Cupstock Paper for Paper Cups
What Is Cupstock Paper
Cupstock paper is specifically designed for making cups. Manufacturers use white cardboard made from chemically processed wood pulp. This material is ideal for food packaging, such as hot and cold drinks. They add coatings like PE, PLA, or water-based coatings to the paper. These coatings prevent water and oil leakage. The smooth surface allows for easy printing of vibrant colors and logos.
Sure Paper uses only 100% virgin wood pulp to produce cupstock paper. This makes the paper strong, durable, and meets food safety standards. The company offers a variety of papers for making cups. Some are uncoated, some are laminated, and some are coated. Each type of paper is suitable for different uses, such as coffee cups, ice cream cups, or soup bowls. Businesses can choose the most suitable paper based on their needs.
Cupstock paper has special physical and chemical properties. These properties make it ideal for making cups. The following table lists important details:
| Property | Description | Typical Range / Notes |
|---|---|---|
| Basis Weight | Mass per unit area of paper | 70–120 gsm (Kraft & SBS common) |
| Thickness (Caliper) | Physical thickness of the sheet | Single-wall: 160–360 µm; Double-wall: 200–640 µm |
| Coating Type | Barrier treatment for liquid resistance | PE, PLA, water-based, or wax |
| Printability | Suitability for high-quality graphics | Excellent – smooth, clay-coated surface for full-color branding |
| Eco-Certifications | Environmental compliance standards | FSC, PEFC, or recycled content labels; compostable options |
Food-Grade Standards for Cupstock Paper

Types of Paper Used for Making Paper Cups
Virgin vs. Recycled Paper
When making cups, companies pick between virgin paperboard and recycled paperboard. Virgin paperboard is made from new wood pulp. It is strong, smooth, and looks clean. This paper makes cups feel fancy and keeps food safe. Recycled paperboard uses old paper fibers. It helps the planet by cutting down on waste. But, recycled paperboard is not as strong and can look dull.
The table below shows how virgin paperboard and recycled paperboard are different for making cups:
| Aspect | Virgin Paperboard | Recycled Paperboard |
|---|---|---|
| Quality | High strength, smooth, bright | Lower strength, may show specks |
| Food Safety | Excellent, best for direct contact | Used for outer layers or sleeves |
| Environmental Impact | Uses more resources, but can be certified | Reduces landfill waste, eco-friendly |
| Cost | Higher | Lower |
| Supply | Reliable | Depends on recycled supply |
Most of the cups have an inner lining made of virgin cardboard to ensure beverage safety and prevent leaks. The sleeve or outer lining uses recycled cardboard, which doesn’t come into contact with the beverage. Sure Paper uses certified paper to produce high-quality, safe, and environmentally friendly cups.
Kraft, White Cardboard, and Cup Board
Different paper types give cups special features. Kraft paper is very strong and lasts a long time. It is made from new fibers and is brown. Kraft paper does not tear easily and keeps out water. It is great for strong sleeves and eco-friendly brands. White cardboard is smooth and bright. It is perfect for printing logos and designs. This paper is used for fancy cups that need clear pictures.
Cup board is a special paperboard just for cups. It is stiff, strong, and smooth. Cup board works well with heat and water when coated. The table below shows how these papers are different:
| Linerboard Type | Printability | Strength | Cost |
|---|---|---|---|
| Kraft Paper | Good for logos | Very strong | Higher |
| White Cardboard | Best for sharp images | Varies | Varies |
| Cup Board | Smooth for printing | High stiffness | Moderate |
Tip: Kraft paper is best for strong, green sleeves. White cardboard and cup board are good for cups that need great printing and last a long time.
Cups made with the right paper work well and look nice. Sure Paper helps people pick the best kraft paper, white cardboard, or cup board for any cup.
