POLYAMIDE AND BARRIER POLYMERS FOR CASING<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Synthetic sausage casings<\/strong> crafted from polyamide are frequently encountered. These casings are produced using a triple-bubble 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<\/strong>.<\/p>

NUREL presents a dedicated selection of PA6<\/strong> and copolyamides meticulously tailored for casing purposes, in addition to Enoxite Smoke<\/a>, a novel line of polymers designed to increase water vapour permeability<\/strong>, in order to produce synthetic casing for smoked sausages with different levels of smoke penetration.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Polyamide is a key material in the production of synthetic casings <\/b>for sausages <\/b>and processed meats<\/b>, thanks to its exceptional strength<\/b>, barrier performance<\/b>, and versatility<\/b>.<\/p>

PROMYDE\u00ae PA grades offer consistent shape retention<\/b>, excellent mechanical resistance<\/b>, and a reliable barrier <\/b>against external contaminants, while enabling controlled moisture <\/b>and gas transmission<\/b>.<\/p>

Aditionally, PROMYDE\u00ae PA performs exceptionally well <\/b>in Three-Bubble<\/b> extrusion processes<\/a>.<\/p>

These qualities make it a trusted choice across the meat processing industry.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

When it comes to products that undergo smoking processes<\/b>, ensuring high quality<\/b> and extended shelf life <\/b>is essential\u2014especially for processed meats <\/b>and sausages<\/b>.<\/p>

For these applications, the casing film must offer <\/b>a controlled permeability<\/b>, allowing the passage <\/b>of smoke components <\/b>and water vapor<\/b>.<\/p>

This enables aroma and color infusion, improves product appearance and flavor, and supports preservation without compromising freshness<\/b>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
