生物降解颗粒塑料由于具有良好的降解性，主要用作食物软硬包装材料，这也是现阶段其较大的应用领域。下面来简单讲解一番吧。

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标市场是塑料包装薄膜、农用薄膜、一次性塑料袋和一次性塑料餐具。相比传统塑料包装材料，新型降解材料成本稍高。但是随着环保意识的增强，人们愿意为保护环境而使用稍高的新型降解材料，环保意识的增强给生物降解新材料行业带来了巨大的发展机遇。

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.

随着国内经济的发展，成功举办奥运会、世博会等多项震惊世界的大型活动，各世界文化遗产及风景名胜所在地保护的需要，塑料造成的环境污染问题愈发被重视，各级政府已将治理白色污染列为工作之一。

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.

生物降解材料产品的性能不能完全满足消费者的需求。虽然市场上有很多品种，但每种材料的力学性能和加工性能仅在一个方面有突出的特点，综合性能还存在一些不足，这将是制约其市场应用和推广的瓶颈之一。国内企业在开发生物降解材料产品的同时，应注意加快开发具有自主知识产权的创新产品和用途。

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.

由于植物纤维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与传统塑料竞争，是目前市场上成本低的全生物降解材料；各种植物纤维的物理性能被引入到材料中，使一些材料的性能甚优于传统塑料，如薄膜制品的强度更高，注塑和片材的耐温性更好等。

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.

生物降解颗粒塑料成型工艺优于其他可降解材料。它具有收缩小、不粘、韧性好、强度高、尺寸稳定性好、不脆裂的特点。克服了其他可降解材料(如聚乳酸、PBS)不耐高温的缺点，生物降解塑料的耐温性可达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.
