High Density Polyethylene (HDPE)

   HDPE is the most widely used resin for plastic bottles. This material is economical, impact resistant, compatible with a wide range of products (including acids and caustics) and provides a good moisture barrier. It is usually supplied in FDA approved food grade. When fluorine treated, HDPE becomes an effective package for solvents (aromatic hydrocarbins) and oxygen sensitive extracts.

   HDPE is naturally translucent and flexible. The addition of color will make HDPE opaque although not glossy. Adding extra light to the bottle will yield a rigid container. HDPE is supplied surface-treated on a stock basis and lends itself readily to silkscreen decoration.

   While HDPE provides very good protection at temperatures below freezing, it cannot be used with products filled at over 180?F or products requiring a hermetic seal.
