⚠️ Mistakes to Avoid
Mistakes to Avoid
The packaging and printing mistakes that quietly cost sellers the most money — most of them show up long before anything actually breaks.
Packaging Mistakes
The ones that quietly inflate your shipping costs or your damage rate.
📐
Using One Box Size for EverythingAn oversized box means more void fill, more dimensional weight charges, and more room for contents to shift in transit.
🫧
Skipping Void Fill to Save MoneyA near-empty box costs less upfront but leads to far more damage claims and returns down the line.
🎗️
Sealing With Only the Center Seam TapedBoxes need an H-taping pattern across all seams — a single strip down the middle is the most common reason boxes pop open in transit.
💪
Ignoring the Box's Strength RatingA box's ECT or burst rating needs to match the weight it's carrying, not just look sturdy enough by eye.
📦
Reusing Boxes With Structural DamageA box that's already been crushed or soaked has lost most of its rated strength, even if it looks fine after drying out.
💧
Storing Packaging Supplies in a Damp SpaceHumidity quietly weakens corrugated board strength well before a box shows any visible signs of damage.
Printer & Label Mistakes
The ones that lead to smudged, rejected, or wasted labels.
🖨️
Buying Direct Thermal Labels for Long-Term UseDirect thermal print fades with heat and sunlight — fine for short-term shipping labels, a poor choice for anything meant to last.
📏
Skipping Calibration After Switching Label SizesPrinters need to relearn label size and gap position every time you switch roll sizes, or prints drift out of alignment.
🌡️
Cranking Print Darkness Up to Fix a Faint PrintA faint print is often a dirty print head, not a darkness setting problem — over-darkening burns through labels faster and can damage the head.
🧻
Never Cleaning the Print HeadLabel liner residue builds up on the print head over time, causing streaky prints that look like a hardware failure.
📦
Buying Off-Brand Labels Without Checking DiameterA roll core that doesn't match your printer's spindle, or a roll diameter too large for the housing, jams more often than it saves you money.
🔌
Not Checking Software Compatibility Before BuyingA printer that doesn't integrate with ShipStation, Shopify, or Pirate Ship means manually reformatting every label, every time.
