As a globally recognized plastic recycling machine manufacturer specializing in waste plastic recycling equipment and industrial polymer dryers since 1998, ZHANGJIAGANG LIANDA MACHINERY CO., LTD has established an unshakeable benchmark for excellence. We design our advanced systems to deliver simplicity, stability, and maximum production uptime for high-volume plastic producers and professional recyclers worldwide.
With over 2,680 successfully operational machines installed across 80 countries—including Germany, the United Kingdom, Mexico, Russia, the United States, South Korea, Thailand, Japan, Spain, Hungary, Colombia, Pakistan, and Ukraine—our engineering prowess is proven across diverse industrial ecosystems and environmental regulatory standards.
Navigating global plastic waste streams requires robust, intuitive machinery. Our core mission is to strip away mechanical complexity while optimizing thermal efficiency. Whether processing post-consumer PET bottles, agricultural films, or engineering resins, Lianda provides turnkey solutions that safeguard product integrity and maximize return on investment.
The global packaging and recycling ecosystem is undergoing a seismic shift driven by circular economy mandates, stringent carbon footprint caps, and rising consumer demand for food-grade recycled content (rPET). Procurement directors and plant managers in major manufacturing hubs are under intense pressure to upgrade their extrusion lines to handle variable feedstock quality without sacrificing line speed.
Modern extrusion plants cannot rely on legacy thermal technology. By integrating proprietary infrared rotary drying and solid-state polycondensation (SSP) capabilities, Lianda bridges the gap between raw post-consumer waste and high-spec bottle-to-bottle manufacturing requirements, meeting FDA and EFSA direct food contact criteria.
Quality assurance is embedded in every phase of our manufacturing workflow. Backed by rigorous international standards, Lianda Machinery operates under certified quality management systems:
Our dedicated research and design team continuously pioneers technological milestones that redefine industry benchmarks:
Stable Operation. Maximum Performance. Minimum Consumption.
Traditional dehumidifying dryers require 4 to 6 hours of drying time and consume massive amounts of electrical energy. Lianda's Infrared Rotary Dryer (IRD) utilizes direct infrared thermal penetration, reducing crystallization and drying time to just 20 minutes while achieving moisture levels below 50 ppm, cutting operational energy costs by 45% to 50%.
Yes. Our CE-certified IR-Safe flake decontamination systems are engineered specifically for direct food contact packaging applications (bottle-to-bottle grade), complying with stringent global food safety and migration testing regulations.
With installations across 80 countries since 1998, Lianda provides turnkey project support—including custom engineering layout, on-site or remote installation guidance, operator training, and lifetime technical assistance tailored to local electrical and safety compliances.
Absolutely. Our patented thermal and extrusion systems are optimized for a wide spectrum of engineering polymers, including PETG, PLA, PBAT, TPEE, PPSU, PEI, PPS, and PBS, ensuring high molecular weight retention and melt stability.
