Using patented laser technology, Temkin International Inc., a packaging firm
based in Payson, UT, can customize the respiration characteristics of flexible
packaging, effectively prolonging the shelf life of fresh produce by a number
of days, according to a June 18 news release from the company.
"Growers, wholesalers, retailers and consumers all stand to benefit from the
added value, reduced shrink, improved presentation and better eating
quality," the news release said. Temkin's laser micro-perforation technology
helps flexible plastic films create an optimal atmosphere inside the package
by controlling oxygen, carbon dioxide and moisture levels to extend product
The new process is patented by Liz Marston of Windham Packaging and used
by Temkin under a license from Windham. Temkin has run laboratory tests
simulating shipping and store conditions on various produce items and found
that the controlled-atmosphere packaging, customized to specific produce
items, prolongs shelf life.
Temkin's successful tests to date have covered arugula, baby lettuce, bananas,
broccoli, carrots, cherries, grape tomatoes, green beans, herbs, hydroponic
produce, lemons, limes, mangos, pears, peppers, strawberries and other types
of produce. The company offers customers complimentary shelf-life testing.
Every Temkin controlled-atmosphere package is meticulously customized,
according to the news release, to meet the respiration characteristics of each
specific fresh produce item, taking into consideration the weight of the
packaged produce, whether it is whole or cut and the anticipated distribution
