My kids never roll up chip packets properly, so half-eaten snacks always went stale within a day. Sealing the bags closed with this gadget keeps everything crunchy until they want more.
Portable Magnetic Bag Sealer
Description
Keep opened packets properly closed with the Portable Magnetic Bag Sealer — a compact 2-in-1 heat sealer and cutter designed for everyday food storage.
Instead of folding, clipping or tying an opened bag, simply run the sealer across the top to create a clean heat-sealed closure while the built-in cutter trims away the excess edge.
With six adjustable heat settings, no preheating required and a 95 mm sealing strip, it works across a wide range of heat-sealable food bags from thin snack packets to thicker freezer and storage bags.

Care & Safety
Allow the heating strip to cool completely before storing or cleaning the sealer.
Wipe the outside with a slightly damp cloth and dry thoroughly. Do not place the device under running water or immerse it in water.
Keep the sealing strip free from crumbs, grease and melted film. Once completely cool, residue can be gently removed with a soft dry cloth.
Please note: This is a heat sealer, not a vacuum sealer. It seals the opening of a bag but does not remove air from inside.
Keep out of reach of children. The sealing strip remains hot briefly after use and a cutting blade is housed inside the lid.

Folded Isn’t The Same As

Folding or clipping an opened packet can hold the top down, but it can still leave gaps where air and moisture can get in.
The Portable Magnetic Bag Sealer uses heat to close the open edge of compatible plastic bags, creating a clean sealed closure instead of simply folding the packet over. Reseal your snacks, coffee, pet food, freezer bags, and more — then put the original packet straight back where it belongs.

No clips, ties, or complicated setup. Choose the right heat setting, run the sealer across the open edge, and close compatible food bags in seconds.
