Foil, blister, and matte: matching LOCOER 800–820 to the finishing step

Name the finishing step before the grade

A folding-carton coater often keeps one aqueous drum and runs every job through it. Foil then lifts, blister film will not seal, or a matte panel looks glossy. The LOCOER table splits those jobs across 800–820.

The table and Honglu water-based varnish are both quoted from Hefei. Oil gloss and matte OPV on the ink page are a different product from this aqueous list.

• Say in-line or off-line before you ask for a number.
• Say gloss, matte, foil, blister, anti-slip, or two-side rub.
• 818D is the in-line ultra-gloss high-rub grade, not the foil grade and not the blister grade.
• 819 is the blister line. 820 is an aqueous UV primer. They are not substitutes.
• Honglu aqueous is the own-brand option for gloss or matte carton work. It does not inherit an 818D lab figure.

What the table is for

Catalog use, in short: 800 off-line wear and gloss; 810 in-line general, wear, foil, and gloss; 811 anti-slip; 812 smooth high-rub; 814 two-side wear; 815–816 full and half matte; 817 off-line calender; 818 and 818A ultra-gloss wear; 818B ultrasonic; 818D; 819 blister; 820 aqueous UV primer.

Those words are the maker’s sorting labels. Gloss, rub cycles, viscosity, solids, dry, and pH on the sheet are laboratory typicals. Two public notes on 818D already disagree: the table’s gloss about 65–75 and A4 rub about 1000–1500 cycles at 4 lb and speed 2, versus an exhibition line of rub up to 1500 cycles and gloss 80. Different lab conditions. Neither line is your coater’s contract.

When Honglu aqueous is the quote

Use Honglu water-based varnish when the buyer wants HuiRun’s own brand on folding carton or commercial sheets, in-line or off-line, gloss or matte. Coat weight, IR or hot air, and the ink underneath still decide mottle, powdering, and blocking. We quote the TDS window, not a HuiRun laboratory pH.

If the next step is foil or blister, do not default Honglu gloss or 818D. Ask for the foil or the film and point at the catalog grade whose label matches that step, then trial.

What to send with the inquiry

Coater type, in-line or off-line, board, the ink already on the sheet, the finishing step, and kilos. We will name one grade, say whether it is Hefei stock or a factory slot, and attach that grade’s TDS. A sentence that only says “water-based varnish” waits.

What the quote covers

We will not promise foil release, blister peel, or a rub count because a catalog cell sits next to a number. The trial on your coater, your foil or film, and your board is the record. Related notes this week cover foil failure, blister grades, and how to write the acceptance line.
