The 18x30 dimension at 4 mil thickness serves operations requiring durable, large-format protection. Apparel retailers and dry cleaners use these as garment dust covers for coats, suits, and formal wear during storage and transport.

Industrial operations cover equipment, wrap automotive parts, and protect finished goods during warehouse storage.
Key Features
- 4 Mil Heavy-Duty Construction: Resists punctures from hangers, zippers, buttons, and sharp edges that tear lighter bags
- Seamless Tubing Design: No side seams that can split under stress—stronger than folded-and-sealed alternatives
- Crystal Clear Visibility: Customers and staff can identify contents without opening
- Moisture Barrier: Protects garments and textiles from humidity during storage and shipping
- Virgin LDPE Material: Clean, consistent quality with no recycled content that could introduce contaminants
Thickness Guide
At 4 mil, these bags sit in the heavy-duty category—twice the thickness of standard 2 mil bags. Choose 4 mil when packaging items with hardware (buttons, zippers, buckles), sharp edges, or when bags will experience repeated handling. For lighter applications like temporary dust covers, 2 mil bags offer cost savings. For extreme protection needs, consider 6 mil alternatives.
