Vacuum Sealing / Vacuum Packaging Guide:
Vacuum packing (or vacuum sealing): a form of packaging that involves the removal
of air (and sometimes its replacement) from a pouch or plastic container.
Vacuum packaging provides several benefits: extension of shelf life; preservation
of flavor; protection against freezer burn; reduction of product shrinkage
(particularly cheese); protection against product dehydration; barrier against
air or moisture; tamper evident protection; compressed packaging for soft goods;
dust and moisture protection for electronic parts
Vacuum Sealer Guide:
Non Chamber Vacuum Sealers:
These units vacuum and seal the pouches externally. Some units also come equipped
with special external nozzles to allow for the vacuum packaging using plastic
containers. Non Chamber Vacuum sealer are meant for low volumes and are suitable
for vacuum sealing products that have little or no moisture. However some units
do have special collectors for products that have excess moisture. Not recommended
for the vacuum sealing liquids, or powered products.
Chamber Vacuum Sealers:
Chamber Vacuum Sealers are designed for sealing higher volumes or products
than their non chamber counterparts. The vacuum pouches are placed within the
box-like chamber, the desired amount of air is pulled from the machine, and
the pouch is then sealed. All of our Chamber vacuum sealers feature stainless
steel construction and are have optional gas flush kits.
Chamber vacuum sealers are an economical solution for high volume vacuum because
the vacuum pouches more economical than the micro layered pouches used in non
chamber sealers. Additionally, chamber vacuum sealers can seal a wider variety
of vacuum pouches and bags. All units include an oil based vacuum pump and
are capable of vacuum sealing meats, fish, dried products, and liquids (using
optional slant tray).
Required maintenance:
Chamber Vacuum Sealers require, routine maintenance. The vacuum pumps are oil
based, so the vacuum oil will need to be routinely replaced. Minipack's vacuum
sealers has a unique feature that indicates when it is time to change the vacuum
oil. Additionally, since these units use an impulse mechanism to heat seal
the pouches, Teflon and seal wires will also need be replaced. We can supply
the vacuum oil, Teflon tape and sealing wire for you chamber vacuum sealer.'
Vacuum Sealer options:
External Vacuum Kit:
This is a special external hose kit that lets users connect their non chamber
vacuum sealer to vacuum seal plastic vacuum containers or the vacuum bottle
caps and lids.
Slant tray for liquids:
A special metal frame designed to facilitate the vacuum sealing of liquids
withing a chamber vacuum sealer. Designed with a slanting body to prevent spills,
these trays have adjustable guides to accommodate numerous bad sizes. These
trays are made from stainless steel
Inert Gas Kit:
Also know as gas flush, this is special adapter for vacuum sealers that let
the users modify the atmosphere within their vacuum pouches. The gas kit would
be needed for in situations where products such as potato salad, beef jerky,
or peanuts needs to be in a vacuum state without compromising the integrity
and visual appeal of the product. Inert gas injected into a package allows
the package to obtain a 'pillow effect' or a vacuum packaging of the product
without the tight rigid package that may destroy or compromise the product.
Seal bar options:
The Minipack Chamber Vacuum Sealers feature a comes with a seal bar consisting
of one 4mm seal wire and a trimmer wire.
However other seal configurations are available including: Double seal : one
bar with two 4mm seal wires; Wide seal: One bar with 6mm bar
Vacuum Pouch Supply Guide
Vacuum Pouches
Also known as food vacuum pouches or barrier pouches, provide a barrier against
atmosphere and moisture.
Vacuum Pouches for Non-Chamber Machines
These pouches are designed specifically for machines that perform an external
vacuum. The micro layered vacuum bags are made from food grade plastic material.
Each pouch consist of 3 layers of construction:
- 2 smooth layers of 3mil polyamide(nylon)-polyethylene barrier material
- 1 polyethylene mesh layer of material in the middle of the pouch. The
mesh middle layer is the most important component of the pouch. It allows
the air inside the pouch to be directly vacuumed out of the pouch.
Vacuum Pouches for Chamber Machines:
These pouches are compatible with chamber vacuum sealers. They consist of
2 smooth layers of 3mil polyamide(nylon)-polyethylene barrier material. 3mil
is the most common thickness for vacuum pouches in the industry and meet
USDA standards for food packaging. These pouches do not have a layer of mesh since the chamber vacuum machines will evacuate
the air once the pouch is within the chamber. Other thickness' available
upon request.
Other Types of Vacuum Pouches:
There are other special vacuum pouches including light barrier bags, boilable
vacuum pouches, and bone guard pouches. Please call for more information.
Vacuum Containers:
These high barrier, and durable plastic containers are an excellent choice
when the application requires a durable vacuum storage. Our vacuum containers
are microwave and dishwasher safe.
Vacuum Bottle Caps:
Minipack has developed a special bottle cap that can be used with their non
chamber vacuum sealers as a solution to preserve flavor and carbonation of
your wines and champagnes.

Vacuum Packaging machines are used to evacuate air around perishable goods such as food products, for short and long term preservation. These machines are also used for packaging vegetables, meats, fruits, liquids and other perishable items. They are ideal for any application where the extension of a product's shelf life, or water/air barrier protection is essential.
Vacuum sealers remove air from a package and seal it. In addition to preserving freshness, sealing in vacuum chamber machines can delay the ripening of fruits or reduce the shrinkage in cheese. The chamber sizes vary greatly in length, width and depth to accommodate packages as small as six ounces or as large as a side of beef. Vacuum packaging supplies include nylon-poly barrier pouches, sealing options like external gas kits and liquid trays, replacement parts, and accessories to complete sealing application requirements.
For applications where the air needs to be replaced, an optional inert gas kit enables the replacement of air with another gas or mixture.
