In the world of industrial, medical, and high-end food storage, clarity and organization are just as important as the seal itself. While a standard bag protects the contents, a Single Zipper Bag with an Integrated Write-on Panel adds a layer of professional traceability that streamlines operations and prevents errors.
As a leading manufacturer, Haidapack specializes in producing high-precision storage solutions that meet the rigorous standards of global retailers and industrial laboratories.
Quality starts with the resin. We utilize 100% virgin Polyethylene (PE), ensuring our bags are non-toxic, odorless, and fully food-grade. This high-purity material provides the "High-Transparency" required for instant item identification, which is critical in fast-paced warehouse or kitchen environments.
The standout feature of this series is the integrated white writing area. These matte panels are engineered to be compatible with any standard pen or marker. This allows for:
Traceability: Labeling "Pack Dates" or "Expiry Dates" for food safety.
Organization: Marking SKU numbers or part names in industrial settings.
Safety: Clearly identifying hazardous or sensitive materials in laboratory use.
A zipper bag is only as good as its closure. Our single-track zippers are precision-engineered for high-frequency use. They maintain a high-strength seal that protects against moisture, dust, and contamination, even after repeated opening and closing.
We offer two distinct thickness categories to ensure you have the right bag for the right task.
Designed for sharp-edged industrial parts or long-term deep freezing where puncture resistance is paramount.
