Applications of Liner Paper

• Kraft Liner, with its core advantages of high strength, tear resistance and good moisture resistance, is made from unbleached sulfate wood pulp. Its natural brownish color makes it suitable as the outer layer of corrugated boxes. It is widely used in load-bearing packaging such as transport boxes for home appliances and building materials, as well as the outer layer of heavy express delivery boxes. It can also be used as the outer layer of food packaging that meets safety requirements.

• Test Liner, with relatively low strength, is made from waste paper pulp and is more economical in cost. It has a color that is grayish yellow or brown. It is mainly used for the inner layer of corrugated boxes, providing support and isolation functions. It is suitable for light-load packaging such as daily necessities and small commodity packaging boxes, as well as temporary turnover boxes, inner layer spacers and buffer pads, etc.

• White Top Liner has a surface layer of bleached wood pulp that appears white and a bottom layer of waste paper pulp or unbleached pulp. It takes into account both appearance neatness and certain strength. Its core application is the outer layer of corrugated packaging that requires printed patterns, such as food gift boxes, electronic product packaging boxes, and brand-customized cartons. It is also suitable for retail packaging and display corrugated boxes that require a clean appearance. And scenarios such as e-commerce express boxes that require color printing.
