WHAT ARE OXYGEN ABSORBER?
Oxygen Absorber is developed to protect packaged foods, pharmaceuticals and other products against mold growth, color change, rancidity, loss of nutritive values, insect damage and loss of quality. OUKPAK® absorbs oxygen in a sealed container and creates a deoxidized environment, where the concentration of oxygen is 0.1% or less.
Effective Field:
Mold/Insects/Oil/Color/Flavor/Nutrition
Formula to calculate the size of OUKPAK(V) oxygen absorber:
1. The first part is the residual oxygen volume in the packaging, also known as “headroom”.
Oxygen volume V1(by CC or ml)
=(packaging volume-goods volume)*oxygen content in the “headroom” or “headspace”
=(Length(cm or inch)*Width(cm)*Height(cm)-Weight of goods(g))*20%
2. The second part is the oxygen permeating into packaging during the shelf life.
Oxygen volume V2(by CC or ml)
=R*S*D
R: oxygen permeability rate(R) of packing film per day
S: surface area(cm²) or (square inch) of the packaging
D: shelf life (days)
3. The third part is oxygen absorber’s capacity lost during production and pre-using.
Oxygen volume V3(by CC or ml)
V3=(V1+V2)*50%
Total volume by cc needed for the application:
V=V1+V2+V3(CC)
