E-Commerce High Season mailing bag Stock Planning Guide

September-November and major campaign periods in e-commerce can multiply the daily shipping volume in a short time. Delay in the supply of mailing bags means that the packaging line stops, incorrect measurement is used and customer commitments are disrupted. This guide summarizes the high-season stock planning , gauge-micron standardization, and procurement schedule for B2B buyers in practical steps.

Seasonal campaigns, discount days and year-end gift period create more packaging lines and higher bag consumption for the same set of SKUs. Typical effects on the warehouse side:

50-200% increase in the number of packages per day (varies by category and channel)

You can check out our measurement guide for measurement and desi planning and our micron selection guide for durability.

Daily average consumption (ADU): Number of days of bag use ÷ in the last 8-12 weeks; round up the pre-campaign trend.

Lead time: Standard production + shipment; add sample approval time in custom printed bag. In typical B2B production, 2-3 weeks should be planned.

Safety stock: Lead time × ADU × safety coefficient (usually 1,2-1,5). Increase the coefficient during the campaign period.

Order point: (Lead time × ADU) + safety stock — new order is triggered at this level.

Limiting size diversity to reduce cost and waste is critical — we've covered standardization in our packaging cost optimization guide.

3-5 main bag sizes are sufficient for warehouse speed in high season:

Fix the micron according to the content weight; changing the thickness during the campaign period creates stock confusion

If there is a need for an invoice/waybill, plan the pocket model or invoice pocket stock in the same calendar — invoice pocket warehouse guide

In operations using branded bags, the high season order must take into account the sample approval + printing die time:

The campaign should not be started before the first production batch arrives at the warehouse; it can be considered as a spare unprinted stock buffer

Check out our printed bag guide for printing techniques.

With the ADU and campaign multiplier, the need for 8-12 weeks of bags was calculated.

3-5 standard size/micron lists distributed to operators

Panic purchases lead to unnecessarily thick film and oversize varieties; this increases both cost and plastic use. Planned stock, correct micron selection and use of recyclable PE should be considered together — our sustainable packaging guide .

How many weeks before the campaign should the order be placed? Add additional 2-4 weeks sample/production share in printed and special size as lead time + safety stock in unprinted standard bag.

How does the MOQ affect the stock plan? The minimum order quantity (kg) pushes the large batch at one time; if the ADU is low, the joint plan or half-year stock target with several customers/channels is evaluated to a common extent.

Can different supplier bags be used as a spare? It's possible, but differences in tape adhesion, micron feel, and size tolerance slow down the packing line. If possible, single source + security stock is preferred.

What to do with excess stock at the end of the season? The choice of standard size/micron makes it easier to consume the excess stock in the next quarter; the order should be broken down according to the campaign calendar in a very special printed bag.
