Packrift scenario model
Books, Documents, And Flat Goods: High-volume pick line
Flat orders rarely need carton height. The operational question is whether bend and corner protection can be preserved while removing void. This labor-heavy warehouse lane model uses 2,400 monthly orders and a DIM divisor of 139 to compare the current Corrugated carton against smaller protective formats.
What this scenario is testing
This version gives more weight to pack-station time because small seconds-per-order changes compound at volume. The model starts with an item profile of 11 x 8.5 x 0.7 in, 1.35 lb per unit, and 1 unit per order. The current package is 14 x 10 x 4 in with 82 seconds of pack time.
Packrift treats the result as a screening recommendation. It is strong enough to prioritize a pilot, not strong enough to replace invoice analysis, damage tracking, or warehouse observation.
Candidate rule
Use rigid mailers for flat orders only when the product cannot shift and the largest edge stays below the mailer bend threshold.
Assumptions used
- $0.69 per billable pound.
- $18.50 per warehouse labor hour.
- 1.15% current damage rate.
- $28.00 expected replacement or support cost.
Risk checks
- corner crush
- bend resistance
- label scannability
- insertion speed
How to test it
- Time ten consecutive orders in the current package.
- Time ten consecutive orders in the test package.
- Watch whether label placement or sealing changes the apparent labor win.
