How a “Childproof” Carton Works: Key Features and Design Innovations
Child-resistant packaging—commonly referred to as ‘childproof packaging’—plays a critical role in preventing accidental ingestion of hazardous substances by children. While no packaging can be truly childproof, Keystone’s innovative child-resistant cartons offer industry-leading protection while maintaining user accessibility and sustainability. In this article, we’ll explore how Keystone’s packaging solutions work and what makes them effective, compliant, and eco-conscious.
What Makes a Childproof Carton Effective?
Effective childproof cartons are engineered to be challenging for children to open, yet easy and intuitive for adults. Key design elements include:
- Specialized Locking Mechanisms – Multi-step actions like push-and-slide or pull-tab designs prevent access by young children.
- Reinforced Structural Integrity – Durable paperboard resists tearing, crushing, or puncturing.
- Precision-Engineered Friction Points – Slow down unauthorized access and reduce accidental openings.
All Keystone designs meet or exceed rigorous third-party testing standards set by agencies like the Consumer Product Safety Commission (CPSC), Food and Drug Administration (FDA), European Medicines Agency (EMA), and Health Canada. Keystone’s cartons proudly hold the F=1 child-resistance rating—the highest industry benchmark.
How Keystone Stands Apart: Safety with Sustainability
Keystone integrates sustainability into every childproof carton. Instead of relying on plastic locking parts, Keystone uses engineered paperboard structures that deliver both high-level child resistance and environmental benefits. This approach aligns with modern sustainability goals without sacrificing product safety.
