This equipment is specifically designed for the production of printed or non-printed vest-type bags (commonly known as T-shirt bags) using high-density polyethylene (HDPE) or low-density polyethylene (LDPE) roll film. The system integrates advanced automation technologies, featuring a programmable logic controller (PLC) as the core, combined with precise synchronized control from dual servo motors. An intuitive touchscreen interface enables parameter setting and real-time operational status monitoring. The machine completes the entire production process—including film feeding, sealing, cutting, and handle punching—in one continuous, automated cycle.
This integrated process significantly reduces manual intervention and transition time between steps, greatly saving labor while ensuring consistent product quality. By improving production efficiency, stabilizing output, and minimizing material waste, the equipment delivers substantial economic benefits and offers a reliable solution for high-volume, cost-effective bag manufacturing.

Cold knife cutting leaves a rough, frayed edge that can snag and looks unprofessional. CHOVYPLAS's Hot Slitting system uses a precisely heated blade to instantly melt and seal the cut edges of the bag handles and perforations. This process:
Eliminates Fraying: Creates a smooth, finished edge that enhances bag strength and appearance.
Enables Higher Speeds: The clean cut prevents material drag, allowing our Super High Speed T-shirt Bag Making Machine to achieve stable production at over 220 bags per minute without jamming.
Reduces Dust: By sealing the edge, it minimizes plastic dust generation, keeping the production area cleaner and reducing machine maintenance.
At speeds exceeding 200 bags/minute, inconsistent gussets are a major bottleneck. Our solution is a Servo-Driven Gusset Forming System. Unlike pneumatic or mechanical systems, it uses independent servo motors to precisely control the folding plates with positional accuracy of ±0.5mm. Coupled with adjustable tension control and pre-heating stations for the film, this guarantees that every side gusset is sharp, flat, and perfectly formed, preventing the wrinkles and bubbles that jam automatic packaging lines.
We design for relentless operation. The machine's frame is constructed from high-tensile steel to dampen vibrations at high speeds. Key components like the main drive system utilize Japanese-brand servo motors and German-grade bearings. This robust engineering, combined with a centralized automated lubrication system, allows us to guarantee a documented operational uptime of over 96% in three-shift production environments, as verified by performance data from multiple client sites.
Waste directly impacts profitability. The CP-series features an Intelligent Pre-Registration System. The photoelectric sensor and PLC work in tandem to achieve perfect print registration within the first 3-5 bags after start-up. Furthermore, our quick-release punch cartridge system allows for handle punch changes in under 2 minutes without tools, compared to 15-20 minutes on conventional machines. This combination reduces total material waste by up to 8% annually, a significant cost saving.
Certainly. Operational cost is a key differentiator. A traditional machine with clutch/brake systems runs constantly, consuming high power. Our All-Servo Drive Technology only draws peak power during movement cycles. Here's a simplified calculation:
Traditional Machine: 25kW * 70% load * 20h/day * 300 days = 105,000 kWh/year.
CHOVYPLAS All-Servo: Average draw of 9kW * 20h/day * 300 days = 54,000 kWh/year.
At $0.12/kWh, this translates to an annual saving of over $6,000 on energy alone, paying back the technology premium typically within 12-18 months.
Output efficiency is key. Using standard HDPE film, the CHOVYPLAS machine can produce approximately 55-65 kg of finished bags per hour. To calculate your exact cost-per-bag: (Film Cost per kg / Bags per kg) + (Energy & Labor Cost). Our high efficiency and low waste directly reduce the (Energy & Labor Cost) component. For a factory running 20 hours/day, the increased output and lower variable costs can improve gross margin by 5-10%, fundamentally changing your profitability.
We mitigate downtime risk through our Global Support Pledge. Critical spare parts like heating elements, ceramic slitting blades, and optical sensors are guaranteed to be shipped within 48 hours from our regional hubs. For technical support, we provide 24/7 multi-language remote assistance via video call, with the capability for secure, read-only PLC diagnostics to troubleshoot issues in real-time, often resolving problems before a technician would even arrive on site.
We invest in your people. Our "Operational Excellence" program includes:
On-Site Immersion Training: A week of hands-on training covering operation, daily maintenance, and common alarm resolution.
Digital Twin Simulation: Your operators can practice procedures and troubleshoot faults in a virtual environment before touching the physical machine.
Augmented Reality (AR) Guides: Using a tablet, your team can overlay 3D animations onto the machine for step-by-step guidance on complex tasks like punch assembly calibration.
Future-proofing is a core design principle. The modular sealing and slitting systems can be reconfigured for different material flow characteristics. We have already validated production with HDPE films containing up to 50% PCR content. The machine's advanced temperature control system (with ±1°C stability) is crucial for consistently sealing recycled materials, which often have variable melting points. By choosing CHOVYPLAS, you're not just buying a machine for today, but a flexible production platform for the next decade.
Our commitment is evidenced by our actions, not just our words. We offer a Performance-Based Warranty that includes a guaranteed Maximum Bag Cost calculation after installation. We provide annual Preventive Maintenance Health Checks and Software Upgrades at no extra cost for the first three years. Our goal is to be the last machine supplier you ever need to contact, and we structure our partnerships to ensure your long-term productivity and success are intrinsically linked to our own.
