There are two types of slitting: log slitting and rewind slitting. In rewind slitting the web is unwound and run through the machine, passing through knives or lasers, before being rewound on one or more shafts to form narrower rolls.

The multiple narrower strips of material may be known as mults short for multiple or pancakes if their diameter is much more than their width. For particularly narrow and thin products, the pancakes become unstable, and then the rewind may be onto a bobbin-wound reel: the rewind bobbins are much wider than the slit width and the web oscillates across the reel as it is rewound.

Apart from the stability benefit it is also then possible to put very long lengths, frequently many tens of kilometresonto one bobbin.

Flexible Packaging Manufacture Process

Several methods are available for soft materials like plastic filmstextilesadhesive tapesand paper. Razor bladesstraight, or circular blades are being used.

Some blades cut through the material while others crush the material against a hard roll. Those are similar to knives. The cutting blades can be set to a desired width.

Some machines have many blades and can produce a number of output rolls at once. The slit material is rewound on paper, plastic or metal cores on the exit side of the machine. The process is used because of its low cost and high precision for mass production. Some machines have a program that monitors the blades and sharpens the blades often to maintain the quality and precision of the cut.

The machines can also incorporate extensive automation to precisely control material tension, automatically position the slitting knives, automatically align the cores onto which the material is wound and to reduce manual handling of the rolls. Examples of materials that can be cut this way are: adhesive tape, foam, rubber, paper products, foil, plastics such as tarps and cling wrapglass cloth, fabrics, release liner and film. For harder materials, such as sheet metalblades cannot be used.

Instead, a modified form of shearing is used. Two cylindrical rolls with matching ribs and grooves are used to cut a large roll into multiple narrower rolls. This continuous production process is economical yet precise; usually more precise than most other cutting processes. However, the occurrence of rough edges known as burrs are commonplace on slit edges.JavaScript seems to be disabled in your browser.

Finishing is the final stage before packaging arrives at your facility, exactly as specified.

Precision cutting or slitting allows many companies to convert different packaging materials, such as tape or plastic film, to a custom size for easier application. Custom-sized products offer many benefits, including reduced product waste, greater design flexibility, and material cost savings. There are many methods of precision cutting and slitting available, so we thought it would be helpful to go over a few of the options for you.

During the rewind slitting process, a master roll is unwound from its original core before it reaches the blades of the slitter. Rewind slitters have the ability to make multiple cuts simultaneously and rewind onto variable core sizes. Lathe slitting is sometimes called log slitting because during the cutting process, an entire master roll is sliced without unwinding the material first.

A large blade cuts into the master roll to create a new roll at the desired width.

This type of slitting provides rapid conversions and can be programed for high-volume production. During a laser cutting application, a controlled high-power laser is used to create a specific shape or cut in a material. Laser cutting is excellent for providing both the quick creation of prototypes and long runs of an infinite variety of parts on one roll for kit creation. Laser cutting provides the benefit of creating highly controlled micro parts, and there are typically little to no tooling costs.

Die cutting allows for the creation of fast and accurate parts in a variety of shapes and sizes. These parts can then be provided on easy to use rolls or as individual sheets.

During the cutting process, a die press is formed into the specific shape and structure you need to enable compression of a material into that shape. Waterjet cutting is ideal when working with certain materials such as foam, metal, stone, composite, or laminate materials. Waterjet cutting rinses away any fine particles that would gather on cut surfaces, which is common with materials like foam.

This helps better protect products that will be packaged in that material, especially if they have easy to scratch surfaces.

Waterjet cutting also eliminates fracturing, chipping, or thermal stress on a material while reducing most finishing operations. A large XYZ Plotter machine is the right solution for large-scale and nested parts that are made from both flexible and rigid materials — without the need for tooling. A computer moves the knife to create the desired outcome.

Back to Top.The company looks for solutions to improve sustainability, such as the microperforation which extends the shelf-life of fruits and vegetables. Comexi, a global leader in the flexible packaging industry, has the most sophisticated slitting and rewinding machines, and it is constantly innovating in order to satisfy the most demanding needs of its customers and final consumers.

The company offers high value solutions thanks to its expertise in laser, such as microperforation, QR codes, easy-open windows, among others, which give converters the turn-key solution and the added benefit of making life easier for the packaging end user.

In recent years, Comexi has developed modular solutions for S1 slitter range, allowing greater automation of both, the slitting process and the process which immediately follows. This can be the case of conveyors, labelling, weighting, bagging, and palletizing.

The result is the optimization of the process and increase of the customer's production. In many cases, the slitter is the final step of the converting process and the last to be in contact with the reels.

However, it will still go through a few changes before reaching the final customer. All this post-converting processes, most of which are related to traceability and protection, can significantly undermine the effectiveness of the company if not handled properly.

Connecting the dots between these processes, through customized automated solutions, can lead to a significant increase in productivity. Mainly this is due to the reduction of downtimes. Uptime can also improve through the integration of online-finishing processes with the slitters. Comexi's laser technology facilitates the creation of easy-open applications in some packages without adding any extra processes.

There is an unimaginable number of alternatives, such as scoring triple-opening lines, shapes, etc.

Additionally, the system allows to create window effects in the package allowing the end consumer to see the contents within the packaging.

This creates a more reliable brand perception with a natural and homemade touch. Many brands have used the laser process to communicate this idea by creating a clear plastic film window on a laminated paper pouch. Concerned about everything related to sustainability, Comexi seeks solutions which contribute to improving the environment.

One of these solutions is microperforation, which extends the shelf-life of fruits and vegetables. The FPA Flexible Packaging Association recently published various studies that indicate the extension of shelf-life as a result of suitable flexible packaging with MAP Modified Atmospheres Packaging : the shelf-life of packaged green beans and grapes increases from 7 to 19 days and 7 to 70 days respectively.

The creation of MAP relates to microperforation, a solution that is also developed with laser integrated with a slitter.
