Box Purchase Guide

HOME > Customize > Box Purchase Guide
It is not easy to choose the right box for your product.

We offer you a basic and effective guide for finding boxes that meet your requirements in product weight, mode of
shipment and distribution as well as your economy and more. For more information and customized design, please
call our customer service.

STEP 1. Measure size and weight of your products

Your product size shall correspond to inner dimensions of the box. Typically labelled box dimensions are of outer
measurements. Add the following values to the dimensions of your products.

A (SW) Flute = W 6mm, D 6mm, H 9mm
B (SW) Flute = W 4mm, D 4mm, H 6mm
E (SW) Flute = W 2mm, D 2mm, H 2mm
AB (DW) Flute = W 9mm, D 9mm, H 18mm
STEP 2. Select Corrugated Fiberboard

Select flute types - A flute (4.5~4.8mm), B flute (2.5~2.8mm), E flute (1.2~1.6mm) and AB flute (7.0~8.5mm)
- based on your products. For products over 10kg, select A to AB and B for anything lighter. (Buffer capacity against
impact increases as flute height increases). If you require more protection against impact for lighter goods, it is safer
to select double faced corrugated boxes such as AB flute. Boards of same height but varying flute distances and
liner materials will display vastly different strengths. For packing products that require extra caution, please call us
for consultation.

Please refer to the table below.
