Unlocking the Aesthetic Secrets of Paper Packaging

Unveiling the Surface Processes of Paper Packaging – Making Packaging “Speak”

Decorative Processes: Creating Visual Focus

1. Hot Stamping: Giving Packaging a “Metallic Coat”

Hot stamping, commonly known as “gold stamping,” transfers aluminum foil onto a substrate under high temperature and pressure, creating a strong metallic luster and adding a high-end feel to the packaging. Besides the common gold, there are also silver, red, and laser gold options, widely used in luxury goods and gift box packaging, making brand logos or designs instantly stand out.

2. Spot UV and Reverse Matte Finish: The Magic of Light and Shadow

Spot UV coating involves applying UV varnish to specific areas, making the graphics and text vibrant, bright, and three-dimensional, like adding a “spotlight” to the packaging. Reverse matte finish creates a contrast between high-gloss and low-gloss areas on the printed surface. Through the chemical reaction of a special base oil and UV varnish, a unique texture contrast is created, suitable for packaging designs that need to highlight key information. 

3. Embossing and Die-cutting: Giving Packaging a "Temperament"

Embossing uses molds to plastically deform paper, creating embossed, three-dimensional textures that enhance tactile and visual appeal. Die-cutting uses steel dies to cut paper into unique shapes, often combined with cutout designs, giving packaging both functionality and artistry; this is commonly seen in creative gift boxes and high-end product packaging. Solvent-free lamination and water-based UV varnishes are gradually replacing traditional technologies, meeting consumers' demand for sustainable packaging.
