发明名称 Method of forming a sterilizable package with tear-off indicators
摘要 A sterilizable package or pouch is made from a plastic member, generally transparent, which is marginally heat sealed around three sides to a paper member so as to leave an opening at one end for inserting the package contents. The paper member has a portion which extends beyond the area to be enclosed by the marginal heat seal when completed. This portion bears indicia, generally printed on the paper, that changes color upon sterilization (either steam or gas sterilization). The indicia bearing portion is adapted to be separated from the package and inserted therein together with the package contents before the marginal heat seal is completed and the package contents are sterilized.
