Quality – Industrial Grade Packaging

Our industrial-grade packaging solutions are engineered for strength, reliability, and durability across the most demanding applications. At Crown Bags LLC, every bag is produced with strict material discipline, advanced reinforcement techniques, and multi-level quality checks to ensure zero breakage, zero leakage, and maximum performance during handling, filling, transport, and storage.

100% Virgin Polypropylene for Maximum Strength

We use only 100% virgin PP, ensuring:

  • Higher tensile and tear strength
  • Superior load-bearing capacity
  • Longer shelf life
  • Better performance under extreme industrial conditions

Virgin material eliminates impurities and offers consistent performance that recycled blends cannot match.

Optimized Calcium Filler – Max 8%

Our industrial-grade fabric uses:

  • Maximum 8% calcium filler
  • Ensuring optimal combination of flexibility + strength
  • Preventing brittleness, cracking, or premature tearing

Low filler content keeps the tape strength high and helps maintain bag integrity even under heavy loads.

2% UV Protection – Outdoor Safe

Every industrial bag is UV-stabilized with 2% UV masterbatch, enabling:

  • Protection against sunlight degradation
  • Safe outdoor storage
  • Longer fabric life without weakening or discoloration

This is critical for customers storing bags in open yards or exposed conditions.

No Breakage – Engineered for Reliability

We design every bag with:

  • High denier tapes
  • Optimized weave density
  • Reinforced stitching
  • Strong lifting loops
  • Balanced GSM for body, top, and bottom panels

This ensures safe lifting, stacking, and transport with zero breakage even under maximum load conditions.

Advanced Dust-Proofing Systems – No Leakage

To eliminate product leakage during filling and handling, our industrial bags incorporate:

  • Dust-proof seams
  • Filler cord sealing
  • Tape lamination sealing
  • Multi-level stitching control
  • Option for ultrasonic sealing (where required)

These systems ensure no dust escape, especially for fine powders, chemicals, minerals, carbon, resins, and other flowable materials.

Wide Range of Liner Options

For moisture barrier, odor control, or chemical resistance, we provide:

  • Loose liners
  • Shaped liners
  • EVOH barrier liners
  • Aluminium foil liners
  • Gusseted, form-fit, or custom liners

Each liner is selected based on product type, density, and protection requirements.

Complete Quality Checking – Every Stage

Our industrial-grade QC system covers:

  • Fabric tensile strength testing
  • UV degradation testing
  • Tape elongation & break strength
  • Loop strength verification
  • Drop tests
  • Weave density inspection
  • GSM consistency checks
  • Stitch quality control
  • Final load testing
  • AQL-based sampling

No bag passes through without clearance from our QC team.

Corona Treatment for Anti-De-Lamination

To improve print adhesion and prevent delamination:

  • All coated fabrics undergo corona treatment
  • Ensures strong bonding between coating & fabric
  • Prevents peeling and bubble formation in harsh conditions

This is critical for customers using printed or laminated bags.

Advanced Laboratory Equipment

Our in-house lab is equipped with the latest testing machines, including:

  • Tensile strength testers
  • UV aging chambers
  • GSM cutters
  • Bursting strength testers
  • Melt flow index testers
  • COF analyzers
  • Thickness & elongation testers

This ensures every batch meets repeatable, certified industrial standards.
