Straight-Sided Jar
The straight-sided jar has a consistent diameter from the base to the rim, with no taper or shoulder. This uniform profile makes it exceptionally easy to label (labels lay flat without wrinkling) and to fill on automated lines. Made from Type III soda-lime glass with thick walls and a wide mouth. Common neck finishes include 43-400, 53-400, and 58-400.
Straight-sided jars are popular across cosmetics (creams, scrubs, masks), food (nut butters, honey, spices), and candle making.
