Packaging

Food packaging provides protection, tampering resistance along with special physical or chemical requirements. It bear nutrition facts and other information about food. There are several packaging processes.
 

Blister Packaging: Blister pack is a term for several types of pre-formed plastic packaging used for small consumer goods, foods, and for pharmaceuticals. Immediately after filling the product, it needs to be sealed. In the case of pharmaceuticals, aluminium foil is used. The medicine and aluminium foil are heat-sealed using gas by the mutually parallel heat-sealing roller and the anilox roller under the action of a certain temperature and pressure. The time is extremely short when the material passes through two rolls, so as to obtain a qualified heat-sealing effect
 

Heat Sealing: Heat sealing is the process of sealing one thermoplastic to another similar thermoplastic using heat and pressure. A gas fired heat sealer machine is used to seal products, packaging and other thermoplastic materials. The most common method of heat sealing utilizes a sealing bar to apply heat to a specific area to seal or weld the thermoplastics together. Heat sealing is used for many applications, including heat seal connectors, thermally activated adhesives, film media, plastic ports or foil sealing.
 

Cartoning:  A cartoning machine is a packaging machine that forms  Carton packaging gives products a long shelf life due to the three special layers (the plastic layer, the paper board and the foil). Once the printing is done on the paper board a worker feeds it into a lamination machine which joins it to a plastic and foil layer. A gas flame heat treats the paper board to ensure adhesion to the plastic layer. The laminator extrudes liquefied plastic between roll of aluminium and the heated paperboard. The rollers squeeze all the layers together, thus, forming the carton. Gas fired boilers are also used to produce steam used in sterilization prior to filling the cartons (especially done for food and pharmaceutical industry).
 

Shrink Wrapping:  Shrink wrap is a material made up of polymer plastic film. When heat is applied, it shrinks tightly over whatever it is covering. Heat can be applied with via gas fired heat guns or products along with the sterilized shrink film can pass through a tunnel heated using gas on a conveyor.
