PVC is shorthand for Polyvinyl Chloride. Traditional artificial Christmas tree needles have been made from PVC since they were first introduced to the market. The material is pressed into thin, rectangular needle-like strips and affixed by wire.
PE is shorthand for Polyethylene. This material is used in the creation of realistic, state-of-the-art trees that are modeled to replicate the appearance of real evergreens. Branch specimens are gathered from the forest, molded and then infused with the PE polymer to create the most lifelike trees on the market.
