Generally, it is the blend of modified starch and biodegradable polyester (such as PLA / PBAT / PBS / PHA / PPC). It can be completely biodegradable, compostable and pollution-free to the environment. The waste is suitable for composting, landfill and other treatment methods. Starch based bio based plastics are generally a mixture of modified starch and polyolefins (such as PP / PE / PS).

它的環保意義在于能夠減少石化資源的使用，減少二氧化碳排放，廢棄物適合焚燒處理。

Its environmental significance is to reduce the use of petrochemical resources, reduce carbon dioxide emissions, and waste is suitable for incineration.

這兩種材料都可以代替傳統石油基塑料，廣泛用于塑料包裝材料、防震材料、塑料膜及塑料袋、一次性餐飲具、食品容器、玩具等。

These two materials can replace traditional petroleum based plastics and are widely used in plastic packaging materials, shockproof materials, plastic films and plastic bags, disposable tableware, food containers, toys and so on.

與傳統塑料制品相比，淀粉基材料及制品的優勢表現

Compared with traditional plastic products, starch based materials and products have advantages

1、性能相近：具有與同類傳統塑料制品相同和相近的使用性能；

1. Similar performance: it has the same and similar performance with similar traditional plastic products;

2、環保：淀粉基生物基塑料及制品具有節約石油資源、減少二氧化碳排放的優勢；淀粉基生物降解塑料及制品具有完全生物降解、可堆肥，實現垃圾無害化處理的優勢；

2. Environmental protection: starch based bio based plastics and products have the advantages of saving oil resources and reducing carbon dioxide emissions; Starch based biodegradable plastics and products have the advantages of complete biodegradation, compostability and harmless waste treatment;

3、：淀粉基材料及制品不含塑化劑、雙酚 A 、重金屬等有毒有害物質。食品級材料符合國內外食品級塑料相關標準要求；

3. Safety: starch based materials and products do not contain plasticizer, bisphenol A, heavy metals and other toxic and harmful substances. Food grade materials meet the requirements of relevant standards of food grade plastics at home and abroad;

4、生產工藝：生產過程無三廢排放，不會對環境造成新的污染；

4. Production process: there is no discharge of three wastes in the production process, which will not cause new pollution to the environment;

5、成本：淀粉基生物基塑料料及制品與普通石油塑料制品持平，淀粉基全生物降解材料及制品的成本約是普通石油塑料的兩倍。

5. Cost: the cost of starch based bio based plastics and products is the same as that of ordinary petroleum plastics. The cost of starch based fully biodegradable materials and products is about twice that of ordinary petroleum plastics.
