FAQ about Vacuum Chamber Sealers

FAQ Vacuum Packaging Machines

Can this machine seal foil or laminated bags?
Yes, it is designed to seal barrier laminations including laminations containing foils.

How much longer will my products last?
Typically shelf life may be extended three to five times. Results will vary, though, depending on the nature of the product, cleanliness, handling, temperature, and pre and post packaging conditions, among others.

What type of bag do I need to use?
You need bags capable of offering a full gas barrier. Bags come in different sizes, and minimum order is typically only one thousand bags. Contact of us pricing and availability.

What are the advantages of vacuum packaging my products? Extended shelf-life
No freezer burn
No loss of volume or product weight due to evaporation
Reduced action by aerobic bacteria
Ease keeping control of inventory
Cost-reduction due to volume purchasing of products to be packaged
Capacity of producing in large batches
Excellent product appearance
Increased Product Safety from theft, vandalism and contamination.
Increase ease of product handling
Improved product quality perception from clients and consumers

How do these machines work?
The operator places the bags flat onto the work surface of the machine, putting the mouth of the bag on the bottom seal bar. The vacuum pump engages as the operator lowers the lid of the chamber. Once target vacuum level is achieved the machine automatically seals the bag and lets air re-enter the chamber. On double chamber machines, the operator clears sealed bags and places new ones into the empty chamber while the vacuum process takes place on the filled chamber.

Can I vacuum- pack liquids ?
Absolutely. Many clients use these machines to bag salsa, soups, broths, stocks, and/or consommés.

How do I figure the settings to seal my bags?
Setup is an extremely simple procedure and should take no more than a minute or two. Before you begin read all machine documentation carefully as it includes important safety information. Plug in and turn on Sealer (if applicable). Set up sealing time knob to level one. Put bag in sealer and test. If the bag is not sealed increase sealing timer to the next level. Repeat the process until you get the minimum time necessary to seal your bag.

Do you recommend any parts we should keep in stock? You should keep a few Heating Elements and Teflon Strips, as these have a limited life span. The machines come with a kit of spares, but keep an eye on how many you have left.

If I vacuum package my food products, will I still need to refrigerate them?
Yes, vacuum packaging is not a substitute to refrigeration.

My products cannot handle the crushing pressures I see in vacuum packages.
Are there any options available?
Yes there are options we can offer. By replacing the air inside the bag with inert gases (which will not interact or affect your product in any way), we can achieve the same results of vacuum packaging while eliminating the crushing atmospheric pressures visible in many vacuum packaging applications. The packing process is the same as the one describe above, with the addition of a gas flush or gas injection phase right before sealing the bag. Contact us for more information on the best model for this application as this feature is not standard.

I need something faster than what you are offering here
We offer single and double chamber machines, equipped with single and double seal bars, and different chamber volumes; as well as fully automatic machines designed to cover the most rigorous productions schedules.
