“Gold Silver Foil Metallic Paperboard”is a special type of cardboard with a metallic luster such as gold and silver on its surface. It is not made of pure gold or silver, but achieves its unique appearance and performance by compounding or evaporating a very thin layer of metal material(usually aluminum)on the surface of the paper substrate. Common weights include 250gsm,300gsm, 350gsm, 400gsm, and conventional sizes include 787×1092mm, 889×1194mm, 700×1000mm, 1091×788mm, etc. The surface is waterproof and moisture-proof, and some products have high durability.

Manufacturing process

The core of "Gold Silver Foil Metallic Paperboard" lies in the "metallization" treatment, which mainly involves two processes:

Transfer method (composite type): First, a metal layer is evaporated on a PET or other film, then transferred to the surface of cardboard with glue, and finally the film is peeled off. The cardboard produced by this method has a very shiny surface and a strong metallic texture.

Direct coating method: Coating materials containing metal pigments (such as copper powder) directly onto a paper substrate.

Regardless of the process, the core is to give ordinary cardboard a metallic luster and texture, which is used to enhance the quality of packaging and printed materials.

Main Features

Gorgeous appearance: With a strong metallic luster and mirror reflection effect, it has a strong visual impact and can significantly enhance the level of product packaging. Some products also offer various textures such as hairline and water ripple.

Excellent physical properties: It usually has good moisture resistance, waterproofing, high temperature resistance, high stiffness, and is not easily deformed.

Environmental attributes: Most products are recyclable and biodegradable, and belong to environmentally friendly materials.

Printing precautions: The metal coating on its surface does not absorb ink. When printing, special ink should be used, or a layer of white ink should be printed as a base to achieve better color rendering effect.

Main Purpose

With its high-end appearance and good physical properties, this cardboard is widely used:

High end packaging: widely used in gift boxes, cosmetics boxes, food packaging (such as cake trays), pharmaceutical packaging, and tobacco and alcohol packaging.

Craftsmanship and Decoration: Ideal materials for card making, invitations, book binding, paper crafts, and holiday decorations.

Industrial applications: Due to its moisture-proof and heat-insulating properties, it is also used as a backplate material for household appliances such as refrigerators, freezers, and display cabinets.

Overall, Gold Silver Foil Metallic Paperboard is a high-end specialty cardboard that combines a luxurious metallic texture with practical physical properties. It imparts metallic luster to the surface of paper-based materials through transfer or coating processes. It not only has a high-end appearance and strong visual impact, but also has excellent stiffness, moisture resistance, and folding resistance. Most products are recyclable and biodegradable, which is in line with environmental trends. Its application areas span from high-end gifts, cosmetics, tobacco and alcohol packaging, to creative crafts such as greeting cards and book binding, as well as industrial scenarios such as home appliance backboards. In terms of specifications, weights ranging from 120gsm to over 2400gsm and various standard sizes can be flexibly customized to meet personalized needs in different scenarios. In short, this is an ideal packaging material that integrates aesthetic value and functional practicality through technological and material innovation.
