Abstract: A device for controlling package pressure and gas flow for a packaged good comprises a film having a first opening for exposure to the inside of a package and a second opening for exposure to the outside of a package. A channel extends between the first opening and the second opening. The dimensions of the channel are configured to control the rate of flow of CO2 (cc/min @ 1 PSI) from the inside of the package to the outside of the package and control the oxygen transmission rate (cc/day/Atm) from the outside of the package to the inside of the package so that a flow of CO2/OTR ratio is at an acceptable level for the packaged good.

Abstract: A label with a microchannel for venting a package.

Abstract: A vent for a package includes a multilayer laminate film comprising a vent having a first breach, a second breach, and a laser-formed channel extending therebetween, and the length and cross-sectional area of the laser-formed channel are configured to exhaust CO2 at a rate greater than a counter-flow diffusion rate for oxygen or water vapor.

Abstract: An optimized package for holding a perishable produce that balances between optimum aerobic and anaerobic conditions. The package has a body, formed of a package film having a first size and shape, formed with laser micro perforations formed according to a relationship between a shelf life of said first contents in said package for different oxygen transfer rates expressed as volume of oxygen per time period per package per atmosphere. This is set to optimize between anaerobic conditions and aerobic conditions. There are a number and size of micro perforations, to obtain an optimum oxygen transfer rate. The micro perforations can be formed in a location of the package which retains airflow through the micro perforations when multiple of said packages are stacked. There can also be a humidity reduction device, which can be a valve, or a vapor transmitting film, or a hydroscopic salt on the exterior of the film.

Abstract: A humidity controlled package that uses a humidity sensitive valve that opens and closes an opening to control a humidity in the package. The package has a package holding area inside the package. The humidity level in the package controls the valve to open to allow air flow between an inside of the valve and an outside of the valve, and close to prevent air flow between the inside and outside of the valve. At least part of the valve is in the package. In one embodiment, the package is vented when the humidity value gets higher than a setpoint. In another embodiment, a sachet of dessicant is opened by the humidity level.

Abstract: A laser formed vent in packaging material, formed by an interior breach and an exterior breach, which are connected to one another by a channel. The next interior breach an exterior breach are laterally offset from one another, the channel is formed by vaporizing a bubble in an interior layer, for example a foil layer. In one embodiment, the bubble can be crushed, but returns to its original configuration.

Abstract: A composite printing plate having a body including a first surface and a generally opposed printing surface, the body made of a polymeric matrix and a plurality of beads dispersed in the polymeric matrix. The plate further including a design in the printing surface defined by a base and an upper margin generally coplanar with the printing surface, wherein some of the beads extend from the base towards the upper margin, such that the at least some of the beads are at least partially exposed in the design.

Abstract: A composite printing die having a body and a texture selectively defined thereon to form a printing surface, the body including a polymeric matrix and a filler dispersed in the polymeric matrix, wherein the filler includes particles made of an elemental metal, any alloys thereof, and any combinations thereof.
