There are a number of extremely sensitive business operations that require extra protection from contamination of airborne particulate. They need special packaging that will not only keep it clean from visible dirt but also from ultra-fine particles. This is where Clean Room ISO Certified Bags prove essential.

When measuring the size of a suspended matter, we use the term micron. .One thousandth of one inch (.001 or 1 mil) equals twenty five microns or .0000394 inches. Measurements of contamination usually base their measurements using particles measuring one half micron (.5 microns) or .0000196 inches.

As an example of relative size, a human hair measures approximately 40 microns in diameter while dead skin particles that shed from a human body can measure anywhere from 1 to 1,000 microns. Particles of dust are about 1 micron with bacteria anywhere from 0.3 to 10 microns. Now remember, our cleanliness levels are based on ½ of a micron.

Federal Standard 209E basically classifies a number units of cleanliest levels which are as follows:

• Class 100 as the level of cleanliest that has no more than 100 particles in one cubic foot of air which is over .5 microns.
• Class 1,000 as the level of cleanliest that has no more than 1,000 particles in one cubic foot of air which is over .5 microns.
• Class 10,000 as the level of cleanliest that has no more than 10,000 particles in one cubic foot of air which is over .5 microns.
• Class 100,000 as the level of cleanliest that has no more that 100,000 particles in one cubic foot of air which is over .5 microns.

The measurement levels go down to class 10 and class 1. Class 1 usually operates in an environment which necessitates the use of robots rather than human persons in order to maintain that level of cleanliness.

Our greatest number of requests for clean ISO certified film and bags is class 100. To conform to this, we must manufacture the bags and roll the film (through a web cleaner) in a class 100 environment. By using filtered super clean nitrogen in the bubble and additive free (barefoot resin) resin, we arrive with an interior surface classified as a level 100.

If your business requires the use of ISO certified clean room bags, contact Atlantic Poly, Inc. We manufacture ISO certified bags and roll films available in various materials.
