Characteristics of Liquid Packaging Board

Liquid packaging board is a food-grade paper and a requirement for long-term storage of liquids. One of its core characteristics is good barrier properties, which can prevent oxygen from entering and causing oxidation, deterioration, nutrient loss, and microbial growth of the contents.

Good physical and mechanical properties. It has sufficient tensile strength, tear strength and burst resistance to withstand the pressure of filling, transportation, and stacking to prevent breakage.

Printing adaptability. The outer surface must be able to print patterns with high quality, good whiteness, smoothness and ink absorption.

Heat sealing performance. During filling, the inner heat sealing material needs to be perfectly matched with the filling machine to ensure a firm seal without penetration.

Application of Liquid Packaging Board

Dairy product packaging. It can be used for packaging room temperature milk, yogurt and fermented milk. It is suitable for high penetration resistance and acid resistance occasions.

Juice and plant milk packaging. Acidic juice requires corrosion-resistant materials, suitable for occasions that need to prevent oxygen penetration and portability.

Medicines and health drinks. Ensure that there is no microbial contamination through a strict aseptic production environment. The packaging of energy drinks and protein drinks needs to block oxygen and preserve fragrance, and the aluminum foil layer of liquid packaging board can effectively lock in the active ingredients.
