Polythene bags can be sealed with a bag sealer. These are cost effective machines that offer the ultimate seal.

Impulse heat sealers are used for any thermoplastic material such as a poly bag that requires a lower temperature.

Bag sealers can also be used to seal polycoated materials.

The size of heat sealer to use depends on the width of the material to be sealed. For easy handling, add one inch to the width of material to get the size of sealer needed.
