Opaque packaging means the product cannot be seen through the packaging from the outside — a design requirement intended to prevent children from identifying contents as candy. Opaque packaging is confirmed required for cannabis products in California, Colorado, Washington, and Oregon. Illinois, New York, Michigan, and Nevada should be verified directly with state regulators before printing, as secondary sources are inconsistent on these states. Opaque laminate films used in flexible stand-up pouches satisfy this requirement in states that mandate it.
