Non-critical applications sometimes after cleaning process used in the converter level. This means that a translator will buy before manufacturing of packaging materials, usually polyethylene, then put it in a clean room cleaning and packaging. Typical is usually out of the material into the clean room to convert a EVA packing materials. This often leads to the end user in pollution level of particulate matter and additives are a lot of inconsistencies. After a cleaning process can remove the total pollution on the bag, however, the particles remain sealed edge and bottom of the packaging. In this type of program, these are impossible to eliminate.

Use the packing material is "clean" after EVA inherent problem is the lack of consistent resin (additive) as well as the role of molecular force, this will not be allowed to remove in the process of extrusion is drawn and combining to the smaller particles on materials and processing.

With the decrease of the particle size, strength increase with combination of particles to the substrate. Molecular inter-atomic forces increase one order of magnitude increases by two orders of magnitude. 700 micron sized particles, for example, has 1 G theoretical appeal, and the 70 micron sized particles is of 10000 G. Electrostatic force of these Numbers can be added several orders of magnitude.

Liquid detergents, such as deionized water or solvent cleaner, can be used in the cleaning process; However, in the process of cleaning, like any other clean process of clean room, for purity and sedimentary pollution again, you have the same concerns. Compatibility with selected cleaner material must also be determined.
