Package for preserving respiring produce and method

A package for preserving respiring produce contained in the package wherein the package defines a package volume for containing a portion of the respiring produce and a package atmosphere, which package comprises:

• a packaging material which comprises a Biaxially Oriented Poly Ethylene (BOPE) or a Mono Directed Oriented Poly Ethylene (MDOPE)-containing polymer film with a haze of at most 10, as determined by ASTM D 1003,
• said polymer film being provided with one or more perforations enabling gas exchange with atmosphere surrounding the package to form the package into a Controlled Atmosphere Package (CAP);
• wherein:
• the package has a package carbon dioxide transmission rate (CO2TRpack)
• the one or more perforations provide a perforation carbon dioxide transmission rate (CO2TRperf) such that the package carbon dioxide transmission rate (CO2TRpack) is a sum of the perforation carbon dioxide transmission rate (CO2TRperf) and a material carbon dioxide transmission rate (CO2TRmat) of the packaging material (CO2TRpack=CO2TRperf+CO2 TRmat) and
• the CO2TRpack is at least 1000 ml/24 hrs per 100 gram of the respiring produce to be packed.
