If you are involved in paper products (used for packaging, handicrafts making or printing), then you have probably seen double-sided black cardstock, but many people confuse it with single-sided cardstock. Unlike single-sided cardstock (with a plain color on the back), double-sided black cardstock has a uniform and high-quality black coating on both sides, making it suitable for countless projects and with wide applications. This guide will introduce the relevant content - what it is, its advantages, usage, how to choose, and the way to provide high-quality products for European and American buyers: Song Hong Industry.
What is double-sided black cardstock?
Double-sided black cardstock is a thick and durable paper, with both sides being uniform black, without fading spots or dark tones, unlike cheap substitutes. Measured by grammage (thickness), its range is between 250 and 400 grams per square meter: the grammage for invitations/tags is lower, while for sturdy packaging it is higher. High-quality products can guarantee the consistency of color and durability, even for large orders.
Main advantages (compared to single-sided)
Double-sided black cardstock has three significant advantages over single-sided cardstock:
- No hidden flat surface layer - you can freely utilize both surfaces to make visible items such as gift boxes or invitations.
Uniform and professional appearance - this is crucial for luxury packaging and brand materials.
- Environmentally friendly standards: recyclable and compliant with relevant standards in Europe/USA (RoHS, EN71, SGS).

Common uses
It is suitable for various enterprises worldwide:
Luxury packaging (cosmetics packaging, jewelry packaging, gift boxes) aimed at enhancing brand image.
Invitations and letter papers for creating a refined atmosphere (including wedding invitations, business cards) are available for selection.
- Products and printing (such as handmade photo albums, custom labels) benefit from its durability and printability.
How to choose the right one
To avoid choosing low-quality products, focus on the following aspects: GSM (usually 250 to 400gsm), color consistency, surface treatment (matte/ glossy/textured), and printing performance (to ensure clear, stain-free results).
