A. General Description of the PSD Film and Articles
All of the layers in PSD are made from “medical grade” materials, meaning that they comply with
industry standards and are subject to strict change controls. The entire structure of PSD is totally free of
any animal derived components (ADCF). Pall has also created PSD with dual sourcing and contingency
planning in mind, to ensure security of supply. The structure of the lm is as follows:
Contact layer 45 µm LDPE + permanent antistatic
Inner layer 150 µm LDPE/ULDPE
Outer layer 45 µm LDPE + permanent antistatic
This composition allows permanent antistatic properties without any migration of antistatic additive in the
content of the bag.

B6.5. Functional Tests on Powder Handling Bag
B6.5.1. Functional Weight Test
Test method: Gamma irradiated (min 50 kGy) bags are lled with different
weights. The test has been done with 3 samples per bag for gamma
irradiated bags. A lled bag hangs on a round hook for 7 days by
its handle.
Weight Test Gamma (min 50 kGy)
Volume Connector Weight # of Samples
5 L 2 in. 5 kg 3
15 L 4 in. 15 kg 3
30 L 4 in. 30 kg 3
40 L 6 in. 40 kg 3
50 L 6 in. 50 kg 3
100 L 6 in. 100 kg 3
Result: The irradiated bags can hold max 25 kg per handle. During the
holding time there has been no bending of the handle, no peel or no
visual seal elongation.
B6.5.2 Powder Transfer Efciency
Test method: The empty bags with tment and the gasket, clamp and
sanitary clamps are weighed. The bags are lled with powder (3 kg in
15 L bags and 6 kg in 30 L bags). The bag is rst closed with a pinch
and then with a gasket, cap and sanitary clamp. The bag is shaken so
that the powder reaches all sides of the bag. The gasket, clamp and
sanitary clamp are removed. The pinch is removed and the bag is
emptied in another bag. The empty bag with tment and the closing
system is weighed. The amount of powder that remained in the rst
bag and on the closing system is calculated.
The test was performed with sucrose, salt, lactose, diatomaceous earth
(Celite) and medium on 15 L – 4 inch bags. The test with salt has also
been replicated on the 30 L bag.
The % powder transfer for all types of powder is very high and > 99.9%.
The residues are mainly located at the 60° seal, followed by the connector
seal and the double bottom seal. On the lm itself, only a residue is left for
the very thin powders like lactose and diatomaceous earth.
The % transfer data on the gamma irradiated bag are in line with the data
measured on the non-gamma bags. The % transfer of all powders is
again very high and above 99.9%.

B6.5.3 Functional Drop Test
A bag lled with NaCl is dropped from a hanging and from a vertical lying
position and then checked if it is intact as described in ASTM 5276-2009
and 49 CFR (Code of Federal regulations) Chapter 1 part 178.
Before gamma irradiation
The drop test was carried out on 4 different volumes of bags (5 L, 15 L,
30 L and 50 L, respectively lled with 5 kg, 15 kg, 30 kg and 50 kg salt).
Two types of tests were performed: the at drop test and the hanging
drop test.

50 L Bag Bag 1 Bag 2 Bag 3
1.2 m at drop PASS PASS PASS
1.5 m at drop PASS PASS PASS
All bags passed the 1.2 m at drop test up to 50 L bag (lled with 50 kg
salt). This test was repeated on 3 different bags. At least one of these 3
bags was tested again at 1.5 m. All bags passed again the test at 1.5 m
at drop.
The most critical test was the hanging drop test. Only the 5 L bag
passed this test. For the 15 L and 30 L bags, this test failed for 33%.
The failure was due to the 60° seal break. The breakage occurs at the
area at which the connector touches the 60° seal after the drop.
Based on these results, it will be recommended to customers to
transport the lled, higher weight bags in a at position.
After gamma irradiation (min 50 kGy)
The drop tests on gamma irradiated bags were only performed on the
highest weight bags: 30 L and 50 L (respectively lled with 30 kg and
50 kg salt).

The at drop test was repeated for each volume on 3 bags. If the test at
1.2 m was positive, the same bag was tested at 1.5 m. All bags up to
50 L (lled with 50 kg) passed the at drop test at 1.2 m and 1.5 m. So
data are in line with the drop test results before gamma.
The hanging drop test was only performed on the 30 L irradiated bag.
The 30 L bag passed the test for 100%. This is not the case for the 30 L
bag before gamma.
The gamma irradiated 60° seals seem to be superior the to 60° seals of
the non-gamma CPTB in terms of hanging drop test.
B6.5.4. Conclusion
Powder transfer bags may be lifted and supported by their integral
handle alone, provided they contain not more than 15 kg of material. If
loads above 15 kg are anticipated, Pall recommends using an external
support device such as a tray, tank, support rod or overbag to avoid the
risk of the handle becoming distorted. Loads above 50 kg are not allowed.
As with all single-use containers, care must be taken at all times not to
allow any hard/sharp objects to puncture the bags while they are being
used or transported.
C. Aging Test Study - Accelerated Shelf Life Study

An accelerated study has been performed in order to prove that lm and product has minimum
a shelf life of 3 years.
The study was conducted on irradiated material as a worse case, to cover both irradiated and
