The site also showcases polyethylene terephthalate bottles for water and beer applications, as well as glass food jars. One of the best parts of the site is a glossary including more than 40 glass bottle manufacturing-related terms that should be required reading for glass buyers.
Buyers of flexible packaging materials may want to check out the site of Dunsirn Industries (Neenah, WI), at www.dunsirn.com. The site features two on-line packaging calculators--one for computing the length of a roll of packaging film given the roll and core diameter and the film thickness. Another calculator computes the weight of a finished roll of packaging film given the roll and core diameters, plus the roll width and material density. Both calculators work with either metric or English measures. What makes these calculators especially useful is that they can be used by any packager, for any flexible material, regardless of whether Dunsirn converts your packaging film--a generous contribution to the packaging public.
