Abstract
Microperforated packaging materials for use in modifying or controlling the flow of oxygen and carbon dioxide into and/out of a fresh produce container, where the microperforations are specifically tailored in size, location and number for the specific produce. A packaging system of designating specifically tailored microperforated containers for particular fresh produce to optimally preserve the produce. A method of making the registered microperforations on the packaging material using a CO2 laser and a sensor mechanism.
Claims8
A microperforation system for making microperforations in a registered target area of packaging material, comprising:
- a polymeric web;
- a laser mounted over said web;
- a sensor to identify said target area on said packaging material;
- a laser controller to drill said microperforations in said target area;
- and
- a processor coupled to said laser controller and said sensor, said processor performing calculations, wherein said calculations control a fresh produce package atmosphere within specified O2 and CO2 concentrations and wherein said calculations determine an optimal number and size of said microperforations of said target area.
