30ml Serum Bottle（JH-179G）
This 30ml flat square cosmetic bottle adopts a modern and streamlined flat square silhouette with neat and smooth body lines, breaking the monotony of conventional round bottles. The ergonomically optimized flat body delivers a comfortable and non-slip grip, bringing a delicate and solid hand-feeling during daily use and product application. With a moderate 30ml capacity, this versatile container is perfectly tailored for high-end skincare liquids, including facial essences, plant essential oils, concentrated serums and other premium cosmetic formulations. It is widely applicable for official product launch, brand retail, private label customization and daily portable storage, featuring a minimalist and advanced aesthetic that fits diverse modern skincare brand styles.
The bottle is equipped with a premium 20-thread high-grade PETG middle collar assembly, upgrading the overall packaging texture and structural stability. Made of high-quality PETG material, the middle collar boasts high light transmittance, excellent toughness, scratch resistance and anti-aging properties, maintaining a crystal-clear and glossy appearance for a long time. Compared with ordinary plastic accessories, PETG material features stable chemical performance, tight thread matching and firm assembly, effectively avoiding loosening, shaking or structural damage during long-distance transportation and repeated daily use.
Matched with durable silicone rubber cap, standard 7mm low-borosilicate round-head glass tube and 20# PE guide plug, the complete accessory set builds a highly airtight and leakproof sealing system. The flexible silicone rubber cap provides superior fitting and sealing performance, which can effectively isolate external air, dust and moisture, prevent internal skincare liquids from volatilization, oxidation and deterioration, and fully lock the active ingredients of essences and essential oils. The low-borosilicate glass tube owns stable chemical inertness, which will not react with delicate cosmetic ingredients, ensuring safe, clean and hygienic liquid extraction every time.
With precise liquid output control, this bottle effectively avoids raw material waste and brings users a convenient and labor-saving using experience. Exquisitely crafted with safe and reliable materials, it balances fashionable flat square appearance and practical functional performance. In addition, there are clear customization specifications for accessories: the minimum order quantity for electroplated rubber caps and special-color rubber caps is 50,000 pieces respectively. Overall, this 30ml bottle is a cost-effective and professional packaging solution for high-end cosmetic wholesale and brand customized packaging.
