In daily life, especially in some markets, where raw poultry is sold, we can see crates, which are boxes with gaps between the boards. In fact, these boxes are made by moulds before they are finished, which is called crate mould .

As one of the packaging terms commonly used in foreign trade processes, crates are mostly used to hold breathable items. Because of its ventilation and convenient disassembly and assembly characteristics, it is deeply loved by people; it is mostly used in the transportation of medium and short-distance large and medium-sized goods. It is widely used in sea and air transportation. They can be seen in many home improvement markets, supermarkets, and large warehouses. Of course, there are also bottled crates specially used for beverages. Although traditional milk crates have long been one of the most popular ways to transport bottled beverages, modern manufacturers rely on many bottle box designs to meet their needs. Some designs can only hold a few bottles at a time, while others can hold dozens of bottles. A bottle crate can have a separate opening to separate each bottle from other bottles, or it can simply adopt an open design to hold the bottles tightly together.

There is not much difference between crate mould and other moulds in terms of design and processing or production. It is also very similar to the production of trash can mould , but the shape will be a little different.
