Technical Guide: Choosing the Right GSM for Your Packaging Needs #
Understanding GSM and Its Impact on Packaging
When selecting C1S paper for your packaging, GSM, or grams per square meter, measures the paper weight of C1S paperboard. It is an important starting point for comparing packaging materials, but actual thickness, stiffness, durability, and folding performance can still vary by paper grade, density, coating, and production process. Choosing the right GSM ensures that your packaging achieves both the desired durability and aesthetic appeal.
Low GSM values result in lighter, more flexible paper, ideal for custom bags and sleeves, while higher GSM values provide greater strength and rigidity, making them suitable for more demanding applications like folding cartons or heavy-duty packaging.
GSM Table for C1S Paper
Here’s a guide to comparing common C1S paper GSM levels with approximate thickness and packaging uses:
| Paper Weight (GSM) | Thickness (mm) | Commonly Used For |
|---|---|---|
| 210gsm | 0.27mm | Paper Bags, Sleeves |
| 230gsm | 0.30mm | Paper Bags, Book Covers |
| 250gsm | 0.33mm | Paper Bags, Book Covers, Box Inserts |
| 300gsm | 0.40mm | Folding Boxes, Luxury Paper Bags, Box Inserts |
| 350gsm | 0.48mm | Folding Boxes, Paper Tags, Box Inserts |
| 400gsm | 0.55mm | Folding Boxes, Paper Tags, Box Inserts |
These C1S paper weight and thickness values are general references for packaging. Actual thickness can vary between paper mills, paper grades, fiber structure, density levels, coatings, calendering, and production processes.

C1S vs. C2S Paper #
C1S (Coated One Side)
- Weight & Thickness: Typically ranges from 210-400gsm, with some mills offering from 170gsm to 550gsm. C1S is generally 0.1-0.15mm thicker than C2S of the same weight, offering better rigidity.
- Color: C1S tends to be less white than C2S on the coated side, but high-end C1S can achieve similar whiteness for luxury packaging.
- Printing Performance: C1S offers strong visuals on one side, but the uncoated reverse side results in darker colors due to ink absorption.
- Coating: The back side of C1S is limited to basic coatings like machine varnish and aqueous coatings.
- Cost: More cost-effective than C2S due to simpler production.
Best For: Custom folding cartons, white paper bags, and inserts that need only one printed side and lower cost.
C2S (Coated Two Sides)
- Weight & Thickness: Generally ranges from 80-400gsm. Though thinner than C1S of the same weight, C2S offers a denser paper fiber structure.
- Color: Typically whiter than C1S, making it a top choice for products demanding vivid color reproduction on both sides.
- Printing Performance: C2S provides more vibrant and consistent color on both sides with lower ink absorption, making it ideal for double-sided printing.
- Coating: Both sides can receive identical coatings, offering more versatility in finish options.
- Cost: Higher production complexity makes C2S more expensive.
Best For: Brochures, catalogs, book covers, and other premium double-sided printed materials.
Additional Practical Insights
- Adhesion: The uncoated back of C1S offers better glue absorption, improving bonding strength over C2S.
- Printing Plates(Offset Printing): When C2S paper is used for double-sided printing, and the layout has an even number of items arranged either vertically or horizontally, only one set of printing plates is required. This method, known as self-reverse printing, allows for efficient use of materials. However, with C1S paper, even in similar layouts, two separate sets of printing plates are needed—one for the coated front side and one for the uncoated back side—resulting in higher printing costs for dual-sided jobs.
Conclusion: Both C1S and C2S have their unique advantages. C1S is better suited for single-sided packaging with cost and sturdiness in mind, while C2S is perfect for high-quality, double-sided prints where visual consistency and vibrancy are key. The right choice depends on your specific packaging needs and budget.
