Working long hours on construction sites means my lunchbox gets tossed around in the truck all day. Resealing my chip and sandwich bags stops crumbs from exploding all over my gear.
Mini Heat Bag Sealer
Description
Keep opened packets properly closed with the Kivvy Mini Heat Bag Sealer — a rechargeable handheld sealer that uses heat to create a clean seal across compatible plastic and plastic-lined bags.
Instead of folding, clipping or transferring food into another container, simply place the open edge of the original bag into the sealer and press. The heated strip fuses the two sides together, helping keep the packet securely closed between uses.
A built-in cutter lets you trim away excess packaging, while six adjustable heat settings make it easy to work with everything from thin snack packets to thicker freezer and storage bags.
- Seals and trims opened bags
- 6 adjustable heat settings
- 95 mm wide sealing strip
- Rechargeable USB-C design
- Magnetic base for convenient storage
Key Features
6 Heat Settings
Adjust the heat level to suit different bag thicknesses, from thin snack and crisp packets to thicker freezer and storage bags.
95 mm Sealing Strip
The wide heating strip helps create a continuous seal across most everyday household packets in a single press.
Built-In Cutter
Trim away uneven or excess packaging directly from the sealer without reaching for a separate pair of scissors.
Up to 300 Seals Per Charge
A built-in 1600 mAh rechargeable battery provides long-lasting cordless use and charges conveniently through USB-C.
Magnetic Base
Store the sealer directly on a compatible steel fridge door or other magnetic surface so it stays within easy reach.
How to Use
1. Switch it on
Press the power button. The sealer is ready to use without a preheating wait.
2. Select the heat level
Choose a setting from 1–6 depending on the thickness of the bag. Start with a lower setting for thin packaging and increase it for thicker bags.
3. Position the bag
Flatten the open edge of the bag and place it evenly beneath the sealing lid.
4. Press to seal
Close the lid and hold it firmly for a few seconds while the heated strip fuses the plastic together.
5. Trim if needed
Use the built-in cutter to remove excess packaging above the newly sealed edge.
For unfamiliar packaging, test the sealer on a small spare section of the bag first to find the most suitable heat setting.
Care & Safety
Compatible Bags
Designed for plastic and plastic-lined packaging such as snack packets, cereal liners, freezer bags, storage bags and many pet food bags.
Not a Vacuum Sealer
The Mini Heat Bag Sealer closes the open edge of a bag with heat. It does not remove air from inside the bag.
Cleaning
Allow the unit to cool completely before cleaning. Wipe the exterior and sealing area gently with a dry or slightly damp cloth.
Storage
Keep the sealer clean and dry when not in use. The automatic power-off feature helps prevent the unit from remaining active when left idle.
Do not immerse the sealer in water, use it on rigid materials, or allow children to operate it unsupervised.

A Fold Is Not A Seal.
Stop Air Getting Back In
Folding or clipping a packet still leaves gaps. A heat seal fuses the two sides together across the top for a properly closed edge.
Seal The Bag It Came In
Skip the extra storage tubs. Open the original packet, use what you need, seal it shut and put it straight back in the cupboard.
Stays Shut Until You Open It
Unlike a loose fold that can work itself open, the sealed edge stays closed until you deliberately cut below the seam.
Clean Seal. Clean Trim.
The heated strip closes the bag while the built-in cutter lets you remove excess packaging for a neat, finished edge.

Three Steps To A
Proper Seal
The Mini Heat Bag Sealer is made to be straightforward from the first use.
Lay the open top of the bag into place, press the lid closed, and hold for a moment. The heated strip seals the packet shut, while the built-in cutter helps leave a cleaner edge above the seam.
No clips, no folding, and no need to tip everything into another container. Just feed it, press it, and put it back.
Open It. Seal It. Store It.
The Mini Heat Bag Sealer keeps everyday food storage simple. Use the bag your food already came in, create a clean heat seal across the top, and put it straight back in the cupboard or freezer.
Choose the right heat
Select from six adjustable heat settings depending on the thickness of the packet. Start low for thin snack bags and move higher for thicker freezer or storage bags.
Press and seal the top
Lay the open edge flat inside the sealer, close the lid, and hold it for a few seconds while the heated strip fuses the two sides together.
Trim it and store it
Use the built-in cutter to remove any excess packaging, check that the seam is continuous, and put the original packet straight back where it belongs.
