Horizontal bagging machines, sachet machines or flow pack machines from Packaging category are named so in conformity with the product packaging process. Bagging machine creates a plastic tube from a flexible sheet of plastic foil or film. The product then passes through this "sleeve" it until it reaches an edge that delimits the beginning and end of the package.
How Horizontal Bagging Machine Works?
Working principle of a flow pack machine is really quite simple. From a coil carrier shaft, flexible material which can be polypropylene, or any other film-like material according to requirements, passes through a forming tunnel and is soldered by welding wheels. If the coil is not well centered with respect to the axis of the product, the tube formed out of film will have more material on one side than on the other which can cause problems in the final phase of sealing the package. The product itself is pushed by some distant paddles until reaching the plastic film sleeve that has been formed.
Area of Use
Flowpack machines are used to pack solid products only and are closely linked with food industry and food packaging. What kind of products can be packed in a horizontal bagging machines? Think fruits, vegetables, baked goods and even pizza. The length of the package is regulated by a rotating jaw inside the bagging machine which seals the package on both sides of the product.
Once the package size is regulated, the speed of cling film movement needs to be set as well. Keeping in mind that the faster the advance, the longer the package will be obtained. if the cling film is moving too fast and the blades are slower when the product hits them it will cause the tearing of film and will slow down the packaging process.
With the evolution of the technology, the flow pack machines have introduced the electronics for the control of the operations allowing the regulation of all the parameters described above from a digital control panel. The most sophisticated machines are equipped with computer systems allowing to enter the dimensions of the package and the packaging process will be adjusted based on the programming.
Packaging Material Marking
Another basic element of horizontal bagging machines is the centering of the impression of the wrapping material when it has specific graphic marks. For this task the machine is complemented with a photocell that reads some black marks that the material manufacturer performs to determine the beginning and end of the printing area. Nowadays, it is also necessary to mark the date of manufacture or expiration of the product and for this purpose, thermal transfer marking systems or ink jet marking systems are installed on the machines.
Package Shape & Other Requirements
In order to make a more squared package, the "English fold" is used, which is a device that is installed near the blades and is inserted before the welding to increase the dubbing of the plastic. The products most suitable to be packaged with horizontal bagging machines are of average dimensions, not too big. A specific discourse requires the packaging of food products that need to be packaged in a controlled atmosphere to increase the duration as an alternative to the emptying container which is possible in certain types of machines equipped to increase the welding time maintaining temperature and pressure Of the jaws appropriate to the required manufacturing speeds.
