Summary: Learn how the food industry utilizes the process of deposition.

In the food packaging industry, plasma-enhanced chemical vapor deposition (PECVD) and Physical Vapor Deposition (PVD) are both important applications that are widely used throughout the industry.

Two of the most important types of application in food packaging in regards to coating are silicone oxide and amorphous carbon solely based on their properties.

PECVD is a process where a thin film is produced on top of a particle. It utilizes plasma to allow for deposition at lower temperatures. The process consists of a substrate, the target, being layered with a film that starts out as a gas but through chemical reactions becomes a solid. The food industry has been using this type of technique for a long period of time which proves how efficient it has been – and still is today.

PVD is a physical method that also creates a thin film but does not involve chemical reactions. These types of thin films take on the appearance of foil, but are a lot stronger and thinner. In the food industry, these metallization processes were used for microwave-heating susceptibility purposes. This method continues to be utilized today and has become a basis for further enhancement and research to uncover more efficient techniques.

Another application still used in the food industry today is thin film evaporation which, hence the name evaporates the thin film coating from a liquid to a gas. Done through heat and mass exchangers, these types of evaporators give workers the ability to retain certain physical and chemical features needed when packing food.

Douglas Engelbart and Modern Computing

These days, most of us interact with computers which means that almost all of us use a mouse to interact with elements we see on the screen. That human-computer interaction is the brainchild of Douglas Engelbart, who was one of the earliest pioneers of the power of the Internet.

He worked with the Augment Research Center Lab, where he pioneered the study of how humans interacted with computers. There, he developed important ideologies that guide much of computer usage today. Aside from the mouse, Engelbart also helped to develop a pre-cursor to the graphical user interface.

During the early 1950s, he stopped thinking about his career in the typical sense and moved away from the concept of a “steady job”. He believed his talents were best focused on solving the world’s complex problems. He thought very hard about how best to do this, and he ultimately came up with the idea that augmenting human intelligence was the only true method forward. As a result, computing became dear to his heart.

Engelbart’s philosophy was that tools needed to be improved constantly for there to be any kind of human progress. He was vocal about developing computer networks to exchange information, and emphasized the importance he felt computers had in the modernizing world.

Engelbart was prominent throughout the 1960s and 70s. He was able to gain funding for most of his concepts, which enabled him to work on ideas he’d cultivated for decades. Unfortunately, that funding and interest dried up in 1986. He retired and lived a quiet life until his death in 2013.
