In industrial production and logistics transportation, moisture-proof materials have stringent requirements for the moisture-proof and protective performance of packaging. D Type bulk bags, with their unique structure and adaptability, have become the preferred solution for packaging moisture-proof materials. This article will discuss how to choose suitable type bulk bags for moisture-proof materials. D Type bulk bags, detailing customization for moisture-proof materials. D Key points of type bulk bags.

Moisture-proof materials include electronic component desiccants, food-grade desiccants, building moisture-proof coating raw materials, etc. Different materials have varying requirements for moisture-proofing, damage resistance, and corrosion resistance. For example, electronic desiccants have a high risk of failure when exposed to moisture, and food desiccants have strict hygiene standards requiring targeted design.

First, it is necessary to clarify the temperature and humidity of the transportation route, loading and unloading scenarios (frequency of forklift and crane operations), stacking height, etc. If moisture-proof materials are transported by sea, they must resist high humidity and high salt environments; if stored and transported in cold regions, the bulk bags must also have low-temperature resistance to avoid brittleness and cracking.

Secondly, prioritize high-strength polypropylene ( PP ) woven fabric, which has high tensile strength and wear resistance, ensuring the load-bearing capacity and durability of the bulk bag. For high moisture-proof requirements, multi-layer composite structures can be used. Choose low-density polyethylene ( LDPE ) inner liner bags, which have excellent sealing and moisture-proof properties. If the moisture-proof materials require anti-static or anti-corrosion properties, functional inner liners can be customized, such as adding anti-static agents to the PE film, or acid and alkali resistant polyvinyl chloride ( PVC ) film (note the compliance of food-grade materials).

D The side of the type bulk bag is shaped like a " D " which can increase the effective volume of the bag and distribute stress more evenly. When designing, adjust the height-to-diameter ratio of the bag according to the stacking height of the moisture-proof materials, generally controlling the height-to-diameter ratio between 1.2 - 1.5 , balancing load-bearing and stability to avoid deformation or collapse during stacking.

Reinforce easily worn parts of the bag (such as the bottom and sling connection points) by adding reinforcing fabric, using multiple layers of woven fabric stitched together to enhance local strength; if the moisture-proof materials are sensitive to compression, an elastic support structure (such as an internal plastic frame) can be set inside the bag to maintain the bag's shape and protect the materials from damage.

In woven fabric production, control PP the weaving density of the fabric. High-density weaving can enhance moisture resistance and tensile strength but must balance breathability (except for special moisture-proof materials that require complete sealing).

Customizing type bulk bags for moisture-proof materials D requires deep integration of material characteristics, storage and transportation scenarios, and structural functions. From demand analysis to material science selection, and then to structural and process optimization, every step is crucial to ensuring the quality of moisture-proof materials. Through customized design, D type bulk bags can become a storage and transportation solution for moisture-proof materials, helping enterprises reduce costs and increase efficiency while protecting product value.
