Personal Care & Hygiene

Q: How do HCOLOR personal care inks ensure skin safety for baby diapers and feminine hygiene products?

Our WLF-B70000 series is formulated exclusively with medical-grade deionized water and skin-safe acrylic polymers, excluding all phthalate plasticizers, organotin compounds, and biocides. Formulations pass biological cytotoxicity, acute skin irritation, and sensitization evaluations according to GB/T 16886 and ISO 10993 standards.

Q: How does the ink maintain strong adhesion on ultra-thin breathable PE film without causing web distortion?

Breathable PE cast film is heat-sensitive and dimensionally delicate. Our inks are formulated with low-temperature drying resins that cure thoroughly under mild warm-air impingement (50°C–65°C), preventing film shrinkage or pinhole closure while delivering cross-hatch tape adhesion above 95% on corona-treated surfaces (≥38 dynes/cm).

Q: Can these inks resist continuous rubbing from 75% medical alcohol and personal care lotions?

Yes. By incorporating self-crosslinking acrylic functional groups, our WLF and WPG series form a dense, chemically impervious film after drying. Prints easily withstand over 50 mechanical rubs with 75% medical ethanol pads and resist degradation from surfactant-rich wet wipe emulsions without ink bleed or tackiness.

Hygiene and personal care packaging directly touches consumer everyday life. From breathable PE films for baby diapers and feminine care to flexible pouches and squeeze bottles for personal cleansing products, safety, skin compatibility, and low volatility are paramount.

HCOLOR delivers skin-friendly water-based and LED/UV inks with verified resistance to alcohol (75% medical ethanol), cosmetic surfactants, essential oils, and continuous web flexing without flaking or odor bleed.

Our dedicated WLF-B70000 series runs smoothly on high-speed central-impression (CI) flexo presses at 120–180 m/min, providing high opacity, sharp dot definition, and dependable anti-blocking on ultra-thin cast films.
