Folding method of post-80s paper packaging

The folding method of post-80s paper packaging is as follows:

1. Prepare a square piece of paper, fold its diagonal into two triangles, and then fold the upper part of the diagonal downward to make it coincide with the lower part. Fold the left and right triangles inward so that they coincide with the square in the middle. At this point, you will get a shape similar to a diamond.

2. Fold down the top half of the diamond to make it coincide with the bottom half. Then, fold the left and right parts inward to make them coincide with the square in the middle. Open the paper and you will see that a square is divided into four small squares. Next, fold down the top half of each small square so that it coincides with the bottom half.

3. Unfold the paper again and you will see that each small square is divided into two smaller squares. Now, you can start folding the parts of the paper bag. Fold down the top half of each small square so that it coincides with the bottom half. Then, fold the left and right parts inward to make them coincide with the square in the middle.

4. Repeat the above steps until you fold all the small squares into diamonds. Finally, fold all the parts of the paper bag according to your favorite way, and a simple post-80 s paper bag is completed.

1, paper bag is a common packaging method, which is used to protect and package goods. It is usually made of paper, which has certain strength and durability and can effectively prevent goods from being damaged or polluted.

2. The process of making paper bags is relatively simple. First, select suitable paper materials, such as kraft paper and corrugated paper, and then cut and fold according to the size and shape of the goods. In the process of folding, it is necessary to keep the paper flat and tight to ensure the stability and reliability of the packaging.

One of the advantages of paper bag is environmental protection. Compared with non-degradable materials such as plastic packaging, paper can be recycled, reducing the environmental burden. In addition, paper bags can also increase the attractiveness and brand image of goods through printing and decoration.

However, paper bags also have some disadvantages. First of all, compared with plastic packaging and other materials, the strength of paper is low and it is easily damaged by external forces. Secondly, paper bags are not suitable for all types of goods, especially fragile, liquid or wet goods, and other more suitable packaging methods are needed.

In order to improve the quality and protective performance of paper bags, some manufacturers will adopt additional treatment methods, such as film covering and thickening. These treatments can improve the water resistance, moisture resistance and wear resistance of paper bags, thus better protecting goods.
