Definition: The folds in paper with parallel folds all run in the same direction, parallel to each other. Parallel folds are commonly used for all kinds of brochures (such as tri-fold), stationery inserted into business envelopes, and other materials. The specific direction of each of the parallel folds determines the type of folding pattern such as accordian or gatefold.
Examples:
Accordian, Zig Zag, and Gatefold are types of paper folds that are all parallel folds.
