Types of Plastic sheets
The most flexible plastic sheeting polythene sheeting available is Linear Low Density Polyethylene (LLDPE). Most commonly used, these sheets are softer, comfortable for handling and have greater tensile strength. The thickness range of these pliable sheets is between 0.5 Mil and 40 Mil. The Medium Density Polyethylene (MDPE) is least commonly used. It is more resistant to chemicals and is stronger than LDPE. MDPE sheets are also flexible and more resistant to punctures and tears. The strongest plastic sheet is High Density Polyethylene (HDPE). In addition to its strength, these sheets can be used to get protection from harmful UV rays.
