Key Features
Nylon 6 Film (polyamide 6, PA6) is a semi-crystalline engineering polymer film combining good tensile strength, abrasion resistance, and one of the best oxygen barrier performances available in a commodity polymer film:
Outstanding Oxygen Barrier Performance
One of the best oxygen barrier performances available in a commodity polymer film, making Nylon 6 the preferred structural barrier layer in food contact packaging requiring both mechanical integrity and gas barrier function.
Good Tensile Strength and Stiffness
Tensile strength of 55–70 MPa and tensile modulus of 2.4–3.0 GPa qualify Nylon 6 film as the structural layer in cook-in food packaging laminates and vacuum packaging applications where the film must withstand processing and handling stresses.
Inherent Flame Resistance and Elevated Service Temperature
Limiting oxygen index of 24–25% provides a degree of inherent flame resistance, and service temperature reaches approximately 120 °C in the dry condition, qualifying Nylon 6 for packaging subject to elevated temperatures including cook-in processes.
Significant Moisture Sensitivity
Equilibrium water absorption of 8–10% softens and plasticises the film, reducing modulus and dimensional stability. This moisture sensitivity is the primary design consideration for all Nylon 6 film applications and is managed by lamination with moisture-barrier layers in multilayer structures.
Good Abrasion Resistance
Surface abrasion resistance qualifies Nylon 6 film for packaging applications subject to mechanical abrasion during processing, handling, and transit, where lower-abrasion-resistance films would develop surface damage.
Industrial Applications
Nylon 6 Film is used across food packaging, pharmaceutical packaging, and industrial flexible packaging wherever oxygen barrier performance, structural integrity under processing, and compatibility with cook-in and vacuum packaging processes determine material selection:
- ✦ Cook-In Food Packaging Laminates
- The dominant structural barrier layer in cook-in food packaging laminates, where the combination of oxygen barrier performance, tensile strength, and 120 °C service temperature qualification supports use in the most demanding flexible food packaging applications.
- ✦ Vacuum Packaging for Processed Meats and Cheese
- Applied as the oxygen barrier layer in vacuum packaging for processed meats and cheese, where the film’s outstanding oxygen barrier performance extends product shelf life by suppressing aerobic spoilage.
- ✦ Pharmaceutical Blister Pack Backing Layers
- Used as pharmaceutical blister pack backing layers where oxygen barrier performance, tensile strength, and compatibility with heat-seal processes protect oxygen-sensitive drug products.
- ✦ Gas Barrier Film for Industrial Flexible Packaging
- Applied as the gas barrier layer in industrial flexible packaging for oxygen-sensitive products where the combination of structural integrity and oxygen barrier performance qualifies Nylon 6 over lower-barrier polyolefin alternatives.
- ✦ Membrane Transport, Friction, and Crystallization Research
- Used for membrane transport and diffusion studies, friction and wear characterization of polyamide surfaces, water absorption and moisture diffusion kinetics investigations, and as a model semi-crystalline hydrogen-bonded polymer for crystallization and mechanical property studies.
