Abstract
A body to be packaged is suspended on filaments in an upwardly open porous mold which is lined with a gas-pervious sheet material. The mold is capped and a synthetic resin is introduced therein and expanded, the air in the mold being displaced out through the mold walls, to completely encapsulate the body. The supporting filaments, extending from the package so formed can be drawn across each other to cut an opening in the package permitting the packaged body to be removed. The sheet material covers the outside of the package, being integral therewith, and protects the package while permitting it to be written on.
