Paper Making and Printing
Clothing and garments, which featured mainly in the last chapter, provide suitable protection against the elements for humans but most manufactured items, especially the fragile and delicate, require protective transit packaging to make sure they reach their destination intact. One of the most common types of such packaging is corrugated cardboard which is usually made from reprocessed paper. Double-sided board consists of two outer sheets spaced apart by an undulating sheet which is glued alternately to the insides of the two outer sheets. Because of its inherent strength, which is produced by the closed box construction, it is remarkably effective. A single-sided board is also made which is less rigid and conforms more closely to the object to be packed.
