What is slip?
Slip is an additive that may reside in polyethylene resin or be mixed with a resin to alter its performance. When polyethylene resin is extruded, slip bleeds to the outside of the bags and increases the degree to which they slip, or glide. Slip makes bags easy to handle and prevents them from sticking to one another. High slip bags call for extra slip additive which increases the degree to which bags glide in any given process or handling, whereas low slip bags inhibit movement and promote grip.
