The top choice for lithium battery film handling and protection: PP hollow board packaging solutions.
In the precision manufacturing process of lithium batteries, the fragile battery membranes are highly susceptible to damage during transportation and handling due to abrasion, static electricity, or compression. Thanks to their unique lattice-like hollow structure, PP plastic corrugated sheets—also known as universal sheets or corrugated boards—are increasingly recognized within the industry as an effective protective packaging solution.
⚡ Core Advantage Analysis:
- Outstanding protective performance Hollow board boasts high rigidity and strong impact resistance. Its cushioning properties effectively minimize physical damage to battery films during handling and stacking, significantly reducing the rate of breakage. The smooth surface design prevents scratches on the film’s surface, ensuring product integrity.
- Electrostatic Discharge Safety Assurance By adding special masterbatches, hollow board boxes can be customized to be either antistatic (surface resistance of 10^6–10^9 Ω) or conductive (10^3–10^5 Ω), thereby eliminating the safety hazards caused by static electricity accumulation on lithium battery membranes.
- Lightweight Design and Circular Economy Its weight is only one-third that of traditional materials, significantly reducing logistics costs. This material is robust and corrosion-resistant, with a service life that is more than 4 to 10 times longer than that of corrugated cardboard boxes. It can be reused multiple times, aligning with the trend toward green packaging.
- Flexible customization to meet your needs. Thickness (2mm–7mm), color, and size can all be custom-tailored according to the specifications of the battery film. Paired with blade-card dividers and EVA lining, this design enables precise layered fixation, preventing shifting or collisions during transportation.
Summary PP hollow board packaging boasts four key features—damage prevention, anti-static properties, recyclability, and high degree of customization—providing end-to-end circulation assurance for lithium battery films.
