Certification and guidelines

Lithium batteries fall into hazard class 9, which means that the goods pose a not insignificant risk to the environment during transport. When transporting lithium batteries, numerous requirements and guidelines must be observed.

Certified for Packaging Group II

The containers of the FLEX-BOX series meet the requirements of Packaging Group II, meaning substances with medium hazard potential may be transported in them. To achieve this classification, crash tests from 1.2 m must be passed.

Different properties and fill materials

Height of the folded box

The Variant "Basic" offers a folded height of 282 mm, enabling compact and space-saving storage. The "Advanced" and "Premium" variants offer a folded height of 330 mm.

E-glass fiber batt mats and PyroBubbles provide extra protection

The Advanced variant protects the contents with E-glass fiber batt mats against shocks and vibrations. This fill material is non-combustible and not electrically conductive. For the highest safety requirements, the "Premium" variant is available.

Fill material and safety features

In the "Basic" variant, no additional fill material is required. This option is ideal for transporting undamaged and non-defective batteries, according to packaging regulation P 903 which does not require special fillers. For increased safety we recommend the "Advanced" variant, which is equipped with E-glass fiber batt mats. With the Advanced variant, damaged and defective batteries, prototypes and batteries for disposal or recycling can also be stored or transported. For maximum safety and protection we recommend the "Premium" variant. Here, E-glass fiber batt mats are used in combination with 20 included PyroBubbles cushions. The box is filled with the fire-extinguishing material PyroBubbles®, which forms a closed and thermally insulating layer around the fire source. The PyroBubbles provide an additional fire protection function and contribute to safety, especially when storing or transporting lithium batteries or lithium-ion cells.

ADR special provisions

The "Basic" variant contains no specific ADR special provisions. The "Advanced" and "Premium" variants, however, comply with ADR special provisions SV 376, SV 310. Transport under SV636 is of course also possible. These regulations are intended to optimize handling and transport of lithium batteries and to ensure safety throughout the transport chain, especially with regard to recycling and disposal.

THE FLEX-BOX series enables you to select the appropriate variant according to your individual requirements and always ensures the highest safety standards. Rely on our products to transport your lithium batteries safely and efficiently.

Future-oriented

Lithium-ion batteries will be indispensable in all industrial applications in the coming years. However, when misused, batteries can pose a significant risk during manufacture, storage, and transport. By purchasing these boxes, you secure yourself against larger financial damages from the start. International customers, including those in automotive and power supply sectors, rely on this proven technology.
