Dow AFFINITY™ GA 1875 Impact Modifier

AFFINITY™ GA 1875 is a low-volatility, high-purity polyolefin plastomer with excellent optical performance and low-temperature sealability. It offers great compatibility with various polymers and complies with U.S. FDA and EU food contact standards, making it ideal for food packaging and composite films.

Features Of Dow AFFINITY™ GA 1875  Impact Modifier

  1. Low volatile matter (<0.15%) and excellent color control (Gardner color <1.00), meeting high-purity and appearance requirements

  2. High clarity and gloss with ultra-low haze, suitable for packaging with strict optical performance demands

  3. Excellent low-temperature sealability with a low heat-seal initiation temperature, improving packaging efficiency and reducing seal shrinkage

  4. Excellent compatibility with polyolefins and various polar materials, usable in monolayer or coextruded films to optimize structure performance

  5. Compliant with U.S. FDA 21 CFR 175.105(c)(5) and EU No 10/2011 food contact standards for safety and regulatory compliance

Typical Applications Of Dow AFFINITY™ GA 1875  Impact Modifier

  1. Food packaging: Used as a heat-seal layer in multi-layer films or as a monolayer, enhancing clarity, seal strength, and contamination resistance for fresh produce and baked goods

  2. Composite flexible packaging: Coextruded with PET, PA, etc., to optimize interlayer adhesion and puncture resistance of composite films

  3. Hygiene products: As an elastic film or heat-seal layer in diapers and sanitary napkins, balancing flexibility and reliable sealing

  4. Hot melt adhesives: Provides stable bond strength for carton sealing and hygiene products over a wide temperature range

  5. Protective films: Adheres to metal and non-metal surfaces with long-lasting tack and scratch resistance
