example

[0069] In order to evaluate various aspects and characteristics of the present invention, the pressure-sensitive label construction using the microporous polypropylene according to the present invention was die-cut with dimensions of 85 cm×85 cm and 100 cm×100 cm, and the label sample was applied to the blood bag.

[0070] As a comparative reference, a pressure-sensitive structure of stretched non-porous polypropylene was die-cut with dimensions of 85 cm×85 cm and 100 cm×100 cm, and applied to the blood bag.

[0071] As a comparative reference, a pressure-sensitive structure made of cast non-porous polypropylene was die-cut with dimensions of 85 cm×85 cm and 100 cm×100 cm and applied to the blood bag.

[0072] As a comparative reference, the pressure-sensitive structure using WS paper was die-cut with dimensions of 85 cm×85 cm and 100 cm×100 cm, and applied to the blood bag.

[0073] As a comparative reference, all samples were left at room temperature for 15 minutes. Then, the blood ...

Embodiment 1

[0084] Example 1: A label suitable for use on blood bags, the label comprising a microporous polypropylene film (which defines a first side and an inverted second side) and the first side and Adhesive on at least one of the second sides.

Embodiment 2

[0085] Embodiment 2: According to the embodiment of embodiment 1, wherein after being exposed to a temperature of 121° C. for 30 minutes, the shrinkage characteristic of the label approximately matches the shrinkage characteristic of the blood bag.
