In the world of industrial packaging—especially for commodities like cement, fertilizer, and granular chemicals—durability, cost-efficiency, and weather resistance are non-negotiable. Enter the AD Star Bag. This revolutionary packaging solution has taken over industries that need strong, secure, and user-friendly bags. At Simplex Chemo, we manufacture premium AD Star bags with advanced quality and printing options, tailored to support high-volume packaging needs with precision and consistency.
What Are AD Star Bags?
AD Star bags, also known as block bottom valve bags, are a type of polypropylene (PP) woven sack that combines the advantages of paper and plastic packaging. Invented and patented by Starlinger, the AD Star bag uses hot air welding technology instead of stitching, making it leak-proof and dust-free.
The block bottom design allows the bag to sit upright and stack more efficiently, making it ideal for storage and transport. These bags are widely used in the cement, chemical, agricultural, and building materials industries.
Why Are AD Star Bags a Game-Changer?
✅ Stitch-Free, Leak-Proof Design
Unlike traditional stitched PP bags, AD Star bags are welded using hot air. This creates a leak-proof structure, ideal for packing fine powders like cement or flour.
✅ Block Bottom Structure
The block-shaped bottom allows the bag to stand upright, making it easier to stack, transport, and display.
✅ High Load Capacity
Made from laminated woven polypropylene, these bags can carry heavy loads (25–50 kg) without tearing, even in harsh handling conditions.
✅ Moisture and Weather Resistant
Their laminated surface protects against moisture, making them ideal for humid or monsoon climates.
✅ Printable Surface for Branding
The outer surface can be printed in high resolution, allowing companies to promote their branding directly on the packaging.
Applications of AD Star Bags
● Cement and Building Materials
These bags are the preferred choice for cement packaging worldwide. Their durability, shape, and sealing features make them perfect for packing and transporting heavy building materials.
● Fertilizers and Agrochemicals
Due to their leak-proof design, AD Star bags are also ideal for fertilizers, pesticides, and agricultural powders.
● Flour, Grains, and Pulses
The dust-proof nature of these bags helps in maintaining the hygiene of food products during transportation.
● Chemical Powders
For industries handling non-toxic but sensitive materials, AD Star bags help avoid spillage and contamination.
