Many friends in packaging, printing, and gift box making often encounter a problem: the client asks for white cardstock, but they end up with gray back white cardstock, or they want to use coated paper for packaging boxes, only to find that it's too soft and prone to folding. In fact, white cardstock, coated paper, and gray back white cardstock look similar, but their uses, textures, and prices are quite different. Today, I'll explain it in plain language so that you'll never make a wrong choice again.
I. First, understand: What is white cardstock?
White cardstock is a type of cardstock that is white on both sides, thick and stiff, with a good texture and no obvious coating, not overly shiny.
Its characteristics are obvious:
Double-sided pure white, high flatness
Hard enough to be suitable for packaging that needs to stand up
Clear printing, no reflection, with a high-end and elegant texture
Commonly used for medicine boxes, cosmetic boxes, food card boxes, handbags, tags, etc.
Simply put: For scenarios that require stiffness, good texture, and clean double sides, white cardstock is the preferred choice.
II. Coated Paper: Looks shiny, but not suitable for hard packaging
Coated paper has a coating on its surface, which feels smooth and shiny, with very bright colors. The picture books, magazine covers, and promotional flyers we often see are mostly made of coated paper.
The biggest difference between it and white cardstock is:
Shiny surface, extremely high color reproduction
Thin and soft, poor stiffness, not suitable for load-bearing or three-dimensional packaging
Suitable for flat printing, picture books, posters, labels, but not for boxes
Many people mistake high-gloss white cardstock for coated paper, but they are completely different: coated paper is soft, while white cardstock is hard.
III. Gray Back White Cardstock: High cost performance, but "one side white, one side gray"
Gray back white cardstock, often called gray back white in the industry, is a type of cardstock that is white on the front and gray on the back.
Its characteristics are very practical:
Lower cost than white cardstock, high cost performance
Moderate hardness, suitable for ordinary packaging
Because the back is gray, it cannot be used for double-sided display
Commonly used for inner packaging of express boxes, ordinary product packaging boxes, takeout boxes, simple card boxes
If your product does not need double-sided display and you just want to control costs, gray back white cardstock is a very suitable choice.
IV. Core Differences Between White Cardstock, Coated Paper, and Gray Back White Cardstock
1. Appearance Differences
White cardstock: Double-sided pure white, no strong reflection, matte / slightly coated texture
Coated paper: High-gloss on one or both sides, very smooth, obvious reflection
Gray back white cardstock: White on the front, gray on the back, easily distinguishable
2. Hardness and Stiffness
White cardstock: High stiffness, good hardness, suitable for three-dimensional boxes
Coated paper: Soft, almost no resistance to folding
Gray back white cardstock: Moderate hardness, sufficient but not as good in texture as white cardstock
3. Applicable Scenarios
White cardstock: High-end gift boxes, food packaging, medicine boxes, handbags, double-sided printed products
Coated paper: Picture books, posters, promotional flyers, labels, magazines
Gray back white cardstock: Ordinary inner boxes, simple packaging, low-cost product boxes
4. Price Differences (from high to low)
White cardstock > Coated paper > Gray back white cardstock
V. How to Quickly Choose When Purchasing? Here's a Mnemonic
For high-end, double-sided white, and boxes → Choose white cardstock
For bright colors, flat printing, and no boxes → Choose coated paper
For cost performance, ordinary packaging, and no need to see the back → Choose gray back white cardstock
VI. Summary
White cardstock, coated paper, and gray back white cardstock are not necessarily the better the more expensive. It depends on the use.
For packaging, emphasizing stiffness and texture, white cardstock is preferred;
For picture books, posters, and pursuing colors, choose coated paper;
For cost control, ordinary inner packaging and outer packaging, gray back white cardstock is the most practical.
