What are the factors that affect the silver effect of PET silver paper?

The factors that affect the silver effect of PET silver paper mainly include the following aspects:

Quality of PET substrate:

The flatness, thickness uniformity, transparency, and mechanical properties of PET substrates directly affect the performance of Asian silver. Poor substrate quality may lead to uneven aluminum plating, affecting overall glossiness.

Vacuum aluminum plating process:

The thickness, uniformity, and adhesion of the aluminum plating layer are key factors affecting the effect of silver plating. Thin aluminum coating may result in insufficient glossiness, while thick coating may cause excessive reflection or color distortion.

The vacuum degree, temperature, pressure and other parameters during the aluminum plating process can also affect the quality of the aluminum plating layer.

Surface coating:

The type, formula, and coating process of coating materials can all affect the silver effect of PET silver paper. The coating can protect the aluminum plating layer while adjusting the glossiness and color.

The uniformity and adhesion of the coating are also important factors affecting the effect of silver.

Post processing technology:

Post processing techniques such as curing, cooling, and slitting can also affect the sub silver effect of PET sub silver paper. Insufficient curing may result in incomplete drying of the coating, affecting glossiness and durability.

Scratches or damages that may occur during the slitting process can also affect the overall appearance of PET silver paper.

Storage conditions:

If PET silver paper is exposed to adverse environments such as humidity, high temperature, and direct sunlight during storage, it may cause problems such as oxidation of the aluminum plating layer and coating peeling, thereby affecting the silver effect.

Handling during use:

Improper handling during printing, cutting, pasting, and other processes may also damage the silver effect of PET silver paper. For example, using inappropriate carbon tape or printing with high concentration may result in unclear printing or damage to the aluminum plating layer.

In summary, the silver effect of PET silver paper is influenced by various factors. In order to achieve high-quality silver effect, it is necessary to strictly control the process parameters and quality standards of each link in the production process, and pay attention to protecting PET silver paper from adverse environmental effects during storage and use.
