生物降解顆粒塑料由于具有良好的降解性，主要用作食物軟硬包裝材料，這也是現(xiàn)階段其較大的應用領域。下面來簡單講解一番吧。

Biodegradable granular plastics are mainly used as soft and hard food packaging materials because of their good degradability, which is also its larger application field at this stage. Let's explain it briefly.

生物降解塑料主要的目標市場是塑料包裝薄膜、農用薄膜、一次性塑料袋和一次性塑料餐具。相比傳統(tǒng)塑料包裝材料，新型降解材料成本稍高。但是隨著環(huán)保意識的增強，人們愿意為保護環(huán)境而使用稍高的新型降解材料，環(huán)保意識的增強給生物降解新材料行業(yè)帶來了巨大的發(fā)展機遇。

The main target markets of biodegradable plastics are plastic packaging film, agricultural film, disposable plastic bags and disposable plastic tableware. Compared with traditional plastic packaging materials, the cost of new degradable materials is slightly higher. However, with the enhancement of environmental awareness, people are willing to use new biodegradable materials with slightly higher prices for environmental protection. The enhancement of environmental awareness has brought great development opportunities to the biodegradable new material industry.

隨著國內經濟的發(fā)展，成功舉辦奧運會、世博會等多項震驚世界的大型活動，各世界文化遺產及風景名勝所在地保護的需要，塑料造成的環(huán)境污染問題愈發(fā)被重視，各級政府已將治理白色污染列為工作之一。

With the development of domestic economy, the successful hosting of the Olympic Games, WorldExpo and many other large-scale activities that shocked the world, the need to protect world cultural heritage and scenic spots, the environmental pollution caused by plastics has been paid more and more attention. Governments at all levels have listed the treatment of white pollution as one of the key tasks.

生物降解材料產品的性能不能完全滿足消費者的需求。雖然市場上有很多品種，但每種材料的力學性能和加工性能僅在一個方面有突出的特點，綜合性能還存在一些不足，這將是制約其市場應用和推廣的瓶頸之一。國內企業(yè)在開發(fā)生物降解材料產品的同時，應注意加快開發(fā)具有自主知識產權的創(chuàng)新產品和用途。

The performance of biodegradable material products can not fully meet the needs of consumers. Although there are many varieties in the market, the mechanical properties and processing properties of each material have outstanding characteristics in only one aspect, and there are still some deficiencies in its comprehensive properties, which will be one of the bottlenecks restricting its market application and promotion. While developing biodegradable material products, domestic enterprises should pay attention to accelerating the development of innovative products and uses with independent intellectual property rights.

由于植物纖維的引入及其在原料中所占比例的增加，生物降解材料的成本可以與傳統(tǒng)塑料競爭，是目前市場上成本低的全生物降解材料；各種植物纖維的物理性能被引入到材料中，使一些材料的性能甚優(yōu)于傳統(tǒng)塑料，如薄膜制品的強度更高，注塑和片材的耐溫性更好等。

Due to the introduction of plant fiber and the increase of its proportion in raw materials, the cost of biodegradable materials can compete with traditional plastics, and they are all biodegradable materials with low cost in the current market; The physical properties of various plant fibers have been introduced into materials, making some materials even better than traditional plastics, such as film products with higher strength, injection molding and sheet materials with better temperature resistance.

生物降解顆粒塑料成型工藝優(yōu)于其他可降解材料。它具有收縮小、不粘、韌性好、強度高、尺寸穩(wěn)定性好、不脆裂的特點。克服了其他可降解材料(如聚乳酸、PBS)不耐高溫的缺點，生物降解塑料的耐溫性可達102-115度，大大提高了生物降解材料的可用性。

The molding process of biodegradable granular plastics is superior to other degradable materials. It has the characteristics of small shrinkage, non stick, good toughness, high strength, good dimensional stability and no embrittlement. It overcomes the shortcomings of other degradable materials (such as polylactic acid, PBS) that are not resistant to high temperature. The temperature resistance of biodegradable plastics can reach 102-115 degrees, which greatly improves the availability of biodegradable materials.
