These look good and hold the perfect amount of cherry tomatoes and sugar snap peas, but they pop open SO EASILY. Even knocking over a stack and the Disposable Clamshell Container falling a couple of inches, the containers will pop open, but they do the job and they are very cost effective! We use these containers to package produce like cherry tomatoes, small plums, grapes, blackberries. If we didn't put these items in Fruit Clamshell Packaging Box, they would be just mush by the time they were distributed. The Plastic Strawberry Clamshell Packaging makes the blank into a tool with a specific shape and size under the action of external force. It is widely used in punching, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products.
