Wholesale Cannabis Packaging: How to Package for Bulk Sales and Repackaging

Written by Lia Thompson, packaging specialist at Creative Labz. Last updated October 3, 2026.

Product rarely moves from grower to customer in a single package. Flower leaves the farm in pound bags, gets split into ounces and eighths, and lands on a shelf in a jar or a branded bag. Concentrates arrive in bulk and leave in 5mL jars. Every one of those handoffs costs time, and your packaging decides whether that step takes minutes or an afternoon.

This guide covers how wholesale and bulk cannabis packaging works, which formats make repackaging faster, and how master boxes keep retail units organized from the back room to the sales counter.

What Makes Packaging Repackaging-Friendly?

Packaging built for bulk sales and repackaging tends to share five traits:

• Standard sizes that divide evenly. A 448g pound splits cleanly into 16 ounces (28g) or 128 eighths (3.5g). When bulk and retail packaging line up with standard weights, splitting a lot takes a scale and simple math, not guesswork.
• Closures that open and reseal easily. Bulk bags get opened, weighed from, and closed many times. A strong zipper means you aren't re-bagging the remainder every time you pull product.
• Barrier protection. Product can sit in bulk storage for weeks. Opaque, smell-resistant Mylar protects it from light and air and keeps odor in while it waits.
• Room for labels. Packaging that takes a strain, weight, or batch sticker lets one stock of bags or jars serve your whole menu.
• Cases that hold a set count. Master boxes with a fixed number of slots make counting, shipping, and invoicing faster.

Bulk Packaging Formats for Flower

Pound and Quarter-Pound Mylar Bags

448g (one pound) Mylar bags are the standard for moving flower in bulk. They're light, they store flat, and a resealable zipper lets you pull product without exposing the whole lot. For smaller wholesale orders, 112g quarter-pound bags fill the gap between bulk and retail.

Retail Sizes for Repackaging

Once bulk flower arrives, it gets split into retail units. The most common are 3.5g eighth bags and 28g ounce bags, along with child-resistant jars for premium eighths. Keeping retail stock in the same packaging family as your bulk bags makes it easier to track which units came from which lot. Every size is in our Mylar bag collection.

Bulk Packaging for Concentrates

Concentrates are repackaged by the gram, so the containers need to be precise, well sealed, and easy to fill. Most brands use child-resistant glass concentrate jars in 5mL or 7mL sizes for retail and larger 28g jars for bulk.

The step many brands skip is the outer box. Concentrate jar boxes are sized for 5mL and 7mL glass jars, so a filled jar drops straight into its box and is ready to sell. The box protects the glass in transit, adds space for branding, and comes in ready-made designs, so smaller brands get a finished look without a custom print run.

For bulk concentrate, a 16-count master box for 28g jars holds each jar upright in a fixed grid, which makes counting and shipping wholesale orders much faster. We cover it in Maximize Your Cannabis Business with Master Boxes for 28g Concentrate Jars.

Master Boxes: The Missing Piece in Wholesale Packaging

A master box (or master case) is an outer carton that holds a set number of retail units. It's how most wholesale orders get packed, counted, shipped, and displayed. Creative Labz carries master boxes for several product lines:

• Master boxes for concentrate jars, including a display box that holds 16 of our 28g glass jars
• 116mm doob tube display master boxes for single pre-rolls
• Pre-roll box master cases that hold 24 of our 109mm three-pack boxes

Master boxes save time in three places. Packing goes faster because staff fill a fixed grid instead of counting loose units. Receiving goes faster because the buyer counts cases instead of individual jars. And a display master box doubles as a ready-made counter display. For flower jars, see our guide to master boxes for 3.5g glass jars.

Labeling and Compliance When You Repackage

Every time product changes packages, it needs to be labeled again. Before you split a bulk lot, plan for:

• Strain and weight labels. Strain labels and weight stickers let one stock of blank packaging cover your whole menu.
• Tamper evidence. Tamper-evident stickers and shrink bands show buyers the unit hasn't been opened since it was packed.
• Child resistance and state rules. Packaging and labeling requirements vary by state and change often, so confirm your state's current rules before choosing retail packaging. Our overview of legal considerations for cannabis packaging and labeling is a good place to start.
• Batch tracking. Mark the source lot on every case. If a buyer has a question, you can trace it in seconds.

A Simple Repackaging Workflow

1. Stage your packaging first. Label retail bags or jars and set out master boxes before you open the bulk product, so it spends as little time exposed as possible.
2. Weigh on a calibrated scale. A 0.01g scale keeps every unit accurate, so you don't come up short or give product away.
3. Seal right away. Close zippers fully, and heat-seal retail bags above the zipper for tamper evidence. A hand-held Mylar bag heat sealer makes this quick.
4. Case and count. Load finished units into master boxes, mark the count and lot, and reseal what's left of the bulk bag.

Frequently Asked Questions

What size Mylar bag holds a pound of flower?

A 448g bag is sized for one pound. Flower density varies by strain and trim, so leave enough room to close the zipper without crushing buds.

What is a master box in cannabis packaging?

It's an outer case that holds a fixed number of retail units, such as 16 concentrate jars or 24 pre-roll boxes. Master boxes are used to pack, ship, count, and display wholesale orders.

Can I use white label packaging for wholesale?

Yes. White label packaging works well for wholesale because you can add your own labels to each order. Learn more in White Label Cannabis Packaging: What To Know.
