新能源电池包追溯二维码纸标签方案
Customer Requirements
Customer Background and Application Scenarios
A new-energy battery company sells its products to domestic vehicle manufacturers and overseas energy storage markets.
The customer required full-field traceability for battery packs and multi-scenario warehousing durability.
The QR code needed long-term readability to interface with after-sales traceability systems.
Customer Needs and Issues with the Original Solution
The customer had previously encountered several core problems.
First, battery pack traceability requirements were strict.
New-energy batteries involve safety incident traceability,
and downstream parties required each battery pack to be traceable to a specific production time, cell batch, and assembly worker.
The original labels could only carry model information and could not meet the full-field requirements of the traceability system.
Second, the storage environment was highly variable.
Battery packs needed to circulate through finished-goods warehouses, vehicle manufacturer assembly lines, 4S dealerships, and overseas energy storage warehouses.
Storage cycles varied in length, and temperature and humidity differences were significant.
Third, the QR codes lacked sufficient outdoor durability.
The original coated paper face-stock QR code labels faded after 6 months of outdoor sun exposure, affecting scan-based traceability.
Core requirements: full-field traceability for battery packs, multi-scenario warehousing durability, and long-term QR code readability.
Project challenges:
✓ Complete traceability data across 5 fields
✓ Multi-scenario storage temperature and humidity variations
✓ Long-term QR code readability
Solution
Solution Overview
We provided the customer with a battery pack traceability QR code label solution.
Covering 3 product lines and 8 SKUs.
The face stock used 100μ white synthetic paper with freezer-grade adhesive.
The QR code used GS1 Data Matrix, carrying 5 fields.
The lamination used 25μ matte film.
Material Selection Analysis
Why choose 100μ white synthetic paper?
Synthetic paper maintains label appearance integrity under warehouse humidity and outdoor sun exposure.
The QR code remains readable over the long term.
Why not choose 80g coated paper?
Coated paper fades under outdoor sun exposure, causing QR code failure.
Why not choose PET face stock?
PET would be an over-specification for this scenario.
Synthetic paper's outdoor durability is sufficient for warehousing and outdoor scenarios.
Why not choose 70μ synthetic paper?
70μ synthetic paper has weaker durability than 100μ under prolonged outdoor sun exposure.
Why choose freezer-grade adhesive?
Freezer-grade adhesive operates from -40°C to 90°C, covering all battery operating conditions.
It provides good initial tack and long-term adhesion on battery pack surfaces (metal, plastic, composite materials).
Why not choose rubber-based general-purpose adhesive?
Rubber-based adhesives have weaker long-term adhesion on metal surfaces than freezer-grade adhesive.
Why choose Data Matrix?
Data Matrix offers higher information density at small sizes.
It is more suitable for small-label scenarios on battery packs.
Why not print only a 1D barcode?
Downstream traceability systems require 5 fields, and 1D barcodes do not have sufficient information capacity.
Production Implementation and Quality Control

Case Summary
For multi-scenario warehousing and outdoor traceability requirements,
a 100μ synthetic paper plus freezer-grade adhesive plus Data Matrix QR code solution is generally more durable than coated paper.
This case involved the delivery of 12,000 traceability labels across 8 SKUs for a new-energy battery company.
The QR code remained readable over the long term under matte film lamination.
LeXiang Packaging Experience
Applicable scenarios: traceability marking for new-energy battery packs.
Product marking for multi-scenario warehousing (finished-goods warehouses, assembly lines, 4S dealerships, overseas warehouses).
Industrial products requiring long-term QR code readability.
Material recommendations: synthetic paper plus freezer-grade adhesive is the first choice for long-term outdoor traceability labels.
Data Matrix QR codes perform better in small-size scenarios. Digital printing is the preferred choice for flexible multi-SKU production.
Non-applicable scenarios: simple marking with short storage cycles (less than 30 days). Product marking in indoor room-temperature environments.
Notes: synthetic paper face stock has a higher unit price than coated paper, but the long-term traceability value outweighs initial cost savings.
We recommend reserving expansion space for future variable data fields. QR code dimensions should be designed according to the minimum readable size.

FAQ
新能源电池标签可以用铜版纸吗？
短期可以（1-3个月），但电池仓储和运输环境复杂（湿气加油污加低温），铜版纸6个月内字迹会模糊。建议用合成纸。
冷冻胶和普通持久性胶的区别？
普通持久性胶工作温度-10℃到60℃，低温下胶层变脆。冷冻胶工作温度-40℃到90℃，覆盖电池全工况。胶水初始粘性也不同——冷冻胶30分钟达到最终粘性80%。
二维码追溯标签用QR还是DataMatrix？
QR适合手机扫码，DataMatrix适合工业扫码枪（更紧凑、容错率高）。本案例用GS1 DataMatrix，是医疗器械和工业领域的事实标准。
为什么用哑膜不用亮膜？
二维码扫码对表面反光敏感。亮膜在入射角变化时反光强度变化大，扫码成功率受影响。哑膜表面漫反射均匀，扫码成功率高（实测从88%提升到99%以上）。
电池包标签要抗UV吗？
如果是长期户外暴晒（如户外储能电站），需要抗UV合成纸。本案例电池仓储为主，UV影响小。
格拉辛底纸vs牛皮底纸怎么选？
自动产线选格拉辛底纸——表面光滑、透光率高、传感器识别率99.9%。手工贴标可以用牛皮底纸——成本低、抗撕裂。
二维码追溯系统怎么对接？
需要明确二维码格式（GS1标准/自定义）、数据来源（客户ERP/乐享系统）、扫码端（手机/扫码枪）。本案例乐享负责标签生产，二维码数据由客户提供。
电池包标签可以贴电芯上吗？
不建议。电芯工作温度100℃以上，普通合成纸会软化。需要用PI（聚酰亚胺）材料加特殊胶水，工艺完全不同。
追溯标签的二维码内容怎么定？
本案例格式：DI（厂商加产品代码）加PI（批次加生产日期加序列号）。具体字段根据客户追溯系统需求调整。
新能源电池追溯标签的成本？
单张成本约0.3-0.6元（包含合成纸加冷冻胶加哑膜加数码印刷加二维码）。月用量10万张以上，单张可降到0.2元。
定制起订量一般是多少？
数码印刷方案通常50套起订即可打样。具体看盒型与工艺复杂度。打样确认后启动批量生产。批量生产500套起订可降低单价。交期按文件确认后5-7个工作日。
打样需要多长时间？
数码印刷打样通常1-3个工作日出样。打样确认后再启动批量生产。具体交期看工艺组合与材料选择。打样费在批量合同中可抵扣货款。
批量交期一般是多久？
打样阶段3-5个工作日。批量生产5-7个工作日。具体交期取决于SKU数量与工艺复杂度。急件可加急处理，费用另计。材料按订单分批采购。
