Standard Sheet Sizes for Trade Pulp?

Thanks, but I'd found that and another paper-industry site giving dimensions of finished paper products, but no indication of the size of trade pulp sheets. My suspicion is that there's no formal standard, but that pulp mills do have standard practices. Pictures I've been able to find show bales of trade pulp sheets stacked on pallets, and it looks like the area of the pallet will accommodate four bales. Now all I have to do is find out what size pallets they're using...

"One of the machines that are used to thicken wood pulp is called a "Wet Lap" machine. They are typically about 96 inches wide and the resulting sheet can be slit and cut into 4 ft X 4 ft sheets. In a mill that processes the pulp to paper, the sheets are not dried but stored in wet bales. (drying is expensive the wet pulp is about 60% or higher moisture).

Pulp that is thickened to be sold as pulp is usually dried before cutting and sold dry. Most experience I've had with pulp laps, the laps were 4 ft X 4 ft. However, I've been inactive in the paper industry for more decades than I want to admit and standard sizes may be different now."

This is extremely helpful, both in giving the specific dimensions that I'm looking for and introducing me to the correct terminology for these goods and the machines used in making them. Thank you!

Check with your customer the one or many that are accepting your pulp product.

This is a preliminary design based on making a value-added product from waste. It's a supply-side project, and it's completely new - nothing of the sort is currently being done. It is far too early in the process to identify a customer or customers, so unfortunately we don't have the option of seeking their guidance. For now, we just have to hew as closely as possible to current practice of the paper trade in general.

I stand informed.. thanks.
