TamperAlert hinge protrudes outward when torn, alerting the customer that the container has been opened. Hinge remains attached to the container, meaning no loose plastic pieces and therefore no littering. MicroTrim edge contributes to tamper-resistance by inhibiting the ability to lift up the lid from the base without tearing the hinge. 360 degree leak-resistant perimeter seal completely seals entire tray for maximum freshness and to prevent leaks. Recessed stacking platform provides greater stability of merchandising displays. Offset opening tabs and lift and hold embossing makes SafeSeal bowls easier to open. Crystal clear container with minimal sidewall ribbing. Food Container Type: Base/Lid Combo; Material(s): PET - Polyethylene Terephthalate; Material Type: Plastic; Interior Volume Capacity: 12 oz.
