Fully Automatic Bottom Sealing Bag Making Machine By Flying Knife System+ Hot Slitting With Side Gusset

This combination is the core of our high-speed, high-quality production philosophy. The Flying Knife System allows for continuous motion cutting, eliminating the speed limitations of stop-and-start systems, which dramatically boosts your output. Immediately following, the Hot Slitting technology seals the cut edges of the side gussets with precision heat. This simultaneous cutting and sealing prevents the woven or laminated layers from fraying or delaminating, resulting in a clean, professional, and durable bag edge. It solves the common problems of messy edges and reduced production speed in one integrated process.

Yes, achieving perfectly flat side gussets is a key strength of our design. CHOVYPLAS machines incorporate a precision gusset folding system with adjustable tension control and heated creasing options (on specific models). This ensures the gusset folds are sharp and defined. Furthermore, the synchronized sealing jaws apply uniform heat and pressure, preventing air traps and material distortion that cause unsightly wrinkling or bubbling. This guarantees a premium-quality flat bag that stacks neatly and presents beautifully for your end customers.

The CHOVYPLAS Fully Automatic Bottom Sealing Bag Making Machine is engineered to handle a wide range of materials, from standard LDPE to more demanding ones. It excels particularly in producing heavy-duty bags and robust laminated materials such as woven PP (Polypropylene), CPP, OPP, and kraft paper composites. The powerful pulling system, robust sealing jaws, and consistent heat control are specifically calibrated to create strong, reliable seals and precise cuts through these multi-layer structures.

We've prioritized operational agility. Changing bag sizes, including the side gusset width, is a remarkably streamlined process. Our machine features a modular design with hand-wheel adjustments and digital counters for key parameters like bag length and gusset width. Operators can make most changes without needing special tools, significantly reducing downtime between production runs. This makes the CHOVYPLAS machine ideal for manufacturers who need to frequently switch orders and produce small to medium batches profitably.

Beyond the advanced Flying Knife System and Hot Slitting technology, CHOVYPLAS builds its reputation on reliability and support. Our machines are constructed with premium, wear-resistant components to ensure stability in 24/7 operation. We back this with:
Comprehensive Training: Detailed on-site instruction for your team on operation and maintenance.
Readily Available Spare Parts: A global network ensures critical parts like heating elements and sealing strips are accessible.
Expert Technical Support: Remote and on-call assistance to troubleshoot any complex operational issues, maximizing your investment return.

This combination is a revolutionary step in bag manufacturing technology, directly addressing the limitations of cold cutting. The Flying Knife System ensures continuous, high-speed production without the inertia of stop-and-start mechanisms. Crucially, the immediate Hot Slitting action melts and seals the cut edges of the side gusset and bag body in one seamless motion. This thermo-sealing process fuses the laminate layers—especially critical in woven PP and other laminated materials—preventing delamination and fraying. The result is a bag with superior edge strength, a pristine appearance that resists wear and tear, and significantly reduced customer returns due to edge failure.

Inconsistent side gusset formation often stems from imprecise folding and inadequate tension control. The CHOVYPLAS machine integrates a servo-driven gusset forming system with independent, digitally-adjustable tensioners. This allows for micro-adjustments specific to different material slip characteristics—whether handling slick laminated films or rigid woven fabrics. Combined with precision-guided folding plates and optional pre-heating units, the system guarantees sharp, stable, and perfectly flat gussets every time, eliminating the wrinkles and bubbling that degrade bag quality and stall productio

For heavy-duty bag applications, seal integrity is non-negotiable. CHOVYPLAS machines are equipped with high-pressure, double-heated sealing jaws that apply sustained heat and pressure across the entire bottom sealing and side gusset areas. Our proprietary control system maintains temperature stability within ±1°C, ensuring complete material fusion without weak spots. This setup consistently produces seal strengths that exceed industry standards for heavy-duty packaging, reliably supporting loads of 25kg to 50kg and beyond, as validated by our in-house peel and tensile strength testing.

We've engineered our machines for agility in today's high-mix production environments. Key adjustments for bag length and side gusset width are facilitated through the user-friendly HMI interface and hand-wheel mechanisms with precision scales. Most routine changeovers can be completed by a trained operator in under 10 minutes without specialized tools. This drastically reduces downtime and empowers our clients to accept smaller, more profitable custom orders without sacrificing efficiency on longer runs.
