Normal align=left> In recent years, with the rapid development of economy, stretch wrapping film has been widely used as a packaging material with excellent performance, and the market demand has rapidly increased. In line with this, the production of single-stretched stretch film requires more and more single-unit production, and the speed and width of the new production line are both higher and wider. As a typical casting process, the stretch film production line on the market currently has the following characteristics and weaknesses:

Normal align=left> 1. Using a shaft type winding

Normal align=left> 2. When the production line is wider than value="2.5" UnitName="m" w:st="on">value="2.5" UnitName="m" w:st="on"> 2.5 m , Cannot be compatible with 2 -inch or 3 -inch shaft winding

Normal align=left> 3. Further development of line width and speed is limited by critical speed

Normal align=left> 4. The minimum cycle time required for reel change is not conducive to the production of small film rolls.

Normal align=left> 5. In order to increase stand-alone production and production efficiency, Mr. Chang often produces large-diameter parent rolls, and then uses downstream multiple slitting and rewinding machines to produce small rolls that meet market requirements. Downstream slitter / rewinder has a large investment, low efficiency, and requires a lot of labor

normal align = left> SML Lenzing, Austria Machinery Co. stretch film in order to meet the growing international market demand, from 2005, to develop a new generation of stretch film production line and a special winder Winder 3000, which breaks through the traditional process The limitation overcomes the weaknesses of the above-mentioned equipment and achieves an unprecedented perfect combination of high speed and large width, and the newly-developed complete production line has been successfully put into operation on multiple users' sites.
