Affinity™ PL 1880G is a polyolefin plastomer made with Dow’s INSITE™ technology, engineered for high-speed, form-fill-seal packaging. It delivers low seal initiation temperature and excellent hot tack strength, ensuring reliable seals even with package contamination.
Extremely low seal initiation temperature enables fast, secure sealing at low temperatures, boosting packaging line efficiency.
Superior ultimate hot tack strength maintains robust seal integrity even when packaging contents cause contamination.
Excellent puncture and tear resistance provides strong physical protection for contents, reducing damage during transport and storage.
High optical clarity with low haze enhances product visibility, improving shelf appeal for packaged goods.
Excellent compatibility with various polyolefin substrates allows easy co-extrusion, adapting to flexible packaging structures.
High-speed food packaging, such as form-fill-seal bags for snacks and baked goods, meeting the efficiency needs of production lines.
Packaging for oily or contaminated contents, like pet food and frozen ready-meal bags, where seal performance remains unaffected.
Lightweight and durable e-commerce protective bags and cushioning packaging, leveraging puncture resistance to safeguard items.
Flexible packaging for medical and personal care products, including wet wipe bags and single-use hygiene item pouches, ensuring hygiene and seal reliability.
Agricultural functional films, such as greenhouse covers and silage stretch films, utilizing weather resistance and mechanical strength for extended service life.
