Kit for preparing blister packages

A vapor-tight package has a deposit comprising nonmetallic, microwave-absorbing particles such as graphite dispersed in nonmetallic binder. When heated in a microwave oven, heat built up in the particles may soften and weaken the underlying packaging material, thus venting the package. When the deposit itself is impervious to vapors, it can be positioned over an opening in the package, and the heat only needs to soften and weaken the deposit to vent the package.
