Abstract:
The present disclosure provides a packaging process and the resultant package produced from the process. The process includes introducing, into a mixing device, pellets composed of ethylene/propylene/diene polymer (EPDM). The EPDM comprises greater than 60 wt % units derived from ethylene. The pellets have a residual moisture content from 500 ppm to 2500 ppm. The process includes adding a silica-based powder to the mixing device and coating at least a portion of the pellets with the silica-based powder. The process includes sealing a bulk amount of the coated pellets in a bag made of a flexible polymeric film. The process includes absorbing, with the silica-based powder, the residual moisture from the pellets, and preventing moisture condensation in the bag interior for a period from 7 days after the sealing step to 1000 days after the sealing step.
