Sinbottle guides clients through selecting glass bottles for cosmetics with a systematic evaluation framework. Start by defining product needs: light-sensitive formulas require amber/blue glass; viscous products need wide-neck bottles for easy dispensing. Consider brand positioning: luxury brands may opt for thick-walled frosted glass with gold accents, while eco-brands prefer recycled glass with bamboo lids. Evaluate functional features: airless pumps for anti-oxidation, droppers for precision, or sprayers for even application. Technical considerations include: 1) Compatibility with filling equipment; 2) Labeling surface area; 3) Transport durability (stackable designs, shock-resistant packaging). Sinbottle’s design team provides 3D renderings and physical samples to visualize how bottle choices align with product formulation, brand identity, and user experience.
