FAQ

 

Q: What is duplex cardboard?

A: Duplex Board is a kind of paperboard or cardboard, also named greyboard, due to its double side grey color. It consists of two layers, or plies, so people call it duplex board. The exterior one side of the board often is coated with a bright white appearance to give it a glossy sheen.

Q: What are the three types of cardboard?

A: Single face
Single wall
Double wall
Triple wall

Q: What holds cardboard together the best?

A: PVA Glue – Also known as white glue, PVA is one of the most commonly used adhesives for cardboard. It's easy to apply, dries clear, and is non-toxic, making it a great option for general use. Hot Melt Glue – Perfect for quick bonding, hot melt glue is ideal for corrugated or regular cardboard.

Q: What is the difference between B Flute and C flute cardboard?

A: B flute and C flute are two common types of corrugated cardboard used for packaging. C flute offers better stacking strength and cushioning, making it suitable for shipping boxes, while B flute is preferred for smaller products, printing, and die-cutting due to its good printability and puncture resistance.

Q: How to tell if cardboard is corrugated?

A: Corrugated is made up of multiple alternating layers: one or more flat layers (linerboard) and a wavy layer (fluting) making it thicker than cardboard. The fluted layer strengthens the board and helps to better protect the box's contents.

Q: Is cardboard a composite material?

A: Yes, cardboard, particularly corrugated cardboard, is a composite material. It's made by combining multiple layers of paper, with a fluted or corrugated layer sandwiched between flat linerboards. This layered construction gives cardboard its strength and rigidity while remaining relatively lightweight.
