High GSM Kraft Corrugated Liner Sheet

Description

1. Product Overview

High GSM Kraft Corrugated Liner Sheet is a premium-strength paperboard material engineered for the outer and inner layers of corrugated packaging systems requiring superior durability and load-bearing performance. Manufactured from high-quality kraft paper fibers, it provides excellent stacking strength, puncture resistance, and protection for heavy-duty packaging applications across industrial supply chains. Its enhanced GSM structure delivers improved mechanical performance, making it a preferred solution for export packaging, logistics, and demanding transportation environments. As global industries increasingly prioritize reliable, sustainable packaging solutions, high GSM kraft liners serve as a strategic material for replacing less durable packaging options while supporting recyclable packaging initiatives.
