Low weight of vacuum bag as to the content;
Low in cost by several times in comparison with glass or metal packaging;
Zipper (zip-lock, zip-clip) allows to repeat operations of product pull off and hermetical closure of the bag every time. And thus product time-of-use can be extended without loss of quality.
Co-extruded bags of non-oriented polyamide with polyethylene are soft to the touch, nearly non-rustle and their vacuum welds could slightly fold. Such bags can easily fit any product while vacuum processing and have excellent resistance towards puncture and mechanical impacts when over 90 µm.
