Playing cards are a common toy in our leisure time, so, do you know how it is produced?

The process flow of each step is as follows:

1️⃣Design plate making

That is, the design of the front and back of the playing card, the design of the playing card packaging box, and the printing plate making.

2️⃣Material preparation and modification

The company will physically modify the special paper for playing cards in stock for a certain period of time. Due to the uneven internal stress of the newly-produced paper, wrinkles are easily formed in the area where the internal stress is concentrated, and the produced playing cards are unstable in terms of flatness, elasticity, and folding endurance, thus affecting the overall quality of the playing cards. Through the modification process, the company can effectively improve the quality of paper, so as to ensure that the quality of special paper for playing cards is significantly better than the industry average.

The specific requirements for the modification of special paper for playing cards are as follows:

①Requirements for paper stability. Paper is a thin layer material interwoven with natural plant fibers, therefore, paper has strong hydrophilic ability. The newly produced paper needs to go through long-distance transportation before it can be stored in the company's warehouse, and the difference in temperature and humidity between the production site and the use site also makes the paper inevitably affected by the external environment and absorbs or releases water to cause deformation, thereby affecting printing, post-processing. processing and product quality. Therefore, it is very important to achieve a relative balance between the moisture of the prepress paper and the humidity of the external environment.

②Requirements for paper flatness. Paper is a multiphase complex and homogeneous polymer material with elastic properties and time-dependent flow properties, both elastic and viscous. The paper will be deformed when it is subjected to external force. Even after the external force is withdrawn, it is still partially deformed and cannot return to its original shape, that is, permanent deformation. In the production process of paper, the paper mill generally rolls the output paper into a roll shape, and then unrolls it and cuts it into flat paper. Although the bending phenomenon of the paper can be partially recovered after being cut into flat paper, there are still some deformations that cannot be recovered. Therefore, if the purchased paper is directly put into production, it is easy to cause warping of playing cards, which will have a negative impact on the production process and the quality of the final product. Therefore, it is necessary to apply appropriate external force to eliminate the paper caused by these poor stress and deformation. warping problem.

The specific measures taken by the company to meet the demand for paper modification:

① Store the paper in a specific environment for a certain period of time, and balance the moisture of the paper with the humidity of the external environment. After the company has carried out continuous experiments on the use of paper, it has been proved that under a certain environment, the paper that has been placed for about three months will reach a good state in terms of dimensional stability, and the paper will no longer have obvious expansion and contraction problems. The improvement of poker paper printing inaccuracy and the problem of unilateral size heads in the subsequent process.

② Store the paper in a specific environment for a certain period of time, deal with the stress and deformation of the paper, eliminate the bad stress (warping), and achieve the best flatness. According to the theoretical elaboration of the relationship between paper stress and time in "Paper Structure and Properties" published by China Light Industry Press in 2006, the company combined the actual situation and stored the newly produced playing card flat paper for three months. Time to eliminate the poor warpage stress of the paper and the poor curl stress caused by the roll. Three thousand pieces of flat playing card paper are stacked in a rack and stored for three months, which can well eliminate permanent benign deformation, and the product quality is significantly improved.

Procurement of paper - paper modification - to be used

3️⃣Printing

That is, the front and back printing of playing cards and the printing of playing card packaging boxes. The company adopts Heidelberg series printing machines with world-leading technology to improve printing efficiency and ensure high-quality printing results. The printing process of playing cards must be carried out in the order of "front first and then reverse", that is, after the front printing is completed, the reverse printing can be carried out after about 12 hours of circulation; after 5-7 days of circulation, the ink will be dry before can go to the next process. The company adopts advanced printing equipment, and its operation efficiency has been greatly improved compared with the traditional production process.

4️⃣Inspection, embossing

The inspection is to check whether the printed playing cards meet the production requirements and specifications. The playing cards that meet the requirements and specifications can enter the embossing process, that is, the machine is used to emboss the front of the playing cards. The company adopts a fully automatic product inspection machine, which realizes the two processes on one machine to improve production efficiency.

Embossing can improve the special feel of playing cards and improve the grade of playing cards. At present, most of Yaoji Poker's products are embossed, and products that do not need embossing enter the glazing process after the inspection process.

5️⃣Glazing

Glazing is an important step in the manufacturing process of playing cards. There are many detailed processes for glazing, and both the front and back of the playing cards need to be varnished. The company adopts a double-layer two-way glazing machine with two-layer playing cards to realize the full automation of the process, which not only improves the production efficiency but also saves the loss of raw materials, and strictly controls the product quality.

6️⃣Slitting

That is, the playing card paper is cut into standard playing cards. The traditional production process goes through two steps: indentation, manual carding and corner cutting. By adopting the "orderly collection method after paper cutting" technology, the company can complete the slitting and corner cutting at one time, simplify the production process, and improve the production efficiency and product quality.

7️⃣Finished product

• The finished product steps are divided into three categories according to the form of product packaging: outsourcing, carton inner packaging, and special inner packaging.

• Outsourcing is a packaging method in which the playing cards are first wrapped into a paper card case, and then the carton is sealed with BOPP plastic film.

• The inner packing of the carton is a packaging method in which the playing cards are first sealed with BOPP plastic film, and then put into the paper card box.

• The special inner package is a packaging method in which the playing cards are sealed with BOPP plastic film, and then put into a special box.
