EVOH AND PVDC HIGH BARRIER SHRINK VACUUM PACKAGING for MATURE AND RIPENING CHEESE PACKING

For mature and ripening cheeses, controlled atmosphere and moisture loss are critical to flavor development and shelf life. EVOH (Ethylene Vinyl Alcohol) and PVDC (Polyvinylidene Chloride) high-barrier shrink vacuum bags offer the ultimate protection for these demanding applications. These multilayer films are engineered to provide exceptional oxygen transmission rate (OTR) control—PVDC delivers outstanding moisture and gas barrier properties, while EVOH offers superior oxygen scavenging in dry conditions. When applied as shrink vacuum packaging, these materials conform tightly to irregular cheese surfaces, eliminating air pockets that promote mold and aerobic spoilage. This secure seal preserves the cheese’s intrinsic humidity, prevents oxidation of fats, and controls ammonia buildup, allowing ripening cultures to work precisely without dehydration or rind damage. The result is extended product freshness, reduced shrinkage loss, and consistent texture and flavor for premium aged cheeses.
