Jelly is very profitable, with annual sales of tens of billions in China (among which Xizhilang and its Crystal Love brand account for about 33% of the market). China surpassed Japan to become the world's largest producer and seller of jelly. Jelly makes a lot of money, but what makes jelly more profitable is its packaging: bulk. Why bulk jelly? Instead of packaging it into one kilogram or half a kilogram for sale?
First of all, as far as supermarkets are concerned, they are willing to sell jelly in large quantities because they can make more money. Have you ever carefully observed that all jelly packages have thick plastic shells, and the weight of jelly packages accounts for almost 10% of the total weight. Many sweets are also in bulk, but the outer packaging of sweets is paper, which is not as exaggerated as jelly. The supermarket sells a lot of jelly, so I will sell these plastic packaging shells to you at the price of jelly.
For example, suppose that one kilogram of jelly packaging has a net weight of 500 grams, and the total weight including bags is 550 grams. Then, the supermarket can only sell it to you at 500 grams net weight. By changing the sales method, the supermarket earned 10% more jelly. If you add the weight of the large plastic bag provided by the supermarket, the weight will be even greater. So supermarkets like bulk jelly very much. This is the hidden profit secret of this industry.
