Abstract: A package of a plurality of plastic film bags, said bags having over comparatively broad surfaces of both the inside and outside of said bags, an effective proportion of an animal repellent comprising methyl nonyl ketone, said repellent having emanated from a comparatively small area of said film while said bags were in the folded condition within said package, said package being sealed and the walls thereof being impervious to said animal repellent and a method of forming the same.

Abstract: Mixtures of 3-phenylpropenal with undecanone-2 act in a synergistic manner to provide an animal repellant of improved effectiveness to discourage scavenging animals, in particular, for animals of the dog and cat families.

Abstract: A method for the production of embossed laminar thermoplastic film structures comprising supplying a first length of a thermoplastic film onto the surface of a patterned roller, portions of which pattern are capable of absorbing infrared radiation, subsequently heating the patterned surface to raise the temperature of the film in those areas which are in contact with the infrared absorbent pattern, and finally superimposing a preheated film onto the film on the surface of the patterned roller to produce a laminar structure bonded together along a plurality of intersecting heat seal lines.

Abstract: A method for the production of laminates comprising oriented thermoplastic film heat bonded to a thermoplastic foam which comprises extrusion of a thermoplastic foam containing a blowing agent which has a plasticizing action upon the foam material and while the extruded foam still contains residual blowing agent, heat welding an oriented thermoplastic film to the foam. Disorientation of the oriented film in accord with the present method is eliminated by virtue of the lower heat bonding temperatures necessary to achieve an effective weld by virtue of the presence of the blowing agent-plasticizer material remaining in the foam.
