Child safety isn’t optional—it’s the law. And in packaging, it starts with the cap.

Childproof caps, also known as child-resistant (CR) closures, are mandatory in many regulated industries. To be compliant, caps must pass specific safety tests defined by global standards such as ISO 8317 and ASTM D3475.

In this article, we’ll walk B2B packaging buyers through the must-know testing protocols, how to verify certification, and how PauPack helps brands stay compliant from prototype to production.

What Are Childproof Caps and Why Are They Legally Required?

Ingesting non-food products is a leading cause of accidental poisoning in children under five.

Childproof caps are engineered closures that prevent young children from easily opening containers that hold hazardous or sensitive products, such as medications, supplements, essential oils, and cleaning agents.

Key Reasons CR Caps Are Mandated

PauPack offers a wide range of CR closures for glass, plastic, and hybrid bottles that meet the required resistance and usability standards—so your packaging can pass both lab testing and real-world scrutiny.

Which International Standards Govern Child-Resistant Closure Testing?

If a supplier says “childproof,” it must mean something measurable.

The leading childproof testing standards include ISO 8317 and EN 862 (Europe), ASTM D3475 (U.S.), and CCCR-2001 (Canada). Each defines how CR caps should be tested using panels of children and adults.

Overview of CR Testing Standards

At PauPack, we follow ISO 8317 as our baseline standard, ensuring CR mechanisms are tested and validated by internationally recognized labs for both safety and usability.

How Are Childproof Caps Tested and Certified?

It’s not enough to be “hard to open”—certification requires rigorous testing by panels of real children and adults.

Childproof caps are tested by evaluating whether 80–85% of children (ages 42–51 months) cannot open them within a defined time, while at least 90% of adults can open and properly close them.

Testing Process Breakdown

PauPack works with certified testing agencies (SGS, Intertek) to deliver lab-tested, certificate-backed CR closures for all bottle types and sizes.

What Packaging Buyers Must Verify Before Mass Procurement?

Don’t rely on verbal claims or vague sales terms. Compliance must be proven with documentation.

Packaging buyers should always request third-party testing reports, full ISO/ASTM certificates, and physical samples to confirm a cap’s CR status before placing wholesale orders.

CR Buyer Verification Checklist

At PauPack, we provide complete compliance kits for each CR bottle project—including digital documentation, stress test data, and compatibility records with specific bottles.

What Should B2B Buyers Ask Before Choosing Childproof Closures?

Not all “childproof” claims are backed by data. As a buyer, you need more than marketing language.

B2B packaging buyers should verify third-party certification, request actual test reports, check closure compatibility with their bottle, and ask about adult accessibility before placing a CR order.

Key Questions to Ask Suppliers

At PauPack, we provide full CR test data, compatibility checks, and custom cap pairing with each bottle SKU, helping buyers avoid fitment or compliance issues.

Are “Child-Resistant” and “Tamper-Evident” the Same Thing?

These terms are often confused—but they serve very different functions.

No, child-resistant (CR) and tamper-evident (TE) packaging are not the same. CR prevents access by children; TE shows if a product has been opened or compromised.

CR vs. TE at a Glance

At PauPack, many of our CR caps include optional TE features (e.g. break ring or liner seal), so clients can meet both safety and security goals in a single closure.

How Can Packaging Teams Integrate CR Testing into the Supply Chain?

Late-stage compliance testing can derail a launch. Smart teams build it in early.

Packaging teams should integrate CR testing at the prototyping phase and align with certified labs during pre-production to ensure compliant outcomes without costly revisions.

Best Practices for CR Integration

1. Choose pre-certified closures early in the design phase.

2. Request child/adult test data during supplier evaluation.

3. Test bottle + cap as a set—not in isolation.

4. Build in time for re-testing if you change decoration or cap mechanics.

5. Use CR sampling as part of QA/QC sign-off before production.

At PauPack, we run in-house torque + stress testing before sending samples to third-party labs, reducing the risk of failure and accelerating certification for your full package set.

What Role Does Adult Usability Play in CR Certification?

Safety isn’t just about keeping kids out—it’s about letting adults in.

CR caps must pass not only the “child panel” test (where kids fail to open the cap) but also the “adult panel” test, which ensures adults can open and close the container effectively.

Adult Usability in Certification

CR packaging that’s too difficult for adults to use can trigger complaints, returns, or even lawsuits—especially in pharma, where users may be elderly or have limited dexterity. PauPack’s CR designs are tested for both resistance and usability, ensuring legal and consumer-friendly results.
