What is the production process of PET matte silver label paper?

The production process of PET matte silver label paper mainly includes the following steps:

1、 Material preparation

PET substrate: High quality PET film is selected as the substrate, which has excellent physical properties and chemical stability, and is suitable for making label paper.

Ink and Coating: Prepare ink and special coating materials suitable for PET materials, which should have good adhesion and durability to ensure the printing effect and long-term use of label paper.

2、 Preprocessing

Surface cleaning: Clean the surface of PET film to remove impurities such as dust and oil to ensure good adhesion of ink and coating.

Surface pretreatment: Pre treat the surface of PET film through high-voltage discharge or other methods to improve surface energy or wetting ability, and enhance the stability of ink. The surface tension after pretreatment should meet the specified standard to ensure that the ink is not easily peeled off.

3、 Coating and printing

Coating with special coating: Apply a special matte silver coating on the surface of PET film, which can give the label paper matte silver effect and waterproof and oil resistant functions. During the coating process, it is necessary to control the uniformity and thickness of the coating to ensure the overall quality of the label paper.

Layout design and printing: Based on customer needs, layout design is carried out, including the selection and layout of elements such as fonts, colors, patterns, etc. Review and modify the layout after completion to ensure its accuracy and correctness. Then place the designed layout on the printing machine, adjust the position and angle, and start printing. During the printing process, it is necessary to control the printing speed and pressure to ensure the clarity and color brightness of the labels.

4、 Drying and solidification

Drying treatment: After printing is completed, the label is dried. The drying temperature and time need to be adjusted according to the characteristics of the ink and the label material to ensure the drying speed and adhesion performance of the ink.

Curing treatment: For certain special coatings or inks, curing treatment may be necessary to enhance their adhesion and durability. The curing process is usually carried out under specific temperature and time conditions.

5、 Fitting and cutting

Adhesive material bonding: The dried and cured label is bonded to the adhesive material. Pay attention to the control of bonding temperature and pressure to ensure the flatness and firmness of the label.

Cutting and slitting: Cut and slitting the bonded labels according to requirements for subsequent use and processing. During the cutting process, it is necessary to ensure that the size and shape of the label are accurate and correct.

6、 Quality inspection and packaging

Quality inspection: Conduct quality inspection on the finished matte silver labels, including checking the clarity, color, flatness, firmness, etc. of the labels. Quality inspection is an important part of ensuring product quality and requires strict adherence to standards.

Packaging and Storage: Pack qualified labels and label and store them according to customer requirements. During the packaging process, attention should be paid to protecting the integrity of the labels and avoiding damage.

In summary, the production process of PET matte silver label paper includes multiple steps such as material preparation, pretreatment, coating and printing, drying and curing, bonding and cutting, as well as quality inspection and packaging. Each stage requires strict control of quality and process parameters to ensure the quality and performance of the final product.
