What is Carton Duplex and How is it Made?

Section 1: What is Carton Duplex?

Carton duplex, also known as carton duplex paper board, is a versatile packaging material that is commonly used in a wide range of industries. It is made from two layers of bleached chemical pulp, which provides strength and durability to the board. The two layers are tightly bonded together to create a solid and reliable material for packaging.

How is Carton Duplex Paper Board Made?

The process of manufacturing carton duplex paper board involves several steps. It starts with the selection of high-quality bleached chemical pulp, which is then processed to remove impurities and ensure a smooth texture.
