When we use pasty and liquid productions, such as toothpaste shampoo and facial cleaners, we must leave some on the inwall of the packing in the end, which is very wasteful. No left packing has a layer of plastic film attached to the inwall of the packing. After the production used up, you can pull the film out and scrape the left paste off, avoiding waste.
