Bag Inspection Checklist: 40 Points to Verify Before Shipment

A checklist without limits is a memory aid, not a control. Write "print alignment" as a line item and two inspectors will reach different verdicts on the same unit. Write it as "displaced no more than 2 mm from the seam reference, measured with a steel rule" and they will agree. The difference between a checklist that gets used and one that gets filed is whether every line can be judged without an opinion.

The second reason a forty-point list earns its keep is what happens between visits. Findings recorded by line number can be counted, and counts compared across lots show whether a category is improving. That turns every inspection into data rather than a verdict, and data is what lets a repeated fault be corrected rather than sorted out lot after lot.

It also changes behaviour on the line. A specific list issued in advance tells production exactly which features somebody independent will examine, and features that are examined get made properly. The effect is strongest on the second and third lots, once everybody involved has seen a report.

Why Forty Points and Not Ten?

Because faults that reach customers are rarely dramatic. They are the slow accumulation of small things: a closure that stiffens, a label that creeps, a panel at the edge of tolerance. Ten broad checks find disasters and miss drift. Forty specific ones cost perhaps fifteen minutes more per visit and catch the things whose removal actually changes how the shipment performs.

There is also a commercial argument. A checklist written to forty points becomes the evidence base for any later conversation about quality trends: counts per category over several lots show direction, and direction is what allows a defect to be fixed rather than sorted.

What Should Be Checked on the Shell and Panels?

Start here because everything afterwards depends on it, and because appearance adjudication gets harder once units have been handled. Compare every panel against the approved counter-sample rather than against other units in the lot: comparing units to each other merely establishes that they are consistently wrong.

Lighting deserves a line of its own in the instruction. Colour, sheen and print quality are all judged under whatever light happens to be available, and a shaded corner on a production floor is enough to hide a shade step. Ask for daylight or a stated light source, and record what was used.

What Should Be Checked on Sewing and Construction?

Ten points covering the three things that decide whether a bag survives its duty: whether the seams were specified correctly, whether they were sewn to that specification, and whether the load concentrations were reinforced. The first and third are design questions answered long before this visit; the middle one is what the inspector can actually verify.

Take the reverse side seriously. Operators working at awkward angles compensate inside the construction, and the compensation is invisible from outside until the seam opens. Turning units inside out is slow, so agree how many units get that treatment per lot rather than leaving it to whichever units are easiest to reach.

What Should Be Checked on Hardware and Closures?

Function before finish, and in every case cycle the component rather than looking at it. A buckle that releases correctly twenty times is a better indication than one that looks well plated. Where closure cycling is part of the product specification, agree the number of cycles and record what happened.

Finish deserves the second pass: plating consistency, burrs, sharp edges, and the small flashes of material that appear where hardware is moulded. Burrs belong in the critical class rather than the cosmetic one, because they are the sort of finding that turns into an injury report.

What Should Be Checked on Dimensions, Packing and Marking?

Measure on relaxed units laid flat, using the reference points named in the tech pack. Dimensions taken to a finished edge rather than a seam, or on a unit stuffed for photography, produce numbers that are accurate and irrelevant. State the method once and every later dispute becomes arithmetic.

Packing and marking complete the set because they are what the destination actually experiences. Miscounts, mismatched shipment marks and mixed cartons cause more receipt disputes than any appearance finding, and they are the quickest and simplest checks on the whole list.

Two related questions always follow, and both are worth answering before they are asked. Whether the same checklist suits every colourway — yes, with the colour-specific reference points recorded per colourway rather than once for the style. And whether a checklist can be too long — yes, once it starts generating findings nobody acts on; cut any line whose last three verdicts was never used.

How Is Each Point Judged Pass or Fail?

Through the defect classification, which assigns every checklist line a class meaning by location. The checklist says what to look at; the classification says what it is called when it is wrong. Programs that run one without the other end up with inspectors inventing classes on the day, which is exactly the failure mode the paperwork was meant to prevent.

The practical structure is one shared document: forty numbered lines, each with the check, the method, the limit, and three class columns for the locations where the fault can appear. One page per ten lines, four pages, and everybody in the room can find anything in under a minute.

Who Owns the Checklist?

The buyer writes it, the tech pack supports it, and the vendor uses it. That combination is not about authority but about usefulness: a list written by the party whose margin depends on shipping today tends to omit the checks most likely to fail, and a list written by somebody who has never seen production omits the checks that actually get done.

The best versions come from one amendment cycle. Write forty lines, run them once during a first-article check, and delete or rewrite whatever produced a false finding. A list that survives its first real use unamended usually means nobody used it properly.

How Do You Turn the Checklist Into a Defect Classification?

Add two columns and the conversion is done: the class for each location the fault can occur in, and the counting convention. Then read the checklist into the sample plan — every non-conformity counted into its class, every class read against its own column.

Finally, keep the checklist versioned and dated. A lot inspected against revision two while everybody argues about revision three has no reliable record, and version numbers take ten seconds to print on every copy.

Two working documents finish the set. Everything coming out of the checklist has to be read against a plan, and the sampling table tells you how much evidence that plan actually buys. Where a finding is contested afterwards, the dispute route should have been agreed long before anybody needed it.

One practical arrangement makes all forty points workable: pair them with the order they are worked in. Appearance first while units are clean, then construction, then hardware, then measurement, because later stages handle units and handling changes appearance. Working out of sequence produces findings that are artefacts of the inspection itself.

Everything else is detail: the checklist fits on four pages, all forty lines are numbered, and each has a reference somewhere in the tech pack or on the counter-sample. Build it once and the second product takes an hour rather than a day.
