ABSTRACT:
A sterile pack blank is provided which comprises an enclosure determined by a substrate of predetermined porosity and a discrete plastic film overlying the porous substrate. The film and porous substrate are adhesively connected by a cohesive or self-sealing adhesive. The porous substrate is printed with a continuous adhesive track, while substantially an entire surface of the plastic film is adhesive coated. An end flap of the film is folded back upon itself along a fold line to provide access to the enclosure interior. After introduction of an instrument into the enclosure, the film end flap is hingedly connected to the substrate, along respective adhesively coated areas thereof, according to the sealing method of the invention. The adhesive is characterized by the fact that it is self-adhering. Therefore, only interfaced areas of the film and substrate that are respectively coated with the adhesive may be adhesively connected. The adhesive coating on the film is further characterized by a predetermined tack value for thereby providing for secure sterile delivery of an instrument from the pack. The porous substrate is provided, respectively, with exterior and interior sterilization indicators. The indicators comprise respective pairs of steam and ethylene oxide sensitive inks. The exteriorly located indicators are immediately sensitive to the sterile ambience of the pack, while the interiorly located indicators are sensitive to a sterile environment within the pack enclosure.
