按美国俄亥俄州,克里弗兰城弗里道尼业集团公司的工业分析家威廉威塞称塑料容器在美国的需要量每年将增加2.8％。到1998年达330万吨(73亿磅)。 他认为塑料容器在美国市场需要量的增长主要有二个因,即防护性能高以及成本和特性优于其他原料,例如玻璃,金属和纸等。 但威廉又说由于延迟使用期和资源的还原作用将预示更多的效益。塑料瓶将占所需容器总量的75％,并根据性能的优点(例重量轻和抗破裂性能)和技术的改进(例热充填和共挤出)提供机会。
According to William Weiser, an industrial analyst at Freedonia Group in Cleveland, Ohio, the demand for plastic containers in the United States will increase by 2.8% annually. It reached 3.3 million tons (7.3 billion pounds) by 1998. He believes that the growth in demand for plastic containers in the U.S. market is mainly due to two factors: high protection performance and cost and characteristics superior to other materials such as glass, metal and paper. However, William added that due to the delayed use period and the reduction of resources, it will indicate more benefits. Plastic bottles will account for 75% of the total volume of containers needed, and provide opportunities based on performance advantages (eg, light weight and resistance to breakage) and technological improvements (eg, hot fill and co-extrusion).
