Woven fabric is a packaging material stretched plastic tape. Woven fabric bags are insensitive to pressure, fracture and buckling. Even if they are moved by hook or damaged by nails, they break not occur and the valuable content is in the bag. In addition, woven fabric, in comparison to conventional films very thin, making it easy, but is still robust and durable - and with low raw material consumption. What is more, that it is completely recyclable.
The FMS technology (Form, Fill & Seal - Form, Fill & Seal) is a fully-automated, cost-effective packaging method for powder, granules, flakes and many other bulk goods. On the filling machine are made of plastic film tube endless bags that are immediately filled with the product and then sealed. The top of the filled bag and the bottom of the next bag to be welded simultaneously. The great advantage of the FFS method is that the bags are closed by welding. FFS machines do not need needles (which can easily break) or yarn (must be actual power again and again). As a result, no thread groups mingle with the medium, and the bags are hermetically sealed, because there are no stitch holes.
To date, it was not possible to use tissue from plastic strips on FFS-filling. Through joint Abstrengungen it is now the first woven fabric that was produced on machinery from Starlinger-Dow pellets to use for FFS-filling of Haver & Boecker. The so-called "woven * FFS" technology is specifically aimed at bottling plants in the chemical industry and building material and food industries.
The advantages of woven sacks * FFS include:
Robust but lightweight packaging material
Protection of the packaged goods from all around the sealed, waterproof packaging
Thanks to the fully automatic FFS machines from Haver & Boecker, the control activities are limited to roles and format changes.
Optimized bags: constant monitoring of the bulk density, and adjust the bag length.
Clean blind surfaces and greater safety during transport due to compact filled bags.
The lower consumption of raw materials helps to save resources and money.
In the development of "woven * FFS" Dow, Starlinger and Haver & Boecker claims to have paid particular attention to making the switch from PET to PE woven fabric for the bottlers as easy as possible. Customers who already have FFS systems of Haver & Boecker, should have to make any major conversions. To take advantage of woven fabric, a few minor changes to the FFS system was needed - and simply using a different material roll.
Even companies that have processed so far, due to customer and market requirements, tissue and could therefore not use FFS bottling plants, will now have the opportunity to take advantage of this fully automatic, cost-packaging concept. The high production capacity of the facilities and the time and cost savings in operation and maintenance would mean that the investment pay off in this new system in a short time.
The new packaging concept is presented for the first time at K 2010.
