Crash lock boxes are mostly used for shipping products that are manually packed at scale. They are one of the quickest and most efficient types of packaging to assemble.
Crash lock boxes are easily assembled in one quick action. Simply erect the flat box by pushing the two edges together. As you do this, the base will fold out and lock into place. You can then pack the box and use a peel & seal to seal it.
Based on internal testing, assembling a crash lock box is 40 to 50% faster than assembling a standard mailer box.
Yes! Our design team can work with you to design, ideate and prototype a bespoke solution. If you have any special requirements, such as waterproofing, please mention this in the inquiry form.
It depends on the material you choose, the size of your box, how it's packed and how it's been stored. Incorrect storage, for example, can lead to boxes becoming weaker over time. Fluting too will have an impact on the weight capacity. Typically, we don’t recommend sending anything heavier than 2kg in E-Flute, and anything heavier than 5kg in B-Flute.
If you have a specific weight requirement, please mention this in the inquiry form.
Yes. For the crash lock base to work, your box needs to have a minimum depth of 80mm. Anything smaller and the bases will not lock together correctly. If you want a box with a depth less than 80mm, we recommend a mailer box.
Store your boxes in a dry environment, away from possible sources of moisture like rain, leaks or areas of high humidity. You should also store them at a relatively constant temperature. Learn more
A peel & seal (a built-in self-adhesive strip) is the easiest and fastest way to seal a crash lock box.
Crash lock boxes are delivered flat, which is ideal for storage. They can then be easily assembled by hand.
Lead times vary based on the complexity of your design. Typically, crash lock boxes are designed, produced and delivered between two and four weeks.
MOQ stands for Minimum Order Quantity. The guideline MOQ for crash lock boxes is 3,000 units, but the exact MOQ will depend on the final approved dimensions of your packaging.
