摘要:
Apparatus for producing heat-shrinkable packaging with an integrated hand-hold with a circuitous path extending from an input loading/unloading zone, a section where the open portion of a heat-shrinkable bag is sealed shut and creating a container in which an object is enclosed, a section in which heat is applied directly to exposed areas of the plastic film of the package for sealing the package, and a section of path enabling the package to cool; trolley apparatus for supporting the package and engaging the circuitous path for movement of the package along the circuitous path; and protrusions positioned along the circuitous path for propelling the device along the designated track route.

摘要:
Methods are disclosed for producing finished packages. A bag is made from heat-shrinkable material and has a container portion with an open end and a closed end, and an integrated handle portion. An object to be packaged is placed through the open end of the bag into the container portion, and the open end is sealed. Heat is then applied to the bag while insulating the integrated handle portion so that a finished package is obtained with an unshrunken integrated handle portion and a container portion that is shrunk around the object.
