Nordmeccanica Demonstrates Solvent-Free Adhesive Laminating

Nordmeccanica's open house this week in Hauppauge, Long Island, NY, allowed me to witness the lamination of 5 micron (0.00020") aluminum foil to oriented polyester film via solventless lamination.

Spring 2015 Travels: Nordmeccanica (Long Island), Malaysia (Part 3)

Another interesting Spring in terms of travels.  I'll cover the future first so that you have time to plan for the event should you want to visit Nordmeccanica in Hauppauge, New York on June 2, 2015.  Then more Malaysian tales.

NPE 2015 Wrap-up

Largest ever NPE show—More than 65,000 attendees from around the globe, more than 1.1 million sq ft (102, 250 sq m) of floor space occupied by more than 2,300+ exhibitors.

Reducing Surface Contamination

Most extrusion operations aren't affected by or concerned with surface contamination.  Those that are, such as polyester film and sheet manufacturers for critical end-use applications, face a constant battle to ensure a quality finished product.

The Benefits of Ozone in Extrusion Laminating

As I visit clients and conduct plant tours and technology assessments, one glaring omission that I quite often see is lack of ozone pre-treatment equipment.

ICE USA 2015 - Orlando, Florida Summary

Small, but full of content... that's how I'd describe the International Converting Exhibition (ICE) in Orlando, Florida last week.

What accounts for why Asian costs compared to US & Europe are so much less for extruded plastic film, sheet, profiles, and injection molded parts?

Malaysian Plastics Industry Update: January 2015

The Malaysian plastics industry is booming with varied technological levels employing a mix of legacy and newer equipment.


I just returned from PACK EXPO 2014 at McCormick Place in Chicago. This year, PACK EXPO combined with Pharma Expo to create one BIG show.  What a great show it was!!!

Microphazer Films Offers Unique Ultra-Thin Film Products

I recently had a chance to meet with Eric Arrington, founder and president of Microphazer Films out of Rochester, New York.  Arrington, a former scientist at Kodak holds multiple patents and has been in the extrusion industry for more than 30 years, and has invented a way to produce ultra-thin, un-oriented, amorphous polymer films.  I will review my interview with him in this blog.

Processing Tips to Prevent Gauge Bands - Part 4

This article will discuss in general terms what can be done with resin additives and formulations to improve resistance to polymer degradation and gauge bands.

Processing Tips to Prevent Gauge Bands - Part 3

Part 3 of this mini series will discuss proper shutdown procedures to minimize or eliminate gauge bands in extrusion coated and cast film products.

Processing Tips to Prevent Gauge Bands - Part 2

Strategies to eliminate gauge bands in extrusion coating and cast film by using proper operating procedures.

Processing Tips to Prevent Gauge Bands - Part 1

Since I starting in this industry back in the dark ages, before computers and GUI/HMI process control systems, universal corona treating systems, plasma treatment and the like, gauge bands have been the bane of the extrusion coating converter, and to a lesser extent, cast and blown film producers.  Nothing has changed in this regard.

SAM NA Open House

Hot off the press...SAM NA holds open house at it Phoenix, NY headquarters and Pilot Plant facilities.

Follow-up Post on a Workable 4-shift Schedule

There has been a lot of feedback on the blog posting made in September 2012, so I thought I would follow-up with a few more details. 

Plastics are Alive and Well in Southeast Asia

I had the opportunity to do some extrusion training recently in Southeast Asia, and all I can say is that plastics are alive and well there.
