Paper board,this versatile and recyclable material can be seen in nearly every facet of our lives.
From packaging and distribution to the creation of displays and food containers, the average consumer would be left with few options if this substance was not available. Before we examine its durability, it is a good idea to take a closer look at what makes paperboard so very special.
From a very broad definition, paperboard generally consists of a certain number of papers which have been layered above one another. It is normally thicker than 0.30 millimetres and it is known for a superior sense of rigidity. However, it can also be creased and folded in order to accommodate a nearly limitless number of shapes and dimensions. Thinner configurations can be used as signage and sales materials. Thicker gray paperboard is more suitable for shipping and storage. Still, these are only a handful of uses.
The exact type of grey paper board will primarily depend upon the initial production processes. Thin versions can be made by pressing individual sections together through a process known as wet layer construction. Those which are required to be thicker (and therefore stronger) will often employ an adhesive known as polyvinyl acetate (PVA) between the individual layers. Other types may be provided with an exterior laminate; quite common when making packages or if marketing materials need to be produced. However, the real secret behind this magical substance involves its sheer durability.
The inherent strength associated with gray board is caused by the numerous layers of individual paper which are permanently bonded together. Any physical stresses that happen to be encountered will be spread out across these layers. So, each individual section is more resistant to tearing, warping and bending. This is even more relevant if the paperboard has been impregnated with PVA. Not only is paperboard durable, but it is extremely lightweight and resistant being pierced. Still, the benefits do not end here:
The material is somewhat flexible, so it can be used to suit nearly any packaging requirement.
Its surfaces will accept various types of printing.
Boxes and similar containers will retain their strength even if they are folded flat before construction.
