We have learned, in the five packaging products, only the metal packaging can be repeatedly used, is not depreciate products, plastic packaging instead of metal packaging is a very small possibility.

Around the tin box packaging industry and the formation of the middle and lower reaches of the industry calls for led by metal containers of China packaging federation committee organization construction recycling, recycling alliance has been sound.After seven years of unremitting efforts, to solve the problem of subject of tin box packaging recovery, recycling, with tin box packaging industry is given priority to, a middle and lower reaches of enterprises to participate in operation of metal tin box packaging recycling and recycling league national organization was born at last.

Zhejiang yiwu a founded in 22 years ago tinplate easy open cover, aluminum cover manufacturing enterprises, factory scraps from January 1200 tons!The national conservative estimates there are 500 such enterprises.At the same time, our country there are a lot of junk food cans no scientific recycle and regeneration of abandoned channel.Experts say that because the metal packaging absence caused by waste recovery and recycling systems are very amazing!

PET is a kind of pressure resistance of polyester material, in the 70 s by the United States Pepsi company onto the market first.Because the price is cheap, transparency, good air tightness and pressure strength, global reach 2 million tons in 1995, 37% of the global soft drink market.But 犘 犈 犜 bottle there are many defects in acid and alkali resistance and heat resistance, such as the bottle above 60 ℃, cervical softening and volume shrinkage, therefore non-carbonated beverages must use the instantaneous ultra high temperature sterilization (UHT), under the condition of aseptic filling sealing after cooling, it's about filling environment put forward strict requirements and equipment technology.Japan, LTD (ASB) machinery manufacturing company in the early ninety s to market HSO series of heat-resistant PET bottle (PEN) production technology and equipment, namely in the ordinary PET production process to join an oven heating process, shorten the heating time of tube billet originally, improve the crystallization temperature, so as to improve the effect of crystallization rate and crystallization, the PEN bottle can realize hot filling, namely in 85-90 ℃ condition for tea beverage filling.Tea drink hot filling to simplify the production process, ensure the quality of tea products provide favorable conditions.ITO park in Japan, asahi, suntory and other companies of heat-resisting PEN to obtain better economic benefit.But since the equipment cost is too high (a line around .5 million), the bottle price is ordinary PET bottle of 1 or more times, more daunting.

In order to find suitable for China's national conditions, quality and cheap, modelling is chic, and suitable for hot tea beverage packaging, the author found that the Japanese in 1996 nagano FONTIER cooperation with the United States, the new company?Two-way stretch blow molding technology, and to Asian markets by Hong Kong jia da industrial company launched EFB2000P EFB1000R and two types of two-way stretch blow molding machine. Using ordinary note (squeeze) blows method of production of polypropylene (PP) hollow container, barrier property, heat resistance, good rigidity than PET, but its transparency and impact resistance at low temperature is PET is poor, so ordinary slow progress in the application of PP in the food packaging container.Note (squeeze) a pull a two-way tensile PET bottle blowing process of many performance is greatly improved, the weight after stretching, save raw materials.

Metal packaging industry in our country to adapt to the resource saving and environmentally friendly development model, today launched major moves, the metal packaging recycling and recycling alliance held in Beijing on July 4, the second Beijing international packaging exhibition of metal packaging BBS was founded at the venue.
