This paper will review the markets, business, technology, and future trends concerning the use of PVC bottles in various packaging segments such as mineral water—flat and low carbonated, wine, fruit juice, and edible oils in Western Europe. The market and business sections will include the major producers of mineral water bottles, capacity of PVC water bottle compounds, and bottles. Activities of major PVC bottle compound producers and bottlers to further improve quality of PVC premix and bottles produced will also be discussed. Also discussed will be the reasons for the success of PVC bottles for packaging mineral water and other food related items. The technology related to the production of PVC bottles for packaging mineral water such as manufacturing equipment, PVC compound systems, and bottle properties will be presented. In addition, future trends concerning PVC vs oriented PVC bottles for flat and carbonated mineral waters as well as new additives for PVC bottle compounds and technology under consideration will be discussed. 相似文献

A study was carried out of the development of orientation during processing of conventional blow molded bottles made from low density polyethylene (LDPE), linear low density polyethylene (LLDPE), and high density polyethylene (HDPE). The level of molecular orientation was found to be relatively low in all of the polyethylene bottles examined; it increased with increasing inflation pressure and decreasing extrusion temperature. Pole figures for the HDPE bottles indicated a slight a-axis orientation toward the circumferential direction of the bottle. The b-axes, which correspond to the lamellar growth direction, tend to be parallel to the bottle thickness direction. A comparison was made of the structure developed in blow molded bottles and blown films. The results for both films and bottles indicate that crystallization during processing involves both an increase in level of molecular orientation and an increased tendency toward biaxiality. Based on pole figures and small angle X-ray scattering patterns, a morphological model for HDPE blow molded bottles is proposed. 相似文献
