Equipment also comes with materials-selection and processing know how.

Macro Engineering and Technology, Mississauga, Ont. has recently enhanced its Quadex bi-axially oriented multiple-bubble lines to produce films with nylon and EVOH, particularly for bone-in-meat high-barrier shrink bags. The machine builder reports that it has developed the process and the right combination of materials for extruding these films and will include this know-how with the line purchase.

This line offers the latest bi-ax process technology, computer-based automation, and overall control. Line features include:

• Different configurations for 7, 9 or 11 layers.

• Ability to run up to three layers of nylon layers with the main barrier layer being EVOH

• Film width from 8-20 in.

• Film thickness from 40 to 90 microns

• Production output from 110 to 330 lb.

Macro says it has more than 60 biax lines running worldwide. The newest Quadex line has just been successfully installed at a customer in South America.




  • Stretching Film's Limits

    In the hyper-competitive stretch-film market, more layers often mean more market share. Moving from five layers to seven or nine can give an edge through higher performance or reduced cost.

  • Stop Die Buildup

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

  • Why—and How—to Baseline Your Extruder

    If you don’t baseline your extruder, then how are you going to set realistic expectations for its performance? Here's how to get going.
