The invention belongs to the technical field of composite food packaging materials, and discloses a graphene/polyolefin plastic composite food packaging film, a preparation method and application thereof. The graphene/polyolefin plastic composite food packaging film of the present invention contains 0.02 to 2 wt% of graphene. The invention also provides a method for producing the above-mentioned film. The graphene/polyolefin plastic composite food packaging film of the invention improves the performance of the plastic film for food packaging, and has excellent mechanical properties by adding a small amount of graphene. The graphene in the graphene/polyolefin plastic composite food packaging film of the invention can effectively inhibit the migration of the plastic auxiliary to the food and food simulant, which is important for the safety of the consumers and the graphene/polyolefin plastic composite food packaging film can be widely used in food and other fields. 本发明属于复合食品包装材料技术领域，公开了种石墨烯/聚烯烃塑料复合食品包装薄膜及其制备方法和
