A stand-up spout pouch is a modern flexible plastic package that stands out for being compact, effective in presentation, foldable and recyclable. Its bottom has a horizontal support structure so it stands on its own; it can take a zipper or a straw, is pressed from PET and other materials, and an extra protective layer can be added.

Soymilk packaging takes forms such as single-layer plastic bags, spout pouches, stand-up spout pouches, composite plastic packs, PET bottles, gable-top cartons, Tetra Pak cartons and cans. Quality control hinges on the sterilisation process: aseptic and vacuum packing are the two common methods, and leading manufacturers use the instantaneous ultra-high-temperature sterilisation of aseptic packaging.

Bag breakage in spout pouch production occurs mainly at bag making and spout insertion. Punching, bottom gusset forming and bottom sealing need close attention, and the joint between four layers and two layers is the most breakage-prone area, calling for an extra heat-sealing bar. A spout pouch also needs good opening performance, low surface friction and no static.

Food packaging material basics: the inner layer is usually PE or CPP, the outer layer PA or PET, the middle layer possibly EVOH or PVDC, and aluminised film or aluminium foil is also used. PP and PE contain no plastic additives; PE and CPP seal easily, PA and PET print well, PVDC and EVOH offer good barrier properties, and aluminised film and foil block light.
