- BPA-free and food-safe
- Pack of 50 Mylar Bags

Why Use Mylar Bags
- Strong and tear-resistant
- Flexible and collapsible as oxygen is removed
- Non-porous barrier for extended shelf life
- Cost-effective for home or commercial use
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 Bags
- 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
- Dried beans, cereals and powdered milk
- Herbs, spices and baking ingredients
High-moisture or high-fat foods should be rotated more frequently. Refer to our Mylar Storage Guide for recommended storage times.

What is a 15×20cm Mylar Bag used for?
A 15×20cm Mylar Bag is used for long-term storage of dry, low-fat foods and non-food items, protecting them from oxygen, moisture, and light damage.
How many oxygen absorbers will I need for a 15×20cm Mylar Bag?
The number of oxygen absorbers required for a 15×20cm Mylar Bag depends on the
void volume
of your package: • The volume of the sealed package • The volume occupied by the food product. The calculation isolates the packaging void (sealed package volume minus food weight) multiplied by 20% — as air is approximately 20% oxygen. Formula lovers can use the calculation directly, but for a shortcut,

Dry, low-fat foods such as flour, oats, rice, beans, pasta, herbs, spices, and dehydrated fruits or vegetables are ideal for storage in a 15×20cm Mylar Bag.

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.
