Calcium plastic corrugated box
1. The corrugated shape of corrugated cardboard
Corrugated paper has two methods: mechanical corrugated shape and vacuum forming. The mechanical forming device presses the calendered cardboard through two corrugated steel rolls that are mutually toothed to preheat to a softening temperature between tg and tf temperatures. In the shape of corrugated, then the other two pieces of preheated flat sheet and corrugated core material are pressed and bonded together by a pair or two pairs of rubber rolls to form a corrugated board with corrugated corrugated upper and lower flat plates. After cooling and shaping, after trimming, you can cut into a box shape.
2. Boxing and printing of corrugated board
The box making process of the calcium-plastic corrugated box is the same as the process of forming the cardboard into a box: according to the shape and size of the box, the line is pressed and pressed on the Wayang paperboard, printed (screen-printed) and then cut, and then nailed into a box.
3. Box structure of calcium hope corrugated box
Calcium plastic corrugated boxes have single corrugated boxes and double corrugated boxes and multi-watt boxes in corrugated layers. The more corrugated layers, the heavier the box, the more materials, but the higher the strength, the heavier the packageable goods. The better the performance, the common use of single corrugated, double corrugated for heavy duty packaging of mechanical parts.
According to the shape of the box, there are the following: The first type is the mouth type. This is the most common one. The bottom cover and the cover of the box are two and a half covers, which are just the width of the box. There is a seam in the middle. The material for the buckle cover is saved, and the empty box can be folded and stacked. The seams are often sealed with a strong adhesive tape. For this reason, it cannot be used for heavy objects. Otherwise, when the tape is applied, the adhesive tape is not enough to open the bottom cover, and the things are scattered. If the bottom cover is sealed with a large copper nail, the effect is better. Note that the cover should not be uncovered with tape. The second type of large cover type or single cover type. The width of each cover is equal to the width of the box, and one side can be made full and the other side can be half-covered. This box has the overall performance of the top and bottom, but the cabinet is also thin and cannot withstand excessive lateral impact. The third type of heaven and earth cover. The whole box is composed of two parts, the bottom and the cover. The upper and lower covers are integrated. After the bottom and the cover are closed, the box becomes double-layer corrugated, so the overall integrity is strong and can withstand. The big pressure and impact force, the shortcoming of the box is that the empty box can not be folded, using more raw materials and more expensive. This type of box is suitable for the packaging of items that are cumbersome and do not allow impact. In addition, there are active sleeves, caps, and caps.
