How do you calculate packaging count per shift?

Multiply boards per pallet by pallets per shift for gross output, then multiply by packaging uptime and packaging yield. With 4, 480, 90% and 97% you get 1,920 gross and 1,676 good units.

What is a good packaging uptime for a drywall line?

Target 92-96% on banding and wrapping; the 90% default already costs 192 units per shift. Below that, packaging risks becoming the constraint behind the stacker.

Why does packaging yield matter if the board already passed earlier?

Units can still be rejected for crushed corners, banding damage or wrap faults at packaging. That late 3% yield loss (~52 units here) scraps already-finished product.

How do I keep packaging from bottlenecking the line?

Compare this good output to your stacker's good output. If packaging good units fall below stacker output, recover packaging uptime and yield before the line backs up.

What's the difference between gross and good packaging count?

Gross (1,920) assumes packaging never stops and nothing is rejected. Good (1,676) subtracts 192 units of uptime loss and 51.8 units of yield loss, the realistic shippable count.

How much does closing the uptime gap add?

Lifting packaging uptime from 90% toward 95% recovers roughly 95 units per shift in this setup, usually cheaper than speeding up the palletizer.

Packaging Count Calculator

Packaging Count estimates how many good packaged units a drywall plant's bundling and palletizing line can deliver per shift once packaging downtime and reject losses are removed from the raw count. Packaging supervisors and logistics planners use it to size the shrink-wrap and banding station, schedule truck loading, and confirm the packaging end can keep pace with the stacker upstream. When banding stops, film runs out, or a unit is rejected for a damaged corner, finished product backs up onto the line. This calculator turns rated packaging speed into a defensible good-units-per-shift number for the warehouse.

What this calculator does

Estimate board packaging output for a shift by combining boards per pallet, pallets per shift, packaging uptime, and packaging yield.
Use it when planning a shipping schedule and you need to confirm the packaging line can meet the pallet count commitment before the dock window closes.
It computes good packaged units per shift by multiplying boards per pallet and pallets per shift, then derating by packaging uptime and packaging yield.

Formula used

Gross packaging output = boards per pallet x pallets per shift
Good pallets per shift = gross output x packaging uptime x packaging yield

Inputs explained

Boards per pallet:
Pallets per shift:
Packaging uptime:
Packaging yield:

How to use the result

Use it to set packaging shift targets, check that packaging keeps up with stacker output, and quantify what banding stoppages and damaged-unit rejects cost.
It assumes a steady palletizing rate and independent uptime and yield factors, so it won't model surges where the packaging line is starved or flooded by the stacker feeding it.
