vacuum sealer

also called vacuum bag sealer

A countertop appliance that evacuates air from a plastic bag using a built-in pump and then heat-seals the bag mouth with a resistive element, extending food shelf life by removing oxygen. Beyond being a powered product it answers two questions: the width of its sealing bar (the primary spec — the maximum bag width it can accept) and optionally which sealing modes it offers (dry, moist, pulse). Distinct from a food processor or blender (no blade or speed selector) and from a cooking appliance (no cooking heat — the sealing element operates internally and automatically, not as a cooking temperature a user sets). Parented under PoweredProduct by the same logic as CanOpener and ElectricKnife: a fixed-function motorized appliance with no user-selectable speed or cooking temperature.
