FIBC Sewing Machine-HEBEI LONGSEW|Heavy-Duty Chain Stitch & Double Needle Efficiency

Introduction

The 80700 Series Double Needles Chain Stitch Sewing Machine is a specialized industrial solution designed for the production of FIBC (Flexible Intermediate Bulk Container) bags, also known as Jumbo Bags or Big Bags. Engineered for durability and precision, this machine is a cornerstone in the manufacturing of heavy-duty packaging solutions. Developed by HEBEI LONGSEW MACHINERY TECHNOLOGY CO. LTD, a company with a long history of innovation in textile machinery, the 80700 series combines advanced engineering with user-friendly features to meet the demands of modern industrial applications.

Product Overview

The 80700 series sewing machine is a versatile tool tailored for the FIBC bag production industry. It is available in three primary configurations: 80700C (single needle), 80700CD (double needle), and 80700CD4H (double needle with advanced features). Each model is designed to accommodate different production requirements, such as varying bag functions, bed types (flat or cylinder), and operational preferences (pneumatic foot lift or manual). The machine's robust construction and high-performance motor ensure reliability in demanding environments.

Key Features and Advantages
