The quality of cosmetics packaging directly impacts product safety and brand image. Professional manufacturing enterprises ensure that every product meets industry standards and customer requirements through precise manufacturing processes and comprehensive quality control throughout the entire process.
Material selection and pretreatment are the foundation of quality control. Inner packaging materials that come into contact with cosmetic contents (such as bottle bodies and pump heads) strictly adhere to food contact material standards like FDA and EU10/2011. These materials are made from food-grade materials like PET, PP, and acrylic. Each batch undergoes testing for heavy metals and plasticizer migration
Conduct rigorous testing to ensure safety and non-toxicity. The glass material is made of high borosilicate glass, which undergoes annealing treatment to eliminate internal stress, increasing its impact resistance by 20% and preventing breakage during transportation. In the pre-treatment process, damaged plastic bottles undergo sterile cleaning (with a cleanliness level of 100), while glass products undergo high-temperature disinfection, ensuring
Provide clean containers for subsequent filling.
Precision manufacturing processes ensure product consistency. The injection molding process utilizes a fully electric injection molding machine with temperature control accuracy of +0.5℃, ensuring uniform wall thickness of the bottle body (with an error of ≤0.1mm). The blow molding process optimizes mold design through 3D simulation, improving the glossiness of the bottle body by 30% and eliminating defects such as bubbles and scratches.
Precision control is achieved in surface treatment processes: the thickness of the vacuum plating layer is controlled at 5-10μm to ensure uniform metallic texture; the light intensity and time parameters of the UV curing process are digitally managed to ensure that the coating adhesion meets the standard (cross-cut test ≥4B). The automated assembly line employs machine vision inspection for bottle caps
100% inspection is conducted on sealing performance and smoothness of pump head pressing, and non-conforming products are eliminated.
The full-process quality traceability system ensures that issues can be traced and controlled. From raw material storage to finished product delivery, key parameters (such as raw material batch, production time, and test results) are recorded at each stage, and are associated with a unique traceability code. Regular simulated transportation tests (vibration and drop tests) and weather resistance tests are conducted
(High and low temperature cycling, humidity testing) to verify the stability of packaging under extreme conditions. For export products, additional destination standard compliance testing (such as EU REACH regulations, US CPSC standards) is conducted to ensure compliance with local market access requirements.
