Vacuum Packing removes air from the packets before sealing. This involves placing items in a plastic film package and removing air from inside. Sealer machine is a device used to seal bags and food packets. For most of the products, the effect of packaging and product safety is important for success. There are many sealing quality issues like contamination of product in the sealing area, especially liquid product and loose particles. Preserving food for a longer time means less food spoilage and low wastage of food. Vacuum sealing adds protection layer from external sources and prevents from dehydration. Sealing of food items also helps in maintaining the texture, flavour and moisture of the food inside. It ensures protection from harmful bacteria and moulds that develop on the food.
The Heat sealer machine has a range of up to 350°C having an accuracy of ±1°C. The least count is 0.1°C. The sealing size is 150*15 mm or 300*15 mm. The dwell time is 0.1-99.9 sec with 4 digits digital temperature controller. Heat sensor has pt-100, platinum resistance detector and the sealing pressure is a 2-6 bar. It complies with ASTM F 2029 standards.
