Liquid Packaging Board (LPB) is a multi-layer, liquid-coated paperboard designed for packaging applications. Made with a three-layer (surface-core-bottom) structure, it delivers strong water resistance, anti-edge seepage, and robust bonding between paper and plastic film.
LPB excels in food and beverage packaging, combining eco-friendliness (reduced chemical use) and cost efficiency with reliable structural performance. It suits dry food, liquid-containing goods, and daily necessities.
Golden Paper offers a versatile LPB lineup, featuring high physical strength, excellent printability, and food-safe compliance. Its variants cater to diverse needs for durability, decorative effects, and safety standards in packaging.

Liquid packaging paper (LPB) is designed for long-term storage of liquids like milk or juice, requiring a multi-layer structure with a strong barrier against oxygen and moisture. In contrast, cupstock paper is primarily for single-use cups and bowls, relying on a smooth, PE-coated surface for basic liquid resistance and formability.
The shelf life primarily depends on the product itself and the filling process, but our LPB provides excellent protection against moisture and light, helping to extend the product's freshness.
Absolutely—LPB has a smooth, coated surface that enables exceptional print quality, including vibrant colors and fine details for brand differentiation.
Yes, LPB is widely recyclable. It is typically collected with mixed paper and recycled into new paper products, contributing to a circular economy.
we are committed to providing the most suitable solutions and reliable products!
