Embodiment 1

[0118] Surface energy measurement of treated and untreated polypropylene and polyethylene films

[0119] The total surface energy, the combination of dispersive and polar properties, was measured for six commercially available treated and untreated polypropylene and polyethylene films using the contact angle method. Contact angles were measured using a FIBRO DAT1100 Dynamic Absorption and Contact Angle Tester (Thwing-Albert, West Berlin, NJ) and two test liquids, namely water and diiodomethane. The measured contact angle values ​​were used with Surface Calculator software (version 1.0; Sun Chemical, Parsippany, NJ) to calculate total surface energy, dispersion energy, and polar energy.

[0120]Two treated films were tested as well as four untreated films: 1) 25 μm thick TT-treated biaxially oriented polypropylene (BOPP) film (AmTopp, Livingston, NJ); 2) 50 μm thick (2 mil) Treated polyethylene (PE) film (Exopack, Hoffman Estates, IL); 3) 25 μm thick TTNT untreated BOPP film (...

Embodiment 2

[0125] Adhesion of Commercially Available Solvent-Based Inks to Untreated Polyolefin Films

[0126] On the two untreated polyolefin films described in Example 1 (AmTopp TTNT untreated BOPP film (film 3) and the untreated side of Exopack 2mil (50 μm) PE film (film 5)), using Commercially available solvent-based ink New Craft Magenta XV-98, and polyamide pigment bases 52247-1165G / S Blue and 2217NF-1165 Benz Yew (Sun Chemical, Parsippany, NJ) were printed. Apply using a K Control Coater (RK Printcoat Instruments, Ltd., England) equipped with a standard white (wire bar number 0) meter bar (RK Printcoat Instruments, Ltd., England) ink. The film was dried in an oven at 80°C for 10 seconds.

[0127] Adhesion was measured using the adhesive tape test method. Place a strip along the length of each print Cellophane Film Tape 610 (3M, St. Paul, MN), and press twice with the thumb to ensure a tight bond between the tape and the print. Hold the print with one hand while peeling the t...

Embodiment 3

[0133] Adhesion of commercially available water-based inks to untreated polyolefin films

[0134] On the two untreated polyolefin films described in Example 1 (AmTopp TTNT untreated BOPP film (film 3) and the untreated side of Exopack 2mil (50 μm) PE film (film 5)), using Commercially available water-based inks DPP-166, Aquaverse II, Aquaverse II D / T, AquaPro, and Aquaverse V (Sun Chemical, Parsippany, NJ) were used for printing. The ink was applied using a K motor coater (RK Printcoat Instruments, Ltd., England) equipped with a standard white (wire bar number 0) metering rod (RK Printcoat Instruments, Ltd., England). The film was dried in an oven at 80°C for 10 seconds.

[0135] Adhesion was measured using the adhesive tape test method and rated as described in Example 2. Three tape tests were performed on each print at two different tape removal speeds, fast and slow. The three tests at each speed for each print were averaged to yield the percentage of ink removed from ea...

Abstract

Provided are chlorine-free ink and coating compositions that demonstrate improved adherence when applied to untreated flexible plastic film substrates. The provided compositions eliminate the need for a separate step of pre-treating a plastic film before applying an ink or coating composition. Also provided are methods for producing a printed article using the provided ink and coating compositions and methods of adhering chlorine-free inks or coatings that exhibit improved adhesion characteristics to untreated plastic films.

Description

[0001] related application [0002] This application claims Chlorine-Free Ink and Coating Compositions and Printing Methods with Improved Adhesion to Untreated Polyolefin Films, filed August 18, 2010, to Huanyu Wei, Youichi Abe, and Helen Rallis (CHLORINE-FREE INK AND COATING COMPOSITIONS&A METHOD FOR PRINTING ON UNTREATED POLYOLEFIN FILMS WrfH IMPROVED ADHESION)" U.S. Provisional Application Serial No. 61 / 374,706. Where permitted, the subject matter of this application is incorporated by reference in its entirety. technical field [0003] The present invention provides chlorine-free ink and coating compositions that exhibit improved adhesion when applied to untreated flexible plastic film substrates. The provided compositions eliminate the need for a separate step of pre-treating the plastic film prior to applying the ink coating composition. Methods of producing printed articles using the ink and coating compositions described herein are provided. Also provided are method...
