sealing
also called seal type
How a food-storage vessel's lid attaches and seals to preserve its contents — an airtight snap-lock (a press-on clip-down lid that snaps shut, the 'Seal-O-Fresh' grade), a screw-top (a threaded lid that screws on, the classic jar), a clip-lock (side clamps that lock a gasketed lid, Lock&Lock style), a plain push-lid (a loose press-on cover that covers but does not airtight-seal), or a vacuum-seal (air drawn out for long preservation). This preservation/air-tightness mechanism is the real differentia of a Seal-O-Fresh airtight jar versus a plain push-lid box. Distinct from `lid_type` (A11): lid_type is the DRINKING-SPOUT dispensing interface of a bottle (sipper / straw / sports-spout / bite-valve — how liquid exits), whereas sealing is the food-preservation closure of a storage vessel (how well the lid seals contents in); they answer different questions on different families and never co-occur on one instance (a screw-cap drinking closure is not a screw-top airtight thread). Concern measurement, axis-eligible (an airtight vs plain container is a genuine buy choice).
Sealing is answered with one word chosen from the sealing types list — the same word shared across every product that uses it.
It belongs to measurement — its measurable, physical facts.
