2. Pharmaceutical Blister Film and Medical Device Packaging

PA12 film grade plays a critical role in medical and pharmaceutical packaging, prized for low extractables, processability, and stability under sterilization. Pharmaceutical converters depend on this material for deep-draw blister packs or equipment component wraps, where integrity under thermal processing, gamma, or EtO sterilization is crucial. The resin enables tight control over film gauge and ensures low particulate contamination, essential for blister packaging lines and medical device pouches. It allows for transparent, flexible enclosures that can withstand aggressive sterilization without embrittlement.

3. Automotive Fuel Line and Brake Line Inner Layer Films

PA12 film grade functions as a key intermediate in the production of multilayer tubing for automotive fluid handling systems. Processors employ the polymer to form thin, chemical-resistant inner layers in brake and fuel lines, protecting against permeation of fuels, oils, and brake fluids. The rigid yet processable nature of the resin ensures it can be precisely extruded in concentric multi-wall tubular structures, with excellent adhesion to adhesives or polyolefin outer coatings. The product’s low moisture uptake helps maintain dimensional stability and prevents swelling or softening over long-term service.

Industry compliance standards

• SAE J844 (for air brake tubing)
• FMVSS 106 (Brake Hoses)
• ISO 7628 for fuel line tubing requirements
