Packaging

Vacuum packaging

Many food products including meats, poultry, coffee and produce are often packaged under vacuum in order to extend their shelf life. In Modified Atmosphere Packaging, MAP, a gas is introduced into a package to further modify the internal condition of the atmosphere and thereby ensure even longer lasting, high quality food ...

Labeling

Two fairly common methods of applying labels with vacuum are tamp-on labeling and blow-on labeling. Tamp-on labeling machines apply pressure-sensitive spot labels. A vacuum tamp pad is used to hold and place the label on the package after it is released from its backing sheet. The vacuum holds the label as the pad pushes (tamps) the ...

Pick-and-place

The use of robots for placing products in cartons and transfer of cartons and products between different stations in the packaging lines is very common in all industries. High speed pick-and-place robots for placing small items like candy and cookies in packages are often combined with a visual observation system for identifying products ...

Handling of flexible packages

Flexible packaging material is the generic term for soft packages made of film, foil or paper sheeting. Popular forms are stand-up pouches, bags, sachets and envelopes. These packages are often formed, filled and sealed in a vertical or horizontal form-fill-seal machine. The package is then finally put into a case by top loading, ...

Blister

A thermoformed blister or skin protects products and presents them in an attractive manner. In order to form the blister, vacuum is applied to a mold or series of molds. Heat and/or pressure may be applied to the topside of a flat blister while the mold cavity is evacuated, causing the container to form in the mold. Different levels of ...

Carton

Cartoners (carton erectors) are designed to construct cartons and containers from flat blanks made of flexible paper board or similar materials. Vacuum is used extensively to handle the paper board in various stages of the production process. Initially, flat cartons are stacked in a magazine or rack and held in place by rails or ...

Case & tray

Case erectors erect boxes from flat sheets of corrugated material. The erected boxes are then filled with products or individual cartons and prepared for the palletizing process. As with most packaging machines, suction cups, vacuum pumps and other pneumatic components are an essential part of the case erection operation. Advantages ...

Palletizing

Palletizing is the process of placing packages on a pallet. Palletizing machines use vacuum pumps, suction cups and other pneumatic components. These machines typically pick up multiple boxes at a time and place them on a stack. Today, because of the high speeds required, robots are often used to accomplish this task. Another vacuum ...
