What is Polyurea paper (Copy paper)?
Poluya paper, also known as copy paper, is a thin, lightweight type of paper specially manufactured to create multiple copies simultaneously when writing or typing. The distinguishing feature of Polyurea paper lies in its moderate transparency, allowing the pressure from a pen or typewriter to transfer through to the carbon paper layer underneath, thereby producing a copy on the sheet behind. Polyurea paper was once an indispensable “tool” in office work, education, and many other fields before the advent of photocopiers and printers.
Properties and Characteristics of Polyurea (Copy) paper
- Thin, smooth surface, minimal paper dust: This characteristic helps reduce friction when writing or typing, ensuring that the ink adheres evenly and produces sharp, smear-free text.
- Moderate transparency: Polyurea paper is designed with moderate transparency, permitting the pressure from ballpoint pens, pencils, or typewriters to impact the carbon paper layer underneath, creating a copy on the sheet below.
- Moderate ink absorption: Polyurea paper does not absorb ink too quickly or too slowly, allowing the ink to dry rapidly without bleeding or smudging, while still ensuring colorfastness for both the original and copies.
- Suitable for both ink pens and typewriters: Polyurea paper is compatible with various writing instruments such as ballpoint pens, pencils, fountain pens, and typewriters, meeting diverse usage needs.
Specifications you need to know about Polyurea (Copy) paper
Transparency
Polyurea paper needs to have moderate transparency, allowing the pressure from a pen or typewriter to transfer to the carbon paper layer beneath while ensuring sharpness for the original. If the paper is too transparent, the original will be blurred and hard to read. Conversely, if the paper is too opaque, the copy will not be clear.
Size
The most common size is A4 (210 x 297 mm). A more compact size often used for notebooks, pads, and notes is A5 (148 x 210 mm). The smallest size in the A series, typically used for business cards, memo slips, and name tags, is A6 (105 x 148 mm).
Weight
Weight is the most important specification for paper in general and Polyurea paper in particular, indicating the mass of the paper per unit area, usually measured in grams per square meter (g/m²). For Polyurea paper, the weight typically ranges from 45 g/m² to 60 g/m². Higher weight means thicker, sturdier paper with less ink absorption, suitable for originals when writing or typing. Conversely, lower-weight Polyurea paper is thinner and absorbs ink faster, making it suitable for copies.
Applications of Polyurea (Copy) paper in industry
Printing and publishing
Despite the availability of modern printers, Polyurea paper is still used in specific cases such as small print runs, sample printing, or printing publications that require high security. The reason is that printing costs on Polyurea paper are lower compared to using printers, while still ensuring colorfastness and sharpness.
Garment and footwear
In the garment and footwear industry, Polyurea paper is used for pattern drafting, creating copies of clothing and shoe details. Polyurea paper is easy to draw on, easy to cut, and cost-effective, making it suitable for mass production.
Handicrafts
With its thin, lightweight, and easy-to-shape characteristics, Polyurea paper is also used in some handicraft fields such as making paper flowers, decorating cards, and shaping handmade products.
