The main function of the gift bag making machine during operation
- Jul 31, 2018 -

During the operation of the gift bag making machine, its main functions include material feeding, sealing, cutting and code bags. In the feeding section, the roll-fed flexible packaging film is unwound through a feed roller. The feed roller is used to move the film within the machine to perform the desired operation. The feeding of the gift bag making machine is usually an intermittent operation, and other operations such as sealing, cutting, and the like are performed during the feeding stop.


The rollers are used to maintain a constant tension on the film roll. In order to maintain tension and critical feed accuracy, feeders and dancer rolls are required. At the sealing portion, the temperature controlled sealing element is moved to contact the film for a specific length of time to properly seal the material. The sealing temperature and sealing duration vary by material type and need to be constant at different machine speeds.


The gift bag making machine sealing element configuration and the machine form associated therewith depend on the type of seal specified by the bag design. In most machine operating modes, the sealing process is accompanied by a cutting process, both of which are performed at the completion of the feed.


Gift bag making machine during cutting and bag operations, operations such as sealing are typically performed during non-feed cycles of the machine. Similar to the sealing process, cutting and pocket operations also determine the best machine form. In addition to these basic functions, the execution of additional operations such as zippers, perforated bags, tote bags, tamper-evident seals, spouts, crown treatments, etc., may depend on the design of the package.
