We offer free ASTM D 1238 Melt Index testing to our customers.  Once standard strength, rigidity, and other physical testing is completed on plastic returnable containers design, it is important to make sure that the quality of plastic meets all specifications, including melt flow.

​

Melt Index testing is not a perfect tell all of plastic quality, but it is an excellent indicator to determine the amount of virgin resin to regrind ratio used to make a container.  Deviations from the specifications can dramatically reduce the lifespan of returnable plastic containers.
