The structural design of folding cardboard boxes must balance ease of transport, product stability, and user-friendly opening experience. Common types include:
1. Hook-and-loop bottom box: Automatically forms the box using a bottom-locking structure, reducing assembly time and suitable for mass production.
2. Double-slot box: Secures the box using side slots; simple structure and low cost, commonly used for lightweight product packaging.
3. Automatic bottom-locking box: Features a pre-folded bottom design; automatically forms the box upon unfolding, eliminating the need for additional adhesives and improving production efficiency.
4. Snap-on bottom box: Secured by bottom folding latches; stable structure, suitable for applications requiring high load-bearing capacity.
Thickness and weight can be customized according to product needs. For example, health supplement packaging typically uses 250-350g white cardboard to balance stiffness and cost.
