Bulk is a key term in paper manufacturing that refers to the thickness and sturdiness of paper products. When someone mentions "bulk" in paper production, they're talking about how thick or puffy the paper is compared to its weight. Think of it like comparing a fluffy bread to a dense one - they might weigh the same, but the fluffy one takes up more space. This property is crucial because it affects how the paper feels, how well it prints, and what it can be used for. Different types of paper products need different bulk properties - for example, tissue paper needs high bulk to be soft and absorbent, while printing paper needs moderate bulk for good printing quality.
