Lightweight, shock-resistant, portable, and durable: Plastics (such as HDPE, PET, and PP) have a much lower density than glass/metal, making them lightweight and easy to fit into handbags and suitcases. They are also impact-resistant and not easily broken, making them less prone to damage and leakage in outdoor settings such as the beach.

Low cost and mass production friendly: Plastic raw materials are readily available, and injection molding/blow molding processes are mature, resulting in unit production costs far lower than glass. Their lightweight nature also significantly reduces logistics costs, making them suitable for large-scale production and distribution by brands.

Chemical resistance and formulation compatibility: Materials such as HDPE and PP are chemically inert, tolerating the oil phase, emulsifiers, and UV filters (such as oxybenzone and avobenzone) in sunscreens, and are less likely to react. They can be made into opaque bottles to effectively block ultraviolet rays and slow down the degradation of active ingredients.
