Patented Technology: The Core Competitiveness of China’s Plastic Machinery Industry

When packaging manufacturers source plastic forming equipment, more buyers are realizing that price and basic specifications are no longer the only evaluation standards. Independent patented technology, R&D capacity and machine stability have become decisive factors separating outstanding manufacturers from ordinary suppliers.

Generic copied machines often suffer from inconsistent forming quality, high energy consumption, poor adaptability to biodegradable materials and frequent breakdowns. In contrast, original manufacturers with independent intellectual property rights keep optimizing machine structure, servo control systems and forming processes. These upgrades help packaging plants reduce reject rates and boost long-term production efficiency.

A number of high-tech enterprises in China keep investing in R&D and have obtained invention and utility model patents, focusing on thermoforming and cup-making equipment for the booming biodegradable packaging market. Among them, Shantou Longsheng Industrial Co., Ltd. stands out as a reliable original plastic machinery factory with full-line R&D capability and multiple patents.

Shantou Longsheng Industrial: Guangdong High-Tech Enterprise Founded in 1998 with Multiple Patents

Established in 1998 with a registered capital of RMB 10 million, Shantou Longsheng Industrial Co., Ltd. is a certified High-Tech Enterprise in Guangdong Province. After more than 20 years focusing on R&D and manufacturing of plastic packaging machinery, the company holds a number of independent invention patents. Instead of simply copying existing machine designs, Longsheng keeps optimizing mechanical structures, fine-tuning servo systems and developing mould forming processes in-house.

Different from suppliers that only sell single main machines, Longsheng leverages its patented technology to provide turnkey production line solutions. Its product portfolio covers sheet extruders for PET, PP, PE, PS, corn starch and PLA materials, multi-station thermoforming machines, flip mold thermoformers, blister machines, cup making machines, edge curling machines, mixers, auto loaders, robotic handlers, cup stackers, cup counting machines, packaging machines and custom precision moulds. Whether customers produce traditional plastic jelly cups, disposable food containers or eco-friendly packaging made from PLA and corn starch, they can find suitable equipment here.
