Packaging of food products has seen a vast transformation in technology usage and application from the Stone Age to the industrial revolution: 7000 BC: The adoption of pottery and glass which saw industrialization around 1500 BC. [4] 1700s: The first manufacturing production of tinplate was introduced in England (1699) and in France (1720).
Packaging engineering, also package engineering, packaging technology and packaging science, is a broad topic ranging from design conceptualization to product placement. All steps along the manufacturing process, and more, must be taken into account in the design of the package for any given product.
[3] [4] History of multilayered packaging dates back to the late 1950s when Procter & Gamble first designed multilayered collapsible tubes for toothpastes. Amine group containing products deforms HDPE on storage, and are incapable of arresting amine odours. Multilayered CO-EX bottles are the best packaging solution for such products. [5]
[4] Foam structures Several types of polymeric foams are used for cushioning, the most common being expanded polystyrene, polypropylene, polyethylene, and polyurethane. These can be molded engineered shapes or sheets which are cut and glued into cushion structures. [5] Convoluted (or finger) foams are sometimes used. [6]
The closure is often the most critical part of a package, and must fulfill all of the basic functions of packaging in addition to being easy to open and (if applicable) reclose. [3] Depending on the contents and container, closures have several functions:
Packaging operations can be designed for variable package sizes and forms or for handling only uniform packages, where the machinery or packaging line is adjustable between production runs. Certainly slow manual operations allow workers to be flexible to package variation but also some automated lines can handle significant random variation.
