Carbon paper and NCR (No Carbon Required) forms are essential office supplies used for creating duplicate or triplicate copies of documents such as invoices, receipts, work orders, and delivery notes. For Southeast Asian merchants looking to sell on Alibaba.com, understanding the technical specifications that B2B buyers expect is crucial for successful export.
Unlike traditional carbon paper that requires a separate carbon sheet between documents, modern NCR paper uses micro-encapsulated dye and clay coating technology to create copies through pressure alone. This makes NCR forms more convenient, cleaner, and increasingly preferred in B2B transactions.
Key Product Attributes Explained:
GSM (Grams per Square Meter) - The universal standard for paper weight measurement. For NCR carbonless paper, the typical range is 48-70gsm, with 50gsm being the most common basis weight for standard business forms. Heavier weights (60-70gsm) offer better durability but come at higher cost.
Ply Layers (Part Configuration) - Refers to the number of copies produced per form:
- 2-part forms: Original (white) + 1 copy (canary yellow)
- 3-part forms: Original (white) + 2 copies (canary + pink)
- 4-part forms: Original (white) + 3 copies (canary + pink + blue/green)
Coating Types - NCR paper uses three coating configurations:
- CB (Coated Back): Coating on the back side
- CF (Coated Front): Coating on the front side
- CFB (Coated Front & Back): Coating on both sides for multi-part forms
