case study--Oxygen Barrier Properties of PET Bottles Made of Recycled Material

Recycling plastic bottles is vital for environmental protection, but it can affect their oxygen barrier properties, making them less suitable for oxygen-sensitive products. Our case study on PET bottles with varying amounts of recycled material found that increasing the recycled content from 25% to 50% only slightly reduced their oxygen barrier. This suggests that using more recycled material does not significantly compromise the bottles' performance.

  1. Case Study: Oxygen Barrier Properties of Recycled PET Bottles

  2. Balancing  • Sustainability and Performance • The growing trend of recycling waste plastic bottles requires an understanding of how reclaimed materials affect a product's performance. For PET bottles, a crucial metric is their ability to act as an oxygen barrier.

  3. Testing the • OTR of recycled  • materials • PET bottle samples  containing 25% recycled material and with 50% recycled material are tested. The testing was conducted using the coulometric method, a standard approach for measuring the oxygen transmission rate (OTR) of packaging materials, as outlined in standards such as ASTM F1307-02.

  4. C230H Oxygen Transmission Rate Tester • The test was performed using Labthink C230H Oxygen Transmission Rate Test System, which employs a coulometric sensor to measure OTR. • High precision: A resolution of 0.001cm3/(m2⋅day) and a container sample test range of 0.00005−1cm3/(pkg⋅day). Automated control: The system automatically controls and monitors temperature and humidity within a range of 10−55∘C and 5−100% RH. Versatility: It can test up to three samples simultaneously and is compatible with a wide range of materials, including various plastic films, sheets, and containers like bottles and barrels. • consectetur adipiscing elit donec a diam lectus sed sit amet ipsum mauris maecenas congue ligula ac quam viverra nec consectetur ante hendrerit.

  5. Result:  • Slightly different OTRs  • 50% • Recycled Material • 0.01907cm3/(pkg⋅day) • 25% • Recycled Material • 0.01792cm3/(pkg⋅day) • The findings showed that the OTRs for both samples were very similar, with the bottle containing 25% recycled material having a slightly better oxygen barrier property.

  6. Labthink  • encourages collaboration with packaging industry companies for quality control! • As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films.   • Contact us！ • trade.en@labthink.com • www.labthink.com
