PET Packaging: Addressing Environmental Challenges Through Recycling Innovation &Alternative Feedstocks Driving Future Growth

Polyethylene terephthalate (PET) offers superior packaging properties compared to alternatives, making it a preferred choice. Key advantages include high transparency, a glossy surface, excellent stability, strong pressure resistance, effective barrier properties, and light weight. It is widely recognized as the clear plastic of choice for packaging foods and beverages, particularly in convenient-sized soft drinks.

Despite growing environmental concerns, demand for PET bottles and rigid packaging continues to rise, according to a recent Smithers study.

While COVID-19 presents immediate challenges, advances in recycling technologies and the development of alternative feedstocks are projected to become increasingly critical over the next five years (2021-2026). The PET packaging market, valued at USD 55.52 billion in 2020, is expected to reach USD 74.2 billion by 2026, growing at a CAGR of 3.7% to 5% during the forecast period.

Challenges in Thin-Wall Products

● Filling Difficulties: Sharp Increase in Melt Flow Resistance Due to Thin Walls

● Flash & Mold Damage: Insufficient Clamping System Pressure Capacity

● Surface Defects: Flow Marks & Burn Marks Induced by High-Speed Filling

● Cooling Warpage: Non-Uniform Shrinkage from Wall Thickness Variations
