Description

These 20CC oxygen absorbers are small packets used to reduce the amount of oxygen in packaging. They are commonly used for items such as food, medicine, and electronics that require a low oxygen environment to be preserved. They absorb oxygen through a chemical reaction between the iron powder inside and oxygen, thereby extending the shelf life of the item and preventing oxidation or microbial growth. These absorbers are self-activating. They only need to be exposed to air to start working. They are best stored in a dry, cool environment to maintain their effectiveness.

Absorption Capacity

These 20CC oxygen absorbers have a strong absorption capability, capable of absorbing approximately 20 milliliters (20CC) of oxygen. They are typically used in small sealed packages to reduce levels to below 0.01%, effectively preventing oxidation and microbial growth. This size is ideal for packaging dry food weighing around 100 grams or containers with a volume of approximately 500 milliliters.

Application

These 20CC oxygen absorbers are suitable for packaging with small container volumes, typically ranging between 500 ml to 1000 ml, depending on the amount of residual air and how tightly the contents are packed. They are commonly used for preserving small quantities of food or other items that require protection from exposure.

Applicable Products:

Small Food Packaging: such as snacks, dried fruits, tea, Chinese medicinal materials, etc.
Medicine and Health Products: such as capsules and tablets.
Industrial Use: Anti-oxidation of electronic components and metal parts.

FAQ

Q1: What should I pay attention to when using it in a high humidity environment?

In a high humidity environment (humidity over 75%), the effect of 20CC oxygen absorbers may be affected. Suggestions:

(1) Use a desiccant to reduce humidity.

(2) Choose an product designed for high humidity environments.

Q2: How to determine if it has expired?

Products that have expired usually have the following symptoms:

(1) The appearance color changes. For example, some products change from gray to dark brown.

(2) The packaging bag becomes hard, indicating that the chemical reaction has been completed.

Do not continue to use after it expires, and make sure to replace it with a new product.
