Packaging Weight, Filling Ratio and Filling Efficiency of Yogurt and Relevant Packagings Depending on Commercial Packaging Design, Material, Packaging Type and Filling Quantity

Yogurt is a diverse dairy product category. It available in different packaging designs made of materials. To identify potential for improvement these packagings, better understanding about used materials and efficiencies necessary. For this study, 150 products some yogurt relevant desserts were bought from various supermarkets, street markets discounters the Munich region (Germany) spring 2022. Commercial types are cups, buckets, pouches, bottles, glass packagings bricks. The filling ratio most above 70%, rest volume headspace. Poly(1-methylethylene) (PP) poly(1-phenylethene) (PS) dominate as main packaging. bottle poly(ethylene terephthalate) (PET) polyethene high-density (PE-HD) used. Interestingly, poly(lactic acid) (PLA) not found. Closures (caps) responsible 5 to 30% total weight.

With increasing weights, we observe tendency towards higher efficiencies. By using paper/carton wrapping reduced whole
