一、轻而坚固的瓶不管是玻璃瓶,还是塑料瓶,都要向轻量化发展,而且要更加坚固. 对于玻璃瓶来说,为了节约能源和原材料,无疑要实现轻量化,如传统的“ALP”瓶重620克/只,而轻量化的“ALP”瓶只重330克,这种轻量化的瓶是要回收使用的,这样,有利于更好地使用原材料,并便于在玻璃瓶表面涂塑,从而一方面使瓶更加坚固,另一方面也可减少灌装时的噪音. 塑料瓶和其它塑料容器,如今十分普及.在生产上,运用挤压——吹塑工艺时,往往对材料进行双向拉伸,这种制作技术广泛地运用于聚酯瓶、聚丙烯瓶和聚氯乙烯瓶的生产.在
First, the light and strong bottle Whether it is glass bottles, or plastic bottles, have to develop lightweight, but also more solid.For glass bottles, in order to save energy and raw materials, it is undoubtedly to achieve weight reduction, such as the traditional “ ALP ”weighs 620 grams per pound while the lightweight“ ALP ”bottle weighs only 330 grams. This lightweight bottle is recycled for better raw material use and easy handling on the glass surface Plastic, which makes the bottle more solid on the one hand, on the other hand can also reduce the noise filling. Plastic bottles and other plastic containers, is now very popular in the production, the use of extrusion - blow molding process, often on Material biaxial stretching, this production technology is widely used in the production of polyester bottles, polypropylene bottles and polyvinyl chloride bottles in
