ПЭТ в бутылках для воды: подробный обзор его состава и применения

PET (polyethylene terephthalate) is a pharmaceutical product widely used to manufacture a variety of plastic packaging, including water bottles, food containers, and pharmaceutical packaging. This material has inherited a reputation for unique properties and uses that have made it famous worldwide. Plastic has become one of the preferred materials in the packaging industry.

Composition:

  • PET is a thermoplastic polyester with terephthalic acid (TPA) and fillers (EG). It belongs to the polyester family and is manufactured through a polycondensation reaction.

CHARACTERISTICS:

  • PET’s high strength, lightweight, chemical resistance, and good sunlight resistance make it an ideal choice for packaging materials. In addition, PET has good transparency and luster, enabling it to create texture and color for display products.

Uses:

  • PET is particularly common in water bottle applications because it is durable, lightweight, and clean of bisphenol A (BPA). It also manufactures food containers, pharmaceutical packaging, cosmetic bottles, and industrial products.

PET’s composition and uses make it a material of choice in the plastic packaging industry. It offers an excellent combination of properties, including strength, durability, and safety, making it the material of choice for various applications, from water bottles to pharmaceutical packaging.

 

Advantages of PET in water bottle applications: lightweight and durable

Although PET is widely evaluated in a variety of plastic packaging areas, it is particularly favored in the water bottle sector due to the following significant advantages:

Lightweight:

  • PET is a highly lightweight material, making it ideal for water bottles as it reduces transportation and carrying burdens.

Долговечность:

  • PET’s excellent impact resistance allows it to withstand accidental bumps and drops during daily use, ensuring water bottles won’t break or be damaged easily.

Heat Resistance:

  • PET is heat resistant and can withstand temperatures up to 70°C, making it suitable for holding hot and cold beverages without deforming or releasing harmful substances.

TRANSPARENCY:

  • PET is a highly transparent material, allowing consumers to see the content and color of the liquid in the water bottle and monitor the amount of beverage consumed.

RECYCLABILITY:

  • PET is a recyclable material that is environmentally friendly and reduces the production of plastic.

PET’s lightweight, durability, heat resistance, transparency, and recoverability in water bottle applications make it an ideal material widely preferred by consumers and manufacturers.
