Corrosive Environment:


Companies that package corrosive materials need to take special care when purchasing their packaging machinery, so that the machine isn’t damaged or ruined by the product being packaged. These types of machines are made out of a different material so that they won’t break down when processing these corrosive liquids. These machines are typically constructed from HDPE—high-density polyethylene. This material is designed to resist damage from a highly corrosive environment, where normal metals would typically dissolve. The other biggest challenge is to prevent corrosion, especially in a closed environment such as a filling process. It is very difficult to control the parameters influencing corrosion, such as the chemical composition of the product, its temperature, abrasiveness, pressure and fluid velocity.


Therefore, it is advisable to choose a material that does not corrode in the environment considered. Usually, this can be achieved by replacing the 304 stainless steel with chemical resistant plastics such as polyethylene or polypropylene, 316L, titanium or even hastelloy in some specific cases.


These machines, since they’re built to be able to stand up to this wear and tear, will last for years in your packaging line without damage, all thanks to the special design and materials used for building them.


Some common products that require the use of corrosion-resistant machinery include cleaning products, pool chemicals, bases such as sodium hypochlorite, acids such as hydrochloric acid, and any other corrosive liquid.
