Preparation and Characterization of Easy Wrap Film Prepared from Domestically Polymeric Materials

Abstract

Easy wrap film has been widely used a single use film for dust free storage and COVID 19 prevention during the global pandemic. In the study, natural rubber (NR) latex was chosen as the domestic raw material for a coating application. Sulfur pre-vulcanized NR (PVNR) latex was prepared and purposely planned to be mixed with PVAc-co-PVA (Polyvinyl acetate-co-polyvinyl alcohol) or copolymer as the coating product for the proposed easy wrap film. Role of ratio between polymeric materials in physical, mechanical, thermal and weather resistant properties of the prepared films was elucidated. Ability of spark resistance of the easy wrap film prepared from the polymer mixtures prepared was tested.
