What Happens to a vinyl binder in different weather conditions?
Vinyl (poly-vinyl-chloride or P.V.C.) is a type of plastic, and like most plastics, will soften when heated. A vinyl binder left in a hot car or in direct sun will expand and appear “baggy”, no longer tight against the board. Vinyl also becomes hard and brittle when exposed to cold. So much so, that the material may actually crack or split. If you are using your binder outdoors, or for a mailing list, it is recommended you choose a casemade Metro-case® binder, or laminated reinforced printed paper material on a heavy one-piece grooved binding board. These types are manufactured to withstand a wide range of temperature extremes.
