Wheat Flour Packaging Bags
Polypropylene Flour Bags
Dhanshri Polypack specializes in PP wheat flour packaging bags that provide strength, food safety, and maximum shelf life for flours. Our polypropylene flour bags deliver optimal performance tailored to your needs.
Introduction to Flour Bags
Polypropylene (PP) woven bags are extensively used for packaging wheat and other flour. PP is a plastic material that offers high tensile strength, chemical and moisture resistance, the ability to withstand high temperatures, and food-grade properties. These characteristics make PP an ideal material for manufacturing flour packaging bags.
PP bags provide the strength to carry heavy loads of flour without failing or tearing. The moisture barrier properties prevent moisture ingress which can cause flour caking during storage and transport. PP can withstand high temperatures allowing heat-sealing processes during bag manufacturing. Chemical resistance allows usage with a wide range of flours. PP is approved for food contact.
Types of Flour Bags
We offer a comprehensive range of flour bags tailored to meet packaging requirements:
- Plain PP Bags – Unprinted, economical bags for packaging flour.
- Printed PP Bags – Custom printed with logos, branding, and product information.
- Laminated PP Bags – Coated with LDPE for added strength and shelf life.
- PP Bags with Handles – Sewn handles for convenient lifting and portability.
- Valve PP Bags – Bags with degassing valves for automatic filling on form-fill-seal machines.
- Pinch Bottom Bags – For manual filling with sewn pinch bottom style.
Bags are available in different shapes, sizes, capacities, thicknesses, and custom prints. We can manufacture PP bags from 100-gram capacity to 50-kg capacity.
Benefits of Wheat Flour Packaging
Key benefits offered by flour packaging bags:
- High tensile strength to carry heavy loads up to 50 kg without failure.
- Moisture barrier retains flour freshness and prevents caking.
- Withstand temperatures up to 100°C allowing heat sealing during manufacturing.
- Chemically inert – does not react with flour contents.
- Food grade and non-toxic material approved for direct food contact.
- Shelf life of 12-18 months for retaining flour quality.
- Able to vent gases released by freshly milled flour.
- Custom printing is possible for branding and marketing.
- Cost-effective compared to other bag materials.

PP vs HDPE Flour Bags
Polypropylene (PP) and High-Density Polyethylene (HDPE) both can be used for flour packaging bags. Key differences:
- PP has higher tensile strength – can carry heavier loads than HDPE without tearing.
- PP provides better heat resistance – can withstand high temperatures during manufacturing.
- HDPE is more flexible and pliable than PP.
- PP has a low moisture vapor transmission rate offering a better barrier against humidity.
- HDPE is more translucent whereas PP is opaque.
- PP is more suitable for heavy loads like 25-50 kg bulk flour bags.
Printing Options
To promote your brand, we offer the following printing options on PP flour bags:
- Flexographic Printing: 1 to 8 colors printing is ideal for long and medium runs.
- Rotogravure Printing: High-quality printing with up to 10 colors.
- Digital Printing: For small batches and prototype samples.
Vibrant colors, logos, and product information can be effectively printed on flour bags as per the design.
