Impulse sealer 300 without cutter

The 300 impulse sealer without cutter can be used for heat sealing pre-made pouches. For smaller packaging quantities, it can be the right choice when the task is to close the pouch mouth and the product does not require vacuum packing. The version without a cutter retains the film section above the seal. This allows a workflow in which the pouch length is sized to the contents in advance and the top section does not need to be trimmed after sealing.

For pre-sized pouches

The pack size is determined by the overall dimensions of the product and the portion. After filling, enough material should remain at the top of the pouch for the mouth opening to be placed smoothly on the sealing surface. An even allowance helps produce packs with a uniform appearance. The required width must be checked on the flattened pouch mouth, especially with gusseted or wider designs. We match the machine's working size to this so that the seal can be formed across the entire opening.

Adjustable time for the right bond

The machine's sealing time is adjustable by potentiometer, so the setting can be matched to the selected film. During the trial, it is advisable to examine the continuity and strength of the cooled seam as well. Increasing the time alone does not make creased film or film contaminated with product a suitable sealing surface. The material, a clean surface and the correct setting are all needed for a good result. If the structure or thickness of the pouch changes, the previously used setting must be checked again.

Strip of film retained above the seal

With this machine, the top edge of the pouch remains on the pack at its original length. The role of this strip is best defined when ordering the pouches: it can provide a convenient top section to hold or an allowance matched to the pack appearance. The label position and the opening method must be designed so that the seal is not damaged. It is advisable to look at the finished pouch in its actual retail setting as well. Uniform sizing reduces the need for subsequent adjustment.

Regular checks in daily work

The area around the Teflon-coated sealing wire must be kept clean, and the condition of wearing surfaces must be checked according to use. When designing the work surface, support for the filled pouch must also be considered, so that the weight of the product does not pull the film out of place during sealing. The width of the flat seal is a characteristic of the specific version, which we agree together with the required pack. Checking the seal should be a consistent operation, especially when starting work and after a change of material.

For the 300 impulse sealer without cutter, it is worth choosing a pouch whose size and sealable layer suit the task. Please send us the packaging material details, the product to be filled and the daily quantity. Our colleagues will help you put together the machine and material selection criteria needed for sealing, so that manual packaging can run in a predictable routine.
