When plastic polymer technology was not much in use Waxed Paper or card board paper was used to wrap soaps, cookies and a host of other fragile items. Wax makes the paper stiff, water resistant and moisture proof. Wax is environmentally benign and non toxic to humans. Even now as a green measure we see fruit juice packs on such cardboard papers.
- polyvinyl acetate (PVA), used in paints and adhesives, such as white glue, and. - polyvinyl butyral (PVB), used in safety glass films. What differentiates PVC from the other vinyls is the addition of a chlorine molecule (the. chloride âCâ in PVC and PVDC). Chlorine is the source of many of the environmental health. concerns with PVC, such as the generation of dioxin, a highly carcinogenic chemical produced in.
