Suwang Packaging Technology Co., Ltd. was established in 2014, with its headquarters located in the "No. 1 Town of China's Plastic Woven Industry" – the birthplace of China's plastic woven bag sector. Its subsidiary, Wenzhou Pinhao Packaging Co., Ltd. (founded in 2016), is situated in the Cangnan County Demonstration Industrial Park, Wenzhou City. Leveraging the cluster advantages of the world's largest production base for plastic woven products, it has built a comprehensive industrial ecosystem integrating R&D, design, production, and sales of intelligent plastic packaging. The company is committed to becoming a global leader in providing specialized functional packaging solutions.

● Full Industrial Chain Intelligent Manufacturing Capability

   Starting from the production of basic woven bag tubular materials, we have now expanded into nine core technology areas, including BOPP color printing, laminated film coating, valve pocket forming, and eco-friendly hot-melt sealing at the bottom, forming a one-stop service system of "production + post-processing".

   Equipped with fully automated production lines and intelligent inspection systems, we achieve full-process quality control from raw materials to finished products, and have obtained five international authoritative certifications, including the ISO9001 Quality Management System.

● Leading the Industry in Innovative R&D

   As a national-level high-tech enterprise, we have accumulated 2 invention patents and 18 utility model patents. We have taken the lead in formulating group standards such as "Plastic Woven Bags for Food/Fertilizer Use", filling the gaps in industry norms.

   We have launched an industry-first "Green Intelligent Manufacturing" product matrix: anti-slip and wear-resistant bags, antistatic packaging, high-temperature-resistant (150℃+) bags, and leak-proof, lightweight, and eco-friendly bags (with a 30% reduction in thickness and a 60% increase in recyclability), helping customers achieve energy conservation, emission reduction, and ESG goals.

Our products, characterized by features such as sun-resistant and damage-resistant properties, high tensile strength, environmental friendliness, and recyclability, are widely applied in over 20 fields including petrochemicals, new chemical materials, food, and grain & oil industries. We serve the top 50 Asian enterprises and listed companies:

✅ Strategic partner of China Lesso Group for 20 consecutive years

✅ Long-term supplier to industry leaders such as Sinopec Group, Formosa Plastics Corporation, and Wuhan Jinniu Pipe Industry Co., Ltd.

✅ Our products reach end-users in high-value-added scenarios, including new energy materials (Ningbo Nengzhiguang) and food-grade packaging (Bangzhong Polymer).

With the mission of "Setting Standards for Plastics, Packaging the Future," our company continues to deepen the integration of informatization and industrialization (certified by GB/T23001), driving the upgrading of the packaging industry through technological innovation. In the future, we will focus on cutting-edge fields such as biodegradable materials and digital anti-counterfeiting packaging, striving to achieve a leapfrog development from "Made in China" to a global brand, and providing smarter, more sustainable packaging solutions for customers worldwide!
