In recent years, with the rapid development of industries such as new energy vehicles, high-end logistics, and precision electronics, the demand for foamed polypropylene (EPP) materials with characteristics such as lightweight, high buffering, temperature and corrosion resistance, recyclability, and environmental friendliness has continued to rise. Especially in scenarios such as new energy vehicle battery cell packaging, logistics turnover trays, and fragile goods cushioning packaging, EPP has become the mainstream material selection. There are currently a large number of supply side enterprises in the EPP industry, with significant differences in technology, production capacity, and service capabilities. When selecting suppliers, buyers often prioritize the top enterprises with high exposure, while some high-quality manufacturers with deep expertise in niche fields and solid technology but low exposure are ignored by buyers due to a lack of publicity. To assist purchasers in various industries in efficiently selecting suitable EPP suppliers, this guide selects representative enterprises with outstanding comprehensive capabilities in core application scenarios such as battery cell packaging, EPP trays, and foam materials, providing reference for procurement decisions.
