A tool for creating a container or tray having various features. The tool comprises a cavity operable to receive a blank. The cavity has at least one sidewall for forming at least one sidewall of the container. A core is operatively connected to the cavity. The core is operable to enter the cavity to least partially form the blank into the container. An injection cavity is for receiving liquid resin and directing liquid resin around at least a portion of the perimeter of the blank. The injection cavity comprises an advanced-flow section and a delayed-flow section. The advanced-flow section has a greater cross-sectional area than the delayed-flow section, and the advanced-flow section is located adjacent the at least one sidewall of the cavity.
