Buying Guide: Key Purchase Considerations
- Bag thickness (mil or micron): Thicker bags resist punctures but can be stiffer to handle; select based on waste type and handling.
- Sealing method: Star seal designs reduce leaks; twist ties aid quick closure, especially for large jobs.
- Size fit: Ensure 38×46 inches or similar dimensions fit your cans; check height and width for yard waste or commercial bins.
- Quantity: For frequent use, bulk options (125–250 counts) reduce replacement frequency; for small tasks, 25–50 counts may suffice.
- Material quality and sourcing: US-made bags can offer consistent material quality; consider vendor reliability for heavy-duty needs.
- Special features: Gusseted bottoms increase load capacity; clear vs. black bags can affect visibility of contents or odor handling.
