Flexo Printed Bags
Introduction
Flexo printed woven bags are strong, durable, and customizable packaging solutions widely used across industries such as agriculture, food, chemicals, construction, and retail. These bags are made from woven polypropylene (PP) fabric and printed using flexographic printing technology, which ensures high-quality, cost-effective, and eco-friendly branding. Their wide acceptance is due to their strength, reusability, and attractive presentation.
Raw Material Used
• Polypropylene (PP) granules – primary raw material for woven fabric.
• Master batches – for adding colours to the fabric.
• Laminates / BOPP films – optional, for extra barrier properties and glossy finish.
• Inks for flexographic printing – solvent-based or water-based.
• Additives – for UV resistance, strength, and anti-aging properties.
Types of Bags
• Laminated woven bags – with a film layer for moisture protection.
• Unlaminated woven bags – breathable and cost-effective.
• Gusseted woven bags – allow extra storage capacity.
• Printed shopping bags – lightweight, branded for retail.
DOs and DON’Ts
DOs:
• Choose correct thickness as per product weight.
• Use high-quality inks to ensure durable printing.
• Store bags in dry conditions to avoid moisture damage.
• Ensure proper sealing/stitching for product safety.
DON’Ts:
• Don’t overload beyond the weight-bearing capacity.
• Avoid exposure to direct sunlight for long periods unless UV stabilized.
• Don’t use substandard printing inks that fade quickly.
• Avoid reusing bags for incompatible products (e.g., food vs. chemicals).
Properties and Benefits
• High strength and durability – withstand heavy weights.
• Reusable and recyclable – eco-friendlier than single-use plastics.
• Cost-effective – cheaper than jute or paper for bulk use.
• Water and moisture resistant (especially laminated ones).
• Excellent printability with flexographic technology.
• Customizable in terms of size, thickness, and design.
Fabric Thicknesses
• Typically ranges from 40 GSM to 200 GSM depending on end use.
• Lightweight fabric (40–70 GSM) – retail or shopping bags.
• Medium fabric (80–120 GSM) – agricultural products like rice, flour, seeds.
• Heavy fabric (130–200 GSM) – industrial packaging like cement, fertilizers, chemicals.
Printing Types
• Flexographic printing (Flexo) – common, cost-effective, fast production.
• Rotogravure printing – used for premium, photo-quality prints (on laminated bags).
• Screen printing – suitable for small runs and bold designs.
Branding of Product
Flexo printed woven bags act as mobile advertisements. Clear, vibrant, and durable printing helps in:
• Enhancing brand visibility.
• Showcasing product details and instructions.
• Increasing customer trust and recognition.
• Differentiating products in competitive markets.
Thoughts on Improvising
• Use eco-friendly inks and recyclable laminates to reduce environmental impact.
• Incorporate QR codes or barcodes for digital product tracking.
• Improve aesthetic finishes like matte/gloss, UV coating, or metallic printing.
• Develop biodegradable woven fabrics for sustainable packaging.
• Automate stitching and sealing for consistent quality.
Conclusion
Flexo printed woven bags are a perfect blend of strength, utility, and branding. They provide industries with a reliable packaging solution while offering businesses a platform for cost-effective advertisement. With continuous innovations in eco-friendly materials, printing techniques, and value-added features, these bags will remain one of the most preferred packaging choices in the future.
