Integrity™ TK8 Film
Process Control, Traceability, Cleanliness
Overview
Outer Layer
PA
Pall Life Sciences is a technology leader in the manufacture
of single-use vessels and consumables for the life science
industry. Integrity TK8 film represents the culmination of
over a decade of experience in ultra-clean polymer film
extrusion and bioprocess vessel manufacture, and delivers
performance to meet or exceed the expectations of the
most demanding users. Integrity TK8 film embodies Pall
Life Sciences “one film” philosophy, giving users access
to a single film capable of serving in the single-use
applications, from storage to mixing and even bioreactor
processes. This approach can yield significant savings in
validation effort, time and cost.

TK8 Film Structure
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 Pall Life Science
under cleanroom conditions (0.2 µm filtered air), ensuring
the cleanest possible product-contacting surface.
Lamination is also performed under controlled, ultraclean conditions. Lastly, TK8 film is converted into Pall
Life Sciences bag products in our ISO Class 5 cleanroom.
Traceability and Compliance
All of the layers in TK8 are made from “medical grade”
materials, meaning that they comply with industry
standards and are subject to strict change controls.
The entire structure of TK8 is totally free of any animal
derived components (ADCF). Pall Life Science has also
created TK8 with dual sourcing and contingency
planning in mind, to ensure security of supply.
• TK8 complies with USP <87>, USP Class VI
(USP <88>) and USP <661>
• TK8 film complies with EP3.2.2.1
• Shelf life is supported by aging validation studies
• Certified ADCF
• Bioburden evaluation available (ISO 11737)
• Particle count data available (USP<788>)
• By performing blow extrusion in-house, Pall Life
Sciences maintains full control and traceability of
the contact film composition, from resin through
to finished bag product
Leachables/Extractables and Chemical Compatibility Data
An extensive dossier of leachables/extractables data is
available upon request. Extractable testing was performed
in CH2Cl2 (8 hours reflux). Leachable tests were performed
at 40 °C over durations up to six months. Leachable
solvents include:
• WFI
• Ethanol (20%)
• Tween (0.1%)
• HCl (pH < 3)
• DMSO (10%)
• NaOH (pH > 11)
(tested at -20 °C)
• Saline (1M NaCl)
Additional studies have demonstrated chemical
compatibility with the following common bioprocess
materials under various, process-typical conditions:
•
•

•
MgSO4.7H2O
Ethanol (55%)

The film is fed directly into Pall Life Sciences ISO Class 5
cleanroom to ensure the highest levels of cleanliness and
bioburden control.
