Banner Material - The Big Picture - CPH Group Australia
We take a look at the different types of Banner Material, how each is made and the benefits they provide for super-sized signage and display applications.
Laminated vs Coated
There are two different ways to produce banner material:
- Laminated, where the PVC is laminated to the backing
- Coated, where the backing is dipped through the melted PVC
Laminated Banner is the cheaper of the two options to produce. This is because the backing and the PVC begin the production process as separate ready-made components and are then run through a laminator to adhere the two parts together.
A laminated face stock would be selected for its elevated print properties and include UV additives to enhance resistance and prolong yellowing.
Coated Banner is a more expensive process and produces a higher premium product. This is because during production the PVC needs to be kept in a molten state, the backing is then run through the melted PVC.
As the Banner dries it dries as an integrated piece rather than two pieces laminated together, as per the previous method, which can be pulled apart. Again, as with laminated Banner, UV additives are key to extend durability.
Plenty of options
Either type of Banner is suitable for specific applications, it really depends on the input components, the overall thickness, whether a single- or double-sided product, where it is to be used and ultimately the required life-span.
There are a number of variables … You’ll find that a double-sided will obviously be thicker, but depending on the application, say hanging indoors in a highly lit environment, the addition of a thicker black mesh centre layer is necessary to combat show-through. Think large format hanging ceiling banners in a shopping centre.
The bottom line is, the more components and the more refined the product is, the more your will outlay for the material. Overall, Banner is typically cheaper than using SAV for these larger format applications.
Weight isn’t everything
The thickness of the mesh component is measured in denier. A denier is a unit of measurement of linear mass density of fibres (the weight x number of fibres) this has some bearing on the final thickness. Again, the denier isn’t a critical factor as this can vary across applications.
A low denier count (less threads in the weave) may be used in a double-sided banner material to allow the PVC to penetrate and combine to achieve an extra smooth finish, as is the case with Neoflex USB (Ultra Smooth Blockout). While this product has a low denier (300x300) the result is an elevated surface due to the additional integrated PVC.
The variable here can be the tensile strength of the material used to create the mesh. So the denier rating does not necessarily align with the strength.
Lighter weight Banner tends to be used for shorter term applications, such as outdoor billboards and fence banners. Generally these tend to be laminated and are more economical, which is fortunate as the applications are often very large format or extended spans.
UV Upgrade
The inclusion of a UV Additive during production helps to slow down the process of deterioration in rugged Australian conditions. Without the UV additive, the banner would become brittle and start to tear or rip easier. The UV additive also acts to prevent premature yellowing under harsh sunlight.
Blockout
To achieve the blockout qualities generally the mesh component used is black. This is in line with common black/grey backing principals we all apply when reducing show-through and to achieve elevated blockout results.
