Apple-Pomace Paper Packaging at a 20% Blend: Barrier and Scale-Up Gates Beyond the Strength Headline
An early laboratory-handsheet project reported roughly 50% increases in both tensile strength and tensile stiffness when 20% apple pomace supplemented wood pulp. This article keeps that result at proof-of-concept scale and turns the missing feedstock, papermaking, barrier, food-contact, recyclability and line data into a pilot approval table.
