Ad-Star Block Bottom Bag

Saifi Polypack Pvt. Ltd. is a trusted manufacturer and supplier of Ad-Star Block Bottom Bags, Block Bottom Valve Bags, PP Woven Block Bottom Bags and Open Mouth Block Bottom Bags designed for the safe, efficient and attractive packaging of bulk and powdered products. These bags are manufactured from high-quality coated polypropylene woven fabric and can be customized according to product requirements, filling systems, bag size, printing and load capacity.

Ad-Star style block bottom bags are specially designed with a brick-shaped, stable block bottom, allowing the filled bag to stand upright and stack efficiently. Valve-type designs are suitable for automated filling systems, while open-mouth versions can be used for applications requiring conventional filling and sealing. Block-bottom construction provides excellent shape retention and makes the bags suitable for transportation, palletization, warehousing and retail presentation.

High-Strength Ad-Star Block Bottom Bags

Our Ad-Star Block Bottom Bags are developed for industries that require strong, durable and reliable packaging. The PP woven construction offers high mechanical strength while the coated surface provides additional protection against moisture and product leakage.

These bags are particularly suitable for packaging products such as cement, white cement, wall putty, gypsum, lime, fertilizers, chemicals, flour, sugar, rice, animal feed, seeds, granules and other free-flowing bulk materials. AD*STAR-type bags are widely used for both industrial and consumer packaging applications.

Key Features of Ad-Star Block Bottom Bags

• Available in valve and open-mouth formats
• Suitable for automatic and manual filling
• Excellent resistance to tearing and breakage

The block-bottom design helps the filled bags maintain a stable upright shape, which can improve stacking efficiency and handling during transportation.

Ad-Star Block Bottom Valve Bags

Our Block Bottom Valve Bags are designed for products that are packed through automatic filling equipment. The valve provides a convenient filling point through which the product is introduced into the bag. During filling, the bag expands into its block shape, helping create a stable and compact package.

Valve bags are especially useful for cement, dry mortar, fertilizers, chemicals, minerals, flour and other powdered or free-flowing products. The valve construction can also help reduce product spillage during filling and handling.

Open Mouth Block Bottom Bags

For customers requiring conventional filling, we also offer Open Mouth Block Bottom Bags. These bags combine the stable block-bottom construction with an open-mouth top suitable for different filling and closing processes.

Open-mouth block-bottom bags can be customized with different dimensions, fabric specifications, printing designs and finishes according to the application.

Material and Construction

Our block bottom bags are manufactured using coated polypropylene (PP) woven fabric. Depending on the application, construction can be customized to achieve the required balance of strength, flexibility, weight, air permeability and product protection.

Optional constructions may include:

• Coated PP woven fabric
• BOPP laminated PP woven fabric
• One-layer or multi-layer construction
• Optional PE or paper liner
• Micro-perforation for controlled air permeability
• Customized valve construction
• Customized top and bottom configuration

The exact material construction is selected according to the product being packed and the customer's filling, transportation and storage requirements.

High-Quality Printing and Branding

Saifi Polypack Pvt. Ltd. provides customized printing options for businesses looking to improve product visibility and brand recognition. Block bottom bags can be manufactured with flexographic printing or high-resolution multi-colour printing, depending on the required design and application.
