ABSTRACT:
A portable unit useful as a household appliance for making plastic bags from multi-layered plastic films. The unit comprises a housing which includes a compartment for a roll of multi-layered plastic film, a lid for the housing which, when closed, defines an elongated slot with the housing for the withdrawal of the plastic film and a hinge means between the lid and the housing for closing and opening the lid. A wire element is mounted on the upper front edge of the housing and an electric circuit, including a switch, in said housing is used to energize said wire when the lid is firmly closed. A first insulating strip overlies the wire and a second insulating strip in the lid is adapted to firmly overlie said first insulating strip. The lid also includes a channel and a cutting means slidably mounted in said channel for severing the plastic bags, and a post for actuating the switch when the lid is closed.
