EasySeal bag sealer: keep food fresh without clips

A bag clip does not make a bag airtight. It folds the top over and holds the fold, which slows air exchange down a little and does nothing about humidity. That is why crisps go soft, coffee goes flat and frozen food picks up ice crystals regardless of how carefully you clipped it.

A heat sealer melts the two faces of the plastic together into a continuous seam. It is the same thing the factory did before you opened the bag, and it takes about two seconds.

How to get a good seal

• Pull the bag flat and taut before sealing — a wrinkle in the plastic is a channel for air
• Leave a couple of centimetres of clear plastic above the contents so nothing is caught in the seam
• Let the timer run its full cycle rather than pulling away early
• Run your fingers along the seam afterwards; a good seal is stiff and slightly glossy

What it works on

Standard polyethylene bags — crisps, cereal liners, frozen vegetables, bread bags, freezer bags, coffee bags with a plastic inner. Paper bags and foil-only packaging will not fuse, since there is no plastic layer to melt.

Why the magnet is not a gimmick

Kitchen gadgets fail by ending up in a drawer. A magnetic back means it is stuck to the fridge at eye level, next to the bag you are about to close — and that is most of the reason this one gets used daily while the drawer version does not.
