At NPE2018, PE film processor Sigma Plastics Group announced significant equipment investments along with an entry into an all-together new business.The film extrusion powerhouse said six new Optimex FFS lines it ordered from Windmoeller & Hoelscher (W&H) will be up and running at its Republic Bags plant by the end of the summer, producing blown film for form-fill-and-seal (FFS) sacks. This installation marks Sigma’s foray into the FFS market. The lines will produce about 45 million pounds of film annually, printed and gusseted.

Meanwhile, Sigma’s McNeeley Plastics plant has ordered two Varex II blown film lines—a 3-layer and a 5-layer system. The latter will be equipped with W&H’s Turboclean resin-purging and quick-changeover system, and a Filmatic S winder with reverse-wind capability. This investment will support McNeely’s expanding business in converter-grade films. And last week, Sigma started a five-layer Varex II line at its ISOFlex plant.

In related news, Sigma also announced it has ordered two high-output five-layer polyolefin-dedicated (POD) lines from Reifenhauser for its BJK plant, both equipped with the machine builder’s Ultra Cool IBC and Ultra Flat patented in-line flattening system. Sigma also said it bought another two lines from Reifenhauser for its Allied Extruders division: a three-layer high output system and a five-layer POD line. Both lines will also be equipped with Ultra Cool and Ultra Flat technology.

Sigma has also ordered new three- and five-layer lines from Hosokawa Alpine American, according to that machine builder. The three-layer line was recently commissioned, Alpine said.

  • Stop Die Buildup

    Die buildup, also called die drool, die bleed, or plate-out, can plague any extrusion process.

  • Don’t Wind Wrinkles Into Your Film

    Wrinkles are a major cause of defects in extrusion winding and converting, especially with thinner films, which are much more wrinkle-prone than thick ones. The cause of most wrinkles is located close to the roller where the wrinkle first appears and can be identified by looking at the orientation and pattern of the wrinkle. First, find the cause; then try to eliminate or at least reduce it.

  • Formulating LLDPE/LDPE Blends For Abuse–Resistant Blown Film

    A new study shows how the type and amount of LDPE in blends with LLDPE affect the processing and strength/toughness properties of blown film. Data are shown for both LDPE-rich and LLDPE-rich blends.
