YUPO is a synthetic paper made mostly from polypropylene film to which inorganic fillers and small amounts of additives are added. In principle, the film is formed while creating microvoids by stretching it biaxially. The most distinguishing feature is its multilayer construction, which consists of a base layer and paper-like layers laminated on either side, whose thickness can be adjusted to provide products ranging from thin to thick.

YUPO's unique production
method is patented
around the world.

YUPO is made up of 3 layers. The base layer is stretched both lengthwise and crosswise, while the surface layer is stretched crosswise (bi-axially oriented film forming process). This production method is only possible because of our unique technology, which is protected by patents around the world, including in Japan, America, and China.

YUPO 's Structure

Strength comes from the base layer, while the paper-like characteristics come from the surface layers.

YUPO is a synthetic paper made up of 3 layers: a base layer and a surface layer laminated to each side. The base layer gives YUPO strength, while the stretching process provides the surface layer with innumerable micro-voids (microscopic pores), which make it very white, as well as lightweight and suitable for handwriting.

Check YUPO 's grain

Just like paper, YUPO  has a grain. The grain runs along the first dimension listed in the label, so make sure you check this before use. Many YUPO sheets have a short grain; however some products that are prone to fanning out (inaccurate registration) have a long grain.

The grain direction
has double the stiffness.

For uses that require stiffness, such as swing POPs, make sure the grain is aligned with the curve. The stiffness in the direction of the grain has twice that of the grain.
