What are Plastics Industry Cleanrooms?

Plastics industry cleanrooms are used for the research, development, and assembly of plastic components in a controlled environment. Plastics play a valuable role in many industries, from packaging and construction to automotive parts and medical devices. 

Depending on the plastic’s application and the importance of sterility for that use, the processes to manufacture it can require significant regulation. Plastics used in the composition of medical devices, for example, require more extreme care and cleanliness during the manufacturing process than plastic used for less sensitive purposes, such as that used to make furniture.  While some plastics can be sterilized after manufacturing is complete, some plastics or components cannot hold up to heavy sterilization and instead must be developed in a clean environment.

A cleanroom is necessary to control the environment where the plastic is manufactured to ensure product consistency and consumer safety, especially in those applications where the presence of contaminants could present a risk to a patient, employee, or consumer. In a controlled cleanroom space, environmental factors are monitored to limit airborne and surface contamination to an acceptable degree, as outlined by the cleanroom classification.

Plastics Industry Cleanroom Applications

Plastics manufacturing has a place in an abundance of applications, including parts for machines, furniture, automobiles, and aircraft. Plastic is used in food packaging, technology, and even as a building material in construction. In every major manufacturing industry you can find something made or designed using plastic. 

The medical industry is also a major consumer of plastic. From the plastic bags used to keep pharmacological products and surgical equipment clean to the tools and medical devices used by surgeons and staff, doctors and patients alike rely on the sterile production of plastics for health and safety. 

Plastics Manufacuturing Methods

Just as plastic can be used in a variety of ways to meet many demands, there are also many ways to manufacture, or mold, the material to the desired shape, thickness, and purpose. The four main plastic molding methods are:

  • Injection Molding: The most common manufacturing method, plastic is injected into a set mold. The malleable plastic material fills the shape and cools to form the completed component.
  • Extrusion Molding: Melted plastic is pushed through a die to give it shape. This method is commonly used to make seals and pipes.
  • Rotational Molding: To make parts for cars and furniture with rotational molding, plastic powder is put into a mold, heated, and then rotated until the plastic creates an outer layer and leaves a hollow interior. 
  • Blow Molding: A blow mold uses air pressure to shape melted plastic around a parison (pre-shaped hollow plastic piece) that is contained inside. The parison creates a cavity where the plastic has expanded around it. This method is often used to make hollow containers and bottles.

All of these manufacturing processes require careful control to make sure the plastic is heated, cooled, and molded correctly without defects or contamination that could cause it to fail. Changes in temperature, humidity, pressure, static, or other factors could have serious consequences in plastics manufacturing — especially if the plastic products have sensitive or complex purposes. Fortunately, the controlled environment of a cleanroom can limit the ability of these forces to affect manufacturing processes. 

Cleanrooms can provide control over humidity, particles, contamination, pressure, and temperature to ensure consistency and cleanliness in your products and testing. In plastics manufacturing, cleanrooms are regulated by classification standards that set the allowed number of particles at different sizes, and also govern necessary air changes to make sure the space stays clean.

plastics industry Cleanroom Classifications

Plastics industry cleanrooms are regulated by cleanroom classifications set by the International Standards Organization, or ISO. The ISO classifications designate the allowed contaminants in a cleanroom environment, filtered by particle size and number. 

ISO 14644-1 is divided into 9 classes, where Class 9 is equivalent to room air and Class 1 is the cleanest possible environment. Most plastics manufacturing cleanrooms fall under the requirements of ISO Classes 7 or 8, meaning a maximum number of particles of .05μ or greater in the air ranging from 352,000 to 3,520,000. Some plastics manufacturing applications that are especially sensitive to contamination or involve more complex assembly may require a more stringent cleanroom classification, such as ISO Class 5 or 6.

As the classification decreases, a cleaner space is required. Plastics industry cleanrooms that are required to have a high level of control must continually change the air to remove contaminants and push clean air into the space. They require the implementation of an efficient HVAC and HEPA filtration system to ensure the air is changed consistently and effectively and maintained at a stable temperature and humidity level.

Other industry-specific standards (such as ISO 9001ISO/TS 16949, or ASTM E2352) may be in place to ensure your cleanroom is properly equipped to manage the unique threats to productivity and safety it may face. 

With complete control over the manufacturing space managed by your cleanroom — including filtration, temperature, humidity, and static — you’ll be able to focus on your work. Your cleanroom will also be fully customized to contain all the equipment, fixtures, and tools you’ll need to be successful. Additionally, if your project needs change, Angstrom Technology’s modular cleanrooms have the advantage of being easily modified or reconfigured. They can even adjust to a new, more stringent standard if you need to upgrade at any time — and not slip in quality or efficiency.

plastics Industry Cleanroom Design

Plastics industry cleanrooms are designed to establish as much control over the manufacturing process as possible, particularly to maintain a favorable environment. Without control over the environment, contaminated products may not be effective or could fail and have severe consequences for consumer health and safety. While cleanrooms can’t replace the need for proper sterilization of plastic products, they can ensure proper control during the manufacturing process — which is especially important for products that can’t withstand sterilization procedures or have sensitive uses.


Plastics industry cleanrooms must be able to maintain a sterile environment while allowing normal operating procedures to occur with cleanliness and efficiency. They should have adequate room for personnel to move, as well as cranes, carts, and other transport equipment. All cleanrooms need to design connections for water, electrical, and air handling systems, as well as create space for storage for cleaning supplies and gowning areas. Plastics manufacturing cleanrooms must also accommodate large equipment, such as plastic injection molding machines which can range in size from 50 to 1,000 tons.


With all of the vital features included, a cleanroom should only be as expansive as necessary to allow for efficient energy usage and to limit operational costs. Angstrom Technology designs, builds, and installs high quality cleanrooms to meet your project specifications, comply with all cleanroom classifications, and operate efficiently. We will work with you and your facility’s budget to set up your space with everything you need to get your cleanroom up and running as soon as possible and make your work a success.

plastics manufacturing air filtration 

A vital part of any cleanroom design involves its airflow pattern. The ideal airflow pattern is powerful, thorough, and consistent, to reduce contamination both in the air and on surfaces within the space. Every change of the air will remove particles evenly and effectively — the first time and every time. Having dedicated fan filter units and a custom airflow pattern that work with your cleanroom space will ensure that happens.

Your cleanroom HVAC regulates temperature and humidity levels within the manufacturing environment, not only to keep your employees comfortable, but to keep machines functioning at optimal levels and protect sensitive products and processes within the cleanroom. Fluctuations in temperature and humidity can be detrimental to productivity and your bottom line, so a reliable HVAC system is a must in any cleanroom design.

plastics industry cleanroom pressurization

Positive pressure cleanrooms are used in the plastics industry to protect the products and processes inside from contamination outside of the cleanroom. To achieve positive pressure, more air is pumped into the cleanroom than is filtered out. A positive pressure environment can effectively reduce contamination risks and improve cleanliness.
