| The following OTRs are bulk material properties displayed at 1 mil. You may divide by the gauge (in mil) in order to approximate OTR at a different thickness. | ||

| LDPE (low density polyethylene) |
450 - 500 |
7000 - 8500 |
| The following OTRs are enhanced by coating or metallizing. Therefore, these are not bulk film properties, and total film thickness has little impact on the OTR value. | ||
