OEM Plastic Lunch Box Manufacturer for Global Brands
Co-Mold Mould Co., LTD

Drawing from our roots as a plastic mold manufacturer, we possess deep expertise in plastic engineering. While leak-proofing remains a common challenge in compartmentalized food containers, we dedicated ourselves to solving it from the ground up. Through persistent research, we have developed and patented a unique technology that ensures 100% leak-proof performance between every compartment.
As a core driver of our company, our strong R&D capabilities enable us to launch 3-4 new products yearly, all with self-developed molds. To date, we have built a portfolio of over 50 distinctive lunch box products. Supporting this innovation is our R&D team—made up of product and structural designers who hold international honors like the German Red Dot Design Award and American IDEA.
