How to diagnose a packaging problem
Most packaging failures are predictable. The trick is to isolate when it fails — before production (a spec or material mismatch), during production (a process setting), or after (handling, humidity, and time). A defect that shows up on every unit points at the spec or the setup; one that's random points at process drift or handling. Once you know the family, the specific cause usually falls out of a few tell-tale signs.
Is it your fault or your supplier's?
- Spec problems are usually yours to fix — the wrong material, adhesive, board grade, or tolerance was chosen up front. The good news: they're the cheapest to prevent, at quote time.
- Process problems are usually the supplier's — seal temperature, score depth, glue coverage, color target. These get fixed on the line.
- Handling and environment sit with whoever controls the warehouse and the truck — humidity, stacking, and time affect nearly everything.
The cheapest defect is the one caught before production. PackOS surfaces the spec decisions that cause most of these — material, dieline, and tolerances — at quote time, and the full packaging problems library covers each symptom in depth.
Questions
How do I diagnose a packaging defect?
Isolate when it happens: on every unit or at random, and before, during, or after production. A defect on every unit usually points to the spec or setup; a random one points to process drift or handling. Then match the tell-tale signs to a specific cause and apply the fix, which the full guide for each symptom covers.
Is a packaging problem my fault or my supplier's?
Spec choices made up front, like the wrong material, adhesive, or board grade, are usually yours to fix and are cheapest to prevent at quote time. Process settings like seal temperature, score depth, glue coverage, and color target are usually the supplier's and get fixed on the line. Handling and humidity sit with whoever controls the warehouse and transport.
Why do my labels keep peeling off?
Peeling and bubbling usually trace to an adhesive that does not match the surface, a contaminated or low-energy plastic surface, cold or wet application, or not enough dwell and pressure. Match the adhesive to the substrate, clean and dry the surface, apply at the right temperature, and give it time to reach ultimate adhesion.
Why is my box crushing in shipping?
Crushed boxes usually mean the board was under-specified for the real-world load after humidity and stacking derate its strength, or there is too much headspace, overhang, or poor alignment on the pallet. Spec the board to the derated load, right-size to cut headspace, column-stack and align, and protect from humidity.
