Product catalog summary
Introduction
Recycling plastic bottles is crucial for environmental protection, but it can impact their oxygen barrier properties. This case study examines the effect of recycled content on the oxygen barrier properties of PET bottles, finding that increasing recycled content from 25% to 50% only slightly reduces their performance.
The Problem
Understanding how recycled materials affect PET bottles' oxygen barrier properties is essential, especially for food and beverage containers. High oxygen permeability can compromise product quality, limiting recycled material use.
The Test
Two PET bottle samples were tested: one with 25% recycled material and another with 50%. The coulometric method, as per ASTM F1307-02, was used to measure the oxygen transmission rate (OTR) at 23°C and 100% RH. The Labthink C230H Oxygen Transmission Rate Test System was employed for its high precision and automated control.
The Instrument
The Labthink C230H system features high precision, automated control, versatility, and data integrity. It can test up to three samples simultaneously and is compatible with various materials.
The Results
The OTR results were 0.01792 cm3/(pkg⋅day) for 25% recycled material and 0.01907 cm3/(pkg⋅day) for 50%. The slight difference indicates minimal impact on oxygen barrier properties.
Conclusion
Increasing recycled content in PET bottles from 25% to 50% only slightly diminishes oxygen barrier properties, suggesting that recycled content does not significantly compromise performance. The Labthink C230H system is effective for ensuring packaging quality, supporting sustainability in the industry.

Case Study: Oxygen Barrier Properties of PET Bottles Made of Recycled Material-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 www.labthink.com Case Study: Oxygen Barrier Properties of Recycled PET Bottles 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. The Problem 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. High oxygen permeability can compromise the quality of packaged goods, limiting the use of recycled materials in food and beverage containers. This study aims to quantify that effect by testing bottles with varying percentages of recycled content.

Case Study: Oxygen Barrier Properties of PET Bottles Made of Recycled Material-2

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 www.labthink.com The Test Two types of PET bottle samples were tested: one containing 25% recycled material and another with 50% recycled material. 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. The test conditions were set at a temperature of 23∘C and a relative humidity of 100% RH to simulate the environment of liquid-filled bottles. The samples were meticulously sealed onto...

Case Study: Oxygen Barrier Properties of PET Bottles Made of Recycled Material-3

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 www.labthink.com The Results The test yielded the following results for the oxygen transmission rates: • 25% Recycled Material: 0.01792cm3/(pkg⋅day) • 50% Recycled Material: 0.01907cm3/(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. Conclusion The study demonstrates that increasing the recycled content in PET bottles from 25% to 50% only slightly diminishes their oxygen barrier properties. The minimal...
