44.0oz /1.3L 89-400 PET Square Jar

What this packaging is

Square geometry and 1.3L of food-safe PET capacity make this 44oz jar a practical workhorse for high-volume dry food, protein powder, vitamin, and specialty food packaging. The 89-400 neck finish opens compatibility to a wide range of standard closures, while the flat-sided silhouette stacks efficiently on shelves and ships more economically than round alternatives. Supplied from U.S. warehouses, the 44.0oz / 1.3L 89-400 PET Square Jar cuts lead times for domestic brands and supports decoration via labeling or Tampo Pad Print. Available with PCR content for brands building toward more responsible material sourcing. A clean, substantial format that lets large-format food and wellness products show up confidently at retail.

Why brands choose this

• Square silhouette delivers real shelf and shipping efficiency: Flat sides allow tighter shelf facings and more efficient case packing than round jars of comparable volume — a meaningful cost and space advantage for brands selling through retail or DTC with high shipping volume.
• Spans high-growth food and wellness categories in one format: From dry grains and protein powders to vitamins, prepared foods, and plant-based products, this jar's 89-400 finish and large capacity serve a wide development range — useful for brand teams managing multi-category product lines without multiplying component vendors.
