Bags, envelopes and paper do not run out together
A mailroom that reorders “packaging” when something runs out will always be late on one line and early on another. Grey mailing bags, padded envelopes and kraft paper are used by different goods. Soft clothing empties the mailing bags. A small fragile item empties the padded envelopes. Wrapping and interleaving empty the kraft. A mailer, an envelope, or paper is how to choose between them. This note is how to see the shortage before the bench improvises.
Give each line its own shelf and its own minimum. The minimum is not a feeling. It is a number of bags, a number of envelopes, or a remaining roll you can still see. When the shelf hits that number, the line goes on the next order, even if the other two shelves are full. A full shelf of kraft does not post a t-shirt. A full shelf of mailers does not stop a book creasing.
The person who packs is the person who sees the shortage. A buyer who only looks at invoices will reorder last month’s mix, including the size nobody used and excluding the size that ran out on a Thursday. Walk the shelf. What a packaging supplier stocks is the map of the ranges. The mailroom collects it.
What “low” looks like for each line
Mailing bags run out size by size. You can be out of the medium and still have a cupboard of the large. The large is not a substitute. Goods swim in it, and the filled bag can become a bigger parcel than you pay for. Count the size you actually use, not the total number of bags in the room. Grey mailing bags are the opaque polythene line, also called shoe bags, made in Europe from a blend of recycled film and described as 100% recyclable. Reorder that size, not a clear bag from a different job.
Padded envelopes run out by size as well. Jiffy Airkraft and Arofol, in gold and white, are the lined bags we stock as an authorised Jiffy distributor. If the bench has switched to mailers because the right envelope size is out, the goods that needed the cushion are being under-packed. That is the signal, even if nobody has said “we are low”. Board-back envelopes are a third shelf. Documents that must stay flat will be folded into a mailer the day that shelf is empty. Watch it separately.
Kraft is low when the roll is too small to finish the day’s wrapping, not when the core starts to show and someone “makes it last” by under-wrapping plates. The paper is 88 gsm, ribbed and machine glazed. A second roll on the dispenser, before the first expires, is the usual fix. Kraft tape is not this roll. If the thing that is low is the seal, order tape. If the thing that is low is the wrap, order the roll.
The top-up order
Put the low line on the order at the quantity that restores the minimum and covers the next stretch of work. Add a second line only if that shelf is also at its minimum. A top-up of one envelope size is a valid order. UK delivery is free over £50 ex VAT, and an order under that still leaves if it is placed by 3pm. Do not add a product you do not use in order to feel the order is “worth sending”.
Orders placed by 3pm are dispatched the same day. The aim is 5.30pm the next working day. A 1 to 3 day courier is also described, depending on the lines. If the last bag of the right size is on the bench this afternoon, you are already late. The reorder point has to sit far enough above zero that the later of those delivery descriptions still arrives before the shelf is empty. Friday’s order aims for Monday. A bank holiday moves it. A mailroom that discovers the shortage on Friday afternoon has a bare Monday.
TradePro, for trade businesses, starts at 5% and goes to 10% over £1,000 a month, with BACS as well as card and PayPal. It suits a mailroom that repeats the same sizes. It does not choose the size. The shelf does. If a size has not moved for a month, take it off the standing top-up. Dead stock of the wrong envelope is how the right one gets forgotten.
Improvising is the expensive signal
The moment someone folds a mailer to make a smaller one, or drops a rigid item into a padded envelope that is too slim, or wraps a soft good in half a sheet of kraft and calls it posted, the shelf is already wrong. Fix the line. Do not write a new procedure around the shortage. A carton used because the bags ran out may be the correct pack for that item, in which case the item should have been a carton all along, or it may be a waste of board. Mailing bags and padded envelopes are there to make that call when you are calm, not when the courier is at the door.
Stocked items can be returned within 14 days of purchase if a top-up was the wrong size. Call first. A size you simply ordered too many of, and have opened and crushed, is harder to call unused. Order the restoring quantity, not a year’s worth of a size you have only just identified.
Once a week, look at the three shelves before you look at the inbox. The mailroom that does this stops having emergencies that are really just a bag count. The goods have not changed. The minimum was late.
Keep the minimum written on the shelf, not in a document nobody opens. A piece of tape with a number is enough: how many of that size should still be there when you reorder. When the count and the number meet, the top-up is due. When they do not, you wait, even if it feels tidy to order everything on a Friday. Tidy Fridays are how the envelopes you do not use keep arriving.
