No Compromise on Quality

For the past 21 years, we’ve pushed for the highest quality management in our production processes, following the ISO9001 quality system. Our passion for quality led us to attain certifications from reputable bodies like SA8000, BSCI, SEDEX, and Disney FAMA.

Additionally, our bags are covered with a permanent warranty, covering any quality concerns and providing you with reliable solutions.

The 3 pillars of Our Quality Assurance

From raw material screening to finished product quality inspection, Polyking has established a robust quality control system. We mainly focus on the following three major aspects to ensure our bags are of high quality.

Quality Raw Materials Matter

Materials go through strict quality audits before entering our warehouse, with fabrics passing our fabric inspection machines. Polyking can source the right materials from credible suppliers that match the EU’s REACH or California’s PROP65 standards. We also provide test reports per request.

Quality Check

Using the fabric inspection machine to make the cloth translucent, our experienced quality inspectors will then identify the quality of the cloth.

Specification Measurement

We use vernier calipers and grammometers to measure the specifications of the fabrics to ensure they meet production requirements.

Color Fastness Test

Our specialized inspectors wipe the fabric 50 times with high temperature water or alcohol to check the color fastness.
During the Whole Production Process

Attention to Details

Bags and cases will be inspected by our QC staff throughout the production process. From appearance to craftsmanship to specifications, we pay attention to every detail. By doing so, we guarantee that every bag that reaches you have superior quality.

Meticulous Final Test

Before our custom bags leave the warehouse, they pass through a needle inspection machine to prevent any broken needles from staying on the bags and reaching your customers. A dedicated quality control auditor is assigned to each project, checking that the batches pass our appearance, workmanship, and performance standards.
