Any commercial food processing unit cannot function without packaging machines. It locks and seals in the freshness of the food materials. Apart from that, packaging also caters to other manufacturing jobs like labeling, metal detection etc
There are numerous varieties of food packaging machines available in the market to fulfill your needs. Your choice will depend on the type of the food that you need to pack.

Food Packaging Machines – Techniques, and Types
VACUUM PACKAGING – This is the most efficient and popular form of packaging. Processed meats and frozen foods are packed and sealed using this technique. When perishable items are vacuum packed it gives them a longer shelf life. The packaging draws out all the air, which helps to preserve the food and retain the freshness.
TRAY SEALERS – These machines are very important to the packaging division. Tray sealers are used to seal trays by putting a film on the trays. There are manual, semi-automatic and fully automatic tray sealers available at any reputable supplier.
LABELING MACHINES – The name itself explains the job of these machines. They are used to label jars, bottles, boxes, cartons, cans, tubes etc. Any and every kind of food processing plant needs this equipment.

MACHINE WARRANTY AND REPAIRS
Warranty of the machine is very important. You need to ask the dealer about the warranty period, replacement policies, and repair needs. Get a crystal clear idea about the above-mentioned clauses.
