Pair with Oxygen Absorbers
- Add absorbers before sealing to prevent spoilage.
- Absorbers remove the oxygen portion of air (approx. 20%).
- Bags may deflate slightly — this is normal.
- A vacuum sealer is required for a true vacuum finish.
- Use our online calculator to choose the correct absorber size.
How to Seal Mylar Bag 15*20cm
- Fill the bag, leaving 10–12 cm at the top.
- Add oxygen absorbers.
- Press out excess air.
- Seal using one of the following methods:
- Vacuum Sealer: Use the sealing function; vacuuming is optional when using absorbers.
- Impulse Sealer: Fast, efficient sealing option.
- Hair Straightener / Iron: Use highest heat, seal for 2–4 seconds, then repeat if needed.
Note: Heat sealing traps air. Oxygen absorbers remove only the oxygen portion. A vacuum sealer is required for complete air removal.
What Can Be Stored
Best suited for long-term storage of dry, low-fat foods:
- Flour, rice, grains and pasta
- Dehydrated fruits and vegetables

Great mylar bags. I seal them with a basic strip heat sealer… works as I wanted. Perfect for a variety of dry beans, dry soup mix, lentels and grains. I will be using to put split peas and corn maize in the next couple of days.
Thanks Keith,
We’re happy to be of service.
