With an increasing drive to reduce the volume of waste packaging, flexible packaging options are becoming ever more attractive, and there are some different flexible packaging formats to consider:
Tubes: this is one of the oldest forms of flexible packaging (toothpaste has been packaged in tubes since the 1890s), and the test of time has proven it a very effective packaging format.
Foil packs (sausages): man has been making sausage for hundreds of years, but automatic foil packing equipment (form, fill, and seal) is a relatively modern thing (first patented in the 1930s) and is one of the most effective ways to package higher viscosity materials (Pastes).
Pouches: can be formed into various shapes and sizes, with different folds, pleats, and welds. Some common Pouch designs are Three-sided, Stand-up, Block-bottom, and Quad-seal. Pouring spouts, screw caps, and resealing features are formed into the pouches for certain applications. Pouches typically lend themselves to lower-viscosity (pourable) liquids.
