Carbonless Copy Paper (NCR paper) is a special type of paper that can be duplicated without the use of toner. This paper is usually composed of upper page paper (CB paper), middle page paper (CFB paper) and lower page paper (CF paper), and the color transfer between them is achieved by microencapsulation technology. When pressure is applied to the paper, the microcapsules break, enabling the reproduction of words or images.

The application of carbon-free carbon paper is very wide, mainly including the following aspects:

1. Business forms:
NCR paper is often used to make multiple business forms, such as invoices, receipts, orders, etc. These forms need to record the same information on different links at the same time, without the use of carbon paper or toner to achieve the duplication effect.

2. Office documents:
In the office environment, NCR paper is also commonly used to make memos, internal notices and other documents, which is easy to copy and distribute.

3. Medical records:
In the medical field, NCR paper is used to make medical records such as medical records and prescriptions to facilitate the transfer of information between doctors and patients.

4. In the field of education:
In educational institutions, NCR paper can be used to make transcripts, exam answers, etc., to facilitate record and statistics of results.

5. Logistics and transportation:
In the logistics and transportation industry, NCR paper is used to make waybills, packing lists, etc., to facilitate the tracking and management of goods.

6. Financial industry:
In banks and financial institutions, NCR paper is used to make financial documents such as checks, deposit slips, and loan contracts.

7. Retail:
In retail stores, NCR paper is used to make sales receipts, returns, etc., to facilitate the preservation and inquiry of sales records.

8. Service industry:
In the service industry, NCR paper is used to make service orders, maintenance records, etc., to facilitate the recording and tracking of service processes.

Carbon-free carbon paper, also known as no-carbon-required (NCR) paper, is indeed a significant innovation in the realm of office supplies and business operations. Its unique design allows for the creation of multiple copies of a document without the need for traditional carbon paper, which can be messy and less efficient.
