Abstract
A method of making a multicompartment reclosable thermoplastic bag having at least two compartments is disclosed. Each compartment has a top, a bottom, two side edges, and two opposing sidewalls joined at the side edges and the bottom. Each compartment has a closure across the top thereof, which are arranged back-to-back and aligned. The compartments are attached together proximate the tops of the compartments, and the bottoms of the compartments are free from being attached to each other. Processes for making such bags from one or more webs are also disclosed.
