I. Core Selection Principles: Safety First, Functional Fit When selecting label materials for beverage-type health products, the foremost requirement is “food-contact safety.” The material must then be compatible with the product’s full life cycle, ultimately achieving a balance among safety, functionality, and cost. All three principles are essential: (1) Food-Contact Safety Principle Because labels directly

I. Authority Certifications: The Visual Anchor of Compliance and Premium Positioning Authoritative certifications are the most direct form of quality endorsement in wine design. The core principle is “highlight the essentials, present them correctly, and reinforce them visually,” ensuring consumers immediately recognize the wine’s legitimacy and premium credentials. Wine certifications generally fall into two categories:

Material selection is the core of micro–nano stickers used in wearable devices. The materials must simultaneously provide flexibility, biocompatibility, and functional specificity—solving the conflict between “rigid functions” and “flexible substrates.” The substrate layer, which directly contacts the skin, requires ultra-thinness, high elasticity, and breathability to achieve ergonomic, skin-friendly, and form-fitting performance. Silicone-based materials such as

I. Core Principles for Material Selection: “Medical-Grade Safety” as the Fundamental Logic Material selection for photopolymer stickers in the medical industry must go beyond the basic needs of “appearance and adhesion.” It must strictly follow a safety-first, performance-matched, and compliance-traceable logic. Three core principles are indispensable: Materials must comply with biocompatibility requirements and avoid releasing
