Lower Production Cost: Plastic is generally much cheaper to produce than glass or metal. The raw materials and the manufacturing processes (like injection molding) are highly efficient and economical, especially at large scales.
Benefit for Brands: This allows for a lower final product price, making creams accessible to a wider market. It also frees up budget that can be invested in the formula itself or marketing.
Shatterproof: This is a primary advantage over glass. Plastic jars will not break if dropped, making them much safer for use in bathrooms (e.g., slippery wet hands) and for travel.
Benefit for Consumers & Brands: Reduces risk of injury and product loss. It also minimizes damage during shipping and handling, saving costs for manufacturers and retailers.
