High-speed sleeving expertise

YPS are delighted to bring to market a first-class, sophisticated flighted bar shrink wrapping solution dedicated to high-speed applications, thanks to our partnership with a world-leading Italian manufacturer. This supplier dominates the high-speed sleeve wrapping market, staking a claim to some of the most advanced packaging lines found in factories across Europe, Asia and the Americas – and so it is with pride that we can extend their expert solutions to our UK customers.

Impressive speeds

The single-lane models in our range can run at speeds of up to 80 packs per minute but twin-lane variations can see speeds of up to 160 packs per minute achieved. Although ideal for a wide range of applications, this capacity for rapid speed lends these machines particularly well to food, beverage and bottling plants which require a high-volume, high-demand solution.

Sealing without jaws

Flighted bar sealers operate without the traditional sealing jaws found on most sleeve wrappers, meaning they are incredibly low maintenance. Sealing jaws typically require cleaning at regular intervals or after every lengthy production run so this is no longer a consideration with the flighted bar range. Furthermore, without the repeated cutting and sealing motion required from the jaw after each pack, our machines can afford to be significantly faster and a continuous flow in production is delivered.


Unlike other sleeve sealers, which utilise both a top and bottom roll of film that result in a central seal around packs, the flighted bar models use only one roll of film, mounted underneath the conveyor.  The film feeds upwards and comes up and over the packs as they travel forwards until a single full sleeve envelops them, which is then cut cleanly before being shrunk inside the shrink tunnel oven. This wrapping style normally leaves a ‘bullseye’ hole at each side of the pack, which can be beneficial for heavy packs of jars or bottles to assist with lifting.

At point 1 on the diagram below, the stream of loose packs enter the wrapping line on a 90º single-lane conveyor. This negates the need for a divider to lane the products, saving costs as well as space. The format also accepts a wide variety of pack sizes or container types, without requiring different belts. Changeovers between packs are therefore fast and easy without the need to regulate the guides on the different lanes.

A wheel of dividing bars group the packs with a continuous linear motion into the desired format and a twin belt system separates the collations into the production line using an electronic cam.

At point 2 the products are pushed from the single lane conveyor to the multi-lane conveyor. The unwinding of the film is controlled by brushless motors that ensure the precise and continuous adjustment of the film tensioning, controlled by a piston.

When the operating film reel from position 3 is over, a manual sealing bar joins the films. The film is cut with exact precision by a blade controlled by a direct-drive brushless motor, then wrapped around the group of product and overlapped on the bottom of the pack.

The packs enter the energy-efficient shrink tunnel at stage 4 for fast, smooth film shrinking.



ASW Operation

Low maintenance

As well as the absence of a sealing jaw to upkeep, these machines benefits from doors with rounded protection, allowing for more space inside the unit and externally mounted motors on the machine side edges which are easily accessible during routine maintenance. For any required manual intervention, operators do not need to enter the internal parts of the shrink wrapper at all.

Caters to any collation

Whatever your desired pack formation, our high-speed flight bar sealers can match it. Their sturdy pusher bars can be set to produce a wide array of collations including 3 x 1, 3 x 2, 3x 3 etc. Both singles and multipacks are a breeze with the flighted bar range, offering the flexibility you need for your whole product range.
