Where is the process difference of PET dumb silver paper produced by different manufacturers?

The process differences of PET dumb silver paper produced by different manufacturers are mainly reflected in the following aspects:

First, raw material selection and treatment

1.PET substrate selection: Different manufacturers may choose different brands and different specifications of PET substrates as raw materials for production. These substrates may differ in terms of physical properties, chemical stability, etc., which can affect the performance of the final product.

2.Pretreatment process: The pretreatment process for the PET substrate may also be different before the matte silver coating is applied. Some manufacturers may use more complex pretreatment steps, such as surface cleaning, corona treatment, etc., to improve the adhesion of the coating to the substrate.

Second, dumb silver coating formula and coating process

1.Dumb silver coating formula: Different manufacturers will develop different dumb silver coating formulas according to market demand and their own technical strength. These formulations may have differences in the proportion of ingredients, types of additives, etc., which will affect the gloss, stain resistance, scratch resistance and other properties of matte silver paper.

2.Coating process: Coating process is also one of the key factors affecting product quality. Different manufacturers may use different coating methods (such as scraper, roll coating, etc.), coating speed and coating amount, as well as different drying temperatures and times, which will affect the uniformity and adhesion of the matte silver coating.

Third, post-processing and quality control

1.Post-treatment process: After coating is completed, some manufacturers may carry out additional post-treatment processes, such as calender, laminating, etc., to improve the appearance quality and durability of the product. The specific steps and parameters of these post-treatment processes may also vary from manufacturer to manufacturer.

2.Quality control: There may also be differences in quality control between different manufacturers. Some manufacturers may have more advanced quality testing equipment and more stringent quality control standards to ensure that the performance and quality of each batch of products meet the predetermined requirements.

Fourth, technology and innovation capability

1.Technology research and development strength: the technology research and development strength of different manufacturers is different, which directly affects the innovation and competitiveness of products. Some manufacturers with strong research and development strength can continue to introduce new products and new processes to meet the changing and upgrading needs of the market.

2.Customized production capacity: With the diversification of market demand, some manufacturers may pay more attention to the construction of customized production capacity. They are able to provide personalized solutions and product customization services according to the specific needs of customers, thus occupying an advantageous position in the market competition.

In summary, the process differences between different manufacturers of PET matte silver paper are mainly reflected in raw material selection and treatment, matte silver coating formula and coating process, post-treatment and quality control, as well as technology and innovation capabilities. These differences make the products of different manufacturers show their own characteristics and advantages in performance, quality, appearance and so on.
