4 Classification4.1 This specification recognizes that polyethylene plastics are identified primarily on the basis of two characteristics, namely, density and flow rate (previously identified as melt index). The former is the criterion for assignment as to type, the latter for designation as to category. Other attributes important to the user for certain applications are covered…

AHP manufacture testing equipment for stretch-wrap films. Stretch wrap films are highly stretchable plastic films that are wrapped around certain items, as often used in the packaging industry. The main function of the film is to improve it’s loading stability for transportation, storage and contamination protection. Stretch-wrap films are commonly made of PE (LLDPE , VLDPE, PVC ….). Critical…
