■ Storage Examples








■ Attention
-
No Heating or Open Flames: Do not use for boiling in a pot, water baths, ovens, or over open flames.
-
Microwave for Defrosting Only: Do not use for heating or cooking; use only for defrosting.
-
Fill Up to 80% Capacity: Overfilling or putting sharp objects inside may cause the bag to tear. Keep contents under 80% full for storage.
-
Beware of Leaks: Do not use as a container to carry liquids. When storing liquids horizontally or defrosting them, place a tray underneath to prevent potential leaks.
-
Do Not Apply Pressure: Avoid pressing down or placing heavy objects on the bag after sealing, as it may cause the bag to open or burst.
-
Polyethylene Odor: A slight odor from the polyethylene manufacturing process may remain.
■ Precautions for Microwave Defrosting
-
Open the Zipper Partially: Always open a portion of the zipper before you begin defrosting.
-
Use a Deep Dish for Liquid Foods: Always place a deep dish under the bag when defrosting liquid foods, as contents may leak if pressure is applied to the zipper area.
-
Caution with High-Oil or High-Salt Foods: Foods high in oil or salt (such as curry or stew) may partially exceed the heat-resistance temperature and cause the bag to burst, even when using the "Defrost" or "Low" setting depending on the microwave model.
■ Storage Precautions
Keep Away from Heat Sources: Do not place near gas stoves, toaster ovens, or other heat sources. High temperatures may melt the bag.
