Three-dimensional bag, also known as stand-up pouches, are an innovative form of composite packaging designed to stand stably without external support. Compared with traditional flat pouches, Three-dimensional bag is self-supporting through special structural designs on the bottom and sides (e.g., right angles at the bottom, curved bottom, or reinforced edges, etc.), which not only enhances the presentation of the package, but also facilitates its use and storage by consumers. Three-dimensional packaging bags are mostly made of plastic, aluminium foil, paper or other composite materials, processed through lamination or heat-sealing process to meet the packaging needs of different products.
