As an artistic carrier, perfume bottles are also the protection of precious perfumes. The quality of perfume glass bottles has a great impact on the preservation of perfumes, the experience of using them, and the reputation of the brand.   Material inspection (IQC)： First, the chemical composition of the glass material needs to be tested to ensure its high purity and the absence of harmful impurities, which directly affects the chemical stability of the bottle and prevents it from reacting with the perfume.Secondly, check the color, cleanliness and uniformity of the glass material. Any defects may cause bubbles, stones or streaks in the final product, affecting its appearance and strength.Inspect glass blanks, plastic particles, metal ingots, electroplated parts, seals, nozzle assemblies, etc.   Process Inspection (IPQC): During the glass melting and forming process, parameters such as temperature and pressure need to be monitored in real time to ensure process stability.The ...

Many brand customers may not realize that the mirror-like glass surface actually hides the challenge of ink adhesion.To solve the above problems and ensure that the brand logo and exquisite patterns can be presented on the skin care glass bottles in a durable and vivid manner, we must pre-treat the glass surface. The following are several methods commonly used in the industry: 1.Why is it difficult for ink to adhere to glass bottles of skin care products? Glass is primarily composed of silicon dioxide (SiO₂), which has a unique structure: silicon atoms (Si) are primarily located within the glass, while oxygen atoms (O) are more exposed on the surface. This structure results in an extremely high surface energy, making the glass highly reactive and easily interacting with surrounding materials. This structure has a high surface energy and is easily interacted with other substances. For example, when exposed to air, it combines with hydrogen in the air to form hydrophilic groups. These hy...

When choosing skincare product packaging, the key differences between UV-protective glass bottles and ordinary glass bottles are mainly reflected in the following aspects: In terms of protection, UV-protective glass bottles can block more than 99.5% of ultraviolet rays (380-500nm band), effectively protecting photosensitive ingredients such as vitamin C and retinol from photo-oxidation; while ordinary glass bottles have almost no professional ultraviolet protection capabilities (blocking rate <50%). In terms of product lifespan and cost, UV-resistant glass bottles can extend product shelf life by 40%-60%, but due to the addition of special oxides, the material cost is 15%-25% higher than that of ordinary glass bottles. In terms of sustainability, both types of glass bottles are 100% recyclable, but the UV-resistant glass bottle can be combined with PCR recycled materials, making it more environmentally friendly. 1.UV Blocking Mechanism:  UV-protective glass bottles form a stabl...
