Custom Corrugated Boxes
Corrugated boxes are sturdy packaging designed to protect fragile or valuable products. The strength of corrugated packaging comes from its wavy design, as well as its thickness (technically known as flute).

What is a Corrugated Box?
In simple terms, corrugated boxes differ from other boxes because of their “wavy” and thicker walls. Corrugation is obtained through gluing three different layers together. The two outer sheets are flat and the sheet in the middle has a curly shape. The process of adding corrugation and thickness to the boxes is technically known as flute packaging.


How Much Weight Can a Corrugated Box Hold?
Corrugated boxes can on average withstand between 40lb (18kg) to 80 lb (36kg) for single-walled cartons, and up to 140lb (64kg) for double-walled boxes. The technical method to measure this is called Edge Crush Test (ECT). ECT can be defined as a test performed in a laboratory which applies pressure on corrugated cardboard to measure its crushing point. Most corrugated boxes will display an ECT score which indicates how much they can safely carry.
