Best Containers for Cannabis Concentrates: Glass vs. Silicone vs. Plastic
Written by Lia Thompson, packaging specialist at Creative Labz. Last updated October 3, 2026.
Wax, shatter, live resin, badder, and distillate are some of the most valuable cannabis products per gram, and some of the easiest to ruin with the wrong container. Concentrates are sticky, sensitive to heat and air, and full of volatile terpenes that escape through a poor seal. The container you choose decides whether a dab tastes the same in week six as it did on day one.
This guide compares the main concentrate container materials (glass, silicone, plastic, parchment, and syringes), explains why airtight packaging matters, and covers the more sustainable options.
What Concentrates Need from a Container
- An airtight seal. Air exposure oxidizes cannabinoids and evaporates terpenes. Some concentrates also change texture, like shatter turning to sugar, when exposed to air and warmth.
- A non-reactive surface. The material shouldn't absorb oils or terpenes or add anything to the product.
- Easy access. Sticky products need a wide opening or a non-stick surface so customers can actually get them out.
- Protection from light and heat. Both speed up breakdown.
- Child resistance. Required for concentrates in many legal markets.
Concentrate Container Materials Compared
Glass Jars
Glass is the standard for retail concentrate packaging. It's fully airtight with the right lid, completely non-reactive, doesn't hold odors, and looks premium. Child-resistant glass concentrate jars in 5mL and 7mL sizes cover most one-gram products, and larger jars handle bulk. The main drawback is that very sticky products can cling to the sides, so wide-mouth jars help.
Silicone Containers
Silicone is non-stick, so sticky concentrates release easily, which makes it popular for personal use. But silicone containers usually don't seal airtight and can pick up lint, so they're better for short-term handling than for retail or long-term storage.
Plastic Containers
Plastic is light and inexpensive, but some plastics can interact with oils and terpenes over time and may not seal as reliably as glass. If you use plastic, use it for short-term storage and choose containers made for concentrates.
Parchment and Extract Envelopes
Shatter and other glassy concentrates are often sold flat in parchment inside an extract envelope. The format keeps slabs flat and easy to break. For longer storage, keep the envelope in an airtight outer package.
Syringes
Distillate and other thick oils dispense best from 1mL glass applicator syringes, which make precise portions easy and keep the oil sealed between uses.
Vape Cartridges
For vape oil, 510-thread ceramic cartridges are both the container and the delivery device.
| Material | Airtight | Non-stick | Best for |
|---|---|---|---|
| Glass jar | Yes, with a good lid | No | Retail, long-term storage, most concentrates |
| Silicone | Usually not | Yes | Personal, short-term use |
| Plastic | Varies | Somewhat | Short-term, budget use |
| Parchment and envelope | No (needs an outer seal) | Yes | Shatter and slabs |
| Glass syringe | Yes | N/A | Distillate and oils |
Why Airtight Packaging Matters for Concentrates
Terpenes are the most fragile part of a concentrate. They're what give live resin and sauce their flavor, and they evaporate quickly in open air. An airtight container slows that loss, keeps texture stable, and contains odor. It also keeps out dust and moisture. Pair an airtight jar with storage in a cool, dark place, and most concentrates keep their quality much longer.

Sustainable Concentrate Packaging Options
- Choose reusable glass. Glass jars are durable, easy to clean, and often reused by customers, unlike most single-use plastic.
- Right-size every container. A 5mL jar for a gram uses less material than an oversized container.
- Use paperboard outer packaging. Concentrate jar boxes add branding and protection in a paper-based format that's widely recyclable where facilities accept it.
- Skip unnecessary layers. Each extra bag or insert adds waste. Use what protects the product and meets your state's rules, and nothing more.
Frequently Asked Questions
What is the best container for storing dabs?
An airtight, child-resistant glass jar, kept somewhere cool and dark. Use silicone only for short-term personal handling.
Can you store concentrates in the fridge?
For long-term storage, a sealed jar in the fridge can slow degradation. Let the jar reach room temperature before opening so condensation doesn't form on the product. For everyday use, a cool, dark cabinet works well.
Why did my shatter turn into sugar?
Shatter can "sugar" or crystallize with heat, agitation, and air exposure. An airtight container and cool storage help prevent it.
Which concentrate needs which package?
