Types Of Paperboard

There are several types of paperboard in usage. A paperboard is a thick paper-based material. Although, there are no solid differences between the paper and paperboard, the paperboards are thicker than papers. More generally, the paperboards would be more than 0.25 millimeters thick. These paperboards could be single-ply or multi-ply. Usually, the paperboards could be cut and formed more easily and lightweight. Since these paperboards are generally strong, they are used for the purpose of packaging. Sometimes, these paperboards are also called as ‘cardboards’ which are the generic lay term that are used to represent any of the heavy paper pulp-based board.

The different types of paperboard are specially processed in order to get the better appeal and printability, to impart barrier properties, to protect, to provide rigidity and to meet the legal and health demands. Almost all types of paperboard are made from the renewable sources.

Most common types of paperboard are as follows:

White Lined Chip Board – Recycled Fiber:

These types of paperboard are the multi-layer boards that consist of 60 – 100% of the recycled fibers. The top layer of these boards are produced by using either high grade white pre-print waste paper or bleached chemical pulps. The middle and back layers would be made up from waste papers. The weight of these boards would range from 200 – 600 GSM. These types of paperboard are extremely smooth. These are the cost effective substrates for both the gravure and the offset printing processes. The surface brightness of the white lined chip board is supposed to vary from the percentage of 80 – 85% ISO. These types of paperboard are used more extensively in developed countries.

White Lined Chip Board – Uncoated Recycled:

These types of paperboard are made up of 20% virgin fibers on the top or from 100% waste paper without any sorts of coating. Generally, these boards would be laminated with many other different types of boards. The basis weight of the final boards of this kind would be more than 1000 GSM. The solid packaging boards of these kinds would be used for set-up boxes and many other packaging applications. These are also used as the packing dividers in the corrugated boxes and luggage manufacturing.

Virgin Fiber-based Board – Solid Bleached:

These are produced entirely of bleached chemical pulps. There are about 2 to 4 solid homogenous layers of fibers in these types of paperboard. They might use either long or short fibers. The surface would be double coated while the back would be left uncoated or lightly coated. The surface brightness of these boards would 90% ISO. The roughness of the top surface would be less than 1.2 microns PPS. More generally, these types of boards are superior when the purity of these is good. The solid bleached boards are more suitable for packaging aroma and flavor sensitive products.

Virgin Fiber-based Board – Folding box:

These types of paperboard consist of 3 layers where the top layer would be made of bleached chemical pulps. The back of these boards would be either manila or white in colors. The middle layer would contain mechanical pulps. Generally, the visual properties would be slightly inferior to that of the solid bleached boards.

In addition to the above mentioned types of paperboards, there are various other kinds in use at present.
