Vacuum packing is a method of packing in which all air is removed from the package prior to sealing.
This method involves placing items in a plastic film package, removing air from inside, and sealing the package. In some cases, shrink film is used to seal the package effectively. The intent of vacuum packing is to remove any air or oxygen in the plastic container to extend the shelf life of food contained in the plastic container, and to reduce the volumes of the content and packaging.
Vacuum sealing is also used in industrial packing to reduce the space that goods or products use during storage and shipping. This considerably reduces freight charges while transporting goods from one place to another.
Instruments used for vacuum packing include heat sealers for plastic bags, which are designed to rapidly seal plastic bags for industry. There are two broad variants of heat sealers namely, the impulse heat sealer and the constant heat sealer. Each heat sealer has its own characteristics.
If you are looking for hand held bag sealer, you are in the right place. Hand held sealers are available for sale through online portals, who offer high quality precision instruments for sale through their online portals.
There are many kinds of impulse sealers available and interested customers should be able to find a machine which would suit their purpose, online.
Impulse heat sealer: These kinds of sealers are quite common in the industry. It works by applying an electrical impulse through a wire located in the jaw of the sealer. This charge should be applied when the jaws are placed on the plastic bag for sealing. This causes the plastic bag to melt and seals itself when this impulse is applied. The width of the seal depends on the width of the jaw and comes in sizes of 2mm, 5 mm and 10mm.
Constant heat sealer: A constant heat sealer for bags is used for special types of plastic bags. It is used to seal plastics with a higher melting point. Smaller hand held sealers are more of the constant type.
For higher seal quality, several test methods are applied to measure the strength of heat seals. In addition, package testing is also carried out by packaging engineers to determine the pressure the packages can withstand pressure in the packing environment. Heat sealing processes are maintained by a variety of quality control systems which constantly monitor and suggest changes to the packing process.
Some of the common applications of heat sealing are as follows:
(1) Heat sealing is used during manufacture of LEDs and LCDs, as well as in medical and telecommunication devices.
(2) It is also used during production of medical and fluid bags in medical, bioengineering and food industries.
