Plastisol Coatings as Packaging Material

Packaging Plastisols are liquid polyvinyl chloride dispersions which can be applied by conventional means such as spraying, dipping, and flow coating. They can be applied in film thickness of 2–300 mils and can be made to foam to give strippable coatings ranging from a soft resilent type to a hard tough type. However, they must be fused at 300–350 F.

Plastisols have advantages of saving much space and labor. Also, they are fire retardant and resistant to exterior and chemical atmospheres.

Parts can be coated, fused, and stacked in times ranging 3–10 minutes.
