BOPP bags have become a preferred packaging choice for industries like food grains, fertilizers, animal feed, seeds, and consumer products — not only because they are strong and durable, but because they offer premium branding opportunities with high-quality graphics.
At Anita Plastics, we manufacture BOPP laminated woven bags using a fully integrated, state-of-the-art production process. With 45+ years of expertise, 14 advanced manufacturing facilities, and a production capacity of 5,000+ MT per month, we ensure that every BOPP bag delivers strength, clarity, print precision, and consistency.
Polymer Extrusion – Creating Strong PP Tapes
The process begins with Polypropylene (PP) granules, a lightweight and durable polymer ideal for woven packaging.
Steps Involved
- PP granules are fed into an extrusion line.
- They are melted and extruded into thin sheets.
- These sheets are slit into PP tapes.
- The tapes are stretched (oriented) for strength and elasticity.
Why It Matters:
High-quality tapes = stronger woven fabric = better tear resistance.
At Anita Plastics, our extrusion lines are engineered to produce consistent, high-tensile PP tapes, ensuring durability in every bag.

Weaving the Fabric – Creating the PP Woven Base
The PP tapes are then loaded into circular or flat weaving looms.
Key Outputs
- PP woven fabric rolls
- Controlled GSM (Gram per Square Meter)
- Uniform weave patterns
- High burst and tensile strength
We produce custom fabrics depending on the client’s required GSM, strength grade, and application.
BOPP Film Printing – Bringing Branding to Life
This step is where the bag’s visual identity comes alive.
Printing Process at Anita Plastics
- High-definition rotogravure or flexographic printing
- Up to 4 colors (or more upon request)
- Reverse printing on BOPP film for scratch resistance
- Excellent clarity, color depth, and photographic quality
Why It Matters
Printing on BOPP film ensures the design remains protected beneath the laminated layer, maintaining brand visibility throughout logistics, handling, and shelf presence.

Lamination – Bonding BOPP Film to Woven Fabric
Printed BOPP film is laminated onto the PP woven fabric using extrusion lamination technology.
Benefits of Lamination:
- Superior moisture protection
- Enhanced print longevity
- Increased bag strength
- Smooth or matte finish options
- Improved product shelf life
Anita Plastics offers glossy, matte, and hybrid lamination finishes to match brand aesthetics.
Fabric Cutting & Conversion – Preparing Bag Panels
Once laminated, the fabric roll is passed through automatic cutting machines.
Conversion Includes
- Cutting fabric panels to required sizes
- Heat cutting to prevent frayed edges
- Preparing front, back, side gussets (if needed)
Bag dimensions are customized based on the client’s product, filling weight, and branding needs.
Bottom Stitching or Hemming – Structuring the Bag
The cut pieces are stitched using industrial sewing machines.
Common Options
- Single/double-stitch bottom seam
- Folded & hemmed top edges
- Valve-type construction (for fertilizers, powders)
- Pinch-bottom options
At Anita Plastics, all stitching is reinforced to ensure each bag withstands heavy loads during filling, stacking, and transportation.

Gusseting – Adding Shape & Stability (Optional)
Some BOPP bags require gussets to increase volume and improve stacking.
We offer
- Side gusset bags
- Pinch gusset bags
- Block-bottom construction
These features improve shelf presence, making the bag stand upright — especially beneficial for branded retail packaging.
Micro Perforation – Ensuring Breathability (As Needed)
Products like flour, seeds, and animal feed require airflow.
Micro perforation offers
- Moisture release
- Preventing condensation
- Better product freshness
We customize micro-perf patterns depending on the product type.
Finishing, Quality Check & Inspection
Every bag passes through a multi-level inspection process, including:
- GSM verification
- Print clarity check
- Strength and seam testing
- Lamination bond evaluation
- Dimensional accuracy
- Visual inspection for defects
At Anita Plastics, quality is engineered at every step — not just checked at the end.
Packing & Palletization – Preparing for Container Shipments
After inspection, bags are stacked, pressed, and packed.
Options include:
- Bale packing
- Pallet packing
- Shrink wrapping
- Custom export packaging
We optimize the packing method to ensure maximum quantity per container while protecting product integrity during transport.
