Food anaerobic shrink film

U.S. companies use a co-extruded anaerobic shrink film, which is used in conjunction with the Deltap horizontal filling and sealing machine and has a waterproof drop forming property. In this package, with 70% nitrogen and 30% carbon dioxide, its life can be extended to 30 days. Under refrigerated conditions, the residual oxygen in the bag is less than 0.4%, so that the color and aroma of the meat remain unchanged.
