492.全球糖果和糕点包装市场报告（2015-2019年）
[橡胶和塑料制品业,造纸和纸制品业] [2015-01-02]
Confectionery products can be classified into three segments: Chocolate, Sugar Confectionery, and Gum. These items are popular among all age groups. In addition, the sale of confectionery products is independent of seasons or occasions. Packaging is an essential part of confectionery goods to preserve their quality, texture, and taste before they reach the end-customers. Confectionery dealers always look for packaging vendors that can provide appealing packaging solutions in terms of material, color, and innovations. This is critical to increase sales by enhancing product visibility.

493.全球拉伸和收缩膜市场报告（2015-2019年）
[橡胶和塑料制品业,化学纤维制造业] [2015-01-01]
Stretch and shrink films are highly engineered polythene films used for packaging goods. These films have special chemical properties, which make them differ in their flexibility and stretch ability. Stretch films are stretchable, elastic thin polythene films used to wrap around pallet loads. Shrink films are thin films that are wrapped around a single product or commodity and require the application of heat for packing. These films help to prevent the spoilage of goods from air and moisture, thus enhancing the quality of packaged products.

497.PS/PETG共混物的流变性能和发泡行为研究
[橡胶和塑料制品业] [2014-12-30]
采用密炼机制备了聚苯乙烯(PS)和聚对苯二甲酸乙二醇酯-1,4-环己二甲醇酯(PETG)共混物;以超临界二氧化碳(CO2)为物理发泡剂,采用釜压法制备了PS和PS/PETG共混物发泡试样。通过旋转流变仪、扫描电子显微镜对PS和PS/PETG共混物的流变性能和泡沫的泡孔形态进行了表征。结果表明,加入PETG没有对PS的流变性能产生明显的影响,但对PS泡沫的泡孔形态影响显著,加入10%的PETG时,其平均泡孔直径由纯PS的22.68μm降至7.58μm,泡孔密度由3.45×108个/cm3提高到4.47×109个/cm3,泡孔尺寸分布明显变窄,说明PETG在PS中起到明显的气泡成核作用。
