  生物降解材料用途广泛,可完整生物降解塑料原料及其制品,制品包括淀粉基全生物降解购物袋、连卷袋、平口袋、高性能生物降解保鲜袋、高淀粉含量的生物降解城市垃圾分类袋、生物基可降解快递袋、水溶性洗涤用包装袋、农用地膜、工业用包装袋、电子产品类包装袋、一次性快餐具、饮料瓶杯等制品。这些产品取材于玉米、木薯等天然植物,其中生物含量均大于总数的一半,较快在90天内可实现完整降解。

  Biodegradable materials are widely used and can be used as complete biodegradable plastic materials and products. Products include starch-based full biodegradable shopping bags, roll-up bags, flat bags, high-performance biodegradable fresh-keeping bags, high starch content biodegradable municipal garbage sorting bags, biodegradable express bags, water-soluble washing packaging bags, agricultural film, industrial packaging bags, electronic products. Such products as packaging bags, disposable snack utensils, beverage bottles and cups. These products are derived from natural plants such as maize and cassava, in which the biological content is more than half of the total, and can be degraded completely within 90 days.

  生物降解材料绿色环保带领者,淀粉基生物降解塑料,是淀粉经过改性、接枝反应后与其他聚合物共混加工而成的一种塑料产品,在工业上可以代替一般通用塑料等,可以用作包装材料,防震材料,地膜,食品容器,玩具等。淀粉的性质与淀粉的相对分子质量、支链长度以及直链淀粉和支链淀粉的比例有关。实验证明,高直链含量的淀粉更适合于制备塑料,所得制品具有较好的机械性能目前淀粉塑料的力学性能已经基本达到传统塑料的标准,但因淀粉本身具有吸水性,所以在潮湿环境中材料会吸水导致力学性能严重下降,且淀粉含量越高,问题越严重,有些淀粉塑料甚至能全部溶与水。
  Starch-based biodegradable plastics, a green environmental leader, is a kind of plastic product made by blending starch with other polymers after modification and grafting reaction. It can replace general plastics in industry, and can be used as packaging materials, shockproof materials, plastic film, food containers, toys and so on. The properties of starch are related to the relative molecular weight of starch, the length of amylopectin and the ratio of amylose to amylopectin. Experiments show that starch with high amylose content is more suitable for preparing plastics. The products obtained have better mechanical properties. At present, the mechanical properties of starch plastics have basically reached the standard of traditional plastics. However, because starch itself has water absorption, the material will absorb water in wet environment, which will lead to a serious decline in mechanical properties. The higher the starch content, the more serious the problem is. Some starch plastics It can even dissolve completely with water.
  淀粉生物降解材料,热塑性淀粉塑料生成及应用 除了用作新型可降解材料,淀粉经过一定的处理,在纺织、医药、速冻食品、造纸、建材等行业也得到了较好的应用。因此淀粉生产行业是当前发展前景较好、市场需求较大的行业之一。目前国内生产淀粉的设备也比较成熟,可以做到从原料输送到成品包装全自动化生产。
  Starch biodegradable materials and thermoplastic starch plastics are not only used as new degradable materials, but also used in textile, medicine, quick-frozen food, papermaking, building materials and other industries. Therefore, starch production industry is one of the industries with good development prospects and large market demand. At present, the domestic equipment for starch production is relatively mature, which can be fully automated from raw material delivery to finished product packaging.
