75µm Heavy Duty Resealable Bags

QIS Packaging's 75µm heavy-duty resealable bags are built for the tougher jobs. At 75µm thick (50% thicker than the standard 50µm) these clear LDPE press-seal bags resist punctures, tears, and rough handling far better than everyday resealable bags, making them ideal for storing heavy, sharp, or abrasive items. Choose from 16 sizes spanning 50×75mm right up to 380×510mm, in both standard press-seal and premium Maxigrip bottom-loading styles.

Why choose 75µm heavy-duty resealable bags?

When standard resealable bags split or puncture, 75µm bags keep their integrity. The thicker LDPE film handles the weight and sharp edges of nuts, bolts, tools, hardware, machine parts, and frozen or bulk food without tearing, while the strong press seal keeps moisture, dust, and air out. Crystal-clear film lets you (and warehouse pickers) identify contents instantly, and the reliable zip opens and closes hundreds of times without losing grip.
