FAQ

What bag size should I choose?

The grams are not important for choosing the right bag size, but the volume of the raw material in milliliters.
WHAT WILL YOU NEED?
- a kitchen scale
- a measuring cup in ml
- the product you will be bagging
HOW TO PROCEED?
- put the measuring cup on the scale and reset the scale (TARE button)
- pour the desired weight of your product into the measuring cup ( e.g. 100g of nuts )
- now look at the measuring cup to see what measure the raw material reaches (e.g. 400ml )
- this is your final volume in ml. For our example we will be looking for bags with the nearest in line upwards, i.e. 500ml.

Can you send me a sample of the packaging?

Yes, we will be happy to send you a bag samples. How do I order a sample? On the product page, please choose the correct volume of the bag (Select a variant).

Why does the O2Zero® oxygen absorber heat up when the protective packaging is opened?

It's normal and okay. Don't worry.

Oxygen absorbers are small packets that contain iron powder and other ingredients that react with oxygen and remove it from a closed environment, such as food packaging. When the iron powder in the absorber reacts with oxygen, a process called oxidation occurs, which releases heat energy.

This heat energy is then transferred to the oxygen absorber's packaging, causing it to heat up. The amount of heat generated depends on the amount of oxygen absorbed and the size of the absorber.

It is important to note that the heat generated by an oxygen absorber is usually not sufficient to cause damage or destruction to the bag or its contents. In fact, heat can help create a more stable and fresher environment for food by reducing the amount of oxygen present, which can slow the growth of bacteria and mold.

Is the O2Zero® oxygen absorber harmful to health if accidentally consumed?

Accidental consumption of oxygen absorber should not adversely affect the health of humans (adults and children) and pets. O2O Oxygen Absorber is not intended for consumption, but is harmless and non-toxic.

The absorbers are tested by SGS, from the materials of the film (outside) to the ingredients (inside). All are safe and do not harm health.

An oral toxicity test has also been carried out and the result shows that the product is harmless if consumed. In case of accidental consumption, rinse your mouth and drink plenty of water. In case of problems, we recommend that you see a doctor.

What size O2Zero® oxygen absorber do I need?

We are happy to help you choose the right size absorber. Email us at info@doypacky.cz. We only need 3 pieces of information from you:
- package size in ml
- weight of raw material in 1 pack in grams
- shelf life of the product in days.
