Client Requirements
Client Background and Application Scenario
In-vitro diagnostic (IVD) reagents have strict compliance and stability requirements for packaging.
An IVD reagent startup was developing multiple new reagent products.
Each one required small-batch custom packaging for clinical trials.
Products required full cold-chain transportation and storage at 2-8°C.
Client Requirements and Issues with the Previous Solution
The client had previously encountered several core issues.
First, cold-chain transportation compliance requirements were strict.
IVD reagents required full cold-chain transportation at 2-8°C.
The packaging had to meet cold-chain temperature requirements while also clearly marking the cold-chain conditions, expiration date, and temperature monitoring information on the outer carton.
Second, small-batch customization cost pressure was high.
At the new product R&D stage, the minimum print quantity for each reagent was very low, and traditional packaging solutions had high unit prices and high MOQ thresholds.
Third, regulatory marking density was high.
IVD packaging needed to carry a large amount of regulatory information, including:
reagent name,
specification,
batch number,
production date,
expiration date,
storage conditions,
manufacturing enterprise,
medical device registration certificate number, etc.
Layout design was crowded.
Core requirements: cold-chain packaging compliance, flexible small-batch customization, and standardized regulatory markings.
Project challenges:
✓ Cold-chain marking standardization
✓ Small-batch minimum print quantity
✓ High regulatory marking layout density
Solution
Solution Overview
We provided the client with a small-batch customization solution for IVD reagent cold-chain packaging.
The solution covered 4 new products.
F-flute corrugated color boxes were used for the outer cartons.
Paper card inner trays were die-cut and formed.
Labels used 70μ synthetic paper with freezer-grade adhesive.
Disposable temperature recording cards were equipped.
Selection Analysis
Why choose F-flute corrugated color boxes?
F-flute is approximately 2.0mm thick.
It is suitable for stacked storage and long-distance transportation.
Its load-bearing capacity is superior to ordinary three-layer corrugated board.
Why not choose laminated white cardstock?
Laminated white cardstock has inferior compression resistance compared to F-flute.
Long-distance cold-chain transportation involves significant vibration.
Why choose 70μ synthetic paper labels?
Synthetic paper maintains label appearance integrity in 2-8°C refrigerated environments.
Freezer-grade adhesive maintains stable tack in cold-chain environments.
Why not choose coated paper?
Coated paper tends to curl and lift in 2-8°C refrigerated environments.
Why choose paper card inner trays?
Paper card inner trays were die-cut from 350g white cardstock.
Slots were cut according to reagent bottle shapes, providing good cushioning and low cost.
Suitable for standard cylindrical reagent bottles.
Why choose disposable temperature recording cards?
Disposable temperature recording cards visually indicate whether temperature excursions occurred during transportation.
This facilitates joint verification between the shipper and the consignee.

Disposable temperature recording cards assisted transportation verification.
LeXiang Packaging Experience
Applicable scenarios: clinical trial stage packaging for new IVD reagents. Small-batch customization of cold-chain bioproducts.
Medical products requiring low-temperature-resistant labels.
Material recommendations: F-flute corrugated color boxes are the first choice for IVD reagent outer cartons. Synthetic paper with freezer-grade adhesive is the first choice for reagent bottle labels.
Cold-chain outer carton labels must use specialized low-temperature-resistant labels.
Non-applicable scenarios: IVD products stored at room temperature (no cold-chain configuration needed).
Mass-market launch products (traditional packaging solutions are more economical).
Notes: inner liner tooling requires an additional 3-5 days of production time. Ice pack configuration should be precisely calculated based on transportation duration.
Regulatory markings must be strictly laid out in accordance with GB/T 191 and YY/T 0466 standards.
Why Choose LeXiang Packaging
✓ Delivered 200 sets of cold-chain packaging for 4 IVD reagents (clinical trial stage)
✓ F-flute corrugated color boxes with standardized cold-chain markings per GB/T 191
✓ Temperature recording cards configured per carton, enabling full cold-chain temperature curve traceability
✓ Reagent bottle labels using the synthetic paper with freezer-grade adhesive combination maintained flat adhesion without lifting after 24 hours in a 2-8°C environment (verified by testing)

FAQ
体外诊断试剂的冷链包装为什么需要单独设计？
IVD试剂通常需在2-8℃环境下运输储存，温度偏移会导致试剂活性下降。冷链包装通常采用瓦楞彩盒外层加保温内衬加冰袋加温度记录卡的组合结构。
IVD冷链包装彩盒一般用什么材质？
推荐350g白卡纸覆哑膜或F瓦楞彩盒。F瓦楞约2.0mm，承压能力优于普通三层瓦楞，适合堆叠储存和长途运输。
冷链标签用什么面材？普通铜版纸可以吗？
不建议。冷链环境（2-8℃加凝露）下普通铜版纸容易吸潮起皱。建议用70μ合成纸加冷冻胶，或50μ PET面材。
IVD试剂包装需要做哪些合规标识？
外箱必须印有：冷链标识、朝上方向标识、防雨防潮标识、箱内试剂规格清单。内盒标签需要包含：批号、生产日期、有效期、注册证号等。
IVD试剂小批量（几十盒起印）能做吗？
可以。瓦楞彩盒数码印刷可低至50盒起印，传统胶印起印量500盒。冷链标签数码印刷可低至200张起印。
温度记录卡是必须的吗？
温度记录卡虽非所有国家强制，但99%的IVD品牌客户会要求配置。一次性温度记录卡成本约0.3-0.8元/张，可视化显示运输途中是否超温。
IVD冷链包装交期一般多长？
小批量定制（50-200盒）：打样3-5天，量产7-10天。中批量（500-2000盒）：打样5-7天，量产10-15天。
IVD包装厂家需要有什么资质？
纸盒标签本身不涉及医疗器械注册。建议供应商具备：印刷经营许可证、ISO 9001质量管理体系、食品级油墨合规声明、冷链标签耐低温测试报告。
改造为冷链包装的成本增加多少？
成本增加主要来自：瓦楞彩盒加保温结构、冷链合成纸标签替代铜版纸、温度记录卡。综合单盒总增加约2-4元。
IVD出口包装和内销包装有什么区别？
出口包装需额外考虑：CE标识和欧盟MDR法规要求、多语种标签、海运长周期的包装耐候性、目的国海关清关要求。
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。
包装材料怎么选？
常规材料按用途分级：彩盒首选350g白卡纸对裱或F瓦楞，标签首选70μ合成纸加丙烯酸系持久性胶。具体材料根据产品定位、起订量、批量交期综合评估。
