In international agricultural supply chains and demanding industrial packaging applications—ranging from delicate greenhouse produce (prickly cucumbers, eggplants, bell peppers, zucchini, tomatoes) to greasy cast iron fittings, bulk textile rolls, and masterbatch pellets—heavy-duty transparent polyethylene bags with leak-proof thermal seals are essential. SherkatTrade Heavy-Duty Flat PE Bags (Cucumber & Industrial Bags) are manufactured using cutting-edge multi-layer co-extrusion technology, engineered to meet the stringent export and transit standards of the Middle East, Central Asia, Russia, and Eastern Europe.
Our proprietary formulation blends 100% virgin Low-Density Polyethylene (LDPE 0075 / 0209) with precision-calibrated Linear Low-Density Polyethylene (LLDPE 209AA). This composite structure delivers unmatched Dart Drop impact resistance and puncture protection against sharp vegetable stalks and jagged metal edges, while maintaining crystal-clear optical clarity that elevates produce appeal on wholesale trading floors.

| Industry & Sector | Recommended Size & Thickness | Packaging Application | Strategic Benefit |
|---|---|---|---|
| Greenhouse Ag (Cucumbers, Peppers) | 40x60 cm, 50x80 cm (45 - 60 µm) | Vegetable sorting and export packing | Retains moisture, prevents wilting, and showcases premium quality |
| Machined Parts, Fasteners & Foundry | 50x70 cm, 60x90 cm (90 - 120 µm) | Greasy bolts, valves, and hardware | High puncture resistance against sharp burrs and industrial lubricants |
| Textiles, Fabrics & Apparel | 80x120 cm, 100x150 cm (50 - 70 µm) | Textile bolts, yarn cones, bulk clothing | Complete barrier against warehouse dust, grime, and atmospheric humidity |
| Organic Fertilizers & Potting Soils | 50x80 cm, 60x90 cm (80 - 110 µm) | Compost, peat moss, soil amendments | Chemical resistance against organic acids and enduring moisture barriers |
| Bulk Dry Foods & Ingredients | 40x60 cm, 60x100 cm (60 - 80 µm) | Pulses, dried fruits, sugar, grains | Food-grade compliance, aroma preservation, and hermetic isolation |
Formulated with high-purity optical clarifiers that exceed 92% light transmittance, ensuring that fresh produce looks vibrant and pristine. This accelerates customs verification and attracts premium retail buyers.
Our state-of-the-art sealing bars feature digital PID temperature controls that weld the polymer chains into a single homogeneous seam. In drop tests from 2.0 meters carrying 25 kg loads, our bags demonstrate a 100% survival rate.
Precision dosing of food-grade erucamide slip agents eliminates surface friction, allowing packing line workers to snap open bags instantaneously, boosting sorting line throughput by up to 30%.
Clean-cut circular punch holes expel trapped air instantly when bags are packed into wooden or plastic crates, preventing produce sweating and inhibiting bacterial rot in cold storage.
SherkatTrade bags use 100% virgin polymer resins, ensuring crystal transparency, zero foul odor, high mechanical elasticity, and food-grade compliance. Recycled bags suffer from polymer degradation, haziness, unpleasant chemical odors, and sudden tearing.
For payloads between 10-15 kg, a thickness of 40-50 microns is ideal. For standard 20-25 kg agricultural sacks, 60-80 microns is recommended. For heavy industrial hardware up to 50 kg, we recommend 100-120 microns.
Yes. We manufacture custom widths up to 150 cm and offer up to 4-color flexographic printing for company branding, barcoding, and regulatory product labeling.
Bags are counted precisely, bundled in packs of 50 or 100, and packed into heavy-duty woven PP bales to ensure zero transit damage. Direct container and truckload dispatches originate from our Isfahan manufacturing complex.
