Micro-perforated films are flexible films with micro perforations used for packaging. They offer the opportunity to modify the oxygen transfer rate of packaging according to the packaged product. Gas permeability of micro-perforated films can be calculated by using a static or dynamic system. Most static experimental systems are used for calculating the permeability of micro-perforated films, since the flow of gas through the perforation majorly follows gas diffusion mechanisms. Micro-perforated films with one and three perforations are expected to provide ample O₂ and CO₂ equilibrium concentrations.

Micro-perforated Films Market: Drivers and Restraints

Flexible films offer a protective function against an extensive range of factors; however, some products need the ability to breathe. Micro-perforation technology offers a solution to the breathability issue of flexible films. These films are penetrated with grids of pin-sized holes, thus increasing the functionality and shelf life of a varied range of grocery, medical, and commercial products. Thus, rise in need for increased shelf life of products in end-use industries such as medical and food is expected to drive the micro-perforated films market during the forecast period. However, restriction on the usage of plastic products for food & beverage applications is likely to restrain the market during the forecast period.
