WENZHOU SHUYOU PACKAGING CO., LTD. is a leading manufacturer of customized laminated bags and insulated solutions for commercial and industrial food delivery. Founded in 2008 (formerly Wenzhou Ruigang Bag Co., Ltd.), the company has over 18 years of OEM/ODM experience in producing non-woven laminated bags, RPET laminated bags, PP laminated bags, cooler bags, drawstring bags, cotton tote bags, and flexible packaging solutions.
Our 6,000 m² production facility houses six gravure printing machines, three laminators, five cutting machines, and more than 80 sewing machines, enabling high-volume production with competitive pricing. For smaller or custom orders, we provide HP Indigo and UV digital printing, allowing fast design updates, high-resolution photo printing, and no plate cost, ideal for branded promotional or specialized bags.
With over 150 employees, including 20+ designers, we provide end-to-end support from concept design to mass production. Each bag undergoes rigorous quality assurance, including thermal retention testing, seam and drop tests, puncture resistance, and repeated opening/closing cycles, ensuring reliability for frequent commercial use.
Sustainability is a core focus: we offer bags made from recycled polyester (rPET), PFC-free water-resistant coatings, and recyclable insulation foams, aligning with global environmental standards without compromising thermal efficiency. Food safety certifications, including FDA and LFGB, guarantee safe contact with fresh, frozen, and hot foods, as well as beverages.
Customization is a hallmark of our service. Clients can specify bag dimensions, insulation thickness, closures, handle types, compartments, modular inserts, and branding methods such as screen printing, gravure, digital printing, embroidery, or heat transfer. Additional features such as zippers, piping, internal partitions, and pockets are available to meet operational requirements.
Serving markets in North America, South America, Europe, and Asia, WENZHOU SHUYOU PACKAGING delivers reliable, durable, and efficient insulated solutions. With fast delivery, 100% inspection, free sample provision, and 24/7 customer support, our insulated bags enhance operational efficiency, maintain product integrity, and provide scalable branding solutions for food delivery, catering, and cold chain logistics companies worldwide.
