Patent ID: 7108909

Claim:
A method of labeling a cryogenic specimen storage container prior to storage at a cryogenic temperature of about −80 degrees C. or lower, said method comprising the steps of: (a) providing a sized portion of an adhesive vinyl label, wherein said label comprises a waterproof, soft flex vinyl facestock material wherein said vinyl facestock material comprises polyvinyl chloride, having a waterproof machine-printable upper surface, and a waterproof pressure-sensitive adhesive-coated lower surface, wherein said vinyl facestock material comprises a substantially non-mobile plasticizer agent, and said facestock material is capable of being stretched at room temperature at least 10% in both the machine and transverse directions without breaking when subjected to a tensile stress of less than 1200 psi; (b) marking said upper surface to identify said container, wherein said marking resists ice and moisture that typically condense on said container when it is transferred from cryogenic storage conditions to ambient conditions, and (c) attaching said sized portion of said label to said container.
