Integrity™ TK8 Film

The TK8 film is constructed from laminated layers of PA (polyamide), EVOH (ethylene vinyl alcohol polymer) and ULDPE (ultralow density polyethylene). The outer PA layer provides robust puncture resistance, strength, and excellent thermal stability. The EVOH layer minimizes gas diffusion across the film while maintaining a very good flex crack resistance. The ULDPE layers provide flexibility, integrity and an ultra-clean, ultra-pure, low-extractables product contacting layer. The combination of these layers results in a film that has outstanding optical clarity, is easy to handle, and performs well in a broad range of bioprocess applications. The inner ULDPE layer used in TK8 is blow-extruded in-house by ATMI under cleanroom conditions (0.2μm filtered air), ensuring the cleanest possible product-contacting surface. Lamination is also performed under controlled, ultra-clean conditions. Lastly, TK8 film is converted into ATMI bag products in our ISO Class 5 cleanroom.
