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

Different countries and regions have different labeling requirements, covering a wide range of content. For example, in the food industry, China’s General Rules for the Labeling of Prepackaged Foods (GB 7718) requires labels to include product name, list of ingredients, net content and specifications, name, address, and contact details of the manufacturer and/or distributor, production

(1) Fragile Paper: Naturally Weak Fiber StructureFragile paper is the most commonly used material in destructible stickers. Its destructibility comes from its short plant fibers arranged irregularly and weak internal bonding. Composition & Structure:Made from short wood pulp or grass pulp fibers (0.5–2mm, much shorter than standard paper), bonded with minimal plant-based glue (only 1/3–1/5

Colors should also work well with the round shape. Bright colors can stand out, but it’s important to make smooth transitions at the edges. If the sticker is going on a dark surface, using white ink underneath helps the design show clearly. On light surfaces, gradient colors add depth.For example, beauty brands often use pink-to-white

Outdoor use (like building walls or cars): needs to resist UV rays, rain, and temperature changes. Bathrooms: needs to resist moisture, heat, mold, and cleaning chemicals. Industrial machines: must handle oil, chemicals, and rubbing. Food packaging: needs to be eco-friendly and work in cold temperatures. Main needs include: Long-lasting waterproofing – Stickers should stay in

(2) Potential Risks of Additives and Allergy HazardsSupplements often contain various additives, some of which may pose health risks. Artificial sweeteners like aspartame, while satisfying sweetness preferences, have been linked to migraines and gut microbiota imbalance in some studies. Preservatives such as sodium benzoate may react with vitamin C under certain conditions to form benzene,
