Product Description
The multi-layer valve bag is crafted using fully wood pulp bleached kraft paper as the core material. It undergoes a sophisticated multi-layer composite process, resulting in a high-quality sealed packaging container equipped with a professional valve structure.
This product combines the load-bearing and protective properties of multiple material layers with the convenient sealing advantages of the valve design. Compared to traditional open-mouth bags, it does not require additional sewing or tying. Once filled, the bag can automatically seal itself.
Such features not only enhance operational efficiency and material protection but also support customized printing. This allows for a triple improvement in practicality, airtightness, and brand presentation, making it a superior packaging solution.
