label

Transparency and Clarity:Labels must clearly display printed information such as serial numbers, QR codes, and warnings. Key indicators include: Light transmittance: Should be ≥85% to ensure readability. Haze: Should be ≤3%; excessive haze can scatter light and make QR codes unscannable, reducing logistics efficiency. Mechanical Strength:To resist damage and tampering, the material must: Have tensile

Functional Compression of Graphic Symbols:Superfluous decorations are avoided, with only essential visual identifiers retained. For example, the dermocosmetic brand Eucerin features a monochrome gradient background with abstract “skin cell” line illustrations serving as visual anchors. This reflects its “medical skincare” positioning without compromising the readability of ingredient information. Graphic elements are strictly limited to 15%-20%

I. Performance-Driven Selection: Heat and Wax Resistance Are KeyCandles release heat during use (typically 50–80°C), and melted wax may come into contact with the sticker surface. Therefore, thermal stability and resistance to wax/oil are the primary criteria for material selection. Heat Resistance and Chemical Stability:With a melting point of around 80–100°C, vinyl can withstand the
