Heavy Duty Plastic Poly Bags - LDPE Food Grade

QIS Packaging's LDPE poly bags are Australia's most complete range of clear, food-grade plastic bags, also known as polythene bags, plastic produce bags, or flat plastic bags. Made from virgin low-density polyethylene (LDPE) for crystal clarity and reliable strength, our poly bags suit everything from light retail and food packing to heavy-duty industrial and freezer use. With 30+ sizes from 75 × 230mm right up to 710 × 915mm and five thicknesses (35µm, 50µm, 75µm, 100µm, and 150µm), there's a poly bag for virtually every job.

Why choose QIS LDPE poly bags?

Every poly bag is manufactured from virgin food-grade LDPE, clear enough to display product and read labels through, strong enough to resist tearing and punctures, and safe for direct food contact. The thicker 75µm, 100µm, and 150µm heavy-duty poly bags stand up to sharp edges, frozen goods, machine parts, and freight handling, while the lighter 35µm and 50µm bags are ideal for high-volume produce, retail, and food-prep use. Bags are open-ended for easy filling and heat-sealing.

Thickness guide

Choose the right gauge for the job, measured in microns (µm):

• 35µm (Standard) – produce, fruit & veg, bread, light retail, high-volume everyday use
• 50µm (Medium) – general-purpose food packing, retail, light storage
• 75µm (Heavy) – heavier products, bulk food, light industrial parts
• 100µm (Heavy Duty) – frozen goods, sharp or heavy items, freight, industrial
• 150µm (Extra Heavy Duty) – the toughest jobs: machinery parts, building materials, heavy freight
