What are the possible causes of color variation and coating peeling in packaging production?
Color variation primarily stems from batch differences in raw materials (e.g., color fluctuations in plastic pellets), unstable injection/blow molding process parameters (temperature and pressure variations), and surface treatment deviations
Color variation primarily stems from batch differences in raw materials (e.g., color fluctuations in plastic pellets), unstable injection/blow molding process parameters (temperature and pressure variations), and surface treatment deviations. Solutions require strict consistency in raw material batches, implementation of automated color matching systems, and regular calibration of all testing equipment. Coating defects often stem from inadequate pretreatment (e.g., residual oil contamination on steel surfaces), incompatible coatings with substrates (e.g., UV paints incompatible with acrylic bottles), or insufficient curing parameters (insufficient UV light intensity). Solutions include modernizing pretreatment processes (e.g., micro-ion cleaning methods), selecting specialized coatings based on substrate properties, and strictly adhering to curing process standards.

The choice of packaging must align with the nature of the contents and the usage scenario: for example, serums, toners, and other liquid products. For products containing active ingredients (e.g., vitamin C, retinol), prioritize opaque glass bottles (UV protection) + vacuum pump caps (air-tight) to prevent oxidation.
