A key application area for Polyethylene Terephthalate remains rigid packaging, especially for beverages. The demand for single-serve bottled water, soft drinks and convenience packaging continues to lift volumes. According to studies, packaging constitutes the largest end-use for PET globally, making up a significant portion of resin consumption. 

In addition to packaging, textile applications through PET fibers contribute meaningfully to the overall market. While packaging remains the dominant segment, diversification into specialty films, engineering plastics and other value-added areas supports growth. The interplay between volume applications and higher-value niches underscores PET’s broad appeal.
