White Top Liner/board (WTL) is a type of packaging material that consists of multiple layers. It features a white printing surface on top of a kraft base sheet. The white top is specifically designed to provide a smooth and bright surface, making it ideal for high-quality, multicolor graphics commonly found in retail-ready corrugated consumer packaging.

Certainly! Here are some additional details about White Top Linerboard (WTL):

Applications: WTL is commonly used in the production of various types of packaging, including corrugated boxes, folding cartons, displays, and other retail-ready packaging solutions. It is particularly suitable for packaging that requires high-quality printing and attractive graphics.

Coating: The white top surface of the linerboard is typically achieved through a coating process. The coating material used is designed to enhance the printability and brightness of the surface, allowing for sharp and vibrant colors in printed designs.

Thickness and Basis Weight: WTL is available in different thicknesses and basis weights to meet specific packaging requirements. The thickness of the linerboard affects its strength and rigidity, while the basis weight refers to the weight of a given area of the material (usually expressed in grams per square meter or pounds per thousand square feet).
