Novapak Corp.: PET mason jar
Novapak’s new PET 26-oz, hot-fill container simulates traditional mason-style glass jars. Intended for sauces, salsas, jellies, preserves, peanut butter, mayonnaise, and other hot-filled products, it has a wide neck for easy removal of contents, and an indentation on both sides for easy handling and pouring.
Ribs on the front and back, together with a concave bottom, provide strength and maintain shape when the container expands during filling. Compared with glass, the PET jar significantly reduces breakage during production and shipping, and on retail and consumer shelves. It also offers economic savings and weighs 87% less. Jar is 6.2”H and 3.4 sq” with a 63-mm neck. It is molded of monolayer PET resin, weighs 48 g, and can be filled at temperatures to 185ºF.
