In 1933 American bakeries for the first time produced more sliced than unsliced bread loaves. Some mass-produced sandwich breads are sliced before being packaged, while others are packaged unsliced. It is sold packaged and either pre-sliced or unsliced, in several varieties. A side of unsliced bacon is known as "slab bacon". The cheese was provided monthly, in unsliced block form, with generic product labeling and packaging.
