Heavy and oversized parcels risk box failure, bottom blow-out and lifting injuries. Focus on heavy-duty boxes, cross-sealing, edge protectors and clear handling marks.
Standard steps
- Heavy-duty boxEnough corrugate flutes; no damaged or damp cartons.
- Reinforce the baseCross / multiple tape strips on the bottom; staples if needed.
- Distribute weightCentre of mass low and central — never top-heavy.
- Edge protectorsRigid corners prevent punctures.
- SealCross method, tape overhanging the edges.
- Handling marksMark weight, this-way-up and two-person/mechanical lift.
Don’ts
- Thin, damp or damaged cartons for heavy goods;
- A single central strip on the bottom;
- Overweight goods in a normal box without reinforcement.
Above ~14kg, slide on rollers between surfaces rather than lift; above ~23kg consider lift assistance to cut injury and hidden cost.
