US Patent:

49619780, Oct 9, 1990

Filed:

Mar 6, 1989

Appl. No.:

7/318863

Inventors:

Anthony J. Doheny - Natick MA
James R. Noonan - Watertown MA

Assignee:

The Kendall Company - Boston MA

International Classification:

B32B 308
B32B 706

US Classification:

428 40

Abstract:

A closure device for shrinkwraps comprising a high temperature-resistant, flame-resistant and dimensionally stable backing layer, a cross linked, high temperature-resistant, shear-resistant, and flame-resistant pressure sensitive adhesive applied to one surface of the backing layer; a heat-shrinkable film dimensionally smaller than the pressure sensitive adhesive layer positioned on the adhesive layer so as to maintain a peripheral area of exposed pressure sensitive adhesive; and an optional release liner applied so as to protect the exposed pressure sensitive adhesive layer from premature and unwanted contact prior to use.

Appl. No.:

7/445505

Anthony J. Doheny - Natick MA

Assignee:

The Kendall Company - Mansfield MA

International Classification:

B29C 3510

US Classification:

264 22

Abstract:

Novel processes for preparing a heat shrinkable film by first forming a polyolefinic film on a three-roll calender in which the second and third rolls rotate at about the same speed and the first roll rotates at a slower speed, the top roll is heated to a temperature above the melting point of the polyolefinic material, the middle roll is heated to an elevated temperature below its melting point, and the bottom roll is chilled relative thereto; thereafter subjecting one surface of the resulting film to irradiation from a low energy electron beam at a voltage such that the irradiation dose at the half-depth of the film is approximately one-half the dose at the irradiated surface and at a current to film surface speed ratio such that the surface dose would effect crosslinking sufficient to impart to said film a 100% modulus at 150. degree. C. of from about 10 to about 100 pounds per square inch, if the dose at any depth in the film were substantially equal to the surface dose; and then subjecting the opposed surface of the film to irradiation from a low energy beam at a voltage and at a current to speed ratio substantially equal to that in the preceding step, such that the 100% modulus at 150. degree. C. of the film as a whole is about 10 to about 100 pounds per square inch and the film is characterized as being substantially uniformly crosslinked throughout its thickness.

International Classification:

C09J 702

US Classification:

428345

Abstract:

Novel processes for preparing a heat shrinkable film by first orienting the film and thereafter irradiating a major surface of the oriented film with low energy radiation to effect differential crosslinking throughout the thickness of the film, the opposed surface of the film being characterized as being substantially non-crosslinked; and films and tapes prepared thereby.
