China PET bottle flakes production manufacturer introduction

March 01,2023

Polyester PET is mainly used inPET bottle flake making machine, pet bottle to polyester fibre machine and polyester film, divided into polyester filament and polyester staple fiber, accounting for about 75% of the total polyester production. They are mainly used in textile industry: polyester PET bottle flakes making machine,accounts for about 20%, mainly used for food and beverage packaging; polyester film accounts for about 5%, mainly used for outer material, with good printing property.

Bottle PET is an environmentally friendly polymer polyester material. In comparison with glass, metal, paper and other plastic packaging materials, bottle PET has the advantages of safety, high transparency, light material, easy transportation, environmental protection and so on, so it is widely used in a variety of fields.
Polyester bottle sheet usually refers to the polymerization production of polyester raw materials generally processed into about 452 mm sheet particles. Polyester production process route includes direct esterification (PTA) and transesterification (DMT). The technical path of the mainstream chemical reaction in the domestic PET industry is the PTA method, and the two-step synthesis process has been relatively mature. The bottle level PET production industry of Chinese Wankai New Material, China Resources Materials and other enterprises belongs to the two-step synthesis process of polyester process + solid phase shrinkage and cohesion process (CP + SSP).

According to statistics, in 2022, the Chinese production capacity of polyester bottle sheet is 12.99 million tons, with a year-on-year growth of 3.59%. In 2022, the net production capacity of polyester bottle piece is 450,000 tons, among which the new production capacity is 600,000 tons of Chongqing Wankai. By 2022, there are 16 bottle-level PET enterprises in China, with a total production capacity of 12.7 million tons / year. Among them, there are 5 enterprises with a production capacity of more than 1 million tons, namely Wkai New Material, Hainan Yisheng,SANFAME, China Resources Materials and Jiangyin Chenggao (Jiangyin Chenggao 1.2 million tons PET bottle flakes machine has been transferred to China Resources due to bankruptcy).

The following are a few PET bottle flakes making machine companies introduced, ranking in no particular order.
