Labthink Instruments Co., Ltd. info@labthink.com +86-531-85068566 Water Vapor Transmission Rate Testing of Tomato PeelBased Film The increasing demand for sustainable and biodegradable materials has led to a surge in research on plant-based alternatives to traditional plastics. Tomato peels, a byproduct of tomato processing, offer a promising source for the development of such materials. This study focuses on the water vapor barrier properties of a film made from tomato peels, a critical factor for various applications, including food packaging and medical use. To determine the water vapor transmission rate (WVTR) of the film, the cup method, also known as the gravimetric method, was employed. Labthink C360H water vapor transmission rate tester was used for this purpose. The testing procedure involved placing the film between a desiccant-filled cup and a lid, creating a sealed chamber. The testing procedure involved placing the film between a desiccant-filled cup and a lid, creating a sealed chamber. The equipment then measured the weight change of the cup over time to determine the WVTR. The WVTR of the tomato peel film was found to be 72.317 g/(m²·24h). While this value indicates a moderate water vapor barrier, it may not be sufficient for applications requiring high levels of moisture resistance. 1

Or applying coatings or treatments to the film's surface can create a more effective barrier against water vapor. Tomato peel-based films offer a sustainable and biodegradable alternative to traditional plastic films. However, their water vapor barrier properties may need to be improved for certain applications. Future research and development efforts will be crucial in optimizing these films for various uses. As the demand for functional packaging materials...
