1拉丝，烧着的时候在打火机上拉一下丝，看丝拉的长不长，然后把拉出来的丝拉断，看中间的断点，丝是不是卷成小圈状，卷的越多说明熔点高。不过一般如果是瓶片，应该都不会有什么大问题。

    2先闻味道，PET塑料的味道不同于一般塑料，用打火机烧一下，纯的PET塑料会散发出非常芳香的味道，如果PET塑料里含有其他成分，味道就很刺鼻。有种瓶子里面含有SEBS的成分就不能用。专业塑料知识交流微信群加小编微信：NB58250988

    3看烧起来的部分，如果过分发黑或者油滴的很快，多数熔点不正常，这在PET塑料薄膜片中常有。

    4最关键的一点是分辨其中是否含有PET塑料，这可是PET的致命伤。首先多取样，然后平铺在阳光充足的地方，PVC在阳光下呈淡蓝色。如果对折当中会有白色的折痕。以上是肉眼鉴别，准确性有限，主要看经验

昨日市场价格僵持运行，部分小幅走软，PTA期货虽小涨，但对行情提振有限，部分瓶片企业下调出厂价，货源成本支撑作用减弱，下游随用随购，市场价格参考：华东地区水瓶料报7100-7300元/吨自提，商谈7000-7200元/吨，华南地区水瓶料报7200-7300元/吨短送，商谈7100-7250元/吨。

The world is inseparable from the chemical materials, 92 percent of the material are synthetic materials, "which is the International Chemical Manufacturers Association (AICM), Saudi Basic Industries, vice president and president of North Asia Li Lei in 6 Speaking at the AICM Media Workshop on March 2, we also have a clear understanding of the importance and status of synthetic materials in applications.

    On the occasion of the World Environment Day on June 5, AICM organized the first media workshop this year, with the "plastic story" as the main line, and made an in-depth interpretation of the innovation and sustainable development of the plastics industry. The International Association of Chemical Manufacturers (AICM) currently represents more than 50 multinational chemical companies with significant investments in China. The membership business covers all aspects of chemical manufacturing, transportation, distribution and disposal. The event was supported by Saudi Basic Industries, Kesi Chuang, DSM, LANXESS, Kemira and Keith's six member companies.

    "As the plastic has the characteristics of low energy consumption, easy processing, light weight, recyclable and so on, it makes plastic," says Qiu Weihui, vice president of polycarbonate business in mainland China and Hong Kong. The new Boeing 787 fuselage made of three plastic composite materials, the characteristics of the light quality of the plastic material, the new material of the new Boeing 787 is made of three plastic composite materials, Will contribute to fuel combustion by 20%.

    In the plastic innovation, DSM Engineering Plastics Business Unit Greater China Business Director Zhang Zhenyu introduced the characteristics of the new plastic, that is easy to shape, chemical resistance, high temperature and high toughness, and even can become a substitute for metal materials.

    The vigorous development of the plastics industry is bound to be accompanied by widespread concern about the pollution problem. Plastic is widely used for its low cost and practicality. According to the relevant statistics, only a plastic bag is a plastic product, and more than 200 per capita is used per year. Landfill, which takes 100 to 400 years to degrade. The disposal of plastic waste makes plastic products controversial. So how to solve the problem of plastic pollution, so that plastic on the sustainable development of the environment play a positive role is practitioners are currently facing the biggest challenge. "New plastics economy" is the plastics industry in the circular economy theory based on the exploration of a new concept, that is, through the design of recovery and regeneration of industrial systems to achieve the sustainable development of the plastics industry. The three main objectives of the new plastics economy are: 1. To improve the recovery and recycling of plastics and to promote economic and absorbability, to create an effective plastic economy; 2. To significantly reduce the penetration of plastic to nature Systems (especially the ocean) and other negative extensions. 3. To reduce the risk of recycling and non-materialization, to explore and use renewable raw materials, and gradually separate the plastic and fossil raw materials.

    Scientists have developed biodegradable plastic films that can prevent contamination of the soil and contain bio-based plastic materials. And found a body containing polyethylene decomposition enzyme worms, this discovery will help humans beat plastic waste. According to a recent report, Plastics and Sustainable Development: Environmental Benefits, Cost Valuation and Opportunities for Continuous Improvement, the environmental costs of using plastics in consumer and packaging are four times lower than the environmental costs of using alternative materials. The above research and discovery can be regarded as plastic in the sustainable development of considerable kinetic energy. Through the continuous development of the plastics industry and its contribution to sustainable development and the contribution, I believe that the future of plastic will be the first to become environmentally friendly, practical, economical and efficient processing and manufacturing materials.
