Today just now while I was filling rice into a polythene bag. I noticed that some grains inside the polythene bag were sticking to the sides of the bag. I tried to replicate this on the outside of the bag and got positive results.
I am now searching for a reason as to why this is happening. My guess is that static electricity is involved. However that raises the question how does filling rice in a plastic bag result buildup of charges on the rice grains and polythene.
what factors can cause rice grains to stick to polythene bags and how ?
