Garment Poly Bags Category Planning Guide for Trading Companies: the 2026 season Guide No.89

South Korea is a competitive market for garment poly bags, and the suppliers who win repeat orders are the ones that control their process rather than their price list. The notes below are aimed at Trading Companies sourcing for the 2026 season, and they focus on the details that decide quality and margin.

Inspection Points Buyers Should Book

Agree in writing what happens if the inspection fails, including who pays for rework and re-inspection. Measure a full sample set against the specification sheet, and record every deviation, however small. Keep an approved golden sample sealed at the factory and a matching one in your office. Book an in-line inspection at 30 percent completion: that is the cheapest moment to fix a problem. Photograph the inspection, the packing and the pallet; images settle most disputes faster than documents.

Supplier Selection and Vetting

Visit or video-audit the line; a five-minute walk-through reveals more than a page of certificates. Request the production schedule before you pay the deposit, so you can see where your order sits. A factory that can show recent garment poly bags export documents and test reports is a safer partner than one that only shows samples. Confirm who owns the moulds, the artwork and the tooling, especially if you intend to reorder the same design next season.

Lead Time and Order Planning

Build a buffer of seven to ten days between the ex-factory date and the sailing date for the unexpected. Standard production for garment poly bags runs 30 to 60 days after sample approval, so build the calendar from the approval date. Keep a second qualified factory on file, because a single-source season carries avoidable risk. Book capacity in advance for peak months; a factory that is full in August cannot rescue a late October order. Review the schedule weekly against actual output, not against the original promise.

Compliance, Testing and Documentation

Chemical and packaging rules differ by market, so confirm the destination requirements before you finalise the packing spec. For South Korea, check the labelling rules on material content, care instructions and country of origin before printing. Confirm that the test house is accredited and that the report names your product, not a generic specimen.

Materials and Construction

The quality buyers pay for is clarity and seal strength, and it comes from the LDPE or recycled PE with an adhesive strip combined with careful finishing. Ask to see how the product looks after it has been used for a week, not only on the day it leaves the factory. Consistency across a batch is a common weak point in garment poly bags, so approve a range sample rather than a single piece. The LDPE or recycled PE with an adhesive strip determines most of the look, feel and durability, and it is the first item to write into the specification. Specify composition, weight and tolerance in numbers, not adjectives.

Where the Price Actually Comes From

The price of garment poly bags breaks down into material, labour, finishing, packing and margin, and only some of those move with volume. Freight, duty and inland handling can add more than the factory price difference, so compare landed cost, not FOB. A small upgrade in material or packaging changes the cost meaningfully, so price two specifications side by side.

Five Boxes to Tick Before You Order

The five controls are simple: specification, sample, inspection, packing and documents. Get them right and you remove most of the risk from a garment poly bags order.
