How to package fragile cakes by mail?

Method 1: The cake itself has a plastic package, and there is a grid made of plastic in the package, and the cake is placed in the grid.

Method 2: you can wrap it in insurance film first, then put it in a box with some soft cotton or medicinal cotton in the middle, so as to ensure that it will not be damaged during transportation.

Method 3: For the sake of food safety and packaging weight, foam filling is better. If it is in bulk, it is best to choose plastic boxes or cardboard boxes with medium hardness for packaging. If it is self-packaging, it is generally vacuum packaging or filled with inert gas. What needs to be done is to add a buffer to the cardboard box.
