For industries requiring robust and reliable sewing solutions for FIBC bags, the 80700 series sewing machine stands as a pinnacle of engineering excellence. Designed specifically for heavy-duty FIBC (Flexible Intermediate Bulk Container) bag production, this machine combines durability, precision, and adaptability to meet the demands of modern manufacturing. Below, we explore its features, technical specifications, applications, and the company behind its innovation.

Product Overview

The 80700 series sewing machine is a cornerstone of the FIBC bag manufacturing industry. It is engineered to handle the unique challenges of producing large, heavy-duty bags used in agriculture, construction, and industrial logistics. The machine offers multiple configurations to suit varying production needs, including single or double needles, flat or cylinder beds, and manual or pneumatic foot lifts. Its versatility ensures it can adapt to different bag designs and functions, making it a preferred choice for manufacturers worldwide.

One of the standout features of the 80700 series is its ability to handle materials with a maximum thickness of 18mm, thanks to its powerful motor and reinforced construction. This capability is critical for FIBC bags, which often require strong, durable seams to withstand heavy loads. The machine also includes a filler cord function, enhancing its utility in complex bag assembly processes.

Technical Specifications

The 80700 series is available in three primary models: 80700C (single needle), 80700CD (double needle), and 80700CD4H (advanced double needle with additional features). Below is a detailed comparison of their specifications:

Key Features and Advantages

The 80700 series is distinguished by its advanced features and robust design. Here are some of its key advantages:
