1. Definition: A base paper model is a coded representation of key technical parameters, including type, grammage, dimensions, and processing treatments. Different models correspond to specific applications and manufacturing processes.
2. Structure of Model Codes:
- Type Code: Denoted by letters (e.g., K for kraft paper, B for white card paper, H for writing paper).
- Grammage: Expressed numerically (e.g., 40 indicates 40 g/m²).
- Size Specification: Indicated by alphanumeric codes (e.g., A4 = 210 × 297 mm, B5 = 176 × 250 mm).
- Processing Code: Letters denote treatments (e.g., P for coating, C for embossing, R for printing).
3. Common Models and Applications:
- Kraft Paper (K1–K5): Used for packaging bags, garments, and accessories.
- White Card Paper (B1–B5): Suitable for cards, folders, and cartons.
- Writing Paper (H1–H5): Ideal for office documents, envelopes, and correspondence.
- Coated Paper (C1–C5): Designed for high-quality prints such as albums and commemorative publications.
4. Selection Guidance:
- Understand each parameter's significance to select the appropriate model.
- Consider thickness and stackability for efficient processing and printing.
- Balance cost and performance; avoid over-specifying based on brand alone.
Understanding base paper model designations is essential for effective material selection and application.
