Yondo Corrugated Plastic Products Ltd

Dyne level is an important factor when printing on PP corrugated plastic sheets. Because polypropylene (PP) naturally has a low surface energy, printing ink may not adhere well to an untreated PP surface. Measuring the dyne level helps determine whether the sheet has sufficient surface energy for reliable ink adhesion.

Dyne level, usually expressed in dynes/cm, indicates the surface tension or surface energy of a material. A higher dyne level generally means that the surface is easier for inks, coatings, or adhesives to wet and bond to. For PP corrugated sheets used for signs, displays, packaging, and other printed applications, an appropriate dyne level can help improve print quality and durability.

Untreated PP sheets typically have a relatively low surface energy, which can cause problems such as poor ink coverage, uneven printing, ink peeling, or reduced adhesion. To improve printability, PP sheets can undergo surface treatment, such as corona treatment. Corona treatment increases the surface energy of the PP material, allowing printing ink to spread more evenly and form a stronger bond with the surface.

Before printing, a dyne test can be used to check whether the surface treatment has reached the required level. This is especially useful for customized PP corrugated sheets because different printing methods and inks may have different surface-energy requirements. Regular testing can also help maintain consistent printing performance during production.

At Mantis, we can provide PP corrugated plastic sheets with surface treatment for different printing requirements. Our sheets can be customized for screen printing, UV printing, and digital printing applications. By controlling the surface treatment and checking the dyne level, we help customers achieve better ink adhesion and more consistent printing results.

If you are looking for printable PP corrugated sheets, the required dyne level, printing method, sheet thickness, and application should all be considered before production. Contact us with your printing requirements, and we can recommend a suitable PP sheet solution for your project.
