  • Why IML for industrial pails?

    IML fuses the label into the container during moldingreducing peeling and improving scratch/moisture/chemical resistance, which is ideal for harsh industrial handling. 
  • Heat transfer coverage & limitations?

    Pails often have taper, ribs, and handle lugs. For alignment and yield, full-wrap usually needs boundaries—seams/gaps or minor distortion control are common.

    Screen printing typically uses one screen per color; more colors increase setup/registration complexity and costso color count is practically limited.
    Best for logos/text/simple graphics and long-run SKUs.

    Choose by environment resistance, graphic complexity, coverage area, and cost/lead time. IML is known for fused-in durability and strong resistance to scratching/moisture/chemicals. 
  • When is a filter screen useful?

    Useful for clumping powders or liquids with particulates; helps reduce clogging and contamination risk.
  • When do I need vent lids/valves?

    Use vent lids/valves when contents may release gas/volatiles or face temperature swings; they help equalize pressure and reduce deformation/leakage.
