US Patent:

8158230, Apr 17, 2012
Filed:

Nov 6, 2007
Appl. No.:

11/935767
Inventors:

Edwin C. Culbertson - Taylors SC, US
Kenneth J. Muschelewicz - Easley SC, US
Assignee:

Mitsubishi Polyester Film, Inc. - Greenville SC
International Classification:

B32B 9/00
B32B 33/00
B32B 7/12
B42D 15/00
US Classification:

428 401, 428 421, 428354, 428915, 428916, 283 72, 283 82, 283 98
Abstract:

A tamper evident composite film is disclosed. The composite film contains a first film layer made from polyester adjacent to a second film layer made from a polyolefin, such as a low density polyethylene. If desired, the composite film can further include a third film layer positioned on the opposite side of the second film layer. The composite film is produced through a coextrusion process. In one embodiment, the composite film can be biaxially stretched prior to use. The composite film is constructed so that the first film layer will delaminate from the second film layer when the composite film is tampered with or otherwise mishandled.

Primer Coating Composition And Polymeric Film Coated With Primer Coating For Silicone Release Applications

US Patent:

52983250, Mar 29, 1994
Filed:

Feb 10, 1993
Appl. No.:

8/015745
Inventors:

Edwin C. Culbertson - Greer SC
Assignee:

Hoechst Celanese Corporation - Somerville NJ
International Classification:

B32B 2734
B32B 2736
US Classification:

428336
Abstract:

The present invention describes a polymeric support film coated with a primer coating composition and overcoated with a silicone release coating, thereby forming a silicone release film. Silicone release films are well known and serve as temporary supports for an adhesive or tacky surface such as for labels, pressure sensitive tape etc. The primer coating composition, before dilution with water, comprises from about 25 to 75% by weight of a glycidoxy silane and from about 75 to 25% by weight of a copolyester. The copolyester comprises from about 65 to 98 mol percent isophthalic acid; from about 0 to about 30 mol percent of at least one aliphatic dicarboxylic acid; from about 2 to about 20 mol percent of at least one sulfonate group attached to a dicarboxylic nucleus; and about 100 mol percent of glycol having from about 2 to 11 carbon atoms. Typical glycidoxy silanes that can be employed in the primer coating composition include glycidoxypropyltrimethoxysilane.

US Patent:

46422633, Feb 10, 1987
Filed:

Dec 18, 1984
Appl. No.:

6/683435
Inventors:

Edwin C. Culbertson - Greer SC
Assignee:

American Hoechst Corporation - Somerville NJ
International Classification:

B32B 2708
B32B 2736
US Classification:

428336
Abstract:

Plastic films having improved antistatic properties are disclosed having a continuous coating on at least one surface of the film based on a composition comprising a mixture of: (a) a polymeric binder, and (b) a quarternary ammonium salt having the formula: ##STR1## wherein: R is a lower alkyl group having 1 to 3 carbon atoms; R' is an alkyl or alkenyl radical having from about 8 to 20 carbon atoms; and X. sup. - is an anion. The antistat coating composition may be applied to the film material at any suitable stage during manufacture, i. e. , after extrusion of the sheet material or before, during or after orienting the sheet. The resultant film is found to possess markedly enhanced antistat properties, good clarity, good slip properties, reclaimability and adhesive properties at higher binder levels rendering it suitable for the application of other coatings.
