The run-up to Black Friday and Christmas is the point in the year where packaging stops being a background task and becomes something that can genuinely make or break how smoothly your busiest weeks go. Running out of mailing bags mid-November, or discovering your tape supplier's lead time has stretched to a week right when you need it fastest, is entirely avoidable with a bit of planning done in advance rather than during the rush itself.
This guide covers how to plan packaging supplies for the seasonal peak, when to start, and what tends to catch sellers out.
Why seasonal planning matters more than it seems
Packaging suppliers, couriers and the businesses ordering from them all experience the same surge at the same time. Stock that's reliably available in September can be tighter in November, simply because demand across the entire supply chain spikes together. Lead times that are normally same or next day can stretch during the busiest weeks, both for suppliers and for the couriers delivering your own stock to you.
This means the cost of leaving packaging planning until you're already in the rush isn't just inconvenience, it's the real risk of being unable to dispatch orders on time because you've physically run out of something you need. For a seasonal sales spike, that's a direct hit to revenue and customer experience at exactly the point you most need things to go smoothly.
When to start planning
A reasonable rule of thumb is to start thinking about seasonal packaging needs around two to three months before your busiest period. For most UK sellers, that means starting to plan for Black Friday around September, and using the post-Black Friday period to assess and top up before the Christmas rush itself, which typically runs through to around the third week of December for standard delivery.
This timeline gives you room to estimate volume based on previous years if you have the data, place a meaningful bulk order while suppliers still have normal stock levels and lead times, and still have time to place a top-up order if your initial estimate turns out to be too conservative.
Estimating how much you'll actually need
If you've traded through a previous Black Friday or Christmas period, your own sales data is the best starting point. Look at your order volume during the equivalent period last year, and apply a reasonable growth estimate based on how your business has grown since then. If you're a new business without historical data, a useful approach is to estimate your highest normal weekly volume, then plan for two to four times that volume during peak weeks, since seasonal spikes for small online sellers commonly fall in that range, though this varies considerably by product category and customer base.
Whatever number you arrive at, it's worth rounding up rather than down. Running out of packaging mid-surge is a far more costly problem than having a bit of surplus stock left over in January, particularly since most packaging, stored properly, keeps perfectly well for use in the following months.
What to stock up on
The specifics depend on what you sell, but a few categories are worth reviewing for any seller ahead of a seasonal peak.
Mailing bags in your core sizes
Identify the one or two sizes that cover the bulk of what you typically send and order a bulk quantity well ahead of the rush. This is also a good time to review whether you've been using the right size consistently, since any inefficiency in sizing compounds significantly across a high-volume period. If your typical busy-period order includes gift purchases, consider whether a coloured mailing bag for gift orders specifically is worth adding to your usual grey stock, since presentation tends to matter more to buyers during gifting season.
Packaging tape, in greater quantity than you'd expect
Tape consumption scales directly with parcel volume, and it's an easy thing to underestimate because a roll feels like it should last longer than it does once you're sealing several times the normal number of boxes each day. Calculate your expected tape usage based on the box-per-roll estimates for your typical box size, then order with a meaningful buffer on top, since running out of tape mid-pack during a busy period is a more disruptive problem than it sounds.
Grip seal bags, if small items make up part of your seasonal range
If you sell gifts, jewellery, accessories or any small item category, the seasonal increase in this kind of order often outpaces general order growth, since small items make popular, low-commitment gift purchases. Reviewing your grip seal bag stock alongside your mailing bags is worth doing rather than assuming the same ratio of small-item to clothing orders will hold through the gifting period.
Don't forget labels
Thermal label stock is easy to overlook because a roll of 500 sounds like a lot until you're printing several hundred labels a week during peak season rather than your normal volume. Check your label stock against your projected volume the same way you would tape, and make sure you have enough on hand that a delay in reordering doesn't interrupt dispatch.
Placing your order with enough buffer in the supply chain
Even with a supplier offering same-day or next-day dispatch under normal conditions, it's worth placing seasonal stock orders with a bit more lead time than you'd normally need, simply because courier networks themselves are under more pressure during this period and even a reliable supplier's outbound delivery to you can be marginally slower during the busiest weeks. Ordering two to three weeks before you expect to need the stock, rather than the few days you might normally allow, removes this risk entirely.
What to do if you underestimate
Even with good planning, demand can outpace expectations. Having a plan for this scenario before it happens is worth more than hoping it won't, since decisions made calmly in September are better than ones made in a panic in late November.
Know in advance what your supplier's fastest available turnaround is for an emergency top-up order, and keep their contact details easily accessible rather than having to search for them mid-crisis. If you're a registered business, ask your supplier in advance whether trade or priority ordering is available during peak periods, since some suppliers do offer this for established account holders even when general stock is under pressure.
Reviewing what worked after the season
Once the rush is over, it's worth a short review while it's still fresh: did you run out of anything, and if so, by how much. Did you overbuy anything significantly, and if so, is that stock still usable for general use through the rest of the year. Was your size and quantity mix right for what customers actually bought, or did the seasonal product mix shift in a way that changed what packaging you actually needed most.
This review is what makes next year's planning faster and more accurate than this year's. A business that does this consistently tends to get progressively better at seasonal planning each year, rather than re-learning the same lessons from scratch each November.
A simple seasonal planning timeline
Around 10 to 12 weeks before your peak period, review last year's data or estimate volume if you don't have it, and place your main bulk order for mailing bags, grip seal bags, tape and labels. Around 4 to 6 weeks before, do a stock check against your actual run rate so far and place a top-up order if needed while normal lead times still apply. In the final two weeks before, make sure everything is physically on hand and accessible, rather than still in transit, and confirm your supplier's emergency turnaround details in case you need them. After the peak period, do a short review to inform next year's planning.
