Packaging paper trays are products that need to be molded and customized. Different customers will have their own needs and filtering during the procurement process. The following editor summarizes some common questions about customers purchasing paper trays for everyone to answer!
1. What are the types of paper tray raw materials?
At present, the raw materials used in paper tray products are mainly divided into two categories, one is raw pulp, and the other is recycled. However, paper trays produced with different raw materials differ in appearance, performance, and price. .
2. Why are the weights of paper tray products different?
The main reason is that the consistency of the pulp is changing. The processing process of the pulp with a good consistency will start to change after the formed paper tray is separated, but the paper tray manufacturers generally control it between 2.56% and 3.6%. Another reason is that because the negative pressure value of the air compressor in the molding process is also variable as the production progresses, the vacuum is constantly changing, so the weight of each paper tray is slightly different.
3. Can every color be dyed enough?
I believe everyone has seen packaging paper tray products of different colors, so some customers think that paper trays can be dyed in different colors. The dyeing of paper trays is mostly based on the addition of water-based dyes to the original pulp. However, as the slurry concentration changes and temperature changes during the production process, the dyes will also change with the progress. Most dyes have higher temperature requirements, so the color Products with higher requirements should not be dyed.
