摘要:
This invention relates to the use of a single "hold-out" coating layer including a colloidal copolymer applied by the paper machine on the press-applied barrier side of a paperboard substrate. Such structures of this type, generally, allow paper machine with only one coater on the barrier side to apply a sufficient coating for the desired hold-out.
