If you sell THC or CBD products, the label on the box is not just decoration. It’s a legal document, a safety guide, and a silent sales pitch all in one. When the THC/CBD info is confusing, you lose trust, lose repeat orders, and sometimes even lose the whole batch in compliance checks.

At Zhibang, we see this every week when brands come to us with “rescue” projects: new SKUs, new states, urgent relabel. So let’s walk through how to show THC and CBD content clearly on your packaging, with real use scenes and practical tips you can plug into your next order.

THC and CBD labeling requirements on cannabis packaging

Show THC and CBD in mg per serving and per package

Most regulators and dispensary buyers want to see two things, very clear:

THC per serving (mg)
THC per package (mg)
Same for CBD

On your carton or tube, a simple, clean line works best:

THC: 10 mg per piece | 100 mg per box CBD: 5 mg per piece | 50 mg per box

You print this on the main facing panel, near the product name, not hidden on the bottom flap. Think of it like the “headline” for potency.

For a CBD oil SKU in a CBD oil cylinder tube box, that might look like:

30 ml bottle – 900 mg CBD total 1 ml serving – 30 mg CBD per serving

Even if your local law also wants percentage (%), keep mg as the hero unit. Shoppers think in mg, dispensary budtenders talk in mg, and your own sales reps do too.

Highlight legal THC limits for hemp and marijuana products

You also need to match your message to the product type:

Hemp CBD (with very low THC)
Marijuana products (THC dominant)
Balanced THC/CBD formulas

A simple sub-line under the potency data helps:

“Hemp-derived CBD formula, THC within legal limit for this market.”
“THC dominant edible – psychoactive product for adults only.”

You don’t need to write law numbers on the front, but you must show that you understand the limit story. When customs or platform QA check the box, they see you know what you are doing.

Designing readable THC/CBD packaging for busy shoppers

Font size, contrast and panel layout for potency info

In real life, your carton sits in a bright store, maybe behind glass, maybe in a crowded online thumbnail. The THC/CBD numbers must still pop out.

Basic “shop-floor” rules:

Use a font size at least as big as the net weight line
Keep strong contrast: dark text on light background or the opposite
Avoid thin script fonts for critical data
Leave enough white space around the potency block

Here’s a simple layout you can use for many SKUs (pre-rolls, vapes, edibles, tinctures, etc.):

Label Element	Suggested Position	Priority for Clarity
Product name	Top center of front panel	High
THC/CBD mg per serving	Directly under product name	Very high
THC/CBD mg per package	Same block, second line	Very high
Serving size	Under potency block	High
Warning / age statement	Bottom of front or side panel	High
Batch ID + QR to COA	Side or back panel, near barcode	Medium

On a rigid drawer box for live resin or wax, like the ones in our concentrate packaging boxes range, we often place THC/CBD data on both the sleeve and the inner tray. That way, even if the budtender remove the tray, the numbers stay visible.

Using icons and THC symbols to avoid mix-ups

Numbers are not enough. People shop fast, and sometimes a grandma picks the wrong box. Icons help:

Universal THC or cannabis leaf symbol near the potency line
A simple “CBD” badge for wellness products
Color coding (for example, green for CBD-heavy, red or orange for strong THC)

On a magnetic rigid gift box for a 3-jar CBD oil set, we often design three small circles on the lid:

Jar A – Balance (1:1)
Jar B – Relax (CBD high)
Jar C – Night (THC high)

Each circle shows mg per serving, so the end user can “read” the set in two seconds. This kind of visual system reduces wrong usage and customer support tickets.

Child-resistant packaging and compliance for THC products

THC/CBD labeling tied to child-resistant packaging requirements

If your product is psychoactive, child-resistant (CR) is not optional. Retail buyers now ask straight away:

“Is this box CR certified, and is the THC label cleaned up already?”

This is where your packaging, your THC/CBD data and your CR structure must work as one system. For example:

A child-resistant packaging drawer box for pods has a “push and pull” lock.
On the same panel, you show “Child-resistant, adult use only, contains THC” right next to the mg data.

You can add a short “how-to-open” pictogram set to avoid angry customers who think the box is broken. Sounds small, but it cut down returns and bad reviews.

Linking THC/CBD labels with batch ID and COA QR codes

Compliance teams love traceability. You tie your potency numbers to real lab data by:

Printing a batch or lot ID near the THC line
Adding a QR code that takes users to the COA (certificate of analysis)
Showing test date and lab name on the back or side panel

On a 30 ml CBD oil dropper bottle gift box, a typical back panel block might look like:

Batch: 2025-04-THC-07 Tested: 2025-04-16 Scan QR for full cannabinoid profile and safety tests

This is standard “black room” talk in QA: if the batch ID on the COA and the box always match, you pass audit faster and you sleep better.

Real usage scenes: different THC/CBD products, different labeling logics

THC edibles and gummies in rigid paper gift boxes

For edibles, users often eat “just one more” because the taste is nice. So your THC/CBD label must control that urge a bit.

A good pattern on a premium marijuana packaging gift box for gummies:

Front: “10 mg THC per gummy | 100 mg THC per box”
Side: “Serving size: 1 gummy. Wait at least 2 hours before another serving.”
Extra: Strong “NOT CANDY – ADULT USE ONLY” near the THC block

You don’t scare customers. You just talk straight, like a friend that already did the mistake once.

Pre-roll multipacks and blunt boxes

In pre-roll projects, a big pain point is mixed strength inside one box. Maybe five sticks, two different strains.

On a pre-roll boxes set with five joints, you can:

Print THC/CBD per joint on the inner tray next to each slot
Repeat a small potency table on the back of the outer sleeve

Small example table that can go on the back:

| Pre-roll No. | Strain Type | THC (mg per stick) | CBD (mg per stick) | | | — | | | | #1 | Sativa | 18 mg | 1 mg | | #2 | Indica | 20 mg | 0 mg | | #3 | Hybrid | 16 mg | 2 mg | | #4 | Hybrid | 14 mg | 3 mg | | #5 | CBD heavy | 5 mg | 15 mg |

Numbers here are sample only, but this kind of layout gives users a “menu card” feeling. They will share it on social and remember your brand.

CBD oils, tinctures and wellness sets

For CBD-first products, people care about calm, sleep, skin, and daily routine. They also worry about “Will I get high?”

On CBD lines, we like to:

Put “CBD mg per serving” and “Total CBD in bottle” large
Add a small line “THC below legal limit, non-intoxicating formula”
Show usage scene on the side: “Nighttime routine”, “Pre-workout”, etc.

A multi-SKU wellness range in child-resistant cannabis pre-roll and edibles boxes or CBD tubes can share a common label system. That makes life easier for your design agency and keeps your shelf look tight.

How Zhibang helps you implement clear THC/CBD labels

Custom marijuana packaging solutions for different SKUs

As a China printing factory focused on OEM/ODM and bulk orders, Zhibang works with brand owners, cross-border sellers, wholesalers, design studios and sourcing teams who juggle many SKUs and many markets at the same time.

For THC/CBD projects we often combine:

Custom rigid drawer or clamshell boxes for concentrates and vapes, from our cannabis concentrate packaging line
Child-resistant paper tubes and slider boxes for cartridges and pods from our user-friendly child-resistant range
Premium CBD oil sets in magnetic CBD gift boxes

We build the dieline with enough “real estate” for your THC/CBD data, warnings, barcodes, platform labels, and QR codes. That way you don’t end up with crowded artwork that nobody can read.

If you also run cosmetics, food, or gift packaging lines, you can keep one trusted partner for everything: Zhibang Packaging. Our team helps you sync your cannabis and non-cannabis packaging style, so your brand feels like one family across paper gift boxes, apparel boxes, candle boxes or jewelry boxes.

In the end, clear THC/CBD labeling is not only “compliance cost”. It cuts repacks, avoids listings being taken down, and makes shoppers trust your brand faster. You sell more, you waste less, and your packaging team stop firefighting every new SKU. That is the kind of quiet value we like to build into every box that leaves Zhibang’s line.
