This chapter will discuss the different types of packaging machinery and equipment used.

Packaging Machinery
The different types of packaging machinery include:

Filling Machines
Filling machines or fillers are utilized for packaging, mostly for beverage and food but for other products also. These are used to fill either a pouch or a bottle, depending on the product. The following are the most popular.

Auger or Agitator Filler
Augers or agitator fillers are made to fill dry mixes, like flour and sugar. The fillers have a hopper in a cone's shape which holds the mix and fills it in a pouch utilizing an auger conveyor which the agitator controls.
The mix is put in a pouch which is made from poly or paper which is made in a collar and the pouch is sealed by a consecutive number of dies and heaters. The interface which has the process applying the powder is of key importance to guarantee an efficient filing.

Vibratory Weigh Fillers
These offer a blend of speed, versatility, and accuracy for linear feeders. Every weighing-hopper is constructed to accommodate the requirements for precise weights.

Flow Fillers
Constructed for oils, liquids, and thin edible products. These fillers are constructed when they fill a tub or bottle that enters the machinery. This emits the open bottle back on another conveyor machine for sealing.

Tablet Fillers
These are constructed for products which are counted by portions instead of weight. These are constructed for small bottles like other flow fillers. The filler's hopper is set up to allow scan counting of candy pieces or tablets.

Positive Displacement Pump Filler
Positive displacement, pump filling machinery handles a broad range of container dimensions, fill volume, and types of product. While originally constructed for filling gels, lotions, and creams, these fillers also accommodate water heavy and thin paste products.
Some of the products this machinery simply fills are heavy sauces, cosmetic creams, hair conditioners and thick shampoo, honey, paste cleaners, hair gels, and car wax.

Vertical Form Fill Sealing Machine
Vertical form fill sealing machinery is a type of automatic assembly line packaging system, normally utilized in the food packaging industry, and a wide range of other products. The machine makes stand-up pouches and plastic bags out of a flat film roll, while filling the bags simultaneously with products and sealing filled bags. Both liquids and solids can be bagged utilizing this packaging system.
The machinery is loaded with a continual flat plastic film roll, which has had labeling and artwork on the interior or exterior of the film. While plastic is the most normally utilized packaging material in the food industry, the machinery can also be utilized to make continuous metalized paper, film/foil, and fabric products vessels by altering the edge seaming/sealing methods. For other products the film might first be put through a sterilizing chemical wash and drying before using in the packaging system.

Straddle Wrapper
With straddle wrappers a load stays fixed while a wrap applying system rotates around the load. This type of wrapper wraps light weight and heavy unstable loads and is able to wrap low to high volumes.

Orbital Wrapper
Orbital wrappers are also referred to as "ringer" wraps the pallet by going under and over the load as the load moves on a conveyor machine into the machinery. Orbital wrappers are mainly utilized for packaging oddly shaped or flattened products like rolled carpets, pipes, and windows.

Ring Straddle Wrapper
These are fast wrappers that are typically capable of wrapping 200 loads an hour. These machines are at times found in the beverage and toiletry industries. They are exceedingly specialized equipment and only contribute a small part of stretch wrapping machinery presently in use.
They enable the load to stay fixed while the wrap applying system rotates around the pallet.

Shrink Tunnels
A shrink tunnel is a staple of many packaging lines. When configured with the correct temperature settings, it is a packaging powerhouse. It works by conveying a product that has been put inside a shrink bag produced from a shrink film via a hot tunnel which causes the heat sensitive film to shrink evenly around the item inside.
Airflow from the machinery avoids the products from becoming too hot. If a product is mostly sensitive, particularly heat sensing tapes are put through the machinery to identify if the product is suitable for packaging using a heat tunnel.
If the tapes identify that the heat tunnel is inappropriate for packaging a product, other choices can be recommended by the packaging professionals.

Carded Packaging Machines
These put products into a plastic shell which is backed either by a blister board piece or another plastic piece. The three kinds of carded packaging are skin packs, blister packs, and clamshells. Skin packs and blister packs have plastic shells which are built-in with blister board backers and clamshells are entirely made from plastic shells which close as their namesake shellfish.
For numerous goods, carded packaging like skin packs, blister packs, and clamshells give safety dynamics or a visual appeal which won't be gotten otherwise. Blister packs are usually utilized to package fishing lures since they provide safety from the hooks at the same time giving a clear window to see the product contained inside.
Skin packaging has a particular shelf appeal for tools like wrenches, pliers, screwdrivers, and hammers. As skin packs are frequently sealed to fit the outline of the product inside, they enable potential customers to more closely see the package contents physically and also hold the product within securely.

Blister Packaging Machines
They come in semi-automatic and automatic models. They have rotating sections which hold the plastic part of the blister pack in position.
As the section of the machinery rotates, empty plastic shells either automatically or manually are filled with the product. Next, blister board backers are put on the plastic shell's back either by machine or hand with a glue and the blister pack is done.

Skin Pack Machines
While blister packs and skin packs share similarities, the machinery that makes the two are very different. Skin pack machinery has a platform for resting the backing substrate or blister board. The products to be packaged are placed on the board.
The machine puts a heated soft plastic layer which shapes itself over the products. Vacuum sealing is often implemented to guarantee a tight fit. The substrate then binds to the heat-seal layer on the cardboard.

Clamshell Machines
There is a distinctive dissimilarity between blister and clamshells packs. Clamshells are a one-piece molded plastic having a hinge. They could be sealed by a number of ways including staples, pressed fit closures, buttons, RF, heat, etc.
Clamshell machines have an automatically closing the lid that could be done but needs a lot of space.

Case Erectors
These are machines which erect or unfold cardboard boxes for filling with products. There are manual, automatic, and semi-automatic types of this machine. On a manual machinery, a human is needed to unfold a box, fold it or tape the box flaps into shape by a taping machine or by hand and the box is handed to the next worker or sent through a conveyor.
Semi-automatic erectors carry out the third and second stages automatically through a conveyor machine which conveys the box via areas which force it into the exact shape. The erected box is now conveyed to a pile by conveyor machine or by hand.
An automatic case erector utilizes mechanical components like a robotic arm to take a box from the pile, unfold, and put it onto an automatic conveyor machine. The box then moves through the conveyor machine and it is filled with the products and sealed either by easy human interaction or mechanically.

Proper packaging machine maintenance is critical to the longevity and performance of your packaging machinery. A well-maintained machine will serve you and your operations for many years to come.
