Rui'an Liangcai Machinery Co., Ltd. is located in Rui'an, Zhejiang, renowned as the "Capital of China's Plastic Packaging Machinery Industry." Leveraging the mature plastic machinery industrial cluster in southern Zhejiang, the company is a specialized high-tech manufacturer of plastic packaging machinery, integrating R&D design, complete machine production, sales and trade, after-sales maintenance, and full-plant production line customization. With years of dedicated research and production in the soft packaging industry chain, its core product lines comprehensively cover four major categories: blown film machines, printing machines, bag-making machines, and other customized non-standard machinery, providing one-stop supply of equipment for the entire plastic packaging production chain—from raw material film formation to pattern printing and finished bag production.

Our film blowing equipment ranges from single-layer to multi-layer co-extrusion rotary die head models, compatible with LDPE, HDPE, recycled plastic, PLA/PBAT fully biodegradable raw materials and more. The finished films are widely applied for courier packaging bags, supermarket shopping bags, agricultural mulch film, food wrapping film and stretch film. Fitted with frequency conversion speed control, precise temperature regulating system and automatic film deviation correction, our machines feature stable extrusion output, low energy consumption and uniform film thickness. Available for standalone use or inline connection with subsequent printing and bag-making equipment to build integrated automatic production lines for packaging factories of all sizes.

We supply a complete range of flexographic and gravure printing machines with 1~8 color options and variable working widths, designed for roll film color printing of brand logos, product patterns and surface markings on plastic packaging. Adopting photoelectric automatic color registration, servo feeding and eco-friendly water-based ink printing systems, our printing equipment delivers high printing precision, low ink waste and meets global environmental production standards, suitable for printing on plastic film as well as non-woven fabric rolls for diversified packaging demands.

Our full lineup of bag-making machines covers hot-cut sealing machines, roll garbage bag makers, courier bag perforation machines and self-sealing pouch equipment. Integrated with servo fixed-length cutting, photoelectric tracking sealing, automatic punching and edge scrap recycling functions, these devices efficiently produce courier bags, supermarket vest bags, food flat pouches, fresh-keeping roll bags and resealable bags with neat sealing and accurate cutting dimension. High automation level effectively reduces manual labor cost for mass production and flexible small-batch customized orders.

To satisfy clients’ full-factory setup needs, we also manufacture supporting auxiliary equipment including plastic crushers, pelletizers, film slitter rewinder and edge material recycling machines, covering raw material pre-processing, leftover plastic recycling and film secondary processing. With comprehensive product range, customers can source all required production machines in one place, cutting multiple-supplier procurement costs and communication troubles.

Adhering to the core principle of Superior Craftsmanship, Integrity-based Cooperation & Technology-driven Packaging Development, every finished machine undergoes 72-hour continuous running test with actual raw materials before delivery to guarantee stable on-site operation. We provide full-lifecycle pre-sales, in-sales and after-sales services: free factory layout planning and customized solution design by professional engineers before order confirmation; real-time production progress tracking during manufacturing; overseas on-site installation, commissioning and operator training, plus lifelong spare parts supply and periodic equipment maintenance after shipment.

Benefiting from reliable product quality and considerate after-sales support, Liangcai’s machinery is well-received across all provinces of China and exported to Southeast Asia, Middle East, Africa, South America and dozens of other countries worldwide, establishing long-term stable cooperative partnerships with thousands of packaging manufacturers globally.

Focused on the worldwide green transition of packaging industry, Liangcai Machinery keeps increasing R&D investment on special-purpose machinery for fully biodegradable packaging materials, optimizing the structural design of film blowing, printing and bag making equipment for eco-friendly plastic production. In the long run, we will deepen the R&D of automatic inline production lines and intelligent unmanned workshop equipment, upgrading from a single machinery manufacturer to a global total solution provider for intelligent flexible packaging factories, empowering the green, efficient and intelligent upgrading of global packaging machinery industry with reliable Ruian-made quality.
