每份 is a pronoun-like expression combining 每 ('each, every') with the measure word 份 (for portions, copies, servings, etc.). It refers to 'each portion' or 'every copy' of something that is counted in 份 — such as servings of food, copies of a document, or individual items in a set. You can use it as a subject or object to talk about each individual unit in a group.
