How to choose
- When to go 6 mil: sharp edges, heavy parts over a few pounds, bags reused in bins, or outdoor storage
- Flat vs. reclosable: flat bags are cheaper per bag and heat-seal or tape shut; reclosable bags reopen for counting and kitting
- Don't over-buy thickness: light parts in 6 mil bags cost more for no benefit; 2 to 4 mil covers most small parts
- Size: add about 1 in. to width and length for flat items, more for thick parts
