POLYAMIDE AND BARRIER POLYMERS FOR CASING
Synthetic sausage casings crafted from polyamide are frequently encountered. These casings are produced using an extrusion method, wherein nylon is melted, blown, in three bubbles, obtaining a tubular form film. Subsequently, they are cooled and cut precisely to the desired lengths. This type of packaging is used for a wide variety of sausages and processed meat products.
NUREL presents a dedicated selection of PA6 meticulously tailored for casing purposes, in addition to Enoxite Smoke, a novel line of special barrier polymers, designed to produce synthetic casing for smoked sausages with different levels of smoke penetration.
KEY REQUIREMENTS FOR CASING & SMOKED CASING APPLICATIONS
High-Performance Polyamides for casing applications
Polyamide is a key material in the production of synthetic casings for sausages and processed meats, thanks to its exceptional strength, barrier performance, and versatility.
PROMYDE® PA grades offer consistent shape retention, excellent mechanical resistance, and a reliable barrier against external contaminants, while enabling controlled moisture and gas transmission.
Aditionally, PROMYDE® PA performs exceptionally well in Three-Bubble extrusion processes.
These qualities make it a trusted choice across the meat processing industry.

PROMYDE® BF40 (STANDARD PA6)
PROMYDE® BF36SC
PROMYDE® BF933
PROMYDE® BF642
SUSTAINABLE APPROACH:
All materials are available in a biodegradable version. They can biodegrade in aerobic (ISO 17556) and anaerobic (ASTM D5511) environments.
NEW SOLUTIONS FOR smoked food casings
When it comes to products that undergo smoking processes, ensuring high quality and extended shelf life is essential—especially for processed meats and sausages.
For these applications, the casing film must offer a controlled permeability, allowing the passage of smoke components and water vapor.
This enables aroma and color infusion, improves product appearance and flavor, and supports preservation without compromising freshness.

ENOXITE® Smoke is a technical polymer designed for smoked food casings, offering an excellet smoke permeability. To achieve the necessary smoke penetration in the production of smoked meat, a mixture of PA with 20-30% of ENOXITE Smoke S20 is recommended.
It is also possible to combine these products with copolyamides.*
