Introduction
In the packaging of milk, juice, plant-based beverages, dairy products, and soups, Liquid Packaging Board (LPB) plays a vital role. It must offer strong resistance to moisture and grease while ensuring high stiffness, food safety, and excellent printability. In this article, we’ll explore what LPB is, how to choose the right type, and why China Paper is your trusted supplier.
What is Liquid Packaging Board?
LPB is a multilayer board specifically designed for liquid food applications. Made from 100% virgin wood pulp, it offers high purity and structural integrity. A layer or dual layers of polyethylene (PE) coating on the surface provide effective water and oil resistance. LPB is widely used for aseptic cartons and other liquid packaging solutions, ensuring that packaging maintains its form and function during filling, sealing, and transport.
How to Choose the Right LPB for Your Application?
1. PE Coating Type
Single-sided PE coating: Ideal for cold beverages and short-shelf-life drinks such as juice or yogurt.
Double-sided PE coating: Recommended for hot beverages, milk, plant-based drinks, or packaging with long storage requirements.
2. Grammage Options
China Paper offers custom LPB from 150gsm to 400gsm, ensuring sufficient stiffness and strength for various carton sizes and formats.
3. Printability
Premium LPB must support excellent print clarity and color vibrancy. Our boards offer smooth surfaces that work well with both offset and flexo printing, making branding easier and more effective.
4. Food Safety Compliance
All China Paper LPB products are ISO 9001, ISO 14001, and FSC certified, with food contact safety guaranteed. Product testing reports are available upon request.
