Stand up pouch bags have a multiple layered structure. This structure provides effective protection against moisture and other environmental impurities that can ruin sensitive electronic equipment. A use of foils and other materials provides protection against high energy rays from the sun which can destroy the sensitive sensors of the electronic product.
Electronic product manufacturers can enhance protection by adding more layers of plastic. This keeps the product secure in two ways – it makes it more difficult for even the tiniest dust particles and impurities to pass through the packaging and come into contact with the electronic product. Second, more layers act as a cushion. This quality is especially useful in situations where the product is fragile and can break on falling from even a small height.
