Patent ID: 7083837

Claim:
An improved packaging for establishing optimum atmospheric conditions for respiring produce, comprising: a non-porous polymeric material; a set of microperforations on said polymeric material, wherein said set of microperforations are drill holes and based on a number and a size of said microperforations, control and maintain said optimum atmospheric conditions within specified O 2 and CO 2 concentrations for said respiring produce, said optimum atmospheric conditions containing less than about 20.9% O 2 and greater than about 0.03% CO 2 , wherein said polymeric material provides a total O 2 Flux ranging from 150 cc/day-atm to 5,000,000 cc/day-atm and wherein each of said microperforations has an average diameter between 110 and 400 microns and said set of microperforations are placed in a registered target area on said polymeric material, said registered target area being a finite region on said polymeric material.
