Food Industry Services - Packaging & Sealing

Commercial food production is a lucrative business in the United Kingdom. The food and animal products services industry has been instrumental in supplementing our nutrition needs and those of the animals we keep. As technology advances, we have had to alter the manner in which we produce process and distribute food products to consumers around the world. This piece breaks down all you need to know about recent developments in the food processing industry.

Commercial Food processing 

The food and animal products services are a highly regulated industry. Any individual or firm interested in venturing in this line of business will have to comply with numerous food safety and health standards. One such law revolves around the sealing and packaging of industrial food. This law requires all manufacturing plants to invest in a sound vacuum sealing machine.

Heat sealing and vacuum packaging explained

Vacuum packing is a process that entails getting rid of air from a container or a bag sealer. The key to successfully packing food products lies in choosing the right sealer for the job. Sealers work by projecting heat to a contact area using a heating bar to wield thermoplastics together. Vacuum packing, on the other hand, entails flushing air out while the product is still in its sealing package. The most common vacuum packaging products include bottles, canisters, plastic bags and jars. 

Types of vacuum packaging machines

The first variation is the Vacuum chamber machine. Here we have two types; single and double vacuum packaging machines. Vacuum chambers sealers require the whole item to be placed in within the sealing equipment. Once the item is in the device, the lid is closed, and all the air is flushed out. The flushing is done by opening an automatic vent to the outside; the pressure generated from this process squeezes all the remaining air from the bag. These machines are ideal for low to medium volume products such as processed meat, chocolates and cheese. 

The advantages of heat and vacuum sealing

Vacuum and heat sealing has numerous advantages the first being offering advanced protection against dehydration and to prevent entry of moisture. Vacuum packaging also vastly improves the shelf life of dry food items such as cereals, nuts, cheese, coffee, dried fish, meat and even potato chips. For items with a shorter shelf life such as vegetables, fresh meat and liquids, vacuum sealing helps to preserve their freshness while preventing the growth of fungi and bacteria.
