Although their names may appear similar, white cardboard and white kraft cardboard are not the same. Below is a detailed comparison of these two materials.
**White Cardboard**
White cardboard refers to single or multi-layered paper entirely made from bleached chemical pulp with full sizing. This type of paper exhibits high smoothness, excellent stiffness, a clean appearance, and remarkable uniformity. It is widely used for producing business cards, packaging materials, invitations, and other printed items.
This material has one smooth side intended for printing and a slightly thicker side on the opposite face. The smooth surface ensures high-quality print results. White cardboard is commonly utilized in various applications, including the packaging boxes of small supermarket items, business cards, postcards, invitations, certificates, and decorative packaging materials.
**White Kraft Cardboard**
White kraft cardboard consists of bleached wood pulp on its outer layer, while the inner layers may be composed of natural or dyed wood pulp. Variants include Russian white card, Swedish white card, Finnish white card, as well as coated white board paper (with either a white or gray base). This material is extensively employed in baking food packaging, pharmaceutical packaging, anti-freezing and moisture-proof cartons, seafood packaging, handbags, cardboard cartons, electronic product packaging, color boxes, paper boxes, wine boxes, cigarette boxes, high-end packaging printing, and various other paper product packaging solutions.
There are two primary types of white kraft cardboard: bleached wood pulp-coated kraft paper and surface-coated kraft paper, both predominantly used for carton packaging. In the domestic market, unless otherwise specified, white-faced kraft cardboard typically refers to boxboard paper coated with bleached wood pulp. However, there are notable differences compared to international standards. Domestically, the surface layer uses bleached wood pulp, the lining layer employs deinked pulp or recycled white edges, and the core bottom layer utilizes either domestic or imported waste paper. Consequently, the quality of domestically produced white-faced kraft cardboard is generally inferior to that of imported varieties.
The most apparent visual distinction between white cardstock and white-faced kraft cardboard lies in their surfaces: white cardstock has uniformly white sides, whereas white-faced kraft cardboard features one white side and one yellowish side. Additionally, significant differences exist in their respective application domains, as outlined above.
