Chinese PET Resin Market Overview
Ⅰ. Top 10 PET Resin Manufacturers in China
Note: The list is generally in on specific order.
Ⅱ. Company Profiles and Industry Capacity Insights
Hengli Group
Hengli Group, founded in 1994. What started was a small textile mill in Dalian. Now it is one of the largest polyester and petrochemical groups in the world. From the date it built, Hengli Group has over 230,000 employees and its revenue in 2024 was approximately RMB 871.5 billion. Hengli is best known for building a complete chain from crude oil refining from PTA to PET. Today, Hengli has become a global benchmark in polyester innovation. Many buyers I've met in the market actually put Hengli on their shortlist — mostly because of its consistent PET quality and strong after-sales support.

Wankai New Materials
If you're in the bottled drink business, you'll probably hear Wankai's name more than once. Wankai New Materials was founded in 2008. In just over a decade, Wankai has built modern production bases in Zhejiang and Chongqing.
The company's main product is bottle-grade PET (widely used in packaging for beverages, cooking oils, condiments, etc.). Its annual PET resin production capacity reaches 3 million tons. Used just about fifteen years, Wankai jumped to No. 2 in China — that's pretty insane speed in this industry. If your end product is food-grade plastic bottles, Wankai undoubtedly has a significant advantage in this field.

Jiangsu Sanfangxiang Group
Sanfangxiang, I guess the name is quite well-known to every packaging converter in Asia. It has decades of experience linking PTA, PET, fiber, and film under one roof.
Its continuous polymerization lines reach about 2 million tons annually, supported by stable PTA feedstock.
The group's long-term partnerships with beverage packaging companies. That's why people in the packaging field still mention Sanfangxiang when they talk about reliable PET.

Hengyi Group
Hengyi is a large‑scale enterprise producing PTA and PET chips. The news reports that Hainan Yisheng has an annual production capacity of about 4.6 million tons of PTA and 3.8 million tons of PET chips.
Earlier data mention a PTA input of 2.1 million tons and PET resin project of 1 million tons per year.
Hengyi also invested equipments (e.g., RTO installations) supporting its scale.
Thus Yisheng stands out for large PET chip/resin capacity on a dedicated basis. For big projects that need good and stable PET chips, Hengyi is a good choice.

Tongkun Group
Known best for polyester filaments, Tongkun also holds vast polymerization assets that produce PET. It's funny that — Tongkun started with fibers, but that background actually helps in PET packaging too.
Its have more than 20,000 employees and the property over RMB 40 billion.
Tongkun might not publish PET data separately. Still, with a 13 million-ton polyester system, you can guess how strong their PET chip polymer is. If your business connects textiles with PET packaging, Tongkun has a natural advantage.

Zhongtai Group
Zhongtai's headquarters in Xinjiang, they can achieve many raw materials and energy that many coastal producers can not.
The company operates around 1.2 million tons of PTA and continues to expand its PET and viscose fiber business.
Its chemical base helps maintain a cost advantage in western China's growing polymer market. I recommend Zhongtai for buyers who prioritize cost efficiency and steady inland supply without lower quality.

Henan GP Chemicals
Henan GP Chemicals supplies PET resin along with a range of thermoplastics for packaging and film applications. Their PET specifications, including intrinsic viscosity and color difference,
Indicate GP Chemicals have the ability of industrial-scale production of PET chips.
Even if the public information of the PET resin is limited. However, the reliability of this company deserves recognition.
If you need a solid mid-tier supplier — not huge, but dependable if you need flexibility.

If you want high quality surprises in supply chain of PET chips, it doesn't get more secure than Sinopec. After all who doesn't heard about Sinopec?

Shanghai Qishen Plastic
Qishen Plastic is recognized in supplier directories as a manufacturer of bottle-grade PET resin/film. Even if limited publicly available capacity or employee data shows, its visibility among bottle-grade resin suppliers and presence in trade databases support its ranking among the top ten. It can be considered as one of the suppliers to consider.

Hebei Changsheng Plastic
Hebei Changsheng — a regional PET resin manufacturer with a focus on custom orders and fast delivery. It is listed among trusted suppliers of bottle‑grade PET resin.
It may not boast million-ton capacity, but its quick response and short lead times make it a favorite among northern Chinese clients who value flexibility over scale. What I like is their speed. Some big names take days; Changsheng usually answers the same day. Especially when we have a new project that require long term adjustment, so I think it is worthy to try.
