Q: How do HCOLOR courier bag water-based inks achieve high opacity and adhesion over dark recycled PE films?

We utilize surface-treated rutile titanium dioxide with a high refractive index and specialized adhesion-promoting acrylic polymers. This delivers high covering power over dark grey or black co-extruded films in a single pass while maintaining over 98% adhesion under 3M 610 tape cross-hatch peel testing.

Q: Can these inks prevent smearing and barcode illegibility during automated conveyor sorting?

Yes. Our WLF90000 and WPG-B30000 formulations incorporate micronized polyethylene and PTFE slip additives that form a dense, low-friction surface film upon drying (dynamic COF ≤ 0.25). Barcodes and QR codes withstand repeated sliding across automated sorting conveyor chutes without scuffing or loss of scan contrast.

Q: How does switching from solvent to water-based inks benefit courier bag converters?

Converters eliminate the fire hazards and expensive explosion-proof infrastructure required for solvent facilities, significantly reducing insurance and environmental compliance costs. Factory air quality is dramatically enhanced, and finished mailers comply fully with green postal procurement guidelines (e.g. SF Express and China Post standards).

Modern e-commerce and logistics packaging experiences extreme mechanical abrasion, multi-node transit handling, and high-speed automated hub sorting. Packaging must maintain barcode readability, brand graphics, and tear resistance under all weather conditions.

HCOLOR delivers high-coverage, rapid-drying water-based gravure inks for multi-layer co-extruded PE/PO courier bags (such as SF Express and Vipshop mailers) and fast-drying flexo inks for pre-print and post-print corrugated shipping containers.

Our solutions eliminate flammable solvent emissions in high-volume production facilities, providing exceptional slip, anti-blocking, and high optical opacity on recycled or dark polymer backings.
