Thank you for kindly re-posting your question.
Here's what I found for you:
Comparisons/Evaluations Of Non-PVC Bag Machines in
Pharmaceutical/Other Medical Applications:
I searched and searched, but couldn't find any such evaluations
limited only to pharmaceutical applications. I could only find pro &
con comparisons regarding non-PVC vs. PVC, and within more generalized
Also, I could only find comparisons by attributes -- not drawbacks.
Overviews/Comparisons Of Various Non-PVC Bags Machines For Pharmacy:
PTI, Packing Technologies and Inspection, LLC, has a list of bags
machines, and bag testers, and their most notable assets:
Best of all, when you click on the brand/model name at the extreme
left, it will bring up a close-up page on that product that lists that
model's best advantage(s).
For instance, click on the product name "Seal Scan" at left, and it
brings up this page:
"Unique Attributes: The ABUS 550 uses special ultrasonic transmitters
and receivers, this gives an indication of heat seal integrity,
precisely identifying the size and location of a defect."
Clicking on the THIMONNIER I.V. Bag Making & Filling Equipment" next
to "THIMONNIER 1800", at extreme left, brings up:
"ADVANTAGES: Designed to run w/ ea. of the existing referenced
polyolefins-based materials; Bag formats produced from "one roll
width" only: no need to change roll when changing bag format; Bags
fitted w/ tubes of different length (30 - 60mm)or diameter."
"ADVANTAGES (additional): Constant edge control/film centering using
ultra-sonic sensing techn. (single/double wound); Multi-step sealing
techn. w/ automatic re-centering of tubes under sealing jaws;
Stainless steel construction; Driven by real time industrial PLC w/
Here's a comparison, " PRODUCT UPDATE: FORM-FILL-SEAL EQUIPMENT Offers
Versatility," from the Sept. 2000 issue of Pharmaceutical and Medical
Packaging News Magazine:
The above article presents a solid roundup of detailed overview of
various non-PVC machines. Brands include:
Enflex, made by Key International Inc.
The Sureflow Model 8000 made by Mahaffy & Harder Engineering Co.
The MS235, made by Marchesini Packaging.
The V12BT6S made by Circle Packaging Machinery Inc.
The automatic open-fill-seal system, made by About Packaging Robotics Inc.
The Model 40, from AmeriPak.
PLC-controlled vertical form-fill-seal machines, from Packaging Aids Corp.
The R230 and R530 models, made by Multivac.
The Bagmaster series and the C-series baggers, made by Batching Systems Inc.
All of the above manufacturers are hyperlinked, so you can easily make
your way to each company's Web site for more details and to see more
European Medical Device Manufacturer Magazine featured this roundup of
bag machines (including Thimonnier):
(Just as with the Pharmaceutical and Medical Packaging News Magazine's
piece, you're not going to see "cons," per se, but you will get a solid
comparison of features among various models and brands.)
Pharmaceutical Solutions & Materials Discussion Groups:
At Medical Packaging News Magazine's site you can also easily link to,
then register (for free), at Medical Device Link's discussion forum:
I couldn't find a discussion of non-pvc bags machines there, but you
can certainly start such a discussion and ask fellow forum members to
post their experiences with, and opinions on, various brands of
Pharmaceutical Online also has a discussion forum:
where you can also post and seek feedback and comparisons. I would
suggest you try posting in the "All Clinical Materials" forum.
Be aware that at both groups you'll run into a lot of annoying ads
from manufacturers' sales reps. You'll have to weed your way through
those, but it may be worthwhile to contact some of those reps to ask
if they have any comparison studies they can send you. (IF they do,
they're sure to be studies that put their products in a good light
(!), but you may still be able to glean some solid comparative data.)
HighBeam Research (formerly eLibrary):
Offers a free trial which allows you to see abstracts. You must choose
full membership ($19.95 a month) to read the article online. However,
the free abstract will allow you to see the publication and volume
number from the article's publication, so you might be able to find
that magazine at a library, for free.
I searched HighBeam using the term "non-pvc AND bags," but still
failed to come up with a model-by-model comparison.
Using the search term "non-pvc" will yield some potentially helpful
information though, such as this 2000 press release:
"Pactiv Corporation . . . a specialty packaging company, today
announced that it has received a Medical Design Excellence Award
(MDEA) for its Propyflex(R) PVC-free bags."
General Background On Non-PVC Bags:
The FDA's 1999 "Workshop on Plasticizers: Scientific Issues in Blood
Collection, Storage and Transfusion (Plasticizers in Blood Bags):
includes a discussion of Baxter's products. However, this presentation
pertains to blood collection.
