Child Resistant Packaging Explained: Complete Guide for Cannabis Brands

Quick Answer

Child-resistant packaging (CRP) is packaging designed to be difficult for children under five years of age to open, while remaining accessible to adults. In the cannabis industry, CRP is mandatory across all regulated markets and must meet federal standards under the Poison Prevention Packaging Act (PPPA) and ASTM D3475 testing protocols. There are two main types: Single-use CRP (opens once, then no longer child-resistant) and Multi-use/Lifetime CRP (remains child-resistant through repeated openings). Compliance isn't optional — it's the responsibility of the licensee that packaged the cannabis good to ensure every package meets CRP requirements .

What Is Child Resistant Packaging?

Child-resistant packaging (CRP) is a specialized packaging category designed to prevent children from accessing potentially harmful contents. In the cannabis industry, it's a legal requirement, not a design preference.

The Core Principle

The fundamental concept behind child-resistant packaging is simple but scientifically rigorous:

• Children under 5 years old must not be able to open the package within a reasonable time

• Adults (including seniors with reduced dexterity) must be able to open and properly close it

This balance is achieved through mechanical mechanisms that require specific actions — squeezing, pushing, twisting, or combinations thereof — that young children typically cannot coordinate or apply sufficient force to perform.

The "Child-Resistant" vs "Child-Proof" Distinction

It's important to understand that no packaging is truly "child-proof." The legal standard is "child-resistant" — meaning it significantly reduces the risk but doesn't eliminate it entirely. Even properly certified packaging can be opened by some children, which is why responsible storage remains essential.

Why Child Resistant Packaging Matters

Legal Compliance

Every regulated cannabis market requires child-resistant packaging. State laws, built on federal standards, mandate that:

• All cannabis goods must be sold in child-resistant packaging 

• The licensee that packaged the product is responsible for ensuring CRP compliance 

• Packaging must meet PPPA standards (16 CFR 1700.15 and 16 CFR 1700.20) 

Safety and Responsibility

Beyond legal requirements, CRP protects:

• Children from accidental ingestion of cannabis products, especially edibles which can be mistaken for regular candy or snacks

• Brands from liability and reputational damage

• The industry from negative publicity and increased regulation

Consumer Trust

Properly designed CRP signals professionalism and responsibility. When consumers see compliant packaging, they trust that the brand prioritizes safety and follows regulations — factors that influence purchasing decisions.

The Regulatory Framework: PPPA & ASTM D3475

The Poison Prevention Packaging Act (PPPA)

The PPPA (16 CFR 1700.15 and 1700.20) establishes the federal standard for child-resistant packaging in the United States . Under this framework:

• Packaging must be tested with children aged 42–51 months

• At least 80% of children must not be able to open the package within 5 minutes

• At least 90% of adults must be able to open and properly reclose the package 

Key PPPA Requirements:

• Testing must use standardized protocols with children grouped by specific age ranges (30% aged 42–44 months, 40% aged 45–48 months, 30% aged 49–51 months) 

• Adult testing includes both younger and senior adults 

• Certification documentation must be maintained by the manufacturer and licensee 

ASTM D3475 Standard

ASTM D3475 is the specific testing standard used to verify child-resistance . It outlines:

Child Testing Protocol:

• Groups of 50 children tested in familiar environments

• Children given simple instruction: "Please try to open this for me"

• 5-minute and 10-minute testing periods

• Openings using teeth or other methods are recorded

• Failure defined as any child opening the package 

Adult Testing Protocol:

• Adults tested separately (not in groups)

• Provided with printed instructions (as the consumer would receive)

• Must open and properly reclose the package 

• 5-minute testing period for opening, 1-minute for reclosure 

Testing Documentation Requirements:

• Color photograph of the packaging showing closure

• Product name, size, and specifications

• Closure manufacturer and material details

• Complete test results with laboratory information 

Types of Child Resistant Packaging

Single-Use CRP (Initial CRP)

Single-use CRP is child-resistant only until first opening. Once opened, it cannot be reclosed in a child-resistant manner.

Key Characteristics:

• Provides child-resistance for the initial opening only

• Must be labeled: "This package is not child-resistant after opening" 

• Typically uses heat-sealed plastic (4 mils minimum thickness) without easy-open tabs, dimples, corners, or flaps 

Common Applications:

• Cannabis flower

• Pre-rolls

• Topicals

• Concentrates (dab, shatter, wax)

• Vape cartridges 

Single-Use CRP Exemption:
A bottle sealed with a pry-off metal crown cork-style bottle cap qualifies as single-use CRP if it contains only one serving .

Multi-Use / Lifetime CRP

Multi-use CRP maintains its child-resistant properties throughout the product's lifecycle. It can be opened and closed repeatedly while remaining compliant.

Key Characteristics:

• Remains child-resistant after each reclosure

• No special label requirement

• Typically uses mechanical mechanisms (press-and-turn, squeeze-and-pull)

Common Applications:

• Edibles (must be lifetime CRP) 

• Orally-consumed concentrates (tinctures, capsules)

• Suppositories

• Any product containing more than a single serving that isn't individually wrapped in CRP 

Child Resistant Packaging Formats: Your Product Categories

Pouch Containers

Mylar bags and pouches can be made child-resistant through specialized zipper mechanisms.

How It Works:

• Child-resistant zippers require a specific action (squeeze and slide, press and pull) that young children typically can't coordinate 

• Heat-sealable options provide tamper evidence and single-use CRP

Your Products:

• Dual Compartment Pouch Containers — Can use CR zippers on both compartments; ideal for separating different products or doses

Best For:

• Single-use applications (flower, pre-rolls, edibles) when heat-sealed 

• Multi-use applications with CR zipper mechanisms

Compliance Note: Plastic packaging that is at least 4 mils thick and heat-sealed without an easy-open tab qualifies as single-use CRP .

Spiral Products

Spiral packaging uses specialized child-resistant closures that combine multiple actions.

How It Works:

• Most child-resistant caps require a "push-down-and-turn" or "squeeze-and-turn" action

• These mechanisms are designed to be difficult for young children to perform but intuitive for adults 

Your Products:

• Spiral Tubes — CR caps protect pre-rolls and small products

• Spiral Bottles — Press-and-turn CR closures

• Spiral XL Containers — Larger format with CR mechanism

Opening Instructions for Pop-Top Tubes:

1. Locate the indentation or tab on the side of the lid 

2. Squeeze the sides at the indentation 

3. Apply firm, quick pressure — the top should "pop" open 

4. Use both hands if needed (one to squeeze, one to lift) 

Paper & Cones

Paper and cone packaging presents unique challenges for child-resistance.

How It Works:

• Cones must be packaged inside CR-compliant containers (typically tubes)

• Single-use CRP with heat-sealed overwrap is common

Your Products:

• Paper Cones — Must be packaged in CR containers

• Pre-Rolled Cones — Pre-packaged in CR tubes

• Cone Sleeves — May be used as secondary packaging

Compliance Note: Secondary packaging doesn't need to be CR if the primary packaging is CR.

Compliance Requirements by Product Type

Single-Use CRP Required

• Cannabis Flower — Can use heat-sealed mylar bags (4 mil minimum thickness) 

• Pre-Rolls — Pop-top tubes or heat-sealed pouches 

• Topicals — Single-use or multi-use depending on format 

• Concentrates (Dab, Shatter, Wax) — Typically single-use 

• Vape Cartridges — Single-use CRP 

Multi-Use / Lifetime CRP Required

• Edibles — Must maintain child-resistance after each opening 

• Tinctures — Multi-use with CR cap

• Capsules — Multi-use with CR closure

• Suppositories — Multi-use CRP

Testing & Certification Process

Who Is Responsible?

The licensee who packaged the cannabis good is ultimately responsible for ensuring CRP compliance . However, testing and certification is typically performed by:

The Manufacturer: The entity manufacturing the packaging (or the US-based distributor/importer) must :

• Conduct or commission PPPA testing (16 CFR 1700.15 and 1700.20)

• Maintain testing documentation

• Certify that packaging meets child-resistant standards

• Provide certification to licensees

The Licensee: Must :

• Verify packaging certification

• Submit certification forms with packaging applications

• Maintain records demonstrating compliance

• Ensure packaging matches certified specifications

Certification Documentation Requirements

Licensee Form Must Include:

• Package size, material, and closure specifications

• Intended use date for the packaging

• Types of products being packaged

• Dosage or unit counts 

Manufacturer Form Must Include:

• Complete contact information

• Testing results from an accredited laboratory

• Photographs of the packaging

• Confirmation that tested packaging matches proposed packaging 

Key Requirement: All testing documentation must be unaltered and unredacted. The Division will not approve packaging applications with redacted testing documentation .

Common Compliance Mistakes

1. Assuming All Packaging Is CRP

Not all closures are child-resistant. Ask your supplier for PPPA certification proof .

2. Mixing CRP and Non-CRP in Same Package

If product is packaged in a non-CR container inside a CR box, the primary packaging must be CR.

3. Using Exit Packaging

Exit packaging (used at retail point-of-sale) is not required to be child-resistant and cannot satisfy CRP requirements .

4. Ignoring Labeling Requirements

Single-use CRP must be labeled: "This package is not child-resistant after opening" .

5. Failing to Document

Licenses must maintain testing documentation. If packaging is changed (size, material, closure), new certification may be needed .

FAQ

What is the difference between child-resistant and child-proof packaging?
Child-resistant means designed to be difficult for children under five to open, but not impossible. No packaging is truly child-proof. Child-resistant packaging must pass PPPA testing standards .

What packaging qualifies as child-resistant for cannabis?
Packages certified under PPPA (16 CFR 1700.15), bottles with pry-off metal crown caps containing only one serving, or heat-sealed plastic packaging at least 4 mils thick without easy-open features .

What is single-use vs multi-use CRP?
Single-use CRP is child-resistant only until first opening (must be labeled "This package is not child-resistant after opening"). Multi-use CRP remains child-resistant through repeated openings .

Do edibles require special CRP?
Yes, edibles must use multi-use/lifetime CRP that remains child-resistant after each opening .

How do I know if my packaging is child-resistant?
Ask your packaging supplier for PPPA certification documentation. The manufacturer should provide testing proof .

Who is responsible for CRP compliance?
The licensee that packaged the cannabis good is responsible for ensuring the package meets CRP requirements .

Can I use exit packaging for CRP?
