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.
