Labthink Instruments Co., Ltd. info@labthink.com +86-531-85068566 Evaluation of Oxygen Barrier Properties in AluminumCoated Films Aluminum-coated films offer a cost-effective alternative to pure aluminum foil for packaging applications requiring good barrier properties. However, the effectiveness of these films can vary depending on the substrate material used. This study investigates the Oxygen Transmission Rate (OTR) of VMPET (vapor-deposited aluminum on PET) and VMBOPP (vapor-deposited aluminum on BOPP) to assess the influence of the substrate on barrier performance. The OTR test employed the coulometric method (equal pressure) following the standard ASTM D3985. This method utilizes a controlled environment chamber to measure the rate of oxygen permeation through the film sample.

Labthink Instruments Co., Ltd. info@labthink.com +86-531-85068566 Labthink C230H Oxygen Transmission Rate Test System was used for this study. This instrument is designed and manufactured based on the coulometric sensor method (aka. equal pressure method) and conforms to ASTM D3985. This instrument can be used to measure the oxygen transmission rate of barrier materials with high and medium barrier properties with high accuracy and high efficiency. Three specimens were cut from each VMBOPP and VMPET sample material using a sample cutter. These specimens were then clamped into the designated...
