Shandong Haoyu’s plastic seals are gaining popularity among e-commerce platforms and food distributors for their lightweight durability and affordability. Made from reinforced polypropylene, these seals resist extreme temperatures and UV exposure, ensuring reliability in outdoor storage or long-haul shipping. Unlike metal seals, they leave no residue when cut, streamlining recycling processes. A leading Asian logistics provider reduced packaging costs by 25% by switching to Haoyu’s plastic seals for non-sensitive cargo.
