Controlling the atmosphere around a food product is key to extending product shelf life and maintaining an attractive customer presentation. Our experts understand the importance of gas flush packaging, a process that replaces package headspace with a beneficial gas or mixture of gases that will dramatically slow bacterial growth and oxidative reactions.

  • With Modified Atmosphere Packaging, longer quality shelf life results in fewer product returns, less waste and higher customer satisfaction, and allows for optimisation of production and distribution.
  • While Controlled Atmosphere Packaging (CAP) allows products to be stored for up to one year at optimum gas concentrations for quality retention. This allows extended marketing for seasonal crops, enabling the grower and processor to earn higher profits while the consumer enjoys greater availability of high quality fruits and vegetables.
