ILTI – Linerless Dispensing module (PROPER-LL1)

3.1 Has the CLS® technology been tested in an industrial production line?Yes, it has.
3.2 What max. speed can be achieved by the CLS® application line?90 meters/minute (500-800 BPM) is the speed of the ILTI Proper-LL1 labelling head available on the market. 130 meters/minute (600-1000 BPM) for the ILTI Proper-LL2 labelling head, which is under development phase.
3.3 Are there any restrictions as to the type of container used?It depends on the container shape, as for the PSA technology. We can work on glass bottles, plastic bottles, cans, etc. Very characteristic shapes always require a prior technical analysis.
3.4 Are there any restrictions as to the materials the containers are made of?No, there aren’t any restrictions . The CLS® technology is an evolution of the PSA technology and the adhesives (contact element between the container and the label) are the same.
3.5 Is it possible to label only bottles/flacons or also rectangular objects?Yes, it is. In general also rectangular objects. As already stated, very characteristic shapes always require a prior technical analysis.
3.6 Is the CLS® technology available only for rotary machines or also for flatbed machines?The ILTI Proper-LL1 and LL2 have been developed for the medium/high speeds offered by rotary machines. They could be inserted also on linear machines, but since the reduced speed of this kind of equipment, a simplified head for low speed is under analysis.
3.7 Shall I mandatorily buy a complete CLS® application machine, or will I be able to buy only the separate labelling unit?It is possible to buy also the only labelling head. The technical characteristics and the compatibility of the host machine have to be verified.
3.8 How long will be the machine downtime for the installation/modification of the CLS® technology?ILTI machines produced for the CLS® can change technology from CLS® to PSA and vice-versa in less than 1 minute per aggregate.
3.9 Will I have to adjust the machine for each label, or is there an electronically retrievable recipe for every size?Yes, recipes for each format are provided (up to 120), no adjustment for the label changeover. All the parameters are stored on memory card.
3.10 Should the dispensing drum be replaced for each different label size or is it adjustable?Yes, this technical solution has been preferred in order to simplify the work of the line operator.
3.11 Is the Non-Stop function available with CLS® labels?Yes, it is.
3.12 Is there an automatic splicing unit for CLS® labels?No, there isn’t. The technical choice is the Non-Stop solution.
3.13 Are only rectangular / square labels possible or also shaped labels?Technically, it is possible to apply shaped labels both on the upper and on the lower part, but it is completely useless thanks to the “No Label Look” material, whereas the shapes will be obtained through the printed graphic design. On the contrary, the die cutting of the material slows down the productive process and increases the cost of the final label in an unjustified way.
3.14 In which markets will the CLS® Technology be available? CLS® will be available worldwide.
3.15 Should the dispensing drum be replaced for each different label size or is it adjustable?Yes, this technical solution has been preferred in order to simplify the work of the line operator.
3.16 Is the Non-Stop function available with CLS® labels?Yes, it is.
3.17 Is there an automatic splicing unit for CLS® labels?No, there isn’t. The technical choice is the Non-Stop solution.
3.18 Are only rectangular / square labels possible or also shaped labels?Technically, it is possible to apply shaped labels both on the upper and on the lower part, but it is completely useless thanks to the “No Label Look” material, whereas the shapes will be obtained through the printed graphic design. On the contrary, the die cutting of the material slows down the productive process and increases the cost of the final label in an unjustified way.
3.19 In which markets will the CLS® Technology be available?CLS® will be available worldwide.
3.20 Who will be in charge of the servicing / installation of the machine?ILTI and its local distributors
3.21 How long will the blades last?Several millios labels. Hardened steel blades. The cost for the replacing of blades is very reasonable.
3.22 If I buy a traditional ILTI machine for PSA labels, will there be any problem to upgrade it to the CLS® Technology?No, there absolutely won’t be any problem.
3.23 Is it possible to have a Bi-Fuel unit, for both PSA and CLS® labels?Yes, it is possible to have a machine with different labelling heads or modular machines with interchangeable labelling heads.
3.24 If I modify my application machine to upgrade it to the CLS® technology, is this modification reversible?In general yes, there are. But it depends on the type of host machine that could have some limitations.
3.25 I am interested in the CLS® technology, I care about the much lower environmental impact, but cannot/will not make investments. Are there possible alternative solutions?No, there aren’t.
3.26 What are the max. and min. thicknesses that the machine can handle?Under 30 micron, but it depends on the material.
3.27 Could the glue of the labels adhere to the cutting edge of the blades hampering their cutting performance?Thanks to the microperforation, the process has a very wide window. Production tests have been performed for 8 hours work, without any need to clean the blades.
3.28 What level of maintenance is needed for the CLS® unit?Standard as per PSA technology.
3.29 What level of maintenance is needed for the dispensing drum?Normal cleaning of the drum and blades.
3.30 What is the turnaround time for the size change of the CLS® unit? How does it compare to a PSA unit?Thanks to the shorter way and the absence of liner, it is much quicker to insert a linerless reel than a PSA reel (30 sec vs. 2 minutes). Replacement of the entire Vacuum drum: about 1 minute.
3.31 Is the cost for a size change equipment of a CLS® unit comparable to that of a PSA unit?No, it isn’t. The CLS® technology requires an additional Vacuum drum that replaces the peeling blade of the PSA technology.
3.32 Is the supply lead time of a size change equipment of a CLS® unit comparable to that of a PSA unit?Yes it is, considering the time for the bottle changeover parts.
3.33 When is the CLS® Technology not usable?On promotional labels or, in any case, on labels with very small dimensions.
3.34 Will the operator need a specific training?Yes, he will need training exactly as for any labelling machine.

General

4.1 I am interested in the CLS® technology and I care about the much lower environmental impact, but do not want to take risks and would like to make some tests and market surveys. Are there any viable solutions?Yes, two dedicated service centers are available at Prati and Ilti to test both finishing and application lines, as well as to produce a first industrial batch.
4.2 If I print and convert my labels with CLS® material using only one printer, how will I manage eventual problems I should face with that company?The CLS® Technology can be used by any printer, provided he avails of a CLS® finishing unit Vega Plus Core.
4.3 Will I be able to keep the same label design using either CLS® technology or traditional PSA technology?Yes.
4.4 I would not like to change my suppcan lier of dispensing machines / I do not wish to deal with Ilti. Where I source an application machine for Core Linerless labels?It can be sourced only from Ilti, the system is patented.
4.5 I have small production volumes, but care a lot about the environment. Can I still use this technology? Will I be penalized financially as opposed to using PSA labels?To assess the financial return on the investment in the CLS® technology, the key is the ratio between the target production volumes and the time needed to fulfill them.
4.6 I have large production volumes. Is this technology reliable? What saving can be forecast as opposed to using PSA labels?The CLS® technology is 100 % reliable. The bigger the volumes, the larger will be the savings and the faster the return on the investments.
4.7 I already have customers that I supply with PSA labels. Why should I produce the same labels for them with CLS® technology? The same labels would benefit from being produced with CLS® technology giving a solution to the Brand Owner as to: - Greatly reduced environmental impact - Much lower cost per label - Enormously enhanced efficiencies - Strong reduction of the logistic costs
