ORTPAK：PET Flame-Retardant Strapping – The Safety "Guardian" for New Energy Battery Packaging

Amid the rapid development of the new energy industry, the packaging safety of battery products has become a key concern in the supply chain. Specifically customized for battery scenarios, Qingxing Packaging's PET flame-retardant strapping has emerged as the "safety guardian" of industrial packaging with its unique performance.

This PET flame-retardant strapping developed by Qingxing Packaging is a packaging material tailored to the bundling needs of lithium batteries, power batteries, and battery modules. Available in multiple specifications, it can adapt to the packaging scenarios of battery products of different sizes and weights.

The PET flame-retardant strapping achieves a dual breakthrough in "strength + safety": On one hand, its tensile fracture stress is ≥450Mpa, and the joint strength is stably above 360Mpa. Its toughness and tear resistance are far superior to ordinary strapping, enabling it to firmly bundle heavy objects without easy loosening. On the other hand, it has passed the rigorous V0-level vertical flame retardancy certification (while meeting the HB-level horizontal combustion standard). Combined with an insulation performance of >6000M under DC 1000V, it fundamentally avoids the risks of open flames and electric leakage that may occur during the packaging of battery products. What's more noteworthy is its environmental adaptability: Even under complex working conditions such as high temperature and humidity, hot air oxidation, or contact with silicone oil, the retention rate of its joint tensile force can remain stable above 72%, ensuring packaging reliability during long-term transportation and storage.

Technical Parameters of Flame-Retardant Strapping

Performance and Advantages: Beyond Safety, More Reliable

• Maximum Safety Level: Passes both V0-level vertical flame retardancy and HB-level horizontal combustion certifications. Coupled with an insulation performance of >6000M under DC 1000V, it fundamentally avoids the risks of open flames and electric leakage in battery packaging, making it a "safety necessity" for new energy scenarios.

• Superior Strength and Durability: With a tensile fracture stress of ≥450Mpa and stable joint strength of ≥360Mpa, its toughness and tear resistance are 2-3 times that of ordinary PP strapping. It can bundle heavy objects without easy loosening or breaking.

• Strong Environmental Adaptability: Under complex working conditions such as high temperature and humidity, hot air oxidation, and contact with silicone oil, the retention rate of joint tensile force is still ≥72%, ensuring uncompromised packaging stability during long-term storage and transportation.

• Flexible Adaptability: Available in multiple specifications to cover different battery product sizes. It has no sharp edges, so it will not scratch the battery shell and is compatible with the high-speed operation rhythm of automated packaging equipment.

  
  

Full-Link Scenarios: The "Safety Link" from Production Line to Terminal

The application of this flame-retardant strapping runs through almost the entire circulation process of battery products, becoming the "standard packaging solution" for various scenarios:

• Power Battery Production Line Assembly: At the stacking station of prismatic lithium battery modules, it can cooperate with automated packaging machines to quickly bundle 5-10 stacked module shells. Its high toughness adapts to the high-speed pulling of equipment, and the absence of sharp edges prevents scratches on aluminum shells. Meanwhile, its flame retardancy reduces potential hazards caused by static sparks on the production line.

• Energy Storage Battery Warehousing and Sorting: Stacked containerized energy storage battery packs, when bundled with this strapping and stored in high-temperature warehouses, benefit from its V0-level flame retardancy to avoid the risk of chain combustion caused by battery self-heating. Its insulation performance also prevents electric leakage and short circuits between batteries.

• New Energy Vehicle Battery Transportation: Power battery packs during long-distance transportation often face jolting and sudden changes in temperature and humidity. With a joint tensile force retention rate of ≥72%, this strapping can prevent battery displacement due to packaging loosening. Additionally, its silicone oil resistance adapts to the insulation coating environment on the surface of battery packs.

• Waste Battery Recycling and Dismantling: Decommissioned power battery modules need to be temporarily bundled and fixed with this strapping before dismantling. Its corrosion resistance can adapt to the acid-base residue environment of recycling sites, and its flame retardancy reduces the risk of open flames caused by damaged battery cells during the dismantling process.

Currently, this PET flame-retardant strapping has become the mainstream choice for battery module packaging. Its targeted performance design not only solves the pain points of traditional strapping such as "insufficient flame retardancy" and "poor adaptability" but also helps new energy enterprises build a solid safety defense line in the supply chain. It is one of the key supporting materials for industrial standardized packaging.

Developed by Qingxing Packaging to meet the bundling and packaging needs of lithium batteries, power batteries, battery modules, and other products, the PET flame-retardant strapping features high tensile strength, excellent toughness, resistance to brittleness and cracking, and flame retardancy. It has reached the V0-level flame retardant grade for plastic products, can effectively adapt to the packaging scenarios of battery modules, and provides safe and reliable support for their bundling process.
