Frequently Asked Questions
Will waterproof labels completely stop smudging in humid conditions?
Waterproof film labels greatly reduce smudging because the ink or toner sits on a coated surface rather than soaking into paper. Laser-printed toner on waterproof film is the most reliable combination. However, complete protection also depends on proper drying/cooling after printing, correct printer settings, and good adhesive contact to the package. For maximum security use a waterproof label plus a clear sleeve on rough or wet shipments.
Can I use these labels with an inkjet printer?
Most film-based waterproof labels in this guide are designed for laser printers because toner bonds differently than liquid ink. Using inkjet without a waterproof topcoat often leads to smearing. If you must use inkjet, look for labels explicitly labeled inkjet-compatible and consider a clear sleeve or permanent topcoat to seal the ink.
How should I apply labels to damp or corrugated boxes to prevent peeling?
Always try to apply labels to a dry, clean area. For corrugated or wet boxes, use a clear adhesive sleeve that creates a large, uniform bond area. If a sleeve isn’t practical, press firmly along the entire label surface, avoid packing near seams, and consider pre-taping a smooth piece of cardboard to the box as a base for adhesion. Using Ultrahold or strong permanent adhesives will also reduce peeling risk in humid transit.
