A Practical Guide to Packaging Design
Have You Ever Bought a Product and Struggled to Open Its Packaging?
Too strong adhesive, a complicated closure, or on the contrary—a package that opened by itself during transport? If opening a package isn’t smooth and convenient, it can impact the customer’s experience and even the perceived value of the product. Choosing the right locking mechanism is just as important—it must protect the product while remaining easy to use.
But which closure suits your product best? And how do you choose a solution that meets both practical and aesthetic needs?
Read on to discover which opening and locking mechanisms are best suited for different types of carton and corrugated packaging.
Different Opening and Locking Mechanisms
Packaging design isn’t just about appearance—it’s also about functionality. The right opening and locking mechanism depends on the nature of the product, the target audience, and the sales channel (retail vs. e-commerce). Here are some of the most commonly used solutions:
1. Tuck Lock – Simple and Universal
- No glue required, making it easy to assemble
- Ideal for smaller and lighter products
This mechanism is especially popular for smaller products such as cosmetics and food packaging. It is also suitable for e-commerce, as it can be opened and closed multiple times without damaging the packaging.
2. Crash Lock Bottom – Fast and Durable
- The bottom locks automatically when the box is folded
- Suitable for heavier products, as it provides a stronger structure
This mechanism is preferred by retailers who need sturdy packaging that remains securely closed during transportation.
3. Snap Lock – Secure and Lightweight
- No glue required, but flaps must be folded under each other to close
- Suitable for medium-sized and lightweight product packaging
Snap Lock offers a good balance between simplicity and durability—it is easy to open while staying securely closed. It is commonly used for food and gift packaging.
What to Consider When Choosing Packaging?
Think about your target audience – Is the product being opened by a child, an adult, or an elderly person? Different groups require different levels of usability.
Consider security – If the product is sold in retail, the packaging must be strong enough to prevent accidental opening and theft.
Ensure durability – E-commerce packaging should be easy to open yet strong enough to protect the product during transport.
The choice of opening and locking mechanisms plays a key role in packaging production—it affects user experience, product safety, and even brand trustworthiness. The right solution depends on your product and its specific needs.
