Many friends engaged in packaging procurement and production often get stuck when choosing high-quality thick white cards. Both FBB yellow core white cards and SBS white core white cards can meet the basic requirements of packaging, but the performance differences directly determine the texture, durability, and even the procurement cost and order qualification rate of the packaging. Especially for gift boxes and color boxes that require a high-quality thick feel, choosing the right material can avoid subsequent rework and loss. Today, we will compare the core performance of both in detail to help you make an accurate selection.
Let's start with the performance that most people are concerned about - the high-quality thick performance. This is also a point that many purchasers prioritize. Under the same weight (such as 250g, 300g), FBB yellow core white cards have a very obvious advantage because it adopts a sandwich structure of "surface layer + yellow core + bottom layer", and the core layer is made of mechanical wood pulp. This material is inherently fluffy, so the thickness is 20%-30% higher than that of SBS white core white cards. The hand feel is more solid and the stiffness is better. After folding and forming, it is less likely to deform, even for large-sized folded color boxes, it can maintain a good shape and is not prone to softening.
Let's look at other core performances. Although SBS white core white cards have a slightly lower thickness, its advantage lies in "high-end and stable". It is made of fully bleached sulfite wood pulp, with a three-layer structure that is pure white throughout, without any impurities or flaws. The whiteness can be stable at 88+, the paper surface is smooth and flat, and the ink adhesion is extremely strong. Whether it is high-speed printing or fine hot stamping, UV glossing, embossing, etc., it can perfectly adapt and will not have ink loss or smudging. Moreover, its tear resistance, moisture resistance, and durability are better than FBB yellow core white cards. It will not change color or deform over time and complies with FDA food contact standards and EU environmental certification, suitable for export orders.
In contrast, FBB yellow core white cards, apart from high-quality thick and high stiffness, the biggest advantage is its high cost performance. The price is 15%-25% lower than SBS white core white cards, suitable for regular large-scale production orders. However, its shortcomings are also obvious. The cut surface is naturally yellow, not very refined, the whiteness and smoothness are not as good as SBS, moisture resistance is average, and it is prone to softening and discoloration in a humid environment. Moreover, it has a low adaptability to fine printing and complex post-processing techniques, and is prone to problems such as uneven hot stamping and poor ink coloration.
In summary, the performance differences between the two are as follows: if you want high-quality thick and high stiffness, choose FBB yellow core white cards; if you value printing texture, moisture resistance, and need to adapt to high-end scenarios or export orders, choose SBS white core white cards. Based on the weight requirements and process requirements of your products, you can select the appropriate high-quality thick white card.
