Milk bag packaging machine. A vertical form fill sealing machine is a type of automated assembly-line product packaging system, commonly used in the packaging industry for food and many other products. Walter Zwoyer, the inventor of the technology, patented his idea for the VFFS machine in 1936 while working with the Henry Heide Candy Company. [1]
Weighing machines: check weigher, multihead weigher [11] Wrapping machines: flowwrapping, stretch wrapping, shrink wrap Form, fill and seal machines , bags, pouches
These are designed for small bottles (similar to some of the flow fillers), but the hopper of the filler is set up to permit scan counting of tablets or candy pieces. [4] Positive displacement pump fillers: positive displacement, pump filling machines easily handle a wide range of container sizes, fill volumes and product types. While ...
little need to machine details; multiple features can be added simultaneously in 1 operation; [13] more economical for large production runs than traditional operations when additional machining cost and time are factored in (1000–20000 parts minimum, depending on secondary machining operations).

External vacuum sealers involve a bag being attached to the vacuum-sealing machine externally. The machine will remove the air and seal the bag, which is all done outside the machine. A heat sealer is often used to seal the pack. Typically these units use a dry piston vacuum pump which is often considered a "maintenance-free" pump.
The filling and grinding process steps can therefore be combined in a single machine. This means that the filling product is moved by the vacuum filler and, during filling, it is chopped to the final grain size within the grinding system. An important application for inline grinding systems is dry sausage or fresh sausage production. Minced ...
They are shaped to interlock when compressed and free flow when not compressed. They are roughly the size and shape of an unshelled peanut and commonly made of expanded polystyrene foam. 50–75 millimetres (2-3 in) of peanuts are typically used for cushioning and void filling packaging applications. The original patent was filed for by Robert ...
A foam pump. A foam pump, or squeeze foamer and dispensing device is a non-aerosol way of dispensing liquid materials. [1] The foam pump outputs the liquid in the form of foam and it is operated by squeezing. The parts of the foam pump, mostly made from polypropylene (PP), are similar to those of other pump devices. The foaming pump often comes ...
