Introduction: As a transparent plastic, it must first ensure high transparency, and secondly have good strength, impact resistance, wear resistance, heat resistance, chemical resistance, and low water absorption. Only in this way can it meet the transparency requirements during use, and cannot Any markings, pores, or whitishness. Defects such as halo, black spots, discoloration, poor gloss, etc. Therefore, during the entire injection molding process, great attention must be paid to the design of raw materials, equipment, molds, and even products. This article shares the injection molding characteristics of transparent plastics. And precautions, the content is for the reference of friends who purchase the excellent packaging material system:
