Kunshan Xinzhenpin New Thin Film Material Technology Co., Ltd.
Established in 2018, Kunshan Xinzhenpin is a specialized manufacturer dedicated to ePTFE waterproof and breathable membrane solutions. We operate a fully integrated production chain covering ePTFE raw membrane manufacturing, composite and post-treatment processing, precision converting, and fully automated assembly of finished venting products. Our manufacturing floor is equipped with advanced equipment including precision rotary die-cutting machines, slitting machines, 2D optical measurement systems, and ultrasonic welding machines, complemented by in-house testing facilities such as air permeability testers and hydrostatic pressure testers. With a current production capacity utilization below 60%, we maintain ample headroom for rapid order fulfillment — our membrane line delivers 3 meters per minute, and vent plug assembly reaches 20,000 units per 8-hour shift per line.
Quality is engineered into every step. All processes are governed by autonomous automated control, and we conduct 100% air permeability testing on finished products to guarantee consistent field performance. Core ePTFE raw materials are imported to secure stable premium quality, while we also offer domestically produced process-grade membranes that deliver reliable performance with superior cost advantages and greater supply flexibility. Our team of 30 includes 6 management professionals and 6 dedicated technical specialists, whose deep expertise is reinforced by a rich portfolio of customized solutions for unique customer applications. This, combined with industry-leading technical reserves, in-house mastery of core treatment technologies, and high levels of production automation, forms the foundation of our distinct cost efficiency.
We hold internationally recognized certifications including IATF 16949, ISO 14001, and GB/T 24001, underscoring our commitment to automotive-grade quality management and environmental responsibility. Our comprehensive product portfolio encompasses vent membranes, vent plugs, vent valves, vent caps, vent gaskets, acoustically transparent membranes, and desiccant components, serving demanding markets such as automotive, new energy, outdoor electronics, and medical devices.

| Production Line: | As a professional manufacturer of expanded PTFE (e-PTFE) functional membranes and finished protective components, we operate a fully integrated production chain covering base film manufacturing, lamination, precision die-cutting, injection molding and final assembly. Our production base is equipped with Class 10,000 clean workshops, high-precision e-PTFE stretching lines, automatic lamination equipment, CNC die-cutting machines and standard injection molding lines, enabling end-to-end production from raw PTFE resin to finished breathable and acoustic components.
Our product portfolio covers pure e-PTFE waterproof breathable films, non-woven/ fabric/ mesh laminated composite membranes, adhesive-backed and weldable breathable die-cuts, acoustic transmission membranes for consumer electronics, PE foam and aluminum foil induction breathable gaskets, HDPE vent plugs, and automotive breathable valves & caps, fully catering to automotive electronics, portable devices, chemical packaging and home appliance sectors.
We implement a strict full-process quality management system in line with ISO 9001 and IATF 16949 standards. Each batch undergoes rigorous testing on air permeability, waterproof rating, temperature resistance, acoustic loss and chemical tolerance, from incoming raw material inspection to finished product outgoing verification. With both large-scale mass production lines and flexible small-batch production capacity, we ensure stable delivery, consistent product performance and reliable quality for global clients.
