BOARD MEETING

DATE: January 12, 1996

AGENDA NO. 23

REPORT: Feasibility of Using Rule 1130 - Graphic Arts Compliant Inks in the Flexographic Printing of Polyethylene and Polypropylene Bags

SYNOPSIS: On September 8, 1995, as part of the public hearing on proposed amended Rule 1130 - Graphic Arts, the Board directed staff to conduct a technology assessment on the flexographic printing of polyethylene and polypropylene bags and report our findings at the January 12, 1996, Board meeting. This report provides staff findings on the feasibility of using compliant inks in the flexographic printing of polyethylene and polypropylene bags for tortillas, produce (carrots), frozen foods, pharmaceutical products, and manure. It also provides staff recommendations for further rulemaking.

In preparing this report, staff visited 21 facilities printing the polyethylene and polypropylene bags in question. Three of them are located in California but outside of the AQMD. In addition, staff spoke with several printers located outside of the AQMD to determine what ink systems and equipment they were using, and to seven ink manufacturers to obtain information regarding the compliant inks that are available for use.

This report concludes that both ink and add-on control technologies exist today that allow flexographic printers to comply with the 300 gram per liter VOC limit in Rule 1130 for printing the polyethylene and polypropylene bags in question . Compliant ink technology is in use within and outside of the AQMD while add-on control technology is currently only in use outside of the AQMD. In addition, this report identifies VOC RECLAIM, once adopted, as a viable option for flexographic printers to achieve compliance with AQMD requirements. As a result, no change is proposed for the existing VOC limit of 300 grams per liter.

Staff will continue to work with this industry to assist printers in their efforts to achieve compliance.
