What is the water and oil resistance of circular colored copperplate paper?

The water resistance and oil resistance of circular colored copperplate paper mainly depend on its material and manufacturing process. The following is a detailed analysis of these two aspects:

1、 Water resistance

Basic characteristics:

Copperplate paper is a high-quality printing paper made from high-quality wood pulp as raw material. Its surface has been specially treated to make it smooth and flat, making it suitable for producing high-quality printed materials.

Copperplate paper usually has certain waterproof performance, especially after special waterproof treatment, its waterproof performance is even better.

Water resistance performance:

In general, circular colored copperplate paper can withstand certain moisture contact and will not immediately show obvious deformation or fading.

However, if soaked for a long time or exposed to high temperature and humidity environments, the printing effect of copperplate paper may be affected, resulting in discoloration, blurring, or peeling.

Usage suggestion:

In order to maintain the printing effect of circular colored copperplate paper and extend its service life, it is recommended to avoid prolonged exposure to moisture or being in a humid environment.

When storing and using, the environment should be kept dry, ventilated, and avoid direct sunlight.

2、 Oil resistance

Basic characteristics:

Copperplate paper is usually not resistant to oil or various solvents.

Oils and solvents can easily penetrate paper fibers, causing paper deformation, fading, or damaging printing effects.

Oil resistance performance:

When circular colored copperplate paper comes into contact with grease, there may be oil stains, discoloration, or blurry printed content.

Long term exposure to grease or solvents may even cause paper to break or dissolve.

Usage suggestion:

When using circular colored copperplate paper, direct contact with grease and solvents should be avoided.

If it needs to be used in oily environments, it is recommended to choose copperplate paper with special oil resistant treatment or use other more suitable paper materials.

In summary, circular colored copperplate paper has certain limitations in terms of water and oil resistance. When using, suitable paper materials should be selected according to specific needs and environmental conditions, and corresponding protective measures should be taken to extend the service life and maintain the printing effect.
