FIBC Sewing Machine 80700 Series | Longsew

Introduction to the 80700 Series FIBC Bag Sewing Machine

The FIBC Bag Sewing Machine 80700 series is a cornerstone of the heavy-duty FIBC (Flexible Intermediate Bulk Container) bag production industry. Designed for durability and precision, this machine is tailored to meet the demands of industrial-scale manufacturing. Whether you're producing jumbo bags for agriculture, construction, or logistics, the 80700 series offers versatile configurations to suit your needs. With a long-standing reputation for reliability, this model remains a top choice for manufacturers worldwide.

Key Features and Advantages

The 80700 series is engineered to deliver exceptional performance in challenging environments. Its robust design and advanced functionalities make it ideal for high-volume production. Below are the standout features:

1. Double Needle Chain Stitch Technology

The Double Chain Stitch Sewing Machine employs a 4-thread parallel chain stitch (401+401) system, ensuring strong and seamless seams. This configuration is particularly effective for FIBC bags, which require reinforced stitching to withstand heavy loads. The machine's top and bottom feeding systems ensure even fabric distribution, minimizing wrinkles and defects.

2. Versatile Configurations

The 80700 series offers multiple variants to cater to specific production requirements:

• 80700C: Single-needle model with basic functionality, available with clutch or servo motors.
• 80700CD: Double-needle model with similar motor options, ideal for faster production.
• 80700CD4H: Advanced version with pneumatic foot lift, hot cutter system, needle position fixation, and cooling. Requires a servo motor for optimal performance.

3. Enhanced Durability and Power

With a maximum sewing thickness of 18mm, the 80700 series is built to handle thick materials like woven polypropylene. The 750W servo motor provides consistent power, reducing energy consumption while maintaining high-speed operation (up to 1,400 rpm). The machine's stainless steel (S.S. 304) table top and body shell ensure resistance to corrosion, making it suitable for food-grade and other high-standard applications.

4. Optional Features for Customization

Manufacturers can enhance the machine's functionality with optional upgrades:

• Pneumatic Foot Lift System: Automates the foot lift mechanism for smoother operation.
• Hot Cutter System: Ensures clean, sealed edges for FIBC bags, preventing fraying.
• Needle Cooling System: Prevents overheating during prolonged use, extending the machine's lifespan.
• Spout Table Top and Stand: Facilitates the production of bags with spouts or special shapes.

Technical Specifications

Application Scenarios

The 80700 series is widely used in industries requiring durable, large-volume packaging solutions. Key applications include:

• Agriculture: Packaging fertilizers, seeds, and grains in FIBC bags.
• Construction: Transporting cement, sand, and other bulk materials.
• Logistics: Securing goods during long-distance shipping with reinforced bags.
• Food Industry: Producing food-grade FIBC bags with hygienic, stainless steel components.

Its adaptability to different materials and configurations makes it a versatile choice for manufacturers across sectors.
