GC1 White Back Paperboard - Premium for Packaging and Print
White back paperboard is a high-quality packaging and printing material distinguished by its white reverse side. The GC1 (or GZ1) designation indicates the highest grade of white back paperboard, manufactured from virgin fibre pulp. At Netuno, you will find white back paperboard in 210 g, 230 g, 300 g, and 400 g paper weights, available in both sheet formats and A4 packs.
What Is GC1 White Back Paperboard?
GC1 white back paperboard is a multilayer paperboard material with both the front and reverse sides finished in white. Depending on the manufacturer and product grade, the core of the board may be white or cream-coloured. The white reverse distinguishes this paperboard from the more economical grey back paperboard (GD2).
The GC1 designation refers to Folding Box Board (FBB) and identifies a premium white back paperboard manufactured exclusively from virgin fibre pulp, without any recycled fibre content. It is the highest grade of this type of paperboard, offering outstanding visual appearance and excellent mechanical properties.
GC1 white back paperboard is a coated material with a smooth coated surface on the front, designed for both offset and digital printing. The coating provides excellent colour reproduction and sharp detail.
White Back Paperboard - Benefits of the White Reverse
The white reverse side of white back paperboard has important practical and aesthetic advantages.
Packaging aesthetics - packaging made from white back paperboard also looks elegant on the inside. This is particularly important for packaging opened by the customer, such as boxes for cosmetics, electronics, and premium products.
Double-sided printing - white back paperboard can be printed on both sides. Although the reverse side is uncoated, it accepts printing and allows information to be placed inside the packaging.
Hygiene - a white reverse is perceived as more hygienic, which is important for food and pharmaceutical packaging.
Colour neutrality - white does not affect the perceived colour of the product inside the packaging, unlike a grey reverse.
