The primary reasons for using various packaging bags for sports supplements include protecting the quality and properties of the product, branding, and advertising. These bags not only shield the raw materials from environmental damages such as moisture and light but also help provide precise and appealing information to customers. Therefore, stand-up zippered bags and box pouches made from materials such as paper, double-layer transparent films, and triple-layer aluminum or metalized films are selected based on the type of sports supplement and the need to maintain product quality.
(The best choice for sports supplement packaging is double-layer bags (polyester and polyethylene) in stand-up zipper and flat-bottom formats, featuring a transparent window for product visibility.)
