For mass production of garbage bags, supermarket storage bags, and industrial packing bags, cost reduction and efficiency improvement, as well as diversified finished products, have always been the core demands of manufacturers. Traditional roll bag making machines with paper cores incur high consumable costs and involve cumbersome paper core removal procedures in post-production, while ordinary models fail to meet customized requirements such as expandable bottom gussets and automatic labeling for finished bags. Specializing in one-stop packaging solutions, Wenzhou Chenqi Machinery launches the CQCS-800/1000 coreless drawstring roll bag making machine for global clients to address market pain points. This machine is specially developed for coreless rolled drawstring bags, integrating side sealing, bottom sealing, pre-perforation, bottom gusset forming, and drawstring threading into one integrated molding process. An optional fully automatic labeling unit is available to resolve all challenges of bag forming, winding, and labeling in one production line, making it the preferred equipment for medium and small packaging factories as well as large plastic product enterprises to upgrade their production lines.
Core Advantage: Coreless Winding Design to Cut Production Costs from the Source
Both CQCS-800 and CQCS-1000 models adopt coreless winding molding technology. No paper tube or paper core is required for winding throughout production, yielding finished rolled drawstring bags made purely of plastic film. On one hand, it eliminates long-term consumable expenses on paper core procurement and storage, saving 10% to 18% auxiliary material costs in mass long-term production. On the other hand, finished rolls are tighter and neater, facilitating easier loading, unloading, storage, and terminal packaging. It also cuts labor costs by removing the manual paper core removal process and streamlines post-production assembly lines. Equipped with a dual servo feeding control system, the machine delivers constant feeding tension without film stretching. Compatible with mainstream raw materials including LDPE, HDPE, and fully biodegradable plastic films, it produces flat seals and uniform perforations even for thin films, maintaining a high yield rate under high-speed operation.
Unique Craftsmanship: Integrated Precision Gusset Folding for Multi-Scenario Multi-Purpose Bags
Fitted with an integrated precision bottom gusset folding mechanism, the machine forms W-shaped bottom gussets on line without secondary post-processing. Drawstring bags with bottom gussets feature enhanced expandable capacity, higher load-bearing capacity, and larger storage volume, perfectly suited for manufacturing thick kitchen waste bags, supermarket bulk storage bags, pet poop bags, and industrial waste bags. The bag width can be flexibly adjusted. The exclusive folding technology of CQCS-800/1000 supports mass production of narrow-width bags as well as customized large wide-size bags. A single machine handles multiple bag specifications without replacing the main unit, maximizing equipment versatility and optimizing factory equipment investment returns.
Upgradable Optional Accessory: Linked Automatic Labeling Machine to Boost Product Added Value
To meet the demand for branded packaging production, the CQCS-800/1000 reserves complete expansion stations for direct installation of an optional automatic labeling machine. It realizes synchronous on-line bag forming, drawstring threading, gusset folding, labeling and winding. The on-line labeling system ensures precise positioning for attaching logo labels, specification labels and environmental protection marks. Finished bags can be directly delivered to market without outsourced labeling, shortening order delivery cycles. The labeling unit is linked to the main unit PLC system with synchronized running speed to avoid production downtime, balancing high production efficiency and attractive finished bag appearance. It helps clients develop differentiated products and raise market pricing and competitiveness.
Stable Electrical Control Configuration, Long Service Life & Easy Maintenance
The whole machine adopts PLC microcomputer + Weinview touch screen intelligent control interface with visualized one-click parameter setting. Digital fine-tuning is available for bag length, running speed, sealing temperature, and gusset dimensions, enabling new operators to operate proficiently after simple training. Equipped with an imported photoelectric tracking device, it achieves accurate mark tracking for both printed color bags and plain white bags. Complete safety protection mechanisms are installed: the machine will automatically stop and trigger alarms in case of film breakage, material jamming, abnormal temperature, or reaching preset production counts to avoid equipment damage and losses. Key transmission components are made of wear-resistant alloy with a robust overall structure, delivering low failure rates during long non-stop operation. Chenqi Machinery provides full after-sales services including on-site installation and commissioning, lifelong technical support and fast spare parts supply, with localized technical docking available for overseas clients.
Applicable Industries & Finished Product Range
The machine mainly produces coreless rolled drawstring garbage bags with bottom gussets, widely applied in household daily use, hotel property management, supermarket retail, catering back kitchens, factory sanitation and pet supplies. Compatible with ordinary plastic films and biodegradable eco-films, it aligns with the global trend of eco-friendly packaging. It suits both small- and medium-batch orders and high-speed mass production for large factories. Customized supporting solutions can be tailored according to clients’ workshop space and production capacity targets.
