If you’re new to vacuum packaging and unsure where to start, this is the most important FAQ you’ll read. The #1 mistake first
time buyers make is either over-specifying (buying industrial capacity they don’t need) or under-specifying (buying a
consumer nozzle sealer that can’t handle their actual product). Here’s how to cut through the noise.
Answer These 3 Questions First:
Question 1: Does your product contain any liquid, marinade, or moisture?
Yes → You need a chamber vacuum sealer. This is non-negotiable. An external nozzle sealer will be damaged by liquid
ingestion within weeks.
No → Both chamber and external nozzle sealers are viable. Continue to Question 2.
Question 2: How many bags do you need to seal per day?
Under 50 bags/day → An external nozzle sealer or entry-level single-chamber machine is sufficient. Don’t over-invest.
50–300 bags/day → A single-chamber machine in the DZ-400 to DZ-500 range is the right starting point.
300+ bags/day from day one → Start with a double-chamber. It will cost more upfront but will not become a bottleneck.
Question 3: What is your product’s bag size?
Bags under 400mm wide → Any standard single-chamber handles this
Bags 400–600mm wide → Specify chamber width carefully; most mid-range machines top out at 500mm
Bags over 600mm wide → External nozzle sealer or a large-format chamber machine is required

What to Avoid as a First-Time Buyer:

Avoid machines without an oil-sealed rotary vane pump if you intend to seal wet or high-moisture products. Dry-vane or
diaphragm pumps cannot reach -90 kPa and degrade rapidly with any moisture exposure.
Avoid machines that don’t specify the pump manufacturer or pump displacement (m³/h). This is always a signal that
the pump is a low-grade OEM component without traceable specs.
Avoid the cheapest option in any category. In vacuum sealers, the pump and transformer are the components that
determine real-world lifespan — and they are invisible from the outside. Price reflects component quality more directly in
this product category than almost any other.
