What are the physical performance indicators of PET silver paper?

The physical performance indicators of PET silver paper mainly include the following aspects:

Thickness:

The thickness of PET silver paper is usually within a certain range, and common specifications include 25 fold (1 fold=1um), 50 fold, 75 fold, etc. The consistency of thickness has a significant impact on its application performance and printing effect.

Hardness and brittleness:

PET silver paper has good hardness and brittleness, which enables it to maintain good shape stability and durability during application.

Tensile strength:

Tensile strength is the ability of PET silver paper to resist tensile deformation. This indicator is of great significance for evaluating the durability and stability of PET silver paper under external forces.

Tear strength:

Tear strength refers to the ability of PET silver paper to resist tearing when subjected to tearing force. PET silver paper typically has high tear strength, which allows it to maintain good integrity under harsh environmental conditions.

Heat resistance:

PET silver paper can withstand certain high temperatures, and its high temperature resistance can usually reach 180 degrees or even higher. This enables PET silver paper to maintain good physical properties and color stability even in high temperature environments.

Chemical corrosion resistance:

PET silver paper has excellent chemical corrosion resistance and can resist the erosion of various chemicals such as acid, alkali, solvents, etc. This performance makes PET silver paper have a wide range of application prospects in industries such as chemical and pharmaceutical.

Waterproof and oil resistant:

The surface of PET silver paper has undergone special treatment and has good waterproof and oil resistant properties. This allows PET silver paper to maintain good appearance and performance in damp or greasy environments.

Transparency:

PET silver paper has excellent transparency and can clearly display printed content or label information. This is particularly important for industries that require high-quality printing effects, such as electronics, jewelry, etc.

Wear resistance:

The surface of PET silver paper has been treated with abrasion resistance and has high abrasion resistance. This makes PET silver paper less prone to damage or fading when used for a long time or subjected to friction.

In summary, PET silver paper has various excellent physical performance indicators, which enable it to perform well in various application scenarios. Specific performance indicators may vary depending on the manufacturer, so in practical applications, they need to be selected according to specific needs.
