Problems solved by technology

However, label defects can occur during application, during labeling operations for simple or complex shaped bottles, or in post-application processes
These misapplied labels result in high waste or additional processing steps which can be costly

Embodiment 1

[0108] The pressure sensitive shrink labels were constructed of a 3 mil thick low density polyethylene multilayer shrink film named CorrTuff from Sealed Air. The film was coated with acrylic emulsion adhesive S692N from Avery Dennison. The adhesive was applied on a coated paper Glassine BG-40 silicone release liner. The labels are extra large, having dimensions of approximately 5 x 3.5 inches, which is 20% larger than the industry standard recommended label size for the bottle to which the label is applied.

[0109] Compound curve 15 oz Johnson & Johnson Baby Lotion bottles were filled with water, capped and processed through a Label-Aire 9000 Series labeler at 100 bottles per minute (BPM). The labeler features dual feed screws with speed-matched upper and lower conveyor belts, a Label-Aire 2115-CD labeler head, and a high torque stepper motor drive. The label is pressed down with a walking beam type wiping device that provides a direct, center-out force to direct entrapped ...

Embodiment 2

[0112] A pressure sensitive shrink label consisting of a 2 mil thick polypropylene multilayer shrink film designated CZPA 200 from Innovia was applied to the bottle with compound curves following the method described in Example 1 . After initial wiping, medium-sized protrusions formed. High velocity hot air heats the bottle and label to 100°C. Protrusions shrink and rub flat easily after application of heat. Burst does not recover after aging.

Embodiment 3

[0114] A pressure sensitive shrink label consisting of a 2 mil thick polylactic acid monolayer shrink film designated EARTHFIRST PLA from Plastic Suppliers was applied to the bottle with compound curves following the method described in Example 1 . After initial wiping, medium-sized protrusions formed. High velocity hot air heats the bottle and label to 70°C. Protrusions shrink and rub flat easily after application of heat. Burst does not recover after aging.

Abstract

The invention provides a pressure sensitive shrink label. A label for application to a surface having at least one compound curve is provided. The label comprises a heat shrinkable film having an inner surface and outer surface and a layer of pressure sensitive adhesive on the inner surface of the heat shrinkable film.

Description

[0001] This application is a divisional application. The filing date of the original application is April 4, 2008, the application number is 200880018553.2 (PCT / US2008 / 059397), and the title of the invention is "pressure-sensitive shrink label". [0002] Cross References to Related Applications [0003] This application claims priority to provisional applications US Serial No. 60 / 910,282, filed April 5, 2007, and US Serial No. 60 / 938,019, filed May 15, 2007. This provisional application is hereby incorporated by reference in its entirety. technical field [0004] This invention relates to pressure sensitive shrink labels. More particularly, the present invention relates to pressure sensitive labels having excellent conformability to containers having complex shapes and methods of applying these labels. Background technique [0005] It is common practice to apply labels to containers or bottles to provide information such as the supplier of the container or the contents of ...
