Rotary vs Flat-Bed Die Cutting
There is little doubt that the Rotary Die-Cutter has traditionally been the industry standard for die-cutting printed boxes in large volumes. As the packaging landscape changes it is important to note the current trends in packaging and the implications on your machinery purchasing decisions. There are certainly many reasons to now ask if the Rotary or Flat-Bed is the right tool for your job. Below we will outline some of the reasons for investing in Flat-Bed Die Cutting.
More and more customers are looking to migrate their packaging from 2 or 3 color flexo to high graphic packaging, we will look at shelf-ready packaging as a separate topic, but all the trends out of Europe show us that this is a shift in the market that will follow through to Asia. Whether the high quality printing is done via sheet fed flexo or via Lithographic print laminated onto corrugated board, high graphic printing presents unique challenges when it comes to Die-Cutting.
In 2000 Flatbed Die Cut only represent 10% of the total diecut products, but now more than 60% of Corrugated are done in Flatbed Diecut.
All beer and beverage such as Wahaha (the main beverage in China) also diecut by flatbed Die Cut.
- Because this is the best economical solution as the quality is better and very necessary for the auto filling on the consumer goods.
- The finish product is lean and clean, no need for manual stripping which mean reduce manpower.
- Production output for predictable.
High quality printing is often varnished, when putting this type of material through a Rotary die-cutter, the weight of the pile of board in the feeder along with the gate and feed rollers will more often than not mark the varnish producing a sub par result. The PE-1620-SL-Extra from Brausse Eterna has a special “Zero Scuff” feeder to ensure the sheet looks as good coming out of the machine as it went in.
High Quality printing almost always require a very precise registration of the print to the die-cut, with quite often almost no bleed. This is an area where the Rotary simply has no control. The Brausse-Eterna “L-EXTRA” series die-cutters boast a front and side lay registration along with a Servo controlled delivery table to ensure perfect registration on every sheet.
When clay coated board is Rotary Die-Cut it has a tendency to crack along the creases, as does varnish that’s applied to the board. Flat-Bed Die-Cutters allow the use of “Channel matrix” on the cutting creases that form the creases taking the stress out of the fold and greatly reducing cracking.
As mentioned above, shelf-ready packaging is coming to our markets. As well as the issues related to high graphic printing mentioned above there are also other intricacies that apply to Die-Cutting Shelf-ready packing.
It’s notoriously difficult to stack a complex interlocked job off the back of a Rotary Die-cutter without a large investment in handling equipment. Shelf-ready packaging often entails 4 or 6 up from a sheet The Flat-bed die-cutter is able to effortlessly stack these bundles onto either a pallet or neat bundles.
More and more customers are looking to incorporate easy opening devices into their cartons. These can be in the form of Perforations, zipper rule or similar. The Rotary Die-Cutter uses a soft anvil for cutting, this makes fine perforations impossible and Easy opening devices often tear or fail. Flat-Bed Diecutting is steel against steel, this makes very fine perfing down to 1mm achievable for a carton that performs every time for the customer.
On a Rotary Die-Cutter, stripping is not an exact science, if the tooling is in good condition we should be able to remove the majority of waste with the die or an additional beating section. Flat-Bed Die-Cutting utilises a male and female tool that ensure that every piece of waste no matter how fine can be ejected from the job. It is very common now for food manufacturers to be quite concerned about the possibility of stripping waste ending up in their food product and will reject pallets where even one small piece of scrap waste is visible.
On average Flat-Bed die-cutting formes are 2 to 3 times cheaper than tooling for a Rotary Die-Cutter. This is an important fact to consider, especially on short-run jobs where the cost of tooling can be greater than that of materials and labor.
