PPflessen are bottles made from polypropylene (PP), a versatile thermoplastic polymer. They are used in a wide range of packaging due to chemical resistance, relatively high heat tolerance, and toughness. PPflessen are common in foods, cosmetics, pharmaceuticals, and household chemicals, including hot-fill applications.
Manufacturing and design: PP bottles are typically produced by injection molding to form preforms, which are
