Highly Efficient Clean Room Blow Molding for Pharmaceutical Bottles and Containers

Highly Efficient Clean Room Blow Molding for Pharmaceutical Bottles and Containers

For industries like pharmaceutical and food processing, contamination can be a huge risk. Therefore, their sensitive products need to be manufactured, handled, and packaged extremely carefully in order to avoid contact with any pollutants such as dust, mold, and microorganisms. As such, isolated spaces known as “cleanrooms” are widely used to eliminate impurities usually generated by humans, processes, facilities, and equipment, and have caused clean room molding to gain popularity. The result? Safe and quality products which comply with the standards and high demands of the industry and application they serve!

How Does Clean Room Molding Work?

Hollow pharmaceutical bottles and containers can be made through extrusion blow molding. During this process, a plastic resin is homogeneously melted and passed through heated barrels until the extruder head and die unit extrudes the hot melted resin into a tube called a parison. After that, a mold closes over the resin tube, sealing its bottom while also forming the neck of the bottle. Compressed air is blown into the parison, expanding it against the sides of the mold cavity. Finally, the bottle is cooled and ejected from the mold, ready to be appropriately trimmed. Clean room molding thus entails the creation of plastic parts in a special room that is optimized to reduce the risk of contamination. This ensures protocol compliance even in the most critical of manufacturing applications.

Who needs a cleanroom?

There are a wide variety of industries and companies that may need a cleanroom. These include those that manufacture containers that are easily affected by contaminants or particles in the air. Some examples of industries that commonly use cleanrooms include the following:
  • Aerospace
  • Military
  • Biotech
  • Medical
  • Pharmaceutical

The Importance of Packaging in the Pharmaceutical Industry

Clean room containers for the pharmaceutical industry are of great importance. As a matter of fact, although the requirements to be met by the packaging of food products are similar, those for pharmaceutical products are more stringent. Generally speaking, medicine bottles should not only protect medicinal products against all forms of spoilage and tampering but also preserve their stability and quality. Packaging quality thus plays a critical role in the quality of such products because it must ensure product protection from light, moisture, oxygen, and temperature variations while also preventing any biological contamination. It is extremely important to control and inspect the manufacturing process including the storage of starting materials and finished products, calibration of instruments or measurement systems, control of labels, sanitation and hygiene, maintenance of buildings and equipment, etc.

Moreover, although it is recommended that the number of employees in a cleanroom is kept at a minimum, those who do perform tasks in this kind of environment should be really careful. As such, in order to reduce skin particles, dirt and other contaminants, employees have to wear a protective suit, a hairnet, a face mask, gloves, sleeve protectors, and boot covers as well as take all the necessary precautions in order to maintain room cleanliness.

Most Common Resin & Machines Used for Blowing Pharmaceutical Bottles and Containers

Highly efficient cleanroom molding requires outstanding machinery and an appropriate plastic resin. In the case of the pharmaceutical industry, HDPE is a plastic resin widely used because this kind of container is not breakable but lightweight, resistant to leakage, and affordable to manufacture. As for machinery, always look for a reliable manufacturer. In Taiwan, Chen Way Machinery has experience providing pharmaceutical bottles blow molding machines to produce plastic packaging for cleanrooms since many years ago.
