The Bag Making Process Has Several Major Functions

Mar 15, 2025

The bag making process of a bag making machine usually has several major functions, including material feeding, sealing, cutting and bag stacking.
In the feeding section, the roll-fed flexible packaging film is unwound by a feed roller. The feed roller is used to move the film within the machine to perform the required operation. Feeding is usually an intermittent operation, and other operations such as sealing and cutting are performed during the feeding stop. Dancer rollers are used to maintain constant tension on the film roll. Feeders and dancer rollers are necessary to maintain tension and critical feeding accuracy.

In the sealing section, the temperature-controlled sealing element is moved to contact the film for a specific period of time to properly seal the material. The sealing temperature and sealing time vary depending on the material type and must be kept constant at different machine speeds. The sealing element configuration and the machine format related to it depends on the type of seal specified by the bag design. In most machine operation forms, the sealing process is accompanied by the cutting process, and both operations are performed when the feeding is completed.
During the cutting and bag stacking operations, operations such as sealing are usually performed during the non-feeding cycle of the machine. Similar to the sealing process, the cutting and bagging operations also determine the optimal machine form. In addition to these basic functions, the implementation of additional operations such as zippers, perforated bags, tote bags, anti-tamper seals, spouts, crown treatments, etc. may depend on the design of the packaging bag. Accessories attached to the basic machine are responsible for performing such additional operations.
