Abstract
A sterilizable package having a plastic member marginally heat sealed to a paper member to which is applied indicia that changes color upon sterilization (gas and/or steam) on the inside of the package. The indicia is located in or near the marginal heat seal and is segregated from the package interior to prevent the package contents from covering or being contaminated by coming in contact with the indicia by heat sealing the plastic member to the paper member in the area of the indicia. The indicia can be located within the area covered by the marginal heat seal or within an unsealed area in the area covered by the marginal heat seal. The indicia can also be located interiorly of the marginal heat seal for example at a corner or angle formed between adjacent seals with the plastic member being heat sealed to the paper member in the area surrounding the indicia.
