What Does “Seal Width” Mean for a Sealer?

When shopping around for a heat impulse sealer, the two most important questions you will need to answer are:

Q:  What sealer size should I purchase?
A:  How wide is your bag?  This one is easy.  If your bag is 6″, then you will need a sealer that will fit your 6″ bag.  The closest size to that is our 8″ hand sealer.

Next Q:  What seal width should I choose?
There are a variety of seal widths that a sealer can make.  There are two types of heating elements: round or flat. The round wire is mainly used to cut and seal with no excess material above the seal.  Depending on the width of the flat wire element, sealers are available in 2-3mm, 5mm, 8mm, or 10 mm.   If you are sealing thicker materials, you may want to choose a wider seal width for better heat penetration.  Please download our seal width guide for a better idea of the type of seal width you should choose.  The most basic seal width is 2mm and if you are sealing a general poly bag, the 2mm seal width will do the trick.
