Product Features
2.1 Exceptional Durability
High Stiffness: Engineered with precision, this greyboard paper exhibits a remarkable bending resistance surpassing 120 mn. This inherent strength enables it to endure the rigors of handling and transportation, ensuring that the packaged items remain safeguarded during transit. Whether it's protecting delicate jewelry or fragile consumer goods, the high stiffness of JINQIAO greyboard paper provides reliable protection.
Moisture Resistance: Optionally, a water - based PE coating can be applied to enhance its resistance to humidity. This feature is particularly crucial for industries such as jewelry, where gemstones and metal finishes need to be shielded from the deleterious effects of moisture. By preventing the absorption of moisture, the greyboard paper helps maintain the integrity and luster of the products within.
2.2 Printability and Aesthetics
Smooth Surface: The coated top layer of the greyboard paper is designed to achieve an impressive 95% ink absorption uniformity. This smooth surface finish serves as an ideal canvas for printing, enabling the creation of vibrant, high - definition prints. Logos, intricate patterns, and detailed graphics can be reproduced with exceptional clarity, enhancing the visual appeal of the packaging.
Custom Finishes: To meet the demands of luxury and high - end branding, JINQIAO greyboard paper supports a variety of custom finishes. Foil stamping, available in gold, silver, and other metallic hues, adds a touch of opulence and elegance.
