conditions in a food package during storage with pinhole defect sizes of 10 and 17 microns.
The results indicated that the OS film structures applied could only compensate for a defect size of 10 microns in the sealing layer but higher humidity accelerates the activation of the scavenger.
OS have to be incorporated in multilayer structures with the base layer providing the mechanical strength, the barrier layer reducing the O2 permeation rate of the film, the oxygen scavenging layer absorbing
