包裹 (bāoguǒ) means 'to wrap up' or 'a package' — it implies enclosing something inside wrapping, like a gift or parcel. For everyday wrapping (e.g., a gift), 包 (bāo) is shorter and more colloquial; 包装 (bāozhuāng) focuses on commercial packaging; 打包 (dǎbāo) is for packing leftovers or luggage; and 裹 (guǒ) means to wrap tightly around (a scarf, wound).
