Frequently Asked Questions
Are these lunch bags truly leakproof for dressings and wet foods?
Most of these models use hot-pressed aluminum or PEVA inner liners designed to be leak-resistant; they protect the bag from spills but it's still best to use sealed condiment cups or screw-top dressing containers inside and to wipe the liner after any spill.
Can I fit standard bento boxes in these bags?
Yes. The double-deck/double-compartment designs (Artelaris, ATRIPACK and the Gafetrey models) are sized to accommodate common bento boxes and Tupperware. Check the bag dimensions against your container sizes; compact models (15L) suit smaller bento boxes while 24L models handle multiple or larger boxes.
How do I clean an insulated lunch bag?
Spot clean the exterior with mild soap and water. Wipe the inner liner with a damp cloth and mild detergent, rinse and air-dry fully before folding. Avoid machine washing unless the manufacturer explicitly states it’s safe, and check for any removable inner liners for easier cleaning.
