A bag sealer machine is a device used in the production of sealing products, sealing packages, and any other thermoplastics/thermoplastic materials with heat. This is typically with flat thermoplastics or with dual-layered materials with several layers. There are typically four steps in a thermal-seal application cycle, with each of the four processes producing different end results. The first step is when the material is being pre-heated. In this case, the plastic material is placed in an area with the heating device and is exposed to heat for a predetermined period of time, usually a few minutes, before it is sent on its way to be packaged.
The second step in the sealing process is sealing the bag with the pre-heated plastic. During this step, the plastic bag is pumped with hot air, which is pulled up into the bag sealer unit where it presses against the pre-heated plastic for a set amount of time, which allows the bag to cool slightly, and then is sealed. The last step of this cycle is for the sealed bag to cool, and it is now ready to be shipped. It is important to note that this cooling process does not remove any of the bonding agent from the bag, so as long as the bag sealer remains closed during the sealing and shipping process, the sealant will remain intact for the delivery.
The final step in the entire process is where the bag sealer and bag go through the second printing process. During this step, the colors in the plastic are infused and imprinted on the bag sealer, creating a color match that is transparent and invisible to the eye. This process is also good when creating customized bags because it allows a creative designer to create the bag sealer and accompanying tags based upon an image selected by the client. This process of printing allows the sealers to be created with different colors, shapes, styles, sizes, logos, fonts, logos, or messages, thereby allowing a wide range of merchandise to be printed using this one simple step.
