— 1 — Product characteristics: PET’s advantages are prominentFrom the product perspective, PET bottles have significant advantages in transparency and appearance. Its high transparency enables consumers to see the product clearly, enhancing its appeal. In addition, PET bottles have better design and functionality, and can meet the packaging needs of different products. For example, in the fields of food, cosmetics, condiments, etc., the lightweight and high barrier properties of PET bottles make them an ideal packaging material. In comparison, although HDPE bottles perform well in terms of weather resistance, acid, alkali and salt liquid resistance, they are slightly inferior in terms of transparency and appearance. — 2 — Equipment efficiency: PET has high production efficiency In terms of equipment, PET bottles have h...
