Prices Still Rising for Volume Resins. 

 Global supply constraints on feedstocks and some resins, along with strong demand, are driving continued increases.

Prices of PE and PP moved up in double-digits, while those of PS, PVC and PET were also on an upward trajectory, in the first six weeks of this year. The remainder of the first quarter was projected to continue on this track, owing to global constraints on feedstocks and some resins, coupled by continued strong demand in most cases.
