Comparison Peach Sky 335R6 vs Bulros PDA3-330TD

The maximum laminating speed provided by the device — in other words, the length of the section that the laminator is able to laminate in a minute. The high speed rate makes it easier to operate with large volumes of media, but significantly affects the cost of the device. Therefore, it makes sense to look for a quick laminator only if you have to deal with large volumes of media, or if the ability to quickly handle the task is critical. If the device is bought for use from time to time, this indicator can be ignored.

The thinnest film (in microns) that the laminator can handle.

Different applications require different types of film; a thin film can be useful for laminating thin sheets of paper or if you need to maintain the flexibility of the material. Detailed recommendations about the optimal film thickness for a specific type of work can be found in special sources. The most popular are films with a thickness of 75 and 80 µm. There is also an intermediate type with thickness of 60 µm.

The thickest media the laminator is capable of operating with.

If choosing the device is based on this spec, it makes sense not only to take into account the thickness of the media is being to operate with, but also to take a certain margin just in case. At the same time, we note that even the "thinnest" modern laminators are capable of processing materials up to 0.2 – 0.3 mm thick — this is comparable to thin cardboard or very thick paper. And in high-end professional models, this value can exceed 10 mm.

The number of rollers provided in the design of the laminator. The rollers perform two main functions — the supply of the media to be laminated and the pressure necessary to fix the film. In addition, in many modern laminators, rollers also play the role of heaters within a heated laminating type (see "Type of lamination").

The rollers are installed exclusively in pairs, so the smallest number is 2. A larger number of rollers allows you to achieve better uniformity of movement and, accordingly, the quality of processing, and also allows you to work with thicker films; on the other hand, it also affects the price of the device. Therefore, most entry-level and mid-level laminators have 4 rollers (2 pairs), and in professional models this number can reach 8.

The time it takes for a hot laminating device (see «Laminating Type») to reach operating temperature.

The shorter this time, the more convenient the laminator to use, but the more energy it consumes. Also note that a high heating rate (1 – 2 min) may be a sign that the device uses plates as heaters; these laminators are considered less advanced than heated roller models and are less suitable for some special tasks (such as laminating photos). So, powerful professional devices will inevitably have a rather long warm-up time — up to 30 minutes in some models.

— Reverse. Possibility of rotation of a roller in the reverse direction. This function will be useful, foremost, in emergency situations — bending or jamming of the document, getting a foreign object under the rollers, winding the media on them, etc. The timely inclusion of the reverse not only allows you to do without laborious repair work with the disassembly of the unit, but in many cases it saves the processed material from damage.

— Unjam lever. The possibility to unclench the laminator rollers (strictly speaking, increase the distance between them). Along with the above described reverse feature, it is an "emergency" function, designed primarily to remove a jammed or skewed document, a foreign object, etc.

— Temperature adjust. Possibility to adjust the heating temperature during heated lamination (see "Type of lamination"). This function allows you to optimally adjust the operating mode to the specs of a particular film and media.

— Foiling. Possibility of using a laminator for foil coating. Some of these models are even capable of embossing, usually in the form of an ornament, which is indispensable in the making of postcards, business cards and other similar products.

— Photo lamination. The ability to use a device for laminating photos. It is believed...that only laminators with heated rollers are suitable for such work, because models with separate heating plates do not provide sufficient heating uniformity, which can damage delicate materials such as photos. At the same time, it is worth noting that in this case we are talking only about pictures printed on photo paper; for a plain paper (even with a printed photo), any laminator is suitable.

— Sheet autofeed. The system providing automatic feed of the documents to be laminated. The ability to load a whole stack of sheets into the laminator instead of feeding each of them separately is important primarily for large volumes of work; in addition, autofeed affects the cost of the device. Therefore, this function is found mainly in high-end roll models (see "Product Type").

— Rewinder. Rewinder is an additional shaft installed at the outer part of the laminator. It can be used, particularly, for winding the backing paper in cold lamination (see "Type of lamination"), as well as for winding laminated media during the heated processing. Anyway, the rewinder can be very useful when working with long media — it is often more convenient to wind such material on the outer shaft immediately after coming out of the laminator than to look for another place for it.

The electrical power consumed by the laminator in usual operation. Even in A2 format models (see above), this figure rarely exceeds 2 kW (which is comparable to the consumption of an electric kettle or iron), not to mention simpler devices. Therefore, in most cases, this spec is a reference and practically may be used only in rare cases. But when choosing a professional large-format laminator with media size of A0 or A1, you should pay special attention to power consumption — it can be up to 10 – 11 kW, which puts forward specific connection requirements.
