In packaging and printing, paper selection directly impacts product presentation, protection, and cost. Understanding the distinctions between core paper types is critical for optimal results.

Coated paper (also called art paper) features a clay coating on its surface, delivering high smoothness and gloss. With a grammage range of 80–300 gsm, it excels at reproducing vibrant colors and fine details, making it ideal for high-end packaging (e.g., cosmetics boxes, gift bags) and promotional materials. However, its coating reduces water absorption, limiting suitability for wet environments.

Offset paper (uncoated) lacks surface treatment, offering natural absorbency and a matte finish. Grammage typically ranges from 60–120 gsm, and it performs well with text-heavy prints like product manuals or food labels. It's cost-effective and compatible with both digital and offset printing, though color saturation is lower than coated paper.

Corrugated paper consists of a fluted inner layer and outer liners, providing exceptional cushioning and structural strength. Grammage varies by application (120–250 gsm for liners), and it's widely used for shipping cartons and protective packaging. Single-wall (E-flute) suits lightweight items, while double-wall (B/C-flute) handles heavier loads. Its recyclability aligns with sustainable packaging trends.

Kraft paper is made from unbleached wood pulp, offering high tear resistance and a natural brown appearance. Grammage ranges from 80–150 gsm, and it's popular for eco-friendly packaging (e.g., grocery bags, product wraps). It accepts simple printing (flexography) and is often used for packaging that emphasizes sustainability.

Specialty paper includes textured, metallic, or recycled variants, designed to enhance brand differentiation. Grammage varies (100–200 gsm), and applications include luxury packaging (e.g., perfume boxes) or limited-edition products. While more expensive, it elevates tactile and visual appeal.

In summary, coated paper prioritizes color vibrancy, offset paper balances cost and readability, corrugated paper focuses on protection, kraft paper emphasizes sustainability, and specialty paper delivers uniqueness-each tailored to specific packaging needs.
