Anti Static Films: Polyethylene (LDPE & HDPE), Metallocene & Polypropylene

A Brief Introduction:

 

Materials such as paper, plastic and textile normally contain an equal number of positive and negative charges - that is, they are electrically balanced. Friction can disturb this balance, causing the material to become electrically charged. The level of charge is affected by material type, speed of contact and separation, humidity, and several other factors.

 

The electrical charge (static) will exert a force on nearby charged objects or a grounded conductor. Among the problems caused by this force are:

 


Charged conductors, like metals, discharge completely when grounded. Insulators, like plastics, do not conduct electricity and can not discharge when grounded. Grounded brushes or tinsel often have little effect on these surfaces.

Static charge built-up can attract dust onto a food package, which is undesirable aesthetically. At times, static charge can damage circuit boards in electronics packaging and may cause hazards of fire or explosion in the vicinity of flammable materials. The static charge may also cause processing problems such as difficulty in winding of films, or the agglomeration of powders during transport. Such undesirable effects can be avoided by using anti-stat master batch.

Plastic Films, such as polyethylene (LDPE & HDPE), metallocene and polypropylene (PP) can be made to resist static buildup on their surfaces. Blueridge manufactures anti-static films for all applications.

Food Contact
This material is composed of ingredients that are cleared by the U.S. Federal Food and Drug Administration (FDA) for safe use in Polyethylene and may be used in food contact applications subject to certain restrictions.
