How to calculate the required amount
To calculate the required amount of oxygen absorber in a packet or container, you need to know the volume of the packet or container, the type of product being packaged, and the desired oxygen level inside the packaging. Follow the steps below: 1. Determine the volume of the packet or container in cubic centimeters. You can measure the length, width, and height of the containers and multiply them together. 2. If the packaging does not have specific dimensions, weigh the empty package first, then place it in a water-filled container and weigh the displaced water. Use the following formula to calculate the amount of oxygen: Oxygen (cc) = Volume of packaging (cc) x (Desired oxygen level - Ambient oxygen level) / (100 - Ambient oxygen level) Note that the ambient oxygen level is approximately 21%
Based on the calculated amount and with the help of the guide table, select the appropriate size and number of oxygen absorbers. The recommended number of sachets for different products is as follows. Note that all products, especially fruits, vegetables, and nuts, must be free of damage, bruises, and any mold or fungus before packaging. The appropriate number of sachets should be placed in the packaging without opening them.
