Plastics Today has published its polyethylene (PE) and polypropylene (PP) spot price report. They found PE up $0.04/lb last week, a trend “driven by soaring monomer costs and pointing to higher contract resin prices in February.” Ethylene shortages have played a role. Similarly, PP spot prices were up $0.02/lb last week. The rise in monomers shows “no abatement” at this point, especially since PP manufacturers have successfully passed along some recent cost increases.
