ChefVentions 5 Pack Slim Ice Packs Red 7 x 4.8 x .47 in 200 g

Everyday Cooling for Lunch Bags

These slim ice packs serve students, office workers and outdoor enthusiasts who need reliable cold storage without the mess of melted ice. The red silicone bricks freeze solid in a household freezer and slide easily into lunchboxes, bento containers or breast-milk bags. Reusable gel keeps food and drinks chilled through a school day or a picnic. Buyers who need larger blocks for multi-day coolers will find these too small.

Fits Tight Spaces and TSA Rules

Each brick measures 7 x 4.8 x .47 in and weighs 200 g, so five packs stack flat in narrow totes, reusable shopping bags or checked luggage. The HDPE shell withstands repeated freeze-thaw cycles and passes security checkpoints when frozen solid. No loose ice means no water pooling at the bottom of a cooler. Builds that require rigid dividers or built-in refrigeration cannot use these flexible sheets.

Five-Pack Capacity and Temperature Hold

The set delivers five independent cooling zones that maintain 18 degrees F through phase-change gel denser than ice. Three hours at -10 degrees readies all packs for a full day of lunch-box duty or a beach outing. Extended trips without access to a freezer will exhaust the stored cold before the return leg.
