​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. 


   Fresh strawberries are highly perishable. Surface injury and
   respiration rates are common as a result of handling. This type
   of injury can cause rapid deterioration and development of
   decay. Surface injury can be controlled by careful attention to
   handling from harvest to post harvest. Prompt pre-cooling of
   harvested fruit to temperatures of 0°C (32-33°F) will slow down
   the respiration rate thus slowing down the deterioration process.
   By maintaining a temperature control chain through the
   distribution process losses can be greatly reduced. Berries
   generally enjoy high levels of carbon dioxide 10% – 30% as this
   atmosphere slows down the respiration rate and reduces the
   activity of decay causing organisms.

   Recommended Post Harvest Temperatures
   0ºC (32ºF) and 90-95% humidity. Pre-cooling following harvest
   is very important.
   Packaging Method:
   Strawberries are packed in a variety of styles. These styles
   include plastic clam shells of various sizes as well as dry pint
   plastic baskets. It is important that whatever method is used that
   packaging be well ventilated for proper cooling.
   PEAKfresh Benefits:
   When PEAKfresh is used in conjunction with proper handling
   and cooling, a decrease in product deterioration and an increase
   in shelf life can be achieved. PEAKfresh pallet covers offer the
   added protection needed to protect fruits and vegetables.
   PEAKfresh pallet covers keep relative humidity levels high and
   help maintain proper carbon dioxide levels. PEAKfresh pallet
   covers help reduce the moisture condensation when
   temperatures are not maintained properly. This reduction in
   moisture condensation helps to greatly reduce the decay
   process.PEAKfresh pallet covers can be removed for product
   inspection and then reinstalled to continue to protect product.
   PEAKfresh Pallet Cover Installation:
   PEAKfresh pallet covers are easily installed and require little
   labor and no special equipment. Pallet covers can be simply
   opened and pulled over the product to be protected. It should be
   noted that pallet covers should be installed in a manner as to not
   cover the wood or plastic pallet. If pallets are covered, air flow
   could be restricted causing improper air flow.

   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.
