Description
They ethylene gas produced works as a auto catalyst for ripening which in turn produces higher sugar levels causing microbial spoilage of the fruits.
The plastic articles produced by using KEEP-IT-FRESH MB absorb the harmful ethylene gas produced hence slowing the ripening and rotting process and increasing the shelf life of the packed produce.
The film produces shows upto 4 times increase in the shelf life of Bananas kept without packaging and improves the shelf life of Tomatoes by upto 3 times.
Tests performed on the Tomatoes show that the tomatoes kept in open started to rot in 5 days where as the ones in the KEEP-IT-FRESH bags were good even on the 10th day compared to the ones in generic plastic bag.
