The commercial practice for the purchase of baled postconsumer plastic is a negotiation between buyer and seller on bale preparation, included items, prohibited items, and other considerations. APR provides model bale specifications as starting points for the actual mutually acceptable definition of what will be accepted by the postconsumer bottle bale buyer. Buyers and sellers are invited to negotiate changes, deletions, and additions as are appropriate.

The model bale specifications do not imply fitness for use or assurance of commercial acceptance. The documents do cover the typical issues to be addressed in a bale specification and do include typically acceptable conditions.
