Its metallic sheen and dynamic light reflection can capture a consumer’s attention in just 0.1 seconds. Whether used for premium gift bags in export markets or local FMCG packaging, the right stamping choice can directly impact product premium and market competitiveness. This article offers a deep dive into fabric compatibility, technical parameters, and quality control—revealing how to use hot stamping to achieve a “low cost, high value” brand upgrade strategy.
How Does Foil Stamping Work?
(Understand production in just 3 simple steps)
Step 1: Choosing the Right Material
- Polyester: Best for glossy gold foil, vibrant and clean finish
- Cotton & Linen: Matte silver recommended to avoid awkward glare
- Waterproof Coated Fabric: Requires surface treatment (technical term: medium isolation)

Step 3: Temperature Control
- General Use: Iron temperature ~140°C (feels warm over the hand)
- Detailed Patterns: Heat to 160°C + apply pressure for 3 seconds (stamp-like effect)
Step 4: Final Inspection

- Rub with fingertip 10 times—no color loss
- Hold up to light—check for bubbles, missing edges
Cost Control Formula
- Foil stamping unit price = base ¥0.8 + specialty foil surcharge + labor loss
- Example: 10 cm² logo = ¥0.8 + ¥0.3 (special foil) + ¥0.2 = ¥1.3 per piece
