How to choose a food bag making machine?

Choosing a food bag-making machine requires considering multiple factors to ensure the equipment meets production needs, improves efficiency, and controls costs. Below is a detailed purchasing guide:

1. Define packaging requirements

Product characteristic analysis : It is necessary to consider the type of material (powder, granules, liquid, block or fragile), as different materials have different requirements for the equipment's filling system, metering accuracy, etc. At the same time, it is necessary to determine the size (length/width/thickness) and shape of the packaging bag (three-side seal, four-side seal, stand-up pouch, back seal pouch, etc.), as well as whether special functions (such as zippers, easy-tear openings) are required.

Capacity requirement assessment : Select equipment speed based on output (such as a small machine with 30-60 packs/minute or a high-speed machine with more than 100 packs/minute), and consider future expansion possibilities to select an upgradeable model.

2. Examine the configuration of core equipment.

Bag feeding system : Prioritize fully automatic models (robotic arm or suction cup bag feeding) to reduce manual intervention; pay attention to bag capacity, as a large-capacity bag bin can reduce the frequency of downtime for bag feeding.

Metering and filling systems : Volumetric metering is suitable for products with uniform particle size (such as candy); weighing metering (such as multi-head scales) is suitable for products with high accuracy requirements (such as milk powder, with an error of ±0.5g); liquid filling requires a peristaltic pump or piston pump, and attention should be paid to the anti-drip design.

Sealing method : Choose from heat sealing (common in plastic composite films), ultrasonic sealing (suitable for aluminum foil bags), or cold sealing (for heat-sensitive products such as chocolate) depending on the product characteristics. It is necessary to check the seal strength and tightness to prevent air leakage or bag breakage.

Control system : PLC + touch screen control, supporting parameter storage and fault alarms (such as missing bags, abnormal temperature). High-end models can be equipped with visual inspection (such as QR code recognition, weight re-inspection).

3. Materials and Compatibility Assessment

Packaging material compatibility : Confirm whether the equipment supports materials such as PE, PET/AL/PE composite film, and kraft paper, especially special materials (such as moisture-proof bags containing aluminum foil). If frequent film changes are required, choose a model with quick mold change.

Multi-specification compatibility : Different bag types can be switched by changing molds (such as bag makers and bag clamps), reducing downtime.

4. Evaluate key performance indicators

Accuracy : The weighing error should generally be between ±0.1% and 1%, which directly affects cost control (especially for high-priced raw materials).

Stability : Focus on the failure rate of equipment that has been running continuously for more than 8 hours, referring to the MTBF (Mean Time Between Failures) provided by the manufacturer.

Energy consumption : Comparing the power of different models (usually 3-10kW), long-term use will affect electricity costs.

5. Supplier Evaluation

Technical capabilities : We require a sample package (to test actual performance), and request to view videos of similar cases or on-site demonstrations. We also inquire about customization options (such as irregularly shaped bags or aseptic packaging).

After-sales service : Understand the warranty period (usually 1-2 years), response time (e.g., 24-hour on-site service), spare parts supply (common parts inventory), etc.

Cost analysis : Compare domestic brands (priced at approximately 50,000-200,000 RMB) with imported brands (such as Japanese and German brands, priced at over 300,000 RMB) to weigh the cost-effectiveness.

6. Safety and Compliance Requirements

Safety precautions : Check whether the equipment has safety devices that comply with CE or GB standards, such as emergency stop buttons, protective covers, and photoelectric protection.
