A vacuum thermal sealer is a kitchen appliance that removes air from specialized bags and uses a heated strip to create an airtight seal, preserving food freshness up to five times longer. Typically featuring one-button operation, these compact devices prevent freezer burn and reduce food waste for home storage.

Key Features
Extended Shelf Life: Removes oxygen to prevent spoilage and freezer burn, ideal for meat, vegetables, and leftovers.
Operation: Place the open end of the bag into the chamber, ensure it is clean/dry, and trigger the vacuum-and-seal process.
Functionality: Many models offer "seal only" or "vacuum and seal" options, often with LED indicators.
Tips: Do not overfill bags (maximum 3/4 full); ensure the textured side of the bag is facing down for proper air removal.
Maintenance: Allow 1–2 minutes between seals to prevent overheating.
