Glass bottles are extensively heavier than PET (e.G., 500 mL glass is ~15x heavier than PET). This results in higher transportation prices for glass because of elevated gasoline intake and freight prices, potentially costing as much as 5 times more than plastic. PET can result in significant shipping cost savings, potentially up to 30%.

Glass’s fragility increases breakage during shipping and handling, leading to higher operational costs and product loss. PET’s impact resistance significantly reduces breakage, minimizing losses and simplifying handling.
