Polyethylene terephthalate (PET) is a condensation thermoplastic from the polyester family, known for its high strength, good chemical resistance, and excellent barrier properties. It is one of the most widely used plastics globally, commonly applied in both packaging and technical uses.Polyethylene terephthalate (PET) is a condensation thermoplastic from the polyester family, known for its high strength, good chemical resistance, and excellent barrier properties.

• Food and beverage packaging: Bottles for water, carbonated drinks, oil, and trays or films for food.
• Textile industry: Polyester fibers for clothing, carpets, upholstery, and technical fabrics.
• Electronics: Insulating films, transformer tapes, and printed circuit board carriers.
• Automotive industry: Technical parts, tapes, protective films, and polyester
• based fabrics.
• Household products: Detergent bottles, microwaveable containers (with additives), cups, and decorative items.
• High mechanical strength and rigidity: Excellent impact resistance, tensile strength, and wear resistance make it suitable for more demanding applications.
• Good barrier properties: Low permeability to gases like oxygen and CO₂ helps preserve food and beverages.
• Chemical resistance: Resists many solvents, acids, and fats.
• Low moisture absorption: Retains dimensional and mechanical stability even in humid conditions.
• Recyclability: Easily recyclable and widely reused in packaging, textiles (polyester), and industrial parts.
• Not suitable for high heat: Its glass transition temperature (~75–85 °C) limits continuous use at elevated temperatures.
• UV sensitivity: Yellows and degrades under prolonged sun exposure without additives.
• Not inherently flame
• retardant: Requires additives to meet higher fire safety standards.
