A preliminary analysis of PET barrier technologies and mechanical performance related to a 3L PET wine bottle

The objective of this study was to test and compare Monolayer, Amosorb 2%, and Multilayer 3% PET wine jugs for package integrity and mechanical properties. In addition, two secondary package configurations were tested and analyzed. The first a shipper with load bearing inserts, the second configuration consisted of no inserts. Further, both shipping configurations and PET material have different costs associated. A Monolayer PET bottle has a savings of 17% a case compared to Amosorb and Multilayer PET bottle substrate. Shippers not utilizing inserts are $.20 less per case. The analysis was broken into three test and result phases. Phase I used compression testing to compare PET variables with two different shipper configurations. One shipper configuration was tested with load bearing inserts, the second with no inserts. The minimum compression force calculated was 500 lbs (based on warehouse stacking). Phase II testing included drop and vibration for secondary package configurations. Phase III tested primary package compression strength and drop testing. The results concluded both shipper configurations met the minimum 500 lbs compression force. Therefore a shipper with no insert is recommended for a savings of $.20 a case. Multilayer PET did not pass performance testing due to delaminating. Both Monolayer and Amosorb passed testing, however, Monolayer is recommended for production due to the 17% cost savings on material
