cleaning, sterilization and disinfection at every turn.And this also directly affects the purchase of human consumer, the such as Yanjing Brewery of price 2 yuan, with glass bottle, if human consumer returns the bottle cash pledge that bottle can obtain 0.5 yuan, be equivalent to every bottled beer and only sell 1.5 yuan, PET bottle dress beer does not then have cash pledge and returns problem, such one calculates, the price difference of PET bottle and vial is not just the problem of a jiao two jiaos, but five jiaos of anises are even more, and Here it is, and enterprise is reluctant uses the reason of PET bottle.
Beer Bottle mostly is vial, and neck is lower thick shape carefully, nails on bottle cap, can dispatch from the factory after being extracted out by air.Finish off rear beer dead soldier and can be recovered utilization.At high temperature similar pop bottle is easily blasted.Beer Bottle is used for celebration, and what such as west was popular open, and wine celebrates that ceremony utilizes the air pressure in Beer Bottle that the beer of the inside is gushed out just, and expression is celebrated joyously.In Zhuhai, richness is one of national maximum pet bottle production base, and its product, through Coca-Cola and pepsi cola accreditation, is that " two is happy " specifies product purchasing.Current the said firm intends upper polyester beer bottle project.Project situation: utilize the said firm and this new high-tech product achievement of the successful pet Beer Bottle of external joint development, significantly improve the performance of pet bottle resistance oxygen and isolated carbonic acid gas, meet the requirement of beer preservation and can pasteurization be passed through, make pet Beer Bottle carry out commercialization, scale operation, thus provide novel packaging for beer enterprise.The said firm is the domestic enterprise entering this new high-tech product business development the earliest at present.Gross investment and rights and interests ratio: project adopts Chinese-foreign joint mode to manage, gross investment 1,900 ten thousand dollars (amounting to Renminbi 15,770 ten thousand yuan), the said firm provides funds 1,425 ten thousand dollars (amounting to Renminbi 11827.5 ten thousand yuan), occupies co-partnership company 75% rights and interests.Three nine-day periods after the winter solstice brew-house in Shijiazhuang has carried out the test of Plastic Bottle.This factory is attempting adopting the pure draught beer of plastic bottle at present, mainly consider that the level of the anti-high pressure of Plastic Bottle has no problem, but the performance of high temperature resistance and gas barrier gas need further observation.Because beer needs in process of production through high-temperature sterilization, require that bottle can be high temperature resistant about 300 DEG C, and the sensitivity shortcoming that plastics are fatal just to temperature.In addition, Beer Bottle barrier not only has influence on the mouthfeel of wine, also affects the shelf lives of wine.Decision plastic beer bottle is proceeded technique improvement or promotes the use of on a large scale by test result.
Pet Beer Bottle is a kind of take polyethylene terephthalate as the Beer Bottle that material is made, and the English of polyethylene terephthalate is called Polythylene terephthalate, is called for short pet, pet Beer Bottle and gains the name thus.The beer packed brand of the pet that current Chinese market can be seen mainly contains three and to get profit M Ⅸ beer, belongs to fruity beer series, packs bright-coloured, have three kinds of tastes such as honey peach; Belgium's Maxwell beer, this beer follows Belgian Martens local flavor, mellow; Silver lion beer, this beer acts on American smart wine theory, and pack draft beer by PET bottle, mouthfeel is fresh pure; Blue shellfish beer, after integrating with blue zone China, release pet bottle, mouthfeel is heavier, and it is strong to kill mouthful power.Due to the inherent defect of beer bottle and the superiority of plastic containers, plastic beer bottle is the high-tech product that International Beer industry and packing business are are competitively researched and developed energetically, and plastic beer bottle is brought into use in European and American developed countries.Predict that the whole world in 2000 will reach 1,000,000 tons for the production of the pet of plastic beer bottle.Estimate that becoming biggest market reaches 250,000 tons to North America in 2005, take second place in Asia-Pacific, West Europe reaches 200,000 tons.China is second-biggest-in-the-world beer production state, and within 1998, Chinese beer output is 1,987 ten thousand tons, amounts to 640ml calculation of capacity, about needs Beer Bottle about 25,000,000,000.According to national regulation, beer enterprise must all use the Beer Bottle meeting GB gb4544-1996 from 1 day April in 1999, non-" b " bottle will be eliminated in recent years from beer brewery, add that " b " bottle arriving the time limit starts to replace successively, on annual market, the breach of Beer Bottle is very big, with 2000 afterwards every year improve 1-3 percentage point of expectation, calendar year 2001 Beer Bottle sales volume just can have 5,000 ten thousand-10,000 ten thousand, 1.5 hundred million-2 hundred million within 2002, can be reached.Therefore, beer container be need Chinese synthetic resins and plastic industry exploitation a large market.
Polyethylene terephthalate (P E T) bottle has many advantages, and the performance as resistance CO2, O2 and vapor permeation is high, and intensity, shock-resistance, chemical resistance and resistance to pressure are high, and very well, appearance property is good for transparency and glossiness.These advantages make P E T bottle be widely used in packaging soft drink, tea drink, fruit juice, medicine, food etc., such as, in packaging soda pop, mineral water etc., achieve very large success.But, because beer is to the particular requirement of wrapping material, make PET still be difficult to the traditional wrapping material (glass and metal) of a large amount of replacement.Realize beer packed plastic, 3 problems the most basic must be solved.First be barrier problem.The beer usual shelf lives is 120 d, so require that Beer Bottle can not be greater than 1 × 10-6 g to the infiltration capacity of O2 at 120d, is no more than 15% to the loss of CO2, and this requirement is 2 ~ 5 times of common PET bottle barrier.Next is temperature resistance problem.Require that bottle can stand the pasteurize carrying out 15 min at 78 DEG C, second-order transition temperature is that the PET of 78 DEG C cannot bear this processing requirement.3rd is price factor, and PET bottle cost is higher than vial cost.Mainly concentrate on the research of PET bottle and improve its heat-resisting and barrier property aspect, barrier property becomes the focus closely studied during the last ten years.And popularizing along with humanity concept, and the formation of novel harmonious society, design PET Beer Bottle that a kind of oxygen-barrier property is good, transmittance is high and shock strength is high and preparation method thereof and be very important.
