Microline solutions for tissue sector guarantee high performance thanks to top quality machines manufactured to the highest technological standards of this sector and with first-rate materials and components.

Microline manufactures shrink wrappers, case packers, bundlers, flow wrappers and palletisers for folded products (napkins, paper tissues, interfolded) and paper rolls (industrial paper rolls and AFH paper products). Today Microline is the only international company able to offer such a vast range of machines for the whole tissue industry: case packers for folded products and paper rolls, shrink-wrappers for paper rolls, conventional two-reel bundlers, or the latest generation flow-wrap machines.

Among the products making up the vast range of Microline packaging systems, case packers (for rolls and folded products) occupy a prominent place; these completely automatic machines are designed to form and fill “American-style” slotted cases, i.e. erected and glued cases, also in a display version. These machines are divided into two different types: horizontal (side-loading) case packers (ROM) and vertical (top-loading) case packers (RVM).

Basically, the machine picks up a pre-glued carton blank for an “American-style” slotted case from the case magazine, erects the case (with positive flap folding), fills it (according to the chosen collation) and closes the case with adhesive tape or hot-melt glue. The case packer also features a 1-metre capacity magazine that allows high autonomy; the case magazine can be topped up/loaded without having to halt the production cycle. Furthermore, if the machine has to manage different cases, “size change parts” (parts to be replaced in the machine filling unit) are supplied. Changeover operations are quick (max. 10/15 min.) and simple. Secondly, but no less important, there are shrink-wrappers for paper rolls, conventional two-reel bundlers, and flow-wrap machines of the latest generation.

The Microline roll wrapper (AL80) is a machine designed for horizontal packaging and wraps products with plastic film, either polyolefin (POF) or polyethylene (LDPE or MDPE). It is an automatic machine able to handle rolls in single, double, or triple collations; the output rate is up to 210 rolls per minute for the collation 1×3. The machine creates perfectly sealed bags containing the desired product collations. The bags are then heat shrunk to perfectly fit the shape of the product inside. This type of packaging is especially well-suited to paper rolls for industrial use (AFH) and hospital paper rolls.

Rolls are picked up from a conveyor belt, put “in phase” and then the wrapping cycle begins. If needed, a divider can be supplied to arrange rolls in parallel lines (double or triple collations). The pack is closed on its upper part by film edge overlapping, followed by ionisation and a longitudinal seal operation (without contact). Then it is transferred to the transversal seal station where the packs are parted.

The completely wrapped roll is made to pass through the shrinking tunnel. Roll packs can be customised with (glueless) label insertion or printed film. With this packaging process, film consumption is approximately 20-25% lower compared with other wrappers available on the market. The wrapping process does not generate any scraps or rejects of wrapping material, which cuts disposal costs and reduces shrinking temperatures. Given these multiple advantages, the cost of the entire process is 30-35% lower.

A new feature this year is no doubt the centre folding unit which can be integrated with the AL80 wrapping machine and enables the use of a centrefolded reel or a single-ply sheet reel. This device is capable of centre-folding a single-ply sheet reel and turning it into a centre-folded (or “V”) reel.

The conventional two-reel bundler (ML1500), on the other hand, is a machine suitable for packaging collated products. As a packaging material it uses heatsealable, heat-shrinkable polyethylene film (LDPE). The shrink-wrapped bundle remains partially open at the sides and a sealed pack can be obtained by using extra film. This type of packaging is especially
