High Speed Calendar Bag Making Machine

The CP-1000BS5+AP adopts a 5-line synchronous production design with a servo drive system (Yaskawa Japan servo motor) and automatic punching device. Its core principle lies in the integration of hydraulic film feeding, automatic tension control, and 5-line hydraulic punching technologies. The heavy-duty unwinder with AC motor drive ensures stable unwinding of films with a maximum diameter of 1000mm, while the independent temperature control hot cutting unit enables precise processing of 0.01-0.04mm thin films. This technical configuration allows the machine to simultaneously produce bottom-sealed bags and calendar bags, suitable for both blank and printed film materials

The machine realizes 5-line synchronous production through a dual servo motor traction system and Panasonic PLC control. Key technical measures include: 1) Each line is equipped with an independent tension control system, with unwinding tension accuracy controlled within ±1N; 2) The Italian Datalogic photocell performs real-time tracking with a positioning accuracy of ±0.5mm; 3) The hot sealing knife uses copper alloy material with PID temperature regulation (control accuracy ±1℃). In actual production, the 5-line bag width can reach 200mm×5 lines, and the linear speed is 85m/min, ensuring consistent bag length error within ±1mm (tested according to ISO 15217 standard).

This machine is mainly used for producing bottom-sealed bags and calendar bags, with functions including bag blocking, perforation, and punching. Optional devices include a 1-5 line gusset system, which can be customized according to customer needs for different punching patterns (such as kidney-shaped holes, hanging holes) and perforation lines. The product range covers 5-line blank/printed calendar bags, suitable for packaging in food, daily chemicals, and other industries. When equipped with an automatic stacking device, it can realize fully automated production from film unwinding to finished product collection

The machine's nominal production speed is 180pcs×5 lines/min, but actual performance depends on film materials and bag specifications. According to third-party testing (ASTM D3985 standard), when processing 0.02mm LDPE film and producing 300mm length bags, the stable operation speed can reach 165pcs×5 lines/min, with a continuous operation time of over 8 hours and a failure rate ≤0.5%. The key stability indicators include: 1) Tension control fluctuation ≤±2%; 2) Temperature control deviation ≤±1℃; 3) Bag length accuracy ±0.8mm. The whole machine adopts a heavy-duty frame structure (weight 2800kg), which effectively reduces vibration during high-speed operation.

The machine is suitable for processing various plastic films with thickness 0.01-0.04mm, including LDPE, HDPE, LLDPE, and printed composite films. The maximum unwinding width is 900mm, and the effective bag length range is 250-700mm. According to DIN EN 13900-2 standard testing, it can stably process films with surface tension ≥38dyn/cm, and the minimum friction coefficient between film layers is 0.25 (test method: ASTM D1894). For special materials (such as biodegradable PLA/ PBAT blends), the optional hot air auxiliary sealing device can be configured to ensure sealing strength ≥1.8N/15mm (tested according to GB/T 1040.3).

Sealing strength verification: Use a tensile testing machine (model: INSTRON 5965) with a testing speed of 300mm/min, take 10 samples for each batch, and the average value should ≥2.0N/15mm (conforming to ASTM F88 standard). Punching accuracy verification: Use a coordinate measuring machine (accuracy ±0.01mm) to test the position deviation of 100 consecutive punching holes, with a maximum deviation ≤±0.3mm. The company can provide a third-party testing report issued by SGS, including test data such as temperature distribution uniformity (hot sealing knife surface temperature difference ≤±2℃) and punching die service life (≥1 million times).

The total power of the machine is 17.6kW, and the actual energy consumption per 1000 bags is about 1.2kWh (based on 300mm bag length). Energy efficiency calculation formula: Energy efficiency index (kWh/1000 bags) = Total power (kW) × Operating time (h) × 1000 / Output (bags). Compared with similar models, it saves about 15% energy through: 1) Servo motor energy feedback system; 2) Automatic shutdown function for idle sections; 3) PID intelligent temperature control. Taking a daily production of 500,000 bags as an example, the annual energy cost can be saved by approximately $8,200 (calculated at $0.12/kWh).

The ROI calculation should consider three factors: 1) Labor cost savings: 5-line production reduces 2 operators compared to single-line machines, saving about $36,000 annually (based on $15/hour); 2) Material utilization improvement: Automatic tension control reduces film waste by 3%, saving $12,000 annually for 200 tons of film consumption; 3) Maintenance cost: The average annual maintenance cost is about $3,500 (including wearing parts like hot sealing strips and cutting blades). Assuming the equipment investment is $180,000, the simple ROI is approximately 2.3 years. For customers with high production volume (over 1.5 million bags/day), the payback period can be shortened to within 1.8 years.

The machine provides a 12-month warranty covering electrical components (PLC, servo motor), hydraulic system, and mechanical transmission parts. The warranty does not include wearing parts (hot sealing knife, cutting blade) and damage caused by improper operation. Technical support response time: 2-hour online response (working days), 24-hour on-site service for key customers (Asia-Pacific region), and 48-hour on-site service for overseas customers. The company maintains a spare parts warehouse in Shanghai with common parts available for immediate delivery, and special parts have a lead time of ≤7 days.

The machine complies with CE certification (EN 60204-1 electrical safety standard) and ISO 9001 quality management system requirements. The certification documents include: 1) EC Declaration of Conformity; 2) Risk assessment report (according to EN ISO 12100); 3) Electrical schematic diagram and parts list. Customers can request the company to provide certification documents issued by TÜV SÜD, including test reports on noise (≤85dB(A) at 1m distance) and electromagnetic compatibility (EN 61000-6-2). For North American markets, optional UL 508A industrial control system certification can be provided, with an additional certification cycle of 4-6 weeks.
