The design of plastic packaging for fruit and vegetable juices involves considerations such as material selection, barrier properties to prevent spoilage, ease of use, and environmental sustainability. It also includes factors like branding, shelf-life extension, and cost-effectiveness. Various types of plastic materials, such as polyethylene terephthalate (PET), high-density polyethylene (HDPE), and polypropylene (PP), are commonly used. The design aims to maintain the quality and safety of the juices while offering a practical and appealing package for consumers.
