​PEAKfresh is modified atmosphere packaging (MAP) made specifically for fruit and vegetables as well

as cut flowers and plants. With a natural mineral embedded in our products, we are able to modify the
composition of the air surrounding the packaged item in order to extend the initial fresh state of the
product. PEAKfresh has long been used by growers, shippers and retail chains to preserve the
freshness of produce during transit and storage. Most recently, NASA began using PEAKfresh to

extend the life of produce sent to and consumed by the astronauts at the International Space Station. 


   Depending on the variety to be packed, plums can be
   successfully stored under refrigeration for five to seven weeks.
   In the latter storage period, there may be some loss of flavor
   and the start of flesh browning. Variety and local growing
   conditions, dictate the application of various sprays and dips
   for bacteria control.

   Recommended Post Harvest Temperatures
   0ºC (32ºF) 90% – 95% relative humidity

   Packaging Method:
   Again depending on variety and local experience, plums are packed into 5 kg and 10 kg PEAKfresh bags that are
   folded closed at the top. Using this method requires very careful handling of cartons to avoid bruising and fruit
   damage. Plums that are packed in flexible tray apertures are best covered with a pre-cut sheet of PEAKfresh film.
   This method of packaging will maintain a reasonable level of humidity and provide some control of ethylene gas.
   A similar application using PEAKfresh bubble film with the PEAKfresh film covering the plums has the added
   advantage of buffeting protection. Boxed storage of plums in PEAKfresh carton liners should be quality checked
   around three weeks.
   Storage Temperatures:
   0ºC (32ºF) 90% - 95% humidity
   Important Please Read:
   All recommendations for the use of PEAKfresh products are given in good faith and based on proven field
   experience. Packaging method storage temperatures and humidity levels, transit and destination conditions are
   factors likely to affect the performance of PEAKfresh products and no liability for indirect or consequential damage
   can be accepted. We recommend that PEAKfresh products be trialed under local conditions before introduction to
   large scale commercial applications.
