FAQ
Q1: What is the difference between single-wall and double-wall corrugated?
A: Single-wall has one flute between two liners; double-wall adds a second flute and liner for higher crush resistance and a backup layer.
Q2: When is double-wall needed?
A: For heavy products, tall stacks, and rough transit where single-wall would crush.
Q3: Is double-wall always better?
A: No — it costs more, weighs more, and wastes strength on light products.
