FIBC Bags are usually made of thicker materials, such as polypropylene and polyester, which are more abrasive to sewing machines, big bag sewing machines need to have an excellent fatigue resistance factor and sewing stability to ensure continuous operation for a long time without malfunctioning or deterioration of sewing quality. Here we talk about the main types of sewing machines and their characteristics.
1. Lockstitch sewing machines
Lockstitch sewing machines are mainly used in two main categories: pendulum shuttle and rotary shuttle. Pendulum type lockstitch sewing machines realize lockstitch sewing through the swing of the pendulum; while rotary type lockstitch sewing machines complete lockstitch sewing through the rotation of the rotary shuttle. These two types of lockstitch sewing machines have their own characteristics, the swinging shuttle type is suitable for sewing thicker materials, while the rotary shuttle type is suitable for sewing thinner materials.
2. Chain Stitch Sewing Machines
The main models of chainstitch sewing machines include , GK81300,GK68-2 and so on. Chain stitch sewing machines are characterized by a chain-like stitch, high strength and durability, and are suitable for sewing thicker materials.
3. Overlock stitch sewing machines
Overlock stitch sewing machines are mainly used for sewing the edges of the container bags to increase the strength and aesthetics of the bags. The feature of overlock stitch sewing machine is that the stitch is in the shape of overlock, which can effectively prevent the edge of the material from abrasion and falling off.
In practical application, container bag sewing machines are widely used in many fields such as chemical industry, food, medicine, logistics and so on. For example, in the chemical industry, the container bag is used to package various chemical raw materials and products; in the food industry, the container bag is used to package rice, flour and other food products; in the pharmaceutical industry, the container bag is used to package medicines and medical devices; in the logistics industry, the container bag is used to transport and store a variety of goods. These application examples fully demonstrate the important role of sewing machines for container bags in industrial production and the prospect of wide application.
