Recently, domestic protective film manufacturers have ramped up investment in formula and process R&D, achieving technical upgrades for high‑end protective films used in electronic displays, new‑energy industries, hardware and plastic processing sectors. Multiple new anti‑static, low‑residue‑adhesive and high‑low‑temperature‑resistant products have passed performance verification, further advancing the localization of functional protective films.
Driven by the rapid growth of high‑end domestic manufacturing, downstream clients impose stricter requirements on protective films, with zero‑residue peeling, low crystal‑point density, stable weather resistance and high cleanliness becoming critical standards. For a long time, many high‑end application scenarios relied heavily on imported film materials. R&D teams have focused on three core areas: pressure‑sensitive‑adhesive formulation, substrate selection and coating‑process optimization. By optimizing the molecular structure of adhesives and upgrading dust‑free coating production procedures, common‑industry pain points such as adhesive residue, edge warping and high‑temperature failure have been effectively addressed.
According to the company’s technical lead, the newly‑optimized product portfolio covers PE and PET‑based protective films. These films are suitable for protection during processing and transportation of display modules, lithium‑battery components, metal sheets and plastic housings. Adhesion strength can be customized on demand. The products have passed multiple SGS tests for aging resistance and peeling performance, with overall properties comparable to imported equivalents.
“Though protective films are auxiliary consumables, they directly determine finished‑product yield,” said the company executive. Moving forward, the enterprise will keep focusing on pain points across segmented industries and increase R&D spending. It aims to deliver cost‑effective, customizable protective‑film solutions for domestic manufacturers, lower supply‑chain costs and support independent and controllable development of the industrial chain.
