Global PET-Based Copper Foil Market Strategic Research Report

Scope of the Report

The global PET-Based Copper Foil market size is predicted to grow from US$ 205 million in 2025 to US$ 1,763 million in 2032; it is expected to grow at a CAGR of 36.3% from 2026 to 2032.

PET-Based Copper Foil is an advanced current collector material that integrates a lightweight polymer substrate with ultra-thin copper layers through vacuum deposition technology. By combining a polymer base film with conductive copper coatings, the material significantly reduces weight while maintaining excellent electrical conductivity and mechanical stability. Its advantages include improved battery safety, reduced material consumption, enhanced energy density, and strong flexibility for next-generation battery structures. The capacity utilization rate in 2025 reached 70%, and the industry’s average gross margin was approximately 29%. Production in 2025 was 79.25 million sqm at an average price of 2.65 USD per sqm. The upstream segment mainly consists of PET base films, copper sputtering targets, and magnetron sputtering equipment, with representative suppliers including Jiangsu Shuangxing, Wanhua Chemical, GRINM Advanced Materials, and Dongwei Technology. The midstream focuses on composite current collector manufacturing processes such as base film surface treatment, magnetron sputtering copper deposition, multilayer structure formation, and quality control to ensure conductivity, adhesion, and mechanical strength. Downstream applications are primarily in power batteries and consumer electronics batteries, with key customers including Tesla, CATL, BYD, Samsung SDI, and LG Energy Solution.

Global key PET-Based Copper Foil players cover Baoming Technology, Chongqing Jinmei New Materials, Enlion Co., Ltd., Shuangxing New Material, Wanshun New Material, etc.
