Question: How to select suitable packaging materials and structures based on the characteristics of cosmetics, such as essence, face cream, and perfume?
Answer: It is necessary to match the properties of the content with the usage scenario: for liquid products such as essence and toner, if they contain active ingredients (such as vitamin C, retinol), brown glass or opaque plastic bottles (UV protection) + vacuum pump head (air isolation) are preferred to prevent component oxidation; for creams and other pastes
Body products are suitable for wide-mouth glass bottles or acrylic bottles, with screw cap + inner cap sealing (to prevent moisture evaporation). The bottle mouth diameter is recommended to be ≥38mm for easy access; perfume contains volatile ingredients such as alcohol, so it needs to be made of glass material (to prevent infiltration), with a spray pump head (good atomization effect), and
The sealing integrity of the bottle body must pass a negative pressure test (no leakage after being inverted for 24 hours). Additionally, to avoid material swelling, it is recommended to avoid using ordinary plastic bottles for oil products, and instead opt for HDPE material or glass.
Q: What are the possible reasons for issues such as color difference and coating peeling in packaging production?
Answer: Color differences are primarily caused by batch variations in raw materials (such as color fluctuations in plastic particles), instability in injection molding/blow molding process parameters (changes in temperature and pressure), and deviations in paint ratio during surface treatment. To address these issues, it is necessary to strictly control the consistency of raw material batches, adopt an automatic color matching system, and conduct regular calibration and testing
Equipment; coating peeling is often caused by inadequate pretreatment (oil stains on the bottle surface not removed), mismatch between the coating and the substrate (such as using incompatible UV paint on acrylic bottles), and insufficient curing parameters (insufficient UV light intensity). It is necessary to optimize the pretreatment process (by adding plasma cleaning) and select the coating based on the substrate
Specialized coatings are strictly adhered to the curing process standards.
Q: Will sustainable packaging materials affect product performance or increase costs? How to balance environmental protection and economic efficiency?
Answer: High-quality sustainable materials (such as high-proportion PCR recycled plastics, biobased materials) have been optimized through technology, and their performance can be comparable to that of virgin materials, without affecting the sealing and corrosion resistance of packaging; however, the initial procurement cost may be 5%-15% higher than that of traditional materials. Balancing environmental protection and economic efficiency is crucial
Method: Prioritize the use of recycled materials for the outer packaging (paper box, handbag) that does not come into contact with the contents; adopt modular design to make packaging components reusable (such as replacing the inner core of a makeup brush handle); reduce the unit cost of sustainable materials through large-scale procurement; and incorporate environmental attributes as a brand enhancement
Value proposition: Covering costs through product premium. As technology matures and supply chains improve, the cost advantage of sustainable packaging will gradually emerge.
