ABSTRACT
This thesis describes the inspection process and requirement for Blow Fill Seal
Automated for the Pharmaceutical Industry. This thesis describes the cleaning process
which consists Clean In Place (CIP) and Sterilization In Place (SIP). The processes are
Clean In Place (CIP) and Sterilization In Place (SIP). Both the cleaning process is to flush
the all particle in Piping, inlet and of the machine. For the inspection process it is very
critical for the pharmaceutical products this to be inspected effective and in short time
before being delivered. Eye inspection by human is prone error. Therefore this thesis
propose the use of machine vision to carry out the inspection tasks. The digital camera is
use to capture image of product to be analyze using vision system. Automated inspection
would reduce human error in executing inspection task.

CHAPTER 1 INTRODUCTION
1.0 Introduction
In the modern medical treatment, pharmaceutical solutions were the packed usually
in plastic bottle. It very safe compares with former time them usually using glass as a
packaging container or the empty plastic by using conventional filing process. Such
process required extensive precaution for manufacturing pharmaceutical sterile
product due to the difference local positioning the individual manufacturing steps,
which usually in relatively high production costs.
In the current technology, the Blow Fill Seal Process (BFS) is characterized
by the fact that the sterile plastic container production as well as the sterile filling and
closing of the container of the performed at the same place.
This technology was developed by the Germany Company called Rommelag
group since 1960s and it was already at the end of the 1960s. On 1970s when the
bottle pack Blow Fill Seal (BFS) machine were applied for pharmaceutical solution.
Start from early day, the solution used were mostly large volume products like post-
sterilized influence. However today, the Blow Fill Seal machine can produce many
type of volume, such small volume unit-dose for injection, contact lens cleaning
solution, food industry, eye drop solution and other solution.
The plastic materials for manufacturing the container offer a considerable
higher flexibility in the design of packaging compare to the glass packaging. When
using plastic as a bottle pack material, every thing is possible to containers with
2
round, oval, angular cross section or bellow bottle design. The flexibility also allows
mould closure design which can meet the requirement of a special product
application.
For the course time, diversification of blow fill seal machine program took
place in order to cover difference capacity needs. At the same time, the individual
components were developed further in the order to meet the increasing requirement
of the clients and authorities of the pharmaceutical sector.
The Blow Fill Seal machines normally operate after water preparation,
product preparation and sterile filtration. The filling product is fed in sterile condition
to the bottle pack blow fill seal machine. The plastic granulate is transported from the
resin material storage to the blow fill seal machine. This processed there to plastic
packaging, filled with the filling product and sealed immediately.
The essential components of the blow fill seal machines themselves are a
resin-extrusion equipment and container molding system with the integrated dosing
process as well as separated cabinet modules where motors, pump, ventilator, valves,
and electrical installation to control the machine.
The blow fill seal process start with the forming of the plastic container.
Usually they use the low, medium and high density polyethylene as well as melted,
homogenized and extruded as plasticized parisons. In the blow process, the extruder
parisons are molded as container in the mold. After that, they are filled immediately
at the same position by dosing needles with the requested filling quantity. After
completion of dosing, the filling mandrels rise vertically to their upper rest position
and special closing tools weld the container hermetically, where the requested
closure is welded by vacuum. After that the entire mold opens and the container is
discharged the cycle begins again. The duration time to complete this process is
depending on the container design and the filling quantity between 10sec until 18sec.

In the pharmaceutical industry, the Blow Fill Seal product called Intravenous
Solution (IV Drips). The IV Drips function is to supply of nutrition with or without
medicine direct into the blood stream of the patient. This solution must be clean from
any contamination, sterile from any microorganism and non-pyrogenic substance and
temper bottle. The nutrition content can be one or a mixture of carbohydrate, mineral
salts, protein, fats and vitamins which are needed daily for patient’s survival. The
nutrition in IV drips is in the simplest form and can be absorbed by the human body
direct without with other process. This solution administered intravenously cannot be
removed from the patient by any mechanical or other means. In medical field, IV
drips is very importance because patients need nutrition daily to survive, recover and
recuperate their body. They also cannot and drink by usual means. They must used
this IV Drips to produce energy to survive. The IV Drips is a vehicle for antibiotic
and medicine treatment to treat the patient ailment.
The manufacturer must have relevant license certificate from National
Pharmaceutical Control Biro (NPCB) from Malaysia Ministry of Health. The issued
must issue by Malaysia Ministry of Health Director. Their certificate must renew for
annually. Manufacturer must conform to the requirement for good practice in the
manufacture and quality control as recommended by World Health Organization
(WHO) and the Malaysian guideline on Good Manufacturing Practice. If any
manufacturer not fulfills the Malaysian guideline or their product fails such as not
sterile, pyrogenic, wrong labeling, wrong concentration and Good Manufacturing
Practice by NPCB, the line process can be close.

CHAPTER 2 LITERATURE REVIEW
2.1 Introduction
When we look at the plastic bottle, can we think how to produce that bottle?
What the material they used? For this project we want to describe how to make it?,
what the machine they used? What the automation element at the machine?.
Basically, the plastic bottle produce by lower density plastic (LDPE). The main
industry used this bottle is the pharmaceutical industry and food industry.
For this thesis we want to describe effectiveness and cleanliness of blow fill
seal (BFS) technology in pharmaceutical industry. In pharmaceutical industry the
cleanliness is very important to use it because it must sterile process to avoid any
contaminations and sterile from microorganisms in the product.
The automation element also we discuss in this thesis. We can research about
the automation to support the product produce. This thesis also can discuss about the
down time for machining process.

Figure For Step Process Description
Step 1
Extrusion
• The transparent polyethylene containers of medium density
allow a post a post-sterilization of up to approximately
1100C.
• In the extrusion system, the resin is heated up to 1700C-
2300C, whereas pressure of up to 350 bar exist. The
container result in the sterility of the resin which is
discharged as parisons. In various challenge tests in which
bacterial inoculated resin contamination with the
endotoxines were used, no growth of germs was discovered
after evaluation and no endotoxines was proven to be in the
plastic granulate are surrounded by the plastic melt and
therefore cannot migrate from the packing into the product
Step 2
Molding
• When the parison is taken over by the mold, it is separated
by an incandescent cutting knife below the extrusion die and
within a second the mold with the parison move to the filling
position. Sterile air with which the parison was kept under
pressure escape at the upper opening of the parison and
avoids the surrounding air entering into the parison and the
sterility within the parison is kept.
• The mold has reached the blowing/filling position, the
combined blowing/filling mandrel moves from the upper rest
position into the open parison. The parison is then blown up
with sterile air and is pressed against the mold wall.
The machine preparation, the blowing and filling mandrel
are sterilized. Except during the blowing and filling. The
combined blowing and filling mandrel are the upper rest
position in a special sterile chamber where they are flushed.
