New-Bitmap-Image-10KEEP-IT-FRESH Master batch can be used to produce plastic bags and containers with special properties of shelf life enhancement of fresh fruits, vegetables and flowers from 40% to 400%.

Fresh fruits, vegetables and flowers start to ripen after harvesting and during the ripening process, these products release ethylene gas. This ethylene gas, when in the package increases the ripening rate of the fresh product.  Hence, the ripening process is accelerated which results in faster rotting of the fresh product. The ethylene gas produced works as an auto catalyst for ripening, which in turn produces higher sugar levels causing microbial spoilage of the products.

The plastic products 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 product.

The Master Batch packaging products have been shown to increase shelf life of bananas by up to 5 times, and improves the shelf life of tomatoes by up to 3 times.

Tests performed on the tomatoes show that the product kept in the open started to rot in 5 days, where as the ones in the KEEP-IT-FRESH bags were good even on the 10th day. Comparatively, tomatoes kept in generic plastic bags developed black spots and mold by the 6th day.
