Chenqi has independently developed and holds numerous core utility model patents, including tension-free sealing and bagging technology, adaptive anti-static perforation technology, and core-less fully automatic non-stop roll change technology. It is one of the few bag-making equipment manufacturers in the industry with independent core R&D capabilities.
Small batch, multi-SKU production demands quick changeover and versatile capability. Our multifunctional bag making machines with 15-30 minute changeover between bag types are ideal for converters handling diverse customer orders.
High-volume production of Vest bags and shopping bags demands speed, consistency, and cost efficiency. Our vest bag making machines with dual-lane production up to 360 bags/min and automatic waste removal deliver the throughput retail supply chains require.
Chemical bags, FIBC liners, heavy-duty garbage bags, and industrial packaging demand thick films (0.08-0.3mm) with strong, leak-proof seals. Our heavy-duty bag making machines with servo flying knife + resistance wire fusion cutting are purpose-built for rugged industrial applications.
CHENQI bag making machines are built with full servo control, multi-zone PID temperature control, and tension-free sealing technology – delivering superior speed, precision, and reliability across all bag types.
Our bag making machines produce Vest bags, flat bags, heavy-duty bags, rolling bags (core/coreless), courier bags with adhesive tape, multifunctional bags, and disposable gloves – covering all standard plastic bag applications in the market.
Our machines handle LDPE, HDPE, PP, biodegradable (PLA/PBAT), and composite films from 0.005mm to 0.3mm thickness – from ultra-thin gloves to heavy-duty industrial bags.
Up to 360 bags/min for Vest bags (dual-lane), 180 bags/min for standard bags, and high-speed continuous production for rolling bags with non-stop roll change – minimal downtime.
Yes. Our coreless rolling bag machines feature patented automatic non-stop roll change – 24/7 continuous production without manual roll change, saving 12%+ in production costs and eliminating downtime.
Our machines feature multi-zone PID temperature control (±1°C) and tension-free sealing technology for strong, leak-proof seals. Heavy-duty models use servo flying knife + resistance wire fusion cutting for thick films (0.08-0.3mm).
