4 Mil Thickness Advantages
The 4 mil gauge represents a significant upgrade from standard 2 mil bags for applications requiring enhanced durability. This thickness excels in environments where bags must withstand rough handling, extended storage periods, or contact with abrasive or sharp-edged contents. The heavier gauge also provides superior moisture barrier properties and maintains structural integrity under load, reducing product loss from bag failure.
