Material characteristics of Laundry Detergent Plastic Bottle ‌Polyethylene (PE): The common PE material in laundry detergent bottles is usually high-density polyethylene (HDPE). HDPE has the characteristics of acid and alkali resistance, corrosion resistance, low water absorption, high density, strong pressure resistance, good mechanical properties, strong wear resistance, and is non-toxic and odorless, and very environmentally friendly. ‌Polypropylene (PP): Although not as common as HDPE, PP material is also commonly used in the production of laundry detergent bottles, with the characteristics of light weight, durability, and chemical corrosion resistance.
