How does that work?

The www.howstuffworks.com Web site is both interesting and informative, and it offers packaging information.

I came across the site while conducting a search for UPC (Universal Product Code), and found the article How UPC Bar Codes Work .

The article was utterly fascinating, and told me things about the UPC I’d never known. I never knew how the check digit worked, yet this explains it in five easy-to-follow steps.

Out of curiosity, I typed in "packaging" and found articles including these: "How MREs (Meal, Ready-to-Eat) Work," and "How Offset Printing Works." The latter is a multipage primer filled with images.

The article "Why does lettuce in a bag stay fresh longer than a head of lettuce?" offers links to a number of articles about modified atmosphere packaging. Chock full of pictures, this selection may be helpful for someone in marketing.

There are many more pages for packaging-related things, such as "irradiation," which linked to a 10 different articles on food preservation.

If you’re in production or engineering, skimming through "How Marketing Plans Work" may be enlightening, even if only for the length of this scratching-the-surface summary.

The site is only fractionally as exhaustive in packaging as Packworld.com, for instance, but you may find something useful here. But watch out for getting sidetracked. I confess I searched using the keyword "URL" and found this: "How an Internet Search Engine Works." Gosh, I didn’t know that…

According to a Life Cycle Assessment (LCA), the carton format had the lowest environmental footprint of all the options, which compared PCR, molded fiber, glass, aluminum, and paper cartons. Using cartons to refill more durable rPET bottles makes the whole system bathroom- and shower-worthy, since the cartons themselves deteriorate in wet environments.

Dr. Bronner’s Paperboard Cartons Refill rPET Bottles to Ace LCA

Paperboard cartons get high LCA marks, but break down when wet. Meanwhile, 100% rPET bottles are circular, work great in the shower, and if they're refilled, are not single-use. Dr. Bronner’s refillable carton leverages both formats' strengths.
