Double-coated pressure-sensitive adhesive tape incorporating a strong, flexible thread

摘要

An improved window insulating kit of the type including a transparent plastic film and a double-coated pressure-sensitive adhesive tape by which a piece of the plastic film can be mounted and stretched taut across a window casement. Excess plastic film can then be trimmed off by pulling a strong, flexible, low-elongation thread that is incorporated into the tape. The thread can be made of highly oriented polymeric filaments and preferably is from 0.08 to 0.4 mm in diameter so that it can cut cleanly through the plastic film.
