What is the customization process for long-lasting three proof thermal paper?

The customization process of long-lasting three proof thermal paper usually includes the following steps:

1、 Requirement analysis

Communication requirements:

Communicate in detail with the customer to understand their specific requirements for long-lasting three proof thermal paper, including size, shape, color, material, coating, printing content, quantity, and special processes.

Determine specifications:

Determine the specifications of thermal paper based on customer needs, such as paper thickness, width, length, etc.

2、 Raw material preparation

Choose base paper:

Choose high-quality paper with a certain thickness and strength as the substrate, usually using high-quality wood pulp paper to ensure stability and durability during the printing process.

Preparation of thermal sensitive coatings:

According to customer requirements, prepare suitable thermal sensitive coatings. Thermal sensitive coatings are composed of thermal sensitive raw materials (such as colorless dyes, color developing agents, etc.), adhesives, additives, etc., which need to be mixed and prepared according to a certain formula ratio.

3、 Production and processing

Coating thermal sensitive coatings:

Use a roller or other coating equipment to evenly apply the thermal sensitive coating onto the paper substrate. During the coating process, it is necessary to control the thickness and uniformity of the coating to ensure printing quality.

Drying and curing:

After coating is completed, the paper needs to undergo drying and curing treatment to remove moisture from the coating, so that the coating can firmly adhere to the paper and achieve the best printing effect. Drying methods may include oven drying, high-frequency drying, airflow drying, or rapid drying with ultraviolet lamps.

Add protective layer (optional):

For long-lasting three proof thermal paper, a protective layer is usually added on top of the thermal coating to improve the paper's waterproof, oil resistant, and friction resistant properties. The coating and drying method of the protective layer is similar to the production of thermosensitive coatings.

4、 Cutting and packaging

Splitting:

Cut the coated and dried thermal paper according to the customer's required specifications to form single sheet or roll label paper.

packing:

Pack the cut thermal paper to prevent moisture, contamination, and damage. The packaging material is usually moisture-proof paper or plastic film, and is labeled with relevant product information and usage instructions.

5、 Quality inspection

Strict quality inspection is required for raw materials, semi-finished products, and finished products throughout the entire production process. The testing content includes the flatness of the paper, the uniformity of the coating, the printing effect, durability (such as waterproof, oil proof, anti friction performance), and whether it meets other special requirements of the customer.

6、 Delivery and after-sales service

Delivery:

Deliver the customized long-lasting three proof thermal paper to the customer according to the agreed time and method.

after-sale service:

Provide necessary after-sales services, such as usage guidance, technical support, return and exchange services, etc., to ensure customer satisfaction with the product.

In short, the customization process of long-lasting three proof thermal paper is a complex and delicate process that requires strict control of each link to ensure product quality. Through professional customization services, we can meet customers' needs for special label paper.
