method for laser mikroperforieren shell for packaging of fresh products in a modified / controlled atmosphere with measurement of the wall thickness of the shell

摘要

The present application relates to a method of and a system for laser microperforated fresh produce trays 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 such as by size, location and number for the specific produce. The packaging system tailors microperforated trays for particular produce to optimally preserve the produce, using a method of making registered microperforations on the trays using at least some of the following: a conveyor (20), a thickness measuring devise (30), a sensor mechanism (25,40), and a laser system (50,60) including optics.
