Traceability QR Code Paper Label Solution for New Energy Battery Packs

It is feasible in the short term (1-3 months), but battery storage and transportation environments are complex (humidity plus oil stains plus low temperature), and the print on coated paper will blur within 6 months. Synthetic paper is recommended.

Standard permanent adhesive operates from -10℃ to 60℃, and the adhesive layer becomes brittle at low temperatures. Freezer adhesive operates from -40℃ to 90℃, covering the full operating range of the battery. The initial tack is also different—freezer adhesive reaches 80% of its final adhesion within 30 minutes.

QR is suitable for mobile phone scanning, while DataMatrix is suitable for industrial scanners (more compact, with higher error tolerance). This case uses GS1 DataMatrix, which is the de facto standard in the medical device and industrial sectors.

QR code scanning is sensitive to surface reflection. With glossy film, the reflection intensity varies significantly with changes in incident angle, affecting scan success rate. Matte film provides uniform diffuse reflection on the surface, with a higher scan success rate (actually measured improvement from 88% to over 99%).

If long-term outdoor sun exposure is involved (such as outdoor energy storage stations), UV-resistant synthetic paper is required. In this case, battery storage is the primary scenario, so UV impact is minimal.

Choose glassine liner for automated production lines—smooth surface, high transmittance, and 99.9% sensor recognition rate. Kraft liner can be used for manual labeling—lower cost and tear resistant.

It is necessary to clarify the QR code format (GS1 standard/custom), data source (customer ERP/LeXiang system), and scanning end (mobile phone/scanner). In this case, LeXiang is responsible for label production, and the QR code data is provided by the customer.

Not recommended. Cell operating temperatures exceed 100℃, and standard synthetic paper will soften. PI (polyimide) material with special adhesive is required, and the process is entirely different.

Format in this case: DI (manufacturer plus product code) plus PI (batch plus production date plus serial number). Specific fields are adjusted based on the customer traceability system requirements.

The unit cost is approximately 0.3-0.6 RMB per label (including synthetic paper plus freezer adhesive plus matte film plus digital printing plus QR code). With monthly usage of over 100,000 labels, the unit cost can be reduced to 0.2 RMB.

Digital printing solutions typically require a minimum of 50 sets for proofing. The specific quantity depends on the box type and process complexity. Mass production is initiated after proofing confirmation. A minimum order of 500 sets for mass production can reduce the unit price. The lead time is 5-7 working days after file confirmation.

Digital printing proofing typically delivers samples within 1-3 working days. Mass production is initiated after proofing confirmation. The specific lead time depends on the process combination and material selection. The proofing fee can be deducted from the payment in the bulk contract.

The proofing phase takes 3-5 working days. Mass production takes 5-7 working days. The specific lead time depends on the number of SKUs and process complexity. Urgent orders can be expedited with additional fees. Materials are purchased in batches according to the order.
