Double wall cardboard boxes are designed to increase protection with an extra layer of corrugated cardboard. These strong boxes are perfect for shipping delicate items including jewellery and trinkets, glassware, electrical goods and delicate clothing.
Incorporating an extra layer of fluted, corrugated cardboard offers excellent cushion protection against unwanted bumps and knocks. Double wall cardboard is bonded together to create a strong, robust material which is relied on by businesses and customers in any industry. All of this added strength means they’re ideal for storage too! Double wall cardboard boxes boast an improved weight capacity meaning heavier items can be stored and transported safety and over a longer time period.
The most common double wall flute profiles are:
7mm in thickness. Double wall material coupling two types of flute profile. The B and C flute together provide a good level of all round performance. This type of flute is most commonly used in shipping cases for higher levels of contents protection.
3.8mm – 4.1mm in thickness. Double wall material combining the fine E flute and the commonly used B flute. The results give an excellent performance level in both print finish and impact protection.
The quality and strength of the board lining papers are generally determined by the weight per square metre in Grams e.g. 125, and also content mix of new and recycled wood fibre Kraft paper (‘K’) being of better quality (higher content of new wood fibre) than Test paper (‘T’). For example: 125 K/T B would mean the weight of the paper used is 125 grams per square metre, the external paper being Kraft and the internal being Test quality with ‘B’ fluting between.
