ANTI-BLOCK

Blocking is the term used to describe what happens when polyethylene film sticks together. Anti-block is an additive that roughens the surface of film at a microscopic level. This makes it easier for layers of film to separate. It makes bags easier to open.

ANTI-STATIC

For static sensitive applications – like packaging for electronic parts or for static sensitive automated packaging or mailing equipment – anti-static additives lower surface resistivity and static decay times.

HIGH DENSITY POLYETHYLENE

The chemical structure of high density polyethylene (HDPE) lends itself to greater toughness – roughly twice the tear and puncture strength and better chemical resistance than low density polyethylene (LDPE) and linear low density polyethylene (LLDPE). On the downside, HDPE film is less flexible and less clear than its LDPE and LLDPE cousins.

LOW DENSITY POLYETHYLENE

LDPE provides moderate strength and good clarity for general purpose applications. A commonly used type of LDPE is actually called Clarity.

LINEAR LOW DENSITY POLYETHYLENE

LLDPE provides better tear and puncture resistance for larger capacities or bulky objects. Two great options for LLDPE are Hexene and Octene.

HEXENE

Is a very strong linear low density polyethylene (LLDPE) that stands up to more rigorous demands. Hexene is the most common choice where added strength is important.
