Cleaning cosmetic glass dropper bottles properly is key to keeping your serums, essential oils, and liquids free from contamination. Follow this quick 4-step process to ensure they’re spotless and safe for reuse. ​ First, disassemble the glass dropper bottle—separate the rubber bulb, glass pipette, and bottle itself. Fill a bowl with warm (not hot) water and let all parts soak for 10–15 minutes. This loosens residue, oils, or dried liquids clinging to the surfaces, making them easier to clean.​ Next, disinfect with rubbing alcohol (70% isopropyl works best). Either submerge all components in alcohol for 5 minutes, or pour alcohol into the bottle and squeeze the bulb repeatedly to flush the tube thoroughly. Alcohol effectively kills bacteria and breaks down tough, stubborn grime that plain water would likely leave behind. ​ After alcohol treatment, rinse all components with warm water to remove any alcohol residue. Then, air-dry them completely on a clean towel—l...

 Jars： Glass Jar (Heavy, Luxury, and Temperature-Resistant) Glass Jar come in a variety of formats, including jars, bottles, and vials, making them ideal for products requiring the utmost purity. Amber or frosted glass variants offer UV protection, protecting light-sensitive ingredients like retinol or vitamin C from degradation. Plastics Jar (such as PETG, ABS, and PP, which are lightweight and easy to process) are widely valued for their durability and cost-effectiveness. High-density polyethylene (HDPE) and polypropylene (PP) are common choices, offering chemical resistance and lightweight advantages. Plastic jars with screw-top lids are suitable for body butters and thicker lotions. Features: Classic and traditional, easy to use, and easy to show the paste texture and color. However, the contents are frequently in contact with air and fingers, which requires a high level of antiseptic system. Applicable to: Luxurious nourishing facial creams, sleeping masks, massage creams, ne...

For skincare brands, the texture and quality of glass bottles directly impact product premiums, and the manufacturing process is crucial to determining quality. Currently, mainstream glass bottle manufacturing processes primarily focus on blowing, tubing, and drawing. Different processes correspond to different product characteristics, necessitating distinct considerations when selecting suppliers. 1.The blowing process is an excellent representative of high-end skin care glass bottles. The blowing process is mainly used to manufacture bottles with complex shapes, thick walls, and high-end appearance. It is especially suitable for customized bottles, such as irregular essential oil bottles and retro cream jars. When selecting a blow-molded bottle supplier, focus on three key aspects: Mold development capabilities. A good supplier should possess independent mold design and processing capabilities, accurately reproducing details such as bottle body texture and bottle neck curvature based...

I.Color: Slight color deviation from the Pantone color chart will be determined based on the Pantone color chart. II.Finished Product Defects：Mold line misalignment is noticeable and can cause hand injuries. III. Common Appearance Defects: Cracks, chips, chipped corners, deformation, glass ripping, internal wall sticking, and sharp punctures that may affect the seal and pose a risk of injury. Cold marks, pitting, brush marks, wrinkles, stubble marks, scissor marks, base thickness variations, and minor scratches may also be present on the bottle. Discoloration, black spots, bubbles, and pinholes may be present elsewhere. IV.Foreign Objects: Broken glass, insects, metal, blood, and other issues. Check the bottle's interior and exterior for visible foreign objects such as oil, water, paper scraps, and small impurities. V. Process Spraying The sprayed surface is not smooth or flat; it may exhibit streaks, wrinkles, frosting, orange peel, or other defects. On the main viewing surface: Two p...

Test focus: Chemical Resistance: Products containing strong acids or bases, particularly those containing strong acids or bases, may corrode the glass surface. This corrosion may cause glass flakes to break off, form visible particles, or imperceptibly damage the integrity of the glass. Furthermore, these substances can dissolve alkali metal ions. If these ions accumulate on or within the glass, they can cause a dramatic shift in the glass's pH, altering its chemical properties and ultimately affecting its performance and lifespan. Inner layer surface treatment: whether the release agent, siliconizing agent or other inner coating is compatible with the contents, whether it migrates or affects the stability of the contents. Metal Cap/Pump Head Compatibility: While glass itself is inert, the accompanying metal cap (available in tinplate or aluminum) and pump head (made from various types of plastic and metal springs) must be compatible with the contents. This is because corrosion and rus...

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...

Packaging design plays a crucial role in consumers' purchasing decisions and can be regarded as the "make-or-break point" for brands to impress consumers. As Gen Z gradually becomes the main consumer group, experiential packaging has become the core track for brand competition. With its natural texture and strong plasticity, glass bottles are emerging as a key carrier for brands to capture consumers' minds. Has your brand seized the opportunity in this experiential competition by leveraging glass bottle packaging?   Nowadays, more and more enterprises regard customer experience as their core competitiveness, and its importance has surpassed traditional differentiators such as price and functions. For glass bottles, experiential design transforms them from mere product containers into media that create dynamic and unforgettable multi-sensory experiences for consumers. This perfectly aligns with Gen Z's consumption preferences—they value the self-expression and emotional conne...
