Flexible packaging is a method of packaging products using non-rigid materials, which allow for more economical and customizable options. It is a relatively new method in the packaging market and has grown popular due to its high efficiency and cost-effective nature. Flexible packaging is any package or part of a package whose shape can readily be changed when filled or during use. It is produced from paper, plastic, film, aluminum foil, or any combination of those materials, and includes bags, pouches, liners, wraps, rollstock, and other flexible products. Flexible packages are particularly useful in industries that require versatile packaging, such as the food and beverage, personal care, and pharmaceutical industries. The benefits of flexible packaging include its sustainability, convenience, freshness, protection, and cost-effectiveness. Flexible packaging requires less water and energy to manufacture and transport, and it generates small quantities of greenhouse gases on its way to market, making it a sustainable packaging solution.
