18x20 Extra Heavy Duty Tuf-R Flat Poly Bags - Industrial-Strength LLDPE Protection
These 18x20 Tuf-R flat poly bags deliver exceptional puncture resistance and tear strength for demanding industrial applications. Made from 2.75 mil linear low-density polyethylene (LLDPE), they outperform standard LDPE bags of the same thickness, providing superior protection for heavy parts, sharp-edged components, and rough-handled inventory.
Product Specifications

Why Tuf-R LLDPE Outperforms Standard Poly
Tuf-R linear low-density bags use a molecular structure that provides significantly greater stretch and puncture resistance compared to conventional LDPE. This means a 2.75 mil Tuf-R bag often replaces a 4 mil standard poly bag, reducing material costs while maintaining protection levels. The enhanced tear propagation resistance keeps bags intact even when handling sharp corners, metal parts, or abrasive materials.
Industrial Applications
The 18x20 size combined with extra heavy-duty construction makes these bags ideal for:
- Machine Shops: Protecting finished metal components, castings, and fabricated parts from scratches and contamination
- Automotive: Packaging replacement parts, gasket sets, brake components, and service kits
- Warehouse Operations: Organizing inventory, kitting assembly components, and protecting stored materials from dust and moisture
- Manufacturing: Work-in-process protection, inter-facility shipping, and quality control sampling
- Tool Storage: Keeping hand tools, power tool accessories, and maintenance equipment organized and protected
Key Features
- Superior Puncture Resistance: LLDPE molecular structure resists penetration from sharp edges and pointed objects
- High Tear Strength: Resists tear propagation even when stressed or overloaded
- Virgin Material Construction: FDA compliant for food-contact applications when needed
- Downgauge Potential: Replace heavier LDPE bags with lighter Tuf-R for cost savings
- Crystal Clear: Easy visual identification of contents without opening
Packaging & Storage
Bags ship flat-packed in cases of 500 units. Store in a cool, dry environment away from direct sunlight to maintain optimal clarity and performance. The generous 18x20 opening accommodates bulky items up to approximately 17x19 inches with allowance for heat sealing or tie closure.
