Kite's embossed vacuum bags are made from a 75% PE and 25% nylon material and consist of one smooth transparent side and one dotted embossed side, both of 90 micron thickness. The edges are pre-sealed aside from one short side which has an opening ready to be filled with produce before being secured with one of our vacuum sealers or chamber machines. There is an easy tear incision at the pre-sealed end for greater convenience, efficiency and satisfaction when the item reaches its destination and can be easily accessed. When activated by machine, these vacuum bags demonstrate their unique feature of having all the internal air removed and hence, reducing the size of the parcel down to the smallest possible dimensions. The vacuum packed contents are tightly encased and unlikely to move about inside a mailer.
