Pop Top Vials: The Complete Guide to 6, 13, 19, 30, 60 & 90 Dram Sizes

Quick Answer Pop top vials are one of the most widely used cannabis packaging formats, offering child-resistant protection in a convenient, easy-to-use container . Available in six standard dram sizes — 6, 13, 19, 30, 60, and 90 — these versatile vials accommodate everything from small samples to full ounces of flower. The 13 dram vial is the industry standard for 1g flower, while 30 dram is the workhorse for quarter-ounce packaging, and 90 dram handles full-ounce offerings . What Is a Pop Top Vial? A pop top vial is a child-resistant cannabis container with a built-in mechanism for opening and closing the lid . They feature an airtight, attached lid that "pops" open when pressure is applied to either side just below the cap . Key Features Child-Resistant Closure — The signature pop mechanism requires a specific two-action sequence that's difficult for young children to coordinate but intuitive for adults . These vials are certified under ASTM and CPSC standards. Airtight Seal — The design creates an airtight seal that locks in aromas and flavors, keeping cannabis fresh and potent . The self-sealing mechanism prevents oxygen from entering the bottle. Tamper-Evident — Shrink bands and tamper-evident seals can be applied to show if a package has been opened . Durable Construction — Made from shatter-proof polypropylene (PP) plastic that's lightweight and portable . Label-Friendly — The consistent shape and smooth surface make pop top vials ideal for automated labeling or direct printing . Opaque Options — Available in solid colors like black, white, green, and various opaque options to block UV light and meet state compliance requirements . The Dram Size System "Dram" is a unit of volume traditionally used in pharmacy and packaging . In cannabis packaging, dram sizes indicate how much product a container will typically hold. While actual capacity depends on flower density and product type, dram gives you a reliable way to match packaging to your menu . Why Dram Size Matters Cost per unit — Oversized containers mean you pay more for plastic and shipping  Presentation — A properly filled vial feels substantial; an oversized container looks half-empty  Compliance and labeling — Consistent sizes simplify label design, printing, and application  Storage and logistics — The right mix keeps shelving and inventory predictable  Complete Size Guide: 6 to 90 Dram 6 Dram Pop Top Vials — Micro Packs, Minis & Samples The 6 dram vial sits at the smallest end of the lineup, ideal for compact, controlled portions .

Specification Details Typical Capacity ~1.5–2g flower  Common Use Heavy grams, mini eighths, specialty SKUs  Best For Premium flower, eighths, extra headspace  Why Choose 19 Dram: Extra room for heavier grams that don't sit well in 13 dram  Great "differentiator size" for certain SKUs to stand out on the shelf  Premium feel with a slightly larger container 30 Dram Pop Top Vials — The Workhorse Quarter-Ounce Container When most people think about pop top vials, they're picturing a 30 dram . Specification Details Typical Capacity Up to ~7g (¼ oz) flower  Common Use Quarter-ounce SKUs, multi pre-roll packs  Best For Larger flower packs, pre-roll bundles, multi-pack items  Why Choose 30 Dram: Built for quarter-ounce offerings  Tall enough to feel substantial in hand and on shelf  Prime candidate for custom labels, tamper-evident bands, and seasonal branding  60 Dram Pop Top Vials — High-Capacity Half-Ounce Packaging 60 dram vials step up into the half-ounce space for value and bulk offerings . Specification Details Typical Capacity Up to ~14g (½ oz) flower  Common Use Half-ounce options, bundles, larger edible packs  Best For Larger flower portions, bulk product lines  Why Choose 60 Dram: Natural fit for "value" or "bulk" menu items  Larger footprint leaves plenty of room for compliance labels and warnings  Common for operations packaging both recreational and medical menus  90 Dram Pop Top Vials — Full Ounce, Bulk & Value Packs At the top end of the lineup, 90 dram vials are built for full-ounce SKUs and bulk offerings . Specification Details Typical Capacity Up to ~28g (1 oz) flower  Common Use Full-ounce SKUs, bulk pre-rolls, value packs  Best For Value packs, full-ounce style packaging, larger retail formats  Why Choose 90 Dram: Designed for full-ounce flower containers for value shoppers  Wider and shorter compared to other sizes  FDA-compliant materials with airtight, smell-proof seal  Quick Reference: Dram Size Selection Guide If You're Packaging Choose This Size Sample packs, mini pre-rolls 6 Dram Standard 1g flower 13 Dram Heavy grams, premium flower, mini eighths 19 Dram Quarter-ounce (7g) flower, pre-roll bundles 30 Dram Half-ounce (14g) flower, bulk packs 60 Dram Full ounce (28g) flower, value packs 90 Dram   Terpene Preservation: What the Research Shows A study conducted by eBottles and The Good Lab tested terpene preservation across various packaging types, including pop top vials . Key Findings Polypropylene pop top vials performed poorly in terpene preservation tests . All PP containers tested lost terpenes at a rapid rate The problem appears to lie with the closure seal — effective seals were not being made  Along with moisture loss, terpene loss was dramatic even over shorter test periods  Terpene Percentage Deviation from Mean : Container Type 8 Weeks 16 Weeks 24 Weeks Pop-Top (PP) -0.29 -0.37 -0.32 Push & Turn Vial (PP) -0.18 -0.40 -0.44 Calyx Polypropylene -0.38 -0.61 -0.56 Calyx Glass -0.24 -0.42 -0.49 What This Means for Brands Pop top vials with screw-cap closures and foil liners perform better for terpene preservation  PET plastic containers performed as well as glass in preserving terpenes  The closure seal is critical — not all pop top vials are equal  How to Use Pop Top Vials Packaging Pop top vials can be used to package various cannabis products : Loose flower — Fill halfway with buds and seal Pre-rolled joints — Place joint in vial and seal Edibles — Fill with gummies or candies and seal Concentrates — Fill with oil or wax and seal Sealing Heat Seal (Shrink Bands) — Shrink bands are plastic bands with perforations that seal pop top bottles . They provide a tamper-evident seal that shows if the package has been opened . Foil Liners — For better terpene preservation, consider using screw-cap closures with foil liners .
