Paper is strong and durable: Book cover paper must possess high toughness and strength to protect the inner pages. It is abrasion-resistant and fold-resistant, capable of withstanding daily use such as flipping, folding, and friction without tearing easily.
Waterproof and moisture-resistant: Some book cover papers offer water resistance, effectively blocking moisture penetration to prevent the cover from dampening or molding. Even if accidentally splashed with water, it provides a degree of protection for the book.
Diverse and eco-friendly materials: Book cover paper comes in paper and plastic varieties. Paper covers are primarily made from strong, resilient materials like chemical wood pulp, with some incorporating grass fibers and recycled paper pulp. Plastic covers predominantly use environmentally friendly, non-toxic materials to ensure safety and health during use.
