Product description

Product Overview

Japanese-style bottom boxes, also known as insert-bottom boxes, are engineered for enhanced load-bearing performance compared to standard base boxes. While the top opening structure remains similar to regular folding cartons, the bottom features a cross-locking insert design that utilizes the rigidity and tensile strength of paperboard to create a self-supporting base.

This structural innovation significantly improves weight distribution, prevents bottom collapse, and reduces the risk of product drop-out during handling, stacking, or transportation—making it an ideal solution for medium to heavy products requiring reliable packaging support.

FAQ – Japanese Insert-Bottom Boxes

Q1: How much weight can a Japanese-style bottom box support?
Load capacity depends on paper weight, box size, and lining design. Our engineering team customizes materials to match your product requirements.

Q2: Is assembly more complex than standard base boxes?
No. Assembly requires only two simple steps and is nearly as fast as standard folding cartons.

Q3: Can inner lining be added for extra support?
Yes. Custom inserts help distribute weight evenly and protect the product.

Q4: Are these boxes suitable for automated packing lines?
They are ideal for manual and semi-automated packaging. Full automation compatibility can be evaluated case-by-case.

Q5: Can these boxes replace rigid boxes for heavy items?
In many applications, Japanese-style bottom boxes offer a cost-effective alternative with sufficient strength, depending on product weight.
