What are the differences in the production process of different PET thermosensitive matte silver paper mills?

There are indeed differences in the production process of different PET thermosensitive dumb silver paper mills, and these differences are mainly reflected in the following aspects:

First, raw material selection and ratio

1.Polyethylene terephthalate (PET) substrate: Different manufacturers may choose different brands, different purity PET substrates, and different thickness substrates to meet different application needs.

2.Additives and coating materials: In order to improve the performance of PET matte silver paper, such as scratch resistance, wear resistance, high temperature resistance, manufacturers will add different additives and coating materials. The types, proportions, and handling of these additives and coating materials may vary.

Second, the production process

1.Coating process: The coating of matte silver on the PET substrate is a key step in the production of PET matte silver paper. Different manufacturers may use different coater, coating speed, coating thickness and drying method after coating, which will affect the final performance of the product.

2.Vacuum aluminum plating: The production process of some PET matte silver paper may also involve vacuum aluminum plating process to further enhance its metallic texture and corrosion resistance. Different manufacturers may have differences in vacuum aluminum plating equipment, aluminum plating conditions and treatment methods after aluminum plating.

3.Composite and die cutting: For PET matte silver paper that needs to be composed of other materials or specific shapes, different manufacturers may also differ in the composite process, die cutting accuracy and subsequent treatment.

Third, quality control and testing standards

1.Quality control system: Different manufacturers may use different quality control systems to ensure product quality, such as ISO quality management system. The differences in these systems will lead to differences in the monitoring and testing standards of each link in the production process.

2.Testing standards and methods: The manufacturer will test various performance indicators of PET matte silver paper in the production process, such as scratch resistance, wear resistance, high temperature resistance, color fastness, etc. Different manufacturers may use different testing standards and methods, which will also affect the final quality of the product.

Fourth, customization and innovation ability

1.Customized services: Some manufacturers may provide more flexible customized services, which can adjust the production process and formula according to customer needs, and produce PET matte silver paper that meets specific requirements.

2.Innovation capacity: There are also differences in the investment and innovation capacity of different manufacturers in the development of new products and new processes. Some leading manufacturers may have more patented technologies and innovative achievements, and can constantly introduce new products with market competitiveness.

In summary, there are differences in the production process of different PET thermal matte silver paper manufacturers in raw material selection and ratio, production process flow, quality control and testing standards, and customization and innovation capabilities. These differences make the PET dumb silver paper products on the market have diversity and difference, and can meet the needs of different industries and customers.
