According to the search results provided, Temu's multi-SKU one box shipping process can be summarized as follows:

1. **Add to the shipping platform**: Merchants need to add orders to the shipping platform, which is equivalent to grabbing storage capacity. After adding to the shipping platform, the order can be shipped normally. If the order is removed from the shipping platform, it may not be shipped due to insufficient warehouse capacity.

2. **Create a delivery note**: When creating a delivery note, merchants need to confirm the number of packages and the number of shipments. At this time, there is no need to fill in the shipping method and logistics information. After creating the delivery note, the system will automatically process this information.

3. **Print product packaging labels**: Before shipping, merchants need to print product packaging labels and paste them on the corresponding packages. If a label containing logistics information is required, the merchant should select the "ship first and then print" option. After packing and shipping, print it under the "wait for warehouse receipt" menu. At this time, the printed label will contain logistics information.

4. **Bulk delivery/packing delivery**: For delivery orders under the old process, merchants need to select "bulk delivery"; for delivery orders under the new process, merchants need to select "bulk packing delivery", and select the delivery method, number of packings and logistics information.

5. **Express collection**: After completing the packaging, the merchant waits for express companies such as SF Express or ZTO to collect the goods.

6. **Notes**: If a box contains multiple SKUs, a delivery note needs to be affixed to each SKU; if there is only one SKU in the box, only the delivery note needs to be affixed to the outside.

Please note that the specific operation details may change, and merchants should follow the official operation guide tutorial provided by the Temu platform. At the same time, the Temu platform may adjust the process according to the operating conditions, and merchants should pay attention to the platform's update notifications in a timely manner.
