Sustainable polymer packaging engineering: The Coca-Cola CompanyRecent Research Landscape

Small-format PET containers lose carbonation rapidly through gas permeation and structural deformation, necessitating specific barrier and lightweighting geometries to maintain shelf life.

What technical problems is The Coca-Cola Company addressing in Sustainable polymer packaging engineering?

Preform thermal cooling inefficiency

(10)evidences

Mechanical friction and thermal stress during high-speed processing cause preform embryos to deform or adhere to equipment surfaces, leading to production defects.

Bio-polyester gas barrier deficiency

(9)evidences

Conventional PET containers exhibit excessive gas permeability and reliance on fossil-based feedstocks, leading to product oxidation and high carbon footprints.

Internal carbonation pressure deformation

(9)evidences

Lightweight plastic containers lose structural integrity and self-supporting stability when subjected to internal carbonation pressure or vacuum-induced sidewall paneling.
