Selecting the material depends on your brand positioning and target market. PET (Polyethylene Terephthalate) is the most popular choice for wholesale due to its high clarity, shatter resistance, and cost-effectiveness. For premium or eco-friendly lines, consider Glass, which offers a luxury feel and is 100% infinitely recyclable, though it increases shipping costs. For industrial or high-volume commercial use, HDPE (High-Density Polyethylene) is preferred for its superior chemical resistance and durability against impact.
