Because of higher demand, lower inventory levels and lower production rates, polyethylene (PE) resin costs have been increasing steadily. Although GF and its suppliers have been absorbing some of these costs for the last 12 months, the increases will be driving prices higher in the early part of 2012. Pregis (see below) has announced a 7% increase as of April 2, 2012 and other suppliers will likely be following suit.
Note that increases in petroleum products will also affect plastic strapping products.
