Is the word sacola the same in Brazilian and European Portuguese?

No

While the word "sacola" is understood in Portugal, there is a difference in typical usage. In Brazil, "sacola" is the standard, everyday word for a plastic or paper shopping bag. In Portugal, the word "saco" is much more common and natural for this purpose. While a Portuguese person might use "sacola" to refer to a larger tote bag or a specific type of handbag, they will almost always use "saco" when referring to a bag used for groceries or carrying small items.

Brazilian Portuguese Examples

1. Eu esqueci a minha sacola no supermercado. (I forgot my bag at the supermarket.)
2. Você pode me dar uma sacola a mais, por favor? (Can you give me one extra bag, please?)
3. Esta sacola de papel é muito resistente. (This paper bag is very strong.)
4. Coloque as frutas dentro da sacola. (Put the fruits inside the bag.)
5. A sacola de plástico rasgou no meio do caminho. (The plastic bag tore halfway there.)
