Abstract: A clamshell container for herbs and produce includes a base and front cover connected by a hinge, forming an enclosure. The base has first and second male grooves, with the first male grooves configured as ramps to slide a recyclable sleeve into position, and the second male grooves positioned to secure the sleeve in a snug fit around the clamshell container. The sleeve provides a surfaces for branding and labeling. The front cover includes first and second female grooves that align with the male grooves. A stack of containers aligns through male grooves on one container engaging female grooves on another, maintaining stability and preventing displacement. A method includes filling the container, sliding on the sleeve, and stacking containers via the grooves, ensuring secure and sustainable packaging for herbs and produce during transport and storage.
