, you must determine if a clean room is necessary. Cleanrooms are designed to maintain extremely low levels of particulates. These particulates can cause damage to sensitive items such computer components, Semiconductor fabrications, solar panels, batteries, and other sensitive products. They can come in many sizes and can even encompass entire manufacturing facilities depending upon the products being manufactured there. Contaminants, such as dust, and other airborne organisms can cause irreparable damage to these products, and cleanrooms are designed to defend against such contaminants. They are built specifically to manage and maintain a specific level of particulates that would not harm these products and typically have a cleanliness level quantified by the number of particles per cubic meter.

Second, once the classification is identified this will determine your layout and design. For example, ISO 8 does not require you to enter through an airlock, while ISO 6 does.

Cleanrooms maintain particulate-free air using an HVAC system which is at the core of every clean room. The system uses either HEPA or ULPA filters using an air flow principle known as the Laminar principle. The principle uses air which is forced in a single direction in a constant stream. The stream forces the air into filters in the room so they may be recirculated over and over again removing the particulates from the air., for the clean rooms to maintain its ISO level the air in the room will need to be swapped out over and over every hour throughout the day How many times will depend on the ISO level you wish to maintain. This is known as the ACH (Air changes per hour), once the ACH is established we can figure out air flow required within the clean room space. There are many factors to consider here but for our purposes we will ignore some of these for the moment, so we end up with a more simplified formula:For Example: Your space is 10Wx10Lx8H. Room volume is Length x Width x Height or 800 Cubic Feet. You want to maintain an ISO Level 6. You can plug in the ACH of 150. Your final formula is:The CFM will help determine the number of filters would be required based on their capacity giving you the basic framework to determining what your space will look like.These things will need to be kept in mind while developing the layout of your space.

The electronic industry, medical facilities, and pharmaceutical sectors use cleanroom bags to store and transport sensitive products and protect them from contamination. Cleanroom bags are designed to keep your products free of contaminants and airborne particles, helping you maintain their quality and function.
Choosing the proper cleanroom packaging is vital since it directly impacts your product&#;s success or failure. Remember that bags for clean rooms should comply with standards and meet strict cleanliness and quality guidelines. Paying attention to the following four factors when shopping for cleanroom packaging is quintessential.
1. Cleanroom Packaging Types
Cleanroom bags are available in various formats for different industries and their specific needs. Based on your unique cleanroom purposes, you may choose between the following cleanroom bag categories:
LDPE Poly Bags
Low-density polyethylene bags, also known as LDPE poly bags, are ideal for general cleanroom purposes. They are made of versatile materials with exceptional moisture-barrier properties, tensile strength, and enhanced clarity. Clear poly bags are usually made from barefoot resin and are translucent. Still, it is possible to modify their formulation to improve transparency.
Thanks to their flexibility, LDPE bags come in handy for various applications. Supermarkets, the electronic industry, pharmaceutical companies, medical and biotech labs, or during gamma-irradiation processes commonly use them.
While LDPE poly bags have many features and advantages but are not temperature-resistant; therefore, they should not be used for freezer, microwave, or steam sterilization applications.
HDPE Bags
High-density polyethylene (HDPE) bags are designed to be puncture- and temperature-resistant. They also have an excellent moisture barrier and incredible strength, making them suitable for industrial applications.
Unlike previously-mentioned LDPE packaging supplies, HDPE bags can withstand extreme temperatures. Namely, their softening point ranges from 210 to 220°F, while -180°F is their embrittlement temperature.
Nylon Cleanroom Packaging
Nylon cleanroom bags deliver a strong barrier to oxygen and moisture transmission. Other features include transparency, puncture- and scuff resistance, and excellent resistance to extreme temperatures. Different industries opt for nylon cleanroom bags for their ability to reduce tears and scuffing, commonly caused by friction rubbing.
The nylon material stays stable during and after the gamma irradiation process and performs quite well in vacuum applications. You can go for nylon cleanroom bags with Easy Tear formulation to open the packaging more seamlessly and reduce the risk of potential product damage.
Moisture-Barrier Cleanroom Films
Moisture-barrier films ensure your product is entirely safe from moisture vapor and oxygen transmission. In addition, this film is characterized by its strength and distinctive foil appearance.
You can use moisture-barrier films to store and transport sensitive electronics, medical devices, or items requiring a space free of contaminants, microorganisms, and airborne particles.
Cleanroom Poly Tubing
Cleanroom Poly Tubing is typically used in automotive and medical industries as it allows you to put an item lengthwise into the tubing and heat seal it effortlessly. It is made from virgin, low-density polyethylene and is sold in large rolls.
Besides its practical design, poly tubing is incredibly durable, strong, and suitable for safeguarding sensitive products from contaminants and other potentially harmful particles.
2. Materials
Cleanroom bags come in different materials that are convenient for various purposes and conditions. Therefore, you can choose among the following, depending on your specific needs:
Anti-Static Bags
Anti-static bags are widely used in the electronic industry. They are coated with an anti-static agent that lowers the risk of static imbalance, which often leads to electronic component failure. Anti-static bags prevent triboelectric charge buildup due to contact with fabric, hair, plastic packaging, etc. However, anti-static bags do not protect from ESD (electrostatic discharge).

ESD Bags
ESD bags ensure secure storage of printed circuit boards (PCBs) and other objects that could be affected by electrostatic discharge. ESD bags ensure the items inside the bag are safe from charges both inside and outside, even when they leave the ESD-safe area.
ESD bags are characterized by heat stability, transparency, ESD-shielding efficiency, permanent anti-static properties, and humidity-independent performance.
Polypropylene
Polypropylene is one of the safest cleanroom materials on the market. It is used to store foods and heat them in a microwave. Additionally, it is convenient for storing toys, plush animals, or even sharp objects.
Flexible Packaging
Flexible cleanroom packaging uses non-rigid materials like paper, foil, or plastics to make bags and similar flex containers for storing your products. For that reason, flex cleanroom packaging is a more cost-effective solution than other cleanroom packaging supplies. Flex cleanroom bags are commonly used in the pharmaceutical industry.
3. ISO Classes
Another factor worth considering when choosing cleanroom bags is the cleanroom class. The cleanroom classes are defined by ISO standards, which refer to the levels of cleanliness inside the cleanroom. The cleanliness level is further determined by the quantity and size of the particles per cubic meter of air.
The ISO &#;1 classification system is used across the US and Canada, and it classifies the cleanroom environments from the &#;cleanest&#; to the &#;dirtiest.&#; Remember that even the &#;dirtiest&#; cleanroom is still cleaner than a standard room.
The most common ISO cleanroom standards are:
· Class 100 (ISO 5)
· Class 1,000 (ISO 6)
· Class 10,000 (ISO 7)
· Class 100,000 (ISO 8)
4. Supplier You Can Trust
The last but not the least important thing is finding a reliable cleanroom packaging supplier. An ideal supplier must follow the standards and guidelines set by the leading institutions in the cleanroom field to prevent potential product failure resulting in substantial costs.
FAQs
What is the Difference Between Sterile Rooms and Cleanrooms?
Although sterile rooms and cleanrooms share some characteristics, they are not the same. Cleanrooms are defined as highly controlled environments in which a HEPA filter is used to filter the air from a certain number of contaminants and airborne particles. On the other hand, sterile rooms go a step further. Namely, sterile environments must be 100% free of bacteria and microorganisms. These areas are usually required for specific tasks that include injections, organ transplant solutions, vaccines, infusions, etc.
LDPE vs. HDPE Bags
The most distinguished difference between LDPE and HDPE bags is their material. LDPE bags have less tensile strength than HDPE but greater ductility. HDPE, on the contrary, are denser and have higher resilience than their low-density counterparts. Still, both types are used in the automotive industry, pipe protection, manufacturing, and various industrial applications.
