As there are many varieties of liquids and gels available in the market, the machinery used to store them into containers is also wide-ranging. Depending upon the usage of certain products, industries utilize various types of packaging methodologies to enhance their product quality. However, not following the required series of technical steps or missing a single point of packaging accuracy can lead to faulty results and contamination of a product. So, it is crucial to have a basic knowledge of the sequence of filling and sealing liquids in a container during the packing process, so you can avoid any harm or damage in the end.
Let us take a glance upon the points describing what types of discretion required in the liquid packaging process :
Cleaning the containers
Generally, the containers come in contact with dust particles during the packaging process which can spoil the quality. As the products need to remain pure for their intended usage, the step of cleaning them is also very significant. To remove the filth from the body of a container, often a rinsing machine is used. Additionally, some manufacturers also use bottle vacuum, wet rinser, and air rinser for this purpose.
The construction material of the appliance
Several types of filling machines are used to pour liquid products into cans or bottles. To avoid any harm to a sensitive product and its packing body from the chemical reactions resultant of filling machines, the construction material of the appliance is selected with great care. For example, in many manufacturing plants, HDPE material is used to evade corrosion on the filling equipment made of steel. This also helps enhance the life of machinery.
Suitable selection of capping technique
A capping machine is selected according to the forms of different liquids and their specific closure types. There are various varieties of closures such as snap caps, spouts, fixtures, unique closures, screw-on cap, etc. Sometimes, capping techniques are modified for specific types of cappers. This is often necessary to protect the product from a hazardous environment.
Fluids that require compressed air or nitrogen in their packing process, appeal to special sealing techniques. The bag on valve system proves exceptionally useful in such conditions as it contains a multi-layered flexible pouch connected to an aerosol valve which is easily crimped into the can consisting of compressed air. This modern packing technique is exceptionally convenient to improve the packaging quality of pharmaceutical, cosmetic, and medical products.
Labeling a product
Once the product is sealed in the bottles or cans, labeling equipment applies labels in various manners and formats. As the product is already packed and sealed, there is a limited need for modifying the labeler. It is required in rare cases such as when a strident product creates a perilous environment.
The type of packaging machines and their process of packing depends upon the level of production. In small scale industries where the level of production is low, simple tabletop equipment is used whereas in large industries, the appliances are automated with a power conveyor.
