That's an excellent question for anyone managing waste in high-traffic outdoor areas. For a large commercial outdoor trash bin, you need liners that are tough, weather-resistant, and reliable. Here’s what to look for:
First, prioritize thickness and material. Look for heavy-duty, low-density polyethylene (LDPE) bags with a thickness of at least 3 mils, but 4-6 mils is ideal for demanding outdoor use. This gauge resists punctures from sharp debris and withstands sun exposure and temperature swings.
Leak-proof features are non-negotiable. Choose bags with star-sealed bottoms or gusseted seams to prevent tears and contain liquids. For bins collecting food waste or liquids, consider leak-proof liners with a built-in absorbent core to control spills and odors.
Size and fit are critical. The liner must be large enough to fully cover the bin's interior with ample overhang. A bag that's too small will slip in, while one too large is wasteful. Measure your bin's dimensions and choose a corresponding liner size (e.g., 55-gallon bags for standard commercial bins).
Finally, consider drawstrings or tie handles for secure closure, which makes removal safer and cleaner for maintenance staff. Investing in quality industrial-strength liners reduces the risk of bag failure, messy clean-ups, and environmental contamination, proving more cost-effective over time despite a slightly higher upfront price.
