How our sizes work

A bit about heat sealers



These bags are made from a material with a much lower sealing temperature than plastic bags, so we recommend a heater sealer that you can adjust the temperature ( which means they also have the benefit of using less energy).

We don't sell heat sealers as they are so cheap to buy , it's not worth us selling them but we use an Impulse heat sealer which we bought from eBay as you can adjust the temperature and they are really well priced ( ours cost us about £20).

* please note this is not a recommendation but a suggestion (sorry we do need to get the legal bit out of the way).
