ABSTRACT:
An improved multi-channel transparent jacket to accommodate film strips is disclosed. The jacket is constituted of top and bottom rectangular panels of flexible plastic material and ribs formed of plastic or other adhering material in situ along parallel lines between the panels and integrally bonded thereto to maintain the panels in spaced relation and to define open-ended channels whose width is substantially equal to the width of the strips. The thickness of the ribs is substantially equal to that of the strips. Improved bonding of the ribs to the panels is accomplished by striating the panels to increase the surface area within a given width available for bonding. In one embodiment, an ultrasound hammer is used in conjuction with a specialized anvil to striate the panels.
