Pac Life for blueberries

Export of Blueberries variety Elliot packed in containers Pac Life Blueberries variety Elliot were packed in containers Pac Life Clear DYNAMIC, on 02-03-2013 with another container trade MAP, in order to compare both on arrival at final destination Shanghai, China.

In front of the current problems of some blueberry varieties that have had recurrent problems in their arrival condition to Asia and the high variability and instability of gases that have other MAP packaging of the market. Life Pac applied engineering in polymers to their packaging, modifying and increasing permeability by incorporating inorganic and synthetic additives (ZEOLITE) to their blades, thus achieving a "selective membrane" with greater ability to adapt to the requirements of blueberries, according status of maturity and storage temperature.

Prior to delivery of pallets to Asia, these were reviewed and monitored his condition and level of atmosphere, finding concentrations of CO2 (%) within the safety zone indicating Pac Life <5%.

Comments from receiver and Pac Life Technical area The main difference was recorded on arrival at destination (40 days after packing), in the bags tested; are the final levels of O2 and CO2 to witness bag being dangerous, to the point of cause intoxication due to a high level of CO2 (> 12%) or anaerobiosis by low levels to 2% of O2. Concentrations out of the normal range for the conservation of blueberries (8 12 O2 / 8 -12 CO2) explain in some cases soft fruit, bad taste and strange odors, product of fermentative metabolism. Pac Life containers showed greater stability in gas exchange, turgid fruit with good flavor and appearance (keeps bloom), highlighting minimal gas variability in relation to the commercial witness.

Chinese Customers and / or receivers have accused problems in past seasons realizing that have received fruits with high levels of rot, soft fruit, estrange odors, and bad taste using other packaging (MAP) options which often determines sales and prices. Therefore, it is vital that the packaging MAP to use, has the technology, chemical physical attributes and qualities that facilitate the adjustment of the fruit against changes in temperature or cold breaks, very common on long trips and sea shipments.
