Aegis® H85NP

Widely used to manufacture vacuum bags, casings and pouches for packaging, Aegis® resins deliver outstanding performance that is valued by film producers and their customers. The strength and barrier qualities of Aegis® resins help maintain everything from the aroma of fine ground coffees to the freshness of high-value steaks, and the integrity of life-saving medical devices. These resins offer outstanding performance that provides improved protection and extended shelf life for food and other products in consumer and industrial markets. They also help maintain the aroma and taste of foods. Good flexibility and performance over a wide range of temperatures makes them a material of choice for many applications.

Performance

Aegis® resins are specifically engineered for packaging applications, and are available in low, medium and high viscosity grades with a variety of additive options. Excellent processability during extrusion and consistent quality ensures optimal process performance and end product quality. They are suitable for fabricating film through nonoriented and biaxially-oriented (BOPA) cast film extrusion, as well as multilayer blown film extrusion. These films can be coextruded or laminated with other materials or films, such as polyethylene or ethylene vinyl alcohol (EVOH), to achieve the required optimal packaging properties.

Key Nylon Film Benefits

Material Handling

Aegis® H85NP homopolymer is supplied in sealed containers and drying prior to processing is not required. However, high moisture is the primary cause of processing problems. If drying becomes necessary, a dehumidifying or desiccant dryer operating at 80°C (176°F) is recommended. Drying time is dependent on moisture level.

From flexible packaging for food and consumer products to vacuum bagging for industrial goods, Aegis® packaging grade resins are widely used in a variety of applications, including:

• Processed meats and cheeses
• Coffee, nuts and spices
• Snacks and frozen foods
• Pet foods
• Detergent bags
• Composite fabrications
• Medical devices
• Novelty balloons

AdvanSix has more than 50 years of experience in the development and production of packaging resin that is safe and reliable for consumers and businesses. Aegis® packaging resins are manufactured to meet the stringent standards required of materials involved in the processing, handling and packaging of food. They meet all applicable U.S. Food and Drug Administration (FDA) and European Union (EU) food grade regulations, as outlined in FDA 21 CFR 177.1500 and Regulation (EU) No. 10/2011.

Melt Viscosity vs. Temperature

Melt Temperature: 220°C (428°F)
Melt Temperature Range: 232°C (450°F) to 271°C (520°F)
Two key factors affect the melt viscosity (stiffness or fluidity of the melt):

• The molecular weight (Mw) of the resin: Higher Mw resins will have a higher melt viscosity than lower Mw resins.
• Temperature of the melt for any given Mw resin: Higher process temperatures will provide a more fluid melt viscosity than lower process temperatures.
