Structural characteristics and advantages and disadvantages of a container bag sewing machine

With the booming development of global logistics and transportation, the demand for packaging products such as container bags and packing bags is gradually increasing. To meet this demand, container bag sewing machines have emerged in industrial sewing.

Because the materials sewn by container bag sewing machines vary in thickness, important parameters besides sewing speed include sewing thickness, presser foot lift height, and turning ability. Container bag sewing machines are generally large machines, and due to the limitations of their sewing thickness on the machine, they require excellent fatigue resistance and sewing stability. In addition, most container bag sewing machines use differential feeding or synchronous feeding, which significantly improves the sewing life of the machine.

Container bag sewing machines have oscillating hook and rotary hook structures, each with its own advantages and disadvantages. Advantages and disadvantages of oscillating hook sewing machines: Machines with an oscillating hook structure use a metal shell, which is highly durable, but they are noisy, prone to thread jams, require frequent thread changes, and have relatively lower operating speeds (older oscillating hook models had these problems, but through continuous improvements and innovations, oscillating hook machines have successfully addressed noise and operating speed issues).

Advantages and disadvantages of rotary hook sewing machines: They use resin materials, which are less wear-resistant, but they are quieter and, due to the material and construction, experience fewer thread jams and have faster operating speeds.

Different structures of container bag sewing machines are suitable for different thicknesses of materials. Before sewing, the appropriate model should be selected according to the material.
