Sampling control seals for food and pharma use an adhesive approved for use with foodstuff according to FDA guidelines. These labels provide a reliable seal that will prevent the products of a container from leaking out after sampling. These labels are constructed of an aluminum back with a paper top label, creating a hermetically sealed container, ideal for use with food, pharmaceuticals, cosmetics, and even frozen goods. These labels can be written on with ball-point pen, pencil, or marker and used to provide quality control details at the time of sampling such as date, name, and contents. These labels are available in two size options and five printed color options — red, yellow, blue, green, and black — as well as a white unprinted option. Use the 06040-90 dispenser for the 95 x 95 mm labels and the 06040-91 dispenser for the larger 150 x 150 mm labels.
