Constructs including a blank and a body formed from liquid molding material are provided. The blank may be hermetically sealed to the body. For example, a mold assembly may injection mold the blank to the body. The mold assembly may include a male mold and a female mold that cooperatively define a first cavity and a second cavity. The first cavity may receive a peripheral margin of the blank and the second cavity may receive the remainder of the blank. Liquid molding material may be directed into the first cavity to form the body of the construct. The liquid molding material may be directed into the first cavity in a manner that avoids bending the peripheral margin of the blank such that a tight seal is established between the blank and the body of the construct and the blank retains a planar configuration.
