Paper plastic cup and production technology thereof

The invention discloses a paper plastic cup and a production technology thereof. The paper plastic cup orderly comprises a plastic layer, a printing ink layer, a paper layer and an inner plastic cup layer from inside to outside. The paper layer and the inner plastic cup layer are bonded by multiple binder points. The thickness of the plastic layer is in a range of 8-12 micrometers. The printing ink layer utilizes aqueous printing ink or UV-cured printing ink. The production technology utilizes rolling paper flexible printing, is free of single paper cutting, has a high automation degree and improves production efficiency. Through an extrusion film-formation process, the plastic layer does not contain a binder, a solvent and printing ink peculiar smell so that the fresh milk packaged by the plastic layer has no peculiar smell and satisfies food production safety and health requirements. The paper plastic cup has small thickness, saves raw materials, reduces a cost, saves energy, is environmentally friendly, has no peculiar smell and satisfies food production safety and health requirements.
