Black in packaging is not a style decision; in thermoformed liners it is a material decision. The carbon black that colours the sheet also screens UV, tames static in conductive grades, and hides the grease film a liner picks up in its first month on the line. For liners expected to run for years in a warehouse or a yard, black is usually the correct specification.
Carbon black does three jobs
UV screening: unstabilised PP chalks and embrittles within a season of yard duty; a two percent carbon black loading pushes that failure far beyond the service plan. Grease tolerance: a black surface keeps its appearance between wash cycles, so supervisors can judge cleanliness by sheen rather than stains. Static control: carbon-loaded compounds bring surface resistance into the dissipative range for painted and electronic parts.
Gauge chosen per duty
Liner walls run from 2 mm for light kitting trays to 6 mm for liners that take castings dropped from knee height. The spec sheet for each project states gauge, resin and the test it must pass, so replacement orders arrive identical years later.
Standard black liner formats
BK 1210: 1200 x 1000 mm footprint, 3-5 mm wall, pallet box liner, UV-stabilised PP.
BK 865: 860 x 650 mm footprint, 2.5-4 mm wall, container liner, PP or PE blend.
BK 604: 600 x 400 mm footprint, 2-3 mm wall, tote liner with cutouts to drawing.
BK-C: conductive variant, surface resistance 10^4-10^6 ohm, for painted and electronic parts.
Fit without re-engineering the box
Liners are drawn to the internal dimensions of the container you already run, with cutouts for bolt bosses, sensor windows and label fields. First articles are trial-fitted in your container, and the drawing is locked so replacements drop straight in.
Service documentation
Every batch ships with a material certificate covering resin grade, carbon loading and gauge, plus REACH and ROHS declarations where required, so the liner can be referenced in audit files the same way as the container itself.
Send the container model and the duty the liner must survive, and we will return a gauge and compound recommendation with pricing inside three working days.
