随着现代食品工业的迅速发展,世界食品的包装材料、形式、容器等方面将发生很大变化。1.包装材料:将朝着软、轻、节省、方便和卫生的趋向发展。重量轻强度高的玻璃、金属、聚酯,将取代传统的玻璃和金属包装材料;纤维类的包装材料,如玻璃纸和半透明纸、防油纸等,将被定向拉伸聚丙稀、高密度和低密度薄膜、树脂薄膜等取代;包装材料将由传统的原材料转向以石油化工原料为主,其它包装材料将逐步淘汰。2.包装形式:将以无菌包装为现代化包装的标志。软性包装将迅速发展并被广泛采用;组成包装、防盗安全包装也将进一步受到重视;呆、大、笨、粗、厚的陈旧包装将被轻量化,小型化的包装所代替;小量定额包装将继续受到消费者的欢迎。另外,降低包装成本将通过改进包装材料性能来实现,而不是靠采用廉价的包装材料来解决。3.包装容器:传统的玻璃瓶和金属瓶将更新换代,逐步出现方便、启用后食品易于再存放的盛装食品的金属软管。由于塑料瓶比玻璃瓶具有生产成本低、运输方便、不易破碎等优点,塑料瓶将取代玻璃瓶;防潮、防氧化、可蒸煮的纤维增强塑料瓶将迅速占领市场。备有易拉盖、儿童安全盖、防盗盖的包装容器也将陆续出现。(摘自《信息时报》)
With the rapid development of modern food industry, there will be great changes in the packaging materials, forms, containers and other aspects of the world’s food. 1. Packaging materials: will be soft, light, saving, convenience and health trends. Light weight and high strength glass, metal, polyester, will replace the traditional glass and metal packaging materials; fiber packaging materials such as cellophane and translucent paper, oil-proof paper, etc., will be oriented polypropylene, high density and Low density film, resin film, etc .; packaging materials will shift from the traditional raw materials to petrochemical raw materials, other packaging materials will be phased out. 2. Packaging: Aseptic packaging will be a symbol of modern packaging. Flexible packaging will rapidly develop and be widely used; component packaging, security and safety packaging will also be further attention; stay, big, stupid, thick, thick old packaging will be lightweight, small package instead; a small amount of fixed Packaging will continue to be welcomed by consumers. In addition, reducing packaging costs will be achieved by improving the performance of packaging materials, rather than by using cheap packaging materials to solve. 3. Packaging containers: Traditional glass bottles and metal bottles will be replaced, the gradual emergence of convenience, to enable the food easy to re-stored food filled metal hose. As plastic bottles than glass bottles with low production costs, easy transportation, not broken, etc., plastic bottles will replace glass bottles; moisture, oxidation, cooking fiber reinforced plastic bottles will quickly capture the market. With easy to pull cover, child safety cover, security lid packaging containers will also be gradually emerged. (From “Information Times”)
