Idealpak 34oz/1L 89-400 HDPE Single Wall Straight Sided Jar

What this packaging is

Wide-mouth functionality and a straight-sided profile make this 34oz/1L HDPE jar a workhorse for high-volume powder fills. The 34oz/1L 89-400 HDPE Single Wall Straight Sided Jar is built from durable, chemically compatible high-density polyethylene and features an 89-400 neck finish that plays well with induction-seal liners and tamper-evident caps — both standard requirements in supplements and sports nutrition. The straight-sided body gives you maximum label real estate, which matters when you're competing on shelf in the protein powder or vitamin category. A natural fit for brands scaling up fill lines without sacrificing flexibility.

Why brands choose this

• 89-400 neck finish opens up your closure options: The 89-400 thread is one of the most widely supported specs in supplements packaging, meaning you can pair this jar with induction-seal liners, tamper-evident caps, or flip-tops without custom tooling — a real time-saver when you're qualifying components across multiple suppliers.
• Straight-sided body maximizes on-shelf label impact: Unlike tapered or contoured jars, the flat cylindrical profile gives you uninterrupted, printable label space from top to bottom — critical in the protein powder and sports nutrition category where ingredient panels, branding, and claims all compete for real estate.
• HDPE construction handles demanding fill environments: High-density polyethylene offers strong chemical resistance and durability under high-speed filling conditions, making this jar a reliable choice for powders, granules, and supplements that require moisture control and consistent structural integrity throughout the supply chain.
