Dow AFFINITY™ PT 1450 G1 Impact Modifier

Affinity™ PT 1450G1 is a polyolefin plastomer produced via Dow’s INSITE™ technology, designed for monolayer and coextrusion coating applications. It provides low-temperature seal initiation, strong ultimate seal strength, excellent adhesion to OPP, and superior taste and odor performance, complying with U.S. FDA regulations.

Features Of Dow AFFINITY™ PT 1450 G1 Impact Modifier

  1. Low-temperature seal initiation enables fast, reliable sealing at reduced temperatures, ideal for high-speed packaging lines.

  2. Superior ultimate seal strength ensures robust, long-lasting seals that resist package failure during transport and storage.

  3. Excellent adhesion to oriented polypropylene (OPP) substrates, creating durable bonds for multi-layer packaging structures.

  4. Impressive taste and odor performance, preserving the sensory quality of food and sensitive packaged contents.

  5. Formulated without antiblock, slip, or processing aid additives, ensuring purity and compatibility with demanding applications.

Typical Applications Of Dow AFFINITY™ PT 1450 G1 Impact Modifier

  1. Monolayer and coextrusion coating for flexible food packaging, including snack bags, bakery wraps, and confectionery pouches.

  2. Sealant layer for oriented polypropylene (OPP) laminates, used in high-speed form-fill-seal packaging systems.

  3. Cost-effective alternative to acid copolymers as a sealant for foil or PET laminates in food and personal care packaging.

  4. Packaging for sensitive products such as coffee, tea, and pet food, where taste and odor protection are critical.

  5. High-performance coating for paper and board substrates, providing moisture resistance and heat-seal functionality.
