When choosing a heat sealer, it is quite important to know the material that is going to be sealed. Also, you should have the material width and thickness available. In this way, you can make the selection process quite easier. This ensures that the heat sealing machine you purchase can seal your material. In this post, we reveal four important features of these types of machines to help you choose the right one for you.
What is a heat sealer?
Heat sealer can be defined as a machine that is used in sealing plastic material using heat. There are several types of heat sealers and finding the right one can be quite overwhelming. There are two major types of these machines: Direct heat sealer and impulse heat:
Impulse heat sealers
The
se types of heat sealers do not need warm up time, and they seal through the application of energy to sealing area. This is then followed by cooling. They use power when its jaw is lowered. If you want to seal a thermoplastic material, then it is advisable to use one that needs a low seal temperature. You will find them easy to use as there is no need for warm-up time. Moreover, they are economical (electricity is only used during the sealing process) and very safe ( not all components are always hot).
Direct heat sealers
These are designed to maintain constant heat in the both jaws. They use power whenever they are turned on. It is recommended to use this type of heat sealer for various materials such as gusset bags, poly cello films, aluminum foil, waxed paper, coated PP, and most thicker materials.
Vacuum sealers
These are designed to remove air from a product before you seal into the impermeable package. Vacuum sealing is recommended to prevent spoilage, corrosion, and oxidation. The barrier bags use PE, and PP bags are all porous. Thus, they are not ideal for long-term storage.
The following are some of the things to consider when choosing a heat sealing machine:
Size
The size of a sealing machine is dependent on the width of the material, which is being sealed. It is recommended to add an inch to the width of material for easy handling. The cutters on sealer trim at slightly less than the width of sealer arm.
Speed
Portable sealers are known for being versatile, handy, and lightweight. On the other hand, hand sealers are economical and simple. They can easily seal over 20 packages per minute.…
