Buyer's guide · Concentrate jars
Last updated: August 2026 · By TWO Packaging
Concentrate jars are one of those pieces of packaging most people never think about until they need them. But there is more going on with a good jar than it seems, so here is a quick rundown. 🍯
At the most basic level, a concentrate jar has two jobs: keep the product safe and keep it fresh. Everything else is detail.
Concentrates are sensitive to air, light, and heat. A proper lid seals tightly to help preserve the terpenes, texture, and potency, so the product a customer opens is the product you made.
Glass keeps the product inert and is the standard for premium concentrates. Food-grade plastic is lighter and more durable, which can be a better fit for travel or budget lines. Both have their place depending on your product.
Concentrate portions are small, so jars usually run in the five to nine milliliter range. Matching the jar size to the portion keeps things simple and avoids wasted space.
The jars come child resistant, so that side of things is handled without any extra effort on your end.
| What matters | Glass | Food-grade plastic |
|---|---|---|
| Product contact | Inert — keeps concentrate pure | Food-grade and safe |
| Feel & positioning | Premium, high-end | Practical, everyday |
| Durability | Can break if dropped | Lighter and more durable |
| Best for | Premium concentrate lines | Travel and budget lines |
