Why Cartons Fail in Transit — It’s Not Just the Box
When a carton fails in transit, the first things usually questioned are the cartons themselves or the way it was packed.
Was the carton strong enough?
Was it overfilled?
Was there enough void fill?
Was the product packed correctly?
These are important questions — but they are only part of the picture.
In reality, carton performance depends on three things working together:
Carton quality, packing method, and sealing approach.
The first two are often given the most attention. Businesses spend time choosing carton grades, reducing empty space, protecting products, and improving packing methods. But the final step — how the carton is sealed — is often overlooked.
And that can be the difference between a carton arriving securely or arriving open, damaged, or poorly presented.
A strong carton can still fail if the seal does not hold.
A well-packed carton can still open if the tape lifts under pressure.
A recycled, dusty, or uneven carton can still cause problems if the tape cannot bond properly.
Standard plastic tape sits on the surface of the carton, so its performance can be affected by dust, recycled board, uneven flaps, internal pressure, or carton movement during freight.
Water-activated tape works differently. Once activated with water, it bonds into the fibres of the carton, creating a strong, secure, and tamper-evident seal. This helps the sealing method become part of the carton’s strength, rather than just a strip of tape over the top.
The right dispenser also improves consistency by applying the correct tape length and moisture level each time, helping every carton leave the packing bench sealed the same way.
At Packline Solutions, we help businesses look at carton sealing as part of the full packaging system — not just the final step before dispatch.
Because carton quality, packing method, and sealing approach all need to work together. If the tape is overlooked, even a good carton and a good packing process can still fall short.
