Qnubu Continuous Band Sealer

Sealing a few bags is easy. Sealing hundreds quickly and consistently is where a continuous band sealer really makes the difference.

The Qnubu Continuous Band Sealer is designed for users who need fast, reliable and repeatable packaging. Its continuous operation allows bags to be fed one after another while the machine produces clean, uniform and durable seals without stopping between packages.

It is especially well suited for heat-sealable Mylar bags, one of the most popular packaging formats for flowers, hash, solventless extracts, food products, herbs and spices. Whenever vacuum packaging isn't required, Mylar bags offer a simple and cost-effective solution while providing excellent product protection, especially when paired with a strong seal that helps minimise odour leakage.

Powered by a 450 W heating system, with an adjustable sealing speed of 0 to 17 metres per minute and a temperature range from 0 to 300 °C, the machine easily adapts to different bag materials and thicknesses without sacrificing productivity.

What you'll notice

The first thing you'll notice is the workflow. Instead of manually sealing every bag, you simply feed each package into the machine and let the continuous conveyor do the work. The result is faster production together with consistent, professional-quality seals.

The adjustable 8-12 mm sealing width creates a thick, uniform weld that helps minimise odour leakage while providing a strong, reliable closure—particularly valuable when packaging premium flowers or solventless extracts.

Did you know?

One of the most common mistakes when using a heat sealer is assuming that higher temperatures produce stronger seals. In reality, excessive heat can distort the plastic and weaken the weld. The best approach is to use the lowest temperature that delivers a clean, consistent seal for the specific bag material.
