Every year, the same pattern repeats in the plastic packaging trade: from late November, buyers who order custom ziplock bags after mid-January find themselves competing for limited production slots. Chinese New Year is the single largest scheduling event on the manufacturing calendar, and for importers of self-sealing bags, resealable pouches, and flat poly bags, planning ahead is the difference between a smooth Q1 and a stockout.

Why Lead Times Stretch Before Chinese New Year

Most Chinese packaging factories wind down production one to two weeks before the holiday and restart gradually over the following two to three weeks. In the run-up, orders stack up quickly: film extrusion, printing, and bag-making lines all run at full capacity as customers push final shipments out before the shutdown. A standard lead time of 15 to 20 days for custom printed ziplock bags can easily extend to 25 or 30 days once the queue fills. Sea freight adds another variable, as vessel space out of South China becomes tight in the weeks before the holiday.

Key Dates to Put on Your Calendar

For 2027, Chinese New Year falls in early February. As a practical rule, custom bag orders confirmed by mid-December are comfortably inside the pre-holiday production window. Orders placed in January should be treated as post-holiday projects, with production restarting in late February or early March and delivery to port by mid-March. Buyers who need stock on shelves in Q1 should therefore aim to finalize artwork, film thickness, and packaging specifications in November or early December.

What to Prepare Before Placing a CNY-Season Order

Factories can move fast when the details are settled. Before requesting a quotation for custom ziplock bags, lock down the basics:

Specifications. Confirm bag size (folded width and total length), film thickness in microns, single-track or double-track zipper, and whether a hang hole or lip is needed. Changes after printing plates are made will cost both time and money.

Artwork. Supply print-ready files with correct Pantone references. Plate-making for gravure printing typically takes 5 to 7 days, so artwork approval is the first deadline that matters.

Volume and delivery split. If a full container is more than you need, ask whether part of the order can ship before the holiday and the balance afterwards. Many small and mid-sized factories, including ours, can split shipments to match your restocking rhythm.

Practical Tips from a Factory Floor

Buyers sometimes ask whether they should stock standard sizes instead of custom sizes to survive the holiday period. A hybrid approach often works best: keep a safety stock of your fastest-moving clear ziplock bags, and schedule custom printed bags so they arrive before mid-January. Also remember that raw material resin prices can move around the holiday, so early confirmation locks in both the schedule and the price.

How We Support Buyers Through the Holiday

As a small-to-mid sized manufacturer, we keep communication open through the holiday, confirm orders in the queue in the order they are received, and provide production photos before goods leave the warehouse. If you are planning custom self-sealing bags, colored ziplock bags, or flat poly bags for Q1 delivery, send your specifications early - a short email in November is worth a week of expediting in February.
