近年来,PET树脂在包装领域的应用爆炸性地增长,PET树脂在去年供应紧缺。主要原因是PET的取代价值,包括代替玻璃瓶,铝罐以及其它软性薄膜。由于PET被认为是“绿色”树脂以及可以回收再生的功能,使PET成为人们狂热地对之发生兴趣的材料。包装权威者预测,PET树脂的产量在未来五年中将以每年12％的幅度上升,同时在短期内PET的价格将会下降。 PET最早由杜邦公司的威廉姆· H·卡罗塞所发现。PET宁1956年首先大量地成功地应用于包装。 在1959年到1970年间,PET主要应用于熏肉的热成型包装材料。到了七十年代,熏肉热成型包装材料由尼龙所取代,PET转而趋向于吹制软饮料瓶代替了玻璃瓶。目前,PET树脂已穿透了整个北美市场。在欧洲,PET的应用也在迅速地增长,主要用于软饮料和瓶装水,代替了以前的玻璃瓶和PVC瓶。 PET瓶的下一个主要目标市场将是超级市场上一次性用量瓶（Single—serving Bottle）,即12英两软饮料瓶。 PET瓶上的标贴使用的为热收缩袖套式薄膜,将采用自动化机械进行印刷和封套,其最快的速度可以超过每分钟600个瓶。 当前,新引入市场的树脂为聚乙烯萘（Poly-ethylene Naphthalene—PEN）和PET/PEN混
In recent years, the application of PET resin in packaging has exploded, and PET resin was in short supply last year. The main reason is the replacement value of PET, including the replacement of glass bottles, aluminum cans and other flexible films. Because PET is considered a “green” resin and recyclable, it makes PET a source of fanatical interest in PET. Packaging authorities predict that PET resin production will increase by 12% annually over the next five years, while PET prices will decline in the short term. PET was first discovered by DuPont’s William H. Carousel. PET was first successfully applied to packaging in 1956. Between 1959 and 1970, PET was mainly used in the thermoforming packaging of bacon. By the seventies, the bacon thermoformed wrapper was replaced by nylon, which in turn tended to blow the soft drink bottle instead of the glass bottle. At present, PET resin has penetrated the entire North American market. In Europe, PET applications are also rapidly growing, mainly for soft drinks and bottled water, replacing the previous glass bottles and PVC bottles. The next major target market for PET bottles will be the single-serving bottle at the supermarket, a 12-inch soft drink bottle. The label on the PET bottle is a heat shrink sleeve film that will be printed and enveloped using automated machinery, with the fastest speeds exceeding 600 bottles per minute. Currently, the newly introduced resins are Poly-ethylene Naphthalene-PEN and PET / PEN
