MATERIALS

LDPE – virgin low density polyethylene, complies with FDA & USDA food packaging requirements with excellent strength in cold temperatures.  May need an EVA additive for freezer applications.  This is traditional material for most applications.

LLDPE – linear low density, stronger than LDPE with greater puncture resistance.  Also complies with FDA & USDA.

HDPE – high density, for use in retail and industrial applications such as trash liners.

BOPP – stretched polypropylene, preserves freshness with vapor and moisture barriers.  A glossy, high transparency film excellent for product presentation.  Think flower sleeves and snack food bags.

Pink Anti-Static – prevents static creation

Transparent Metal Shielding – Faraday Cage protection, blocking external static charge.  Used for shipping open circuit boards, etc.
