Mil Thickness
Measurement of container wall thickness where 1 mil equals 0.001 inches.
Mil thickness measures container wall thickness using the imperial unit where 1 mil equals 1/1000 of an inch (0.0254 mm). Standard 5-gallon pails typically have 70-90 mil walls, while heavy-duty industrial pails often feature 90-110 mil construction. Thicker walls (90+ mil) provide significantly greater durability, improved stacking strength (supporting 6+ units high), enhanced chemical resistance to aggressive solvents, and longer container lifespan. The relationship is non-linear: 90 mil walls provide roughly 30% more protection than 70 mil walls. Professional buyers typically specify mil thickness based on intended use, stacking height, and hazmat requirements.
