Below is the detailed product data based on Amazon-listed information and manufacturer details:

Rechargeable and Cordless Convenience

One of the standout features of the Moonshan cordless bag sewing machine is its 5,200mAh removable lithium battery. This high-capacity power source allows operators to work without the restrictions of power cords.

Benefits of the 5,200mAh Battery

• High-capacity energy storage for extended runtime
• Removable design for convenient charging
• Visual power display for battery level monitoring
• Freedom to operate in outdoor or remote locations

The cordless functionality makes it particularly suitable for:

• Agricultural farms
• Grain storage warehouses
• Feed processing facilities
• Construction packaging sites
• Outdoor bulk packaging areas

Unlike traditional corded machines, this battery bag closer eliminates tripping hazards and reduces dependency on fixed power sources.

Adjustable Speed Control for Versatile Operation

The Moonshan GS8-073D bag closing machine features a speed control switch that allows users to adjust operating speed according to material type and stitching requirements.

With a maximum output of 2,600 stitches per minute and the ability to seal a bag in approximately 2 seconds, it is designed for high-volume packaging.

However, certain materials may require slower stitching speeds to ensure precision. The adjustable speed feature provides flexibility for:

• Thin non-woven fabrics
• Medium-thickness woven sacks
• Heavy kraft composite bags
• Leather packaging materials

This flexibility enhances usability in mixed packaging environments where material types vary throughout the workday.

High-Speed Performance and Productivity

Speed directly affects productivity in industrial packaging. The Moonshan industrial bag closing machine operates at:

• 2 seconds per bag
• Up to 2,600 stitches per minute
• 90W motor power
• 11,000 RPM motor speed

Under optimal conditions, this output enables sealing of more than 5,000 bags daily.

High-speed stitching does not compromise seam consistency. The stitches are even and uniform, helping prevent product leakage or seam breakage during transport and storage.

For operations handling large volumes of feed sacks, rice bags, or flour packaging, this level of efficiency can significantly reduce labor time.

All Copper Core Motor Performance

Unlike standard motors that may degrade over time, the Moonshan bag sewing machine incorporates an all-copper core motor.

Advantages of the Copper Motor

• Improved electrical conductivity
• Higher efficiency
• Stable power delivery
• Reduced internal resistance
• Increased durability

With 90W power output and 11,000 RPM motor speed, it provides strong torque for sealing bags up to 5 mm thick.

Although the manufacturer has attempted to reduce operational noise, high-speed industrial motors naturally produce sound. This is expected in machines designed for heavy-duty packaging use.

7–10mm Adjustable Stitch Length

A secure seal is critical in packaging bulk goods. The adjustable stitch length between 7mm and 10mm allows operators to optimize seam strength.

Shorter stitch lengths create tighter seams for finer materials. Longer stitch lengths can be used for thicker materials without over-compressing the seam.

Benefits include:

• Improved seal integrity
• Reduced risk of contents spilling
• Stronger closure for transportation
• Customizable stitching based on material thickness

This feature ensures the Moonshan adjustable stitch bag closer adapts to various packaging needs.

Manual and Automatic Thread Cutting System

The dual cutting system enhances efficiency and flexibility.

Automatic Thread Cutting

After sewing, guide the thread into the cutting slot for quick trimming.

Manual Thread Cutting

A blade located beside the machine allows manual cutting when preferred.

Automatic cutting speeds up repetitive operations, while manual cutting offers control for specialized tasks.

This feature reduces downtime between bags, particularly in high-volume workflows.

Recommended Material Thickness

The Moonshan cordless bag closer is recommended for materials between 0.3mm and 5mm thick, depending on composition.

Suitable materials include:

• Woven polypropylene bags
• Non-woven feed sacks
• Rice packaging bags
• Flour and grain sacks
• Kraft composite bags
• Leather materials
• Towels and industrial textiles

Operating within this thickness range ensures consistent stitching and seam durability.

Maintenance and Oiling System

Long-term performance depends on proper maintenance. The built-in oiling hole allows easy lubrication without disassembling the machine.

Maintenance Benefits

• Quick oil application
• Reduced internal friction
• Extended component life
• Improved motor efficiency
• Stable stitching performance

Regular oiling ensures smooth operation, especially in high-speed industrial environments.

Build Quality and Construction

The Moonshan GS8-073D bag sewing machine combines engineering plastic and stainless steel materials for durability and weight balance.

At 7.2 pounds, it is slightly heavier than some models, but this added weight contributes to stability during high-speed stitching.

Design highlights include:

• Durable stainless steel components
• Impact-resistant engineering plastic casing
• Ergonomic handle grip
• Balanced center of gravity

These design choices enhance control and reduce vibration during operation.

4. Aligning bag edges
5. Running the seam
6. Cutting thread automatically or manually

Operators familiar with industrial bag closers will adapt quickly to its controls.

Cordless vs Corded Industrial Bag Closers

The cordless design provides greater flexibility, particularly in large storage facilities or outdoor environments.
