Put thickness on a clear measurement basis
Write film thickness in micrometers and ask whether it is nominal or measured. Record the agreed tolerance and test method rather than assuming every quotation uses the same basis. Width, usable roll length and net film weight belong alongside thickness. A label such as 'heavy duty' is not a substitute for these fields, and an advertised thickness is not an approved pallet-load rating.
Make a load profile from observations
Record pallet length, width, overall height and gross mass, with photographs from several sides. Note protrusions, sharp corners, irregular stacking, fragile products and any settling after packing. Identify the contact between the goods and pallet. Divide substantially different loads into separate trial groups instead of assuming one successful sample covers every shipment in the warehouse.
Keep equipment and wrapping settings visible
For a machine, record model, carriage type, pre-stretch setting, wrap program and any added top or bottom revolutions. For manual wrapping, describe the agreed overlap and reinforcement pattern. Equipment-maker guidance recommends retaining the settings that produced the required containment. A change in film thickness or pre-stretch should trigger a check of the wrapping result, not just a recalculation of roll cost.
Do not confuse more film with a validated solution
A trial should record film breaks, corner damage, loose tails, load-to-pallet attachment and observed movement. Where containment is measured, use the agreed equipment and locations consistently. Do not invent a force target from pallet weight or transfer a number from an unrelated load. Ask the responsible packaging or transport specialist to define acceptance for demanding shipments and any required transport testing.
Compare candidates without changing every variable
Label the current film and candidate, retain the same load family and record all settings for each run. Measure film used per pallet and note adjustments needed to meet the agreed checks. If the film only works with a different program, keep that program with the approval. Record sample count and exceptions so a purchasing decision does not rest on one unusually easy pallet.
Use the RFQ to define what remains unknown
Send the current roll label, width, thickness, net weight or usable length, core dimensions, load profile and wrapper details. Include the reason for the change: fewer breaks, less material, different appearance or a new machine. SAFLO can review the brief before a final quote; the worksheet is a buyer confirmation tool, not evidence of tested performance or a promise that one thickness fits every load.
