Process Recommendations
A process melt temperature above 410°F (210°C) is recommended to ensure adhesion between adherents. More specific suggestions can be made only when equipment, process parameters and conditions of use are known. Contact your Equistar Plexar technical service representative for more information.

Regulatory Status
PX 2246 meets the requirements for the Food and Drug Administration regulation 21CFR 177.1520 (c) (6) for use as the adhesive component in multi-laminate structures, or as the sealant layer in flexible packaging, in contact with food at temperatures not exceeding 49 °C (120 °F). Specific limitations or conditions of use may apply. Plexar tie-layers meet the requirements for the Food and Drug Administration regulation 21CFR 175.105 for adhesives. This regulation describes adhesives which may be safely used as components of articles intended for use in packaging, transporting or holding food in accordance with conditions outlined in that regulation.
