What is paper cup base paper

2025-11-10

Paper cup base paper is a type of paper specifically used for making paper cups, usually processed from white cardboard made from chemical wood pulp.
Paper cup base paper is a substrate paper specifically designed for making disposable paper cups, and its design and processing must meet food safety, waterproof and oil resistant, and molding requirements.
The above are the answers given by two AI software. In summary, paper cup base paper is a specific material used to make paper cups, which meets the product's usage requirements, namely food grade, safety, waterproof and oil resistant. The key processing techniques focus on introducing coating technology:
PE coating: a mainstream process that uses extrusion coating to composite polyethylene film (thickness 15-30 μ m) onto paper surface, providing waterproof and oil resistant functions. Hot drink cups are made of high-density PE (temperature resistance above 90 ℃), while cold drink cups are made of low-density PE.
PLA coating: Biodegradable polylactic acid coating, suitable for environmentally friendly paper cups, with a temperature resistance of about 50 ℃.
Water based coating: an emerging fluorine free waterproof treatment that meets stricter environmental standards.
Our paper cup base is made of PLA coated PLA film paper, which produces PLA paper cups. Compared with traditional paper cups, it has biodegradable properties and safe and non-toxic functions, making it safe to use. If users need to purchase paper cup base paper, they can choose PLA coated paper. Polylactic acid (PLA) coated paper is processed and produced using pure PLA raw materials, with 100% bio based and no other additives. The product has passed FDA certification, European DIN biodegradable certification, US BPI certification, Australian ABA biodegradable certification, and food grade certification. In daily life, PLA coated paper can be widely used to make various types of products, such as cold (hot) beverage cups, coffee cups, soup bowls, paper plates, meal boxes, and food packaging products. It can also meet the paper packaging needs of various fields such as daily chemical products, electronic products, medical, agricultural, and industrial products.
