Recently PerfoTec conducted a trial to examine the possibilities to extend shelf life for tulips in PerfoTec MAP LinerBags (Modified Atmosphere Packaging). Why extend the shelf life of tulips? Well think about the possibilities such as sea transport instead of transport by air and bulking 1 or 2 weeks before special days like valentine or mother’s day.
PerfoTec is proud to announce that a remarkable and successful trial has been conducted. The goal has been reached: there is a significant difference between the tulips packed in PerfoTec LinerBags and the control group (conventional packed tulips). Tulips packed in PerfoTec LinerBags without water for 28 days still meet all the fresh flower requirements and guarantee +7 days of vase life for the consumer. The control group didn’t develop and the flowers stayed closed and decolored during vase life as the result of dehydration and ripening of the tulips during storage.
How does the PerfoTec LinerBag work?
Due to the properties of the PerfoTec LinerBag and the micro-perforation that is applied, a perfect atmosphere to extend the shelf life of the tulips is created. Too much CO2 would damage the flowers, with the best example being decolorization. In the PerfoTec LinerBags they can reduce the O2 to a lower level than usual without increasing the CO2 to harmful levels.
Besides “controlling” the gas levels, PerfoTec was able to prevent dehydration and bring the weight loss down to only less than 1% while the conventionally stored tulips lost almost 10% of their weight.
All products, including the control tulips, were stored during this test at 2°C for 28 days followed by 3 days of storage at 8°C with water in the bucket. Afterward, the flowers were put on a vase with water at 20°C for +7 days to evaluate vase life.
The conclusion of this trial brings a lot of advantages for the tulips and the rest of the flower industry. As mentioned before, the “PerfoTec Tulips” performed better than the control tulips (who didn’t perform at all). Image the possibilities now that Tulips can survive without water for 28 days when they are packed with the PerfoTec LinerBag.
