Identify the film and printing side
Share the film type, supplier or grade, lot, thickness if known, treated side, treatment age or available test data, and whether the sample is plain, coated, or already printed.
Selected film converter route
Application
Support for selected flexible packaging film projects where converters want to evaluate water-based ink alternatives under real press and substrate conditions.
Application fit
Begin with material, print process, handling requirement, and the issue that needs checking. Application pages are not a guarantee that every substrate, structure, or end use is already approved.
JLJ Coating can discuss water-based ink and varnish options for this application when the buyer provides substrate details, printing process, current issue, and target property. The most useful sample conversations include real substrate or printed samples.
Buyer short answer
Flexible packaging is a selected-trial route, not a blanket compatibility claim. The first review should identify the film, printing side, treatment condition, ink process, dryer capacity, and every downstream layer or test.
Share the film type, supplier or grade, lot, thickness if known, treated side, treatment age or available test data, and whether the sample is plain, coated, or already printed.
State the cylinder, metering setup, line speed, ink-film direction, and dryer capacity. A result on one film, treatment level, or structure should not be treated as proof for another.
Record when adhesion, blocking, transfer, or drying fails, how the sample was conditioned, which test method was used, and whether the failure appears before or after rewinding, lamination, packing, or another downstream step.
Provide the underlying and subsequent layers, print or lamination sequence, end-use handling, and acceptable reference. Compatibility and regulated-use claims require exact product documents and real structure testing.

FAQ
The team can assist with selected film evaluations. Suitability depends on substrate, surface treatment, drying, print structure, and trial results.
No. Film compatibility should be checked case by case. A trial with the actual film and process is needed before production decisions.
Film type, treatment level, line speed, dryer setup, adhesion requirement, downstream lamination or packing process, and target performance should be shared.
A clear inquiry should include substrate type, print method, current ink or varnish issue, performance target, and any downstream converting requirement.
