Meantime, Gardner Business Media announced today that it had reached agreement to purchase ECM's yearly injection molding conference business. Terms were not disclosed. Gardner, the parent company of Plastics Technology magazine, will assume official ownership of the annual Molding Conference beginning in 2015.

 

The Molding Conference was started 24 years ago by Amos Golovoy, a former engineer at Ford Motor Co, and has been owned and operated by ECM, Plymouth, Mich., ever since. Golovoy has agreed to continue his involvement in the conference.  

 

Golovoy describes the yearly Molding Conference as “a unique event organized by a volunteer committee of all branches of the industry, including molders, moldmakers, materials suppliers, and the trade press.”  The latter is a reference to Matthew Naitove, Plastics Technology’s executive editor, who has been part of the Molding Conference’s organizing committee for the last three years. Gardner plans to continue with this model for future events.

 

 “The Molding Conference has been nurtured by me and my team for nearly a quarter of a century,” Golovoy stated.  “Gardner Business Media and Plastics Technology Magazine supported the molding conference from its early beginning, and I am convinced that they have a strong commitment to make the Molding Conference the ‘must attend’ yearly event for injection molders worldwide, where they can learn about new technology and network with their peers. I welcome the opportunity to continue being involved in the conference. Gardner and its Plastics Technology brand are the natural home for the molding conferences.”

 

Founded in 1928 with the launch of Modern Machine Shop magazine, Gardner is a family-owned and operated media business whose eight brands all focus on manufacturing. “Gardner’s mission with all of its brands is to be recognized as the worldwide leader,” notes Rick Kline Jr., part of the company’s fourth-generation ownership group and publisher of Plastics Technology.  “We are committed in no uncertain terms to growing our business in plastics. The recent additions to our editorial staff have been made with that objective in mind. The purchase of the well-known and highly-respected Molding Conference is yet another demonstration of our commitment to this market.”

Lots of Expansion Brewing In Film Extrusion

By: James Callari 30. January 2014

 

There’s been a spate of expansion news in film extrusion, as processors are reporting new installations at breakneck speed.

 

Most recently, Next Generation Films, Lexington, Ohio, announced that it has ordered three blown film lines from Windmoeller & Hoelscher, Lincoln, R.I.,  to bolster its capacity for its core business and build up its presence in the barrier film market.

 

Next entered the barrier film market in mid-2012 and has ordered two Varex II lines, one 87-in., 7-layer line and one 103-in. , 9-layer line, to cultivate this segment of their business. Notes Dave Frecka, founder & CEO at Next,  “We want to solidify our position as a key player on the growing barrier market and are investing in the technology we need to do so.”

 

Varex II was introduced at the K 2013 in Düsseldorf as the successor to the well-known Varex line. W&H engineers spent roughly three years reviewing each component of the existing range, making both small and large changes to improve output, safety and efficiency.

 

 

The third line ordered, a 126-in. 5-layer Varex, will be installed this spring and used to support the company's core business.

 

Meantime, BJK Flexible Packaging, a specialty films producer based in Louisville, Ken., has expanded its film production capacity with the addition of a new five-layer blown film line from Reifenhauser Inc., Wichita. Kan. The company recently installed and commissioned the new line (see photo bottom) in an all-new 30,000 ft² addition that it built specifically for that purpose at its Louisville headquarters.

 

The new film line started running in November. It will be used to produce five-layer film structures that will provide a better alternative than 3-layer structures, according to Brian Krein, Chairman and CEO of BJK.  The 110-in. wide line is equipped with with a 550-mm die and is capable of running more than 1,500 lb/hour of material. “It’s our feeling that 3-layer’s future for many film segments will move to 5-layer,” Krein noted.  “5-layer films allow more flexibility in general to extrude for specific applications.” These sentiments are consistent with those expressed by ExxonMobil in meetings with Plastics Technology at last year’s K 2013 show.

 

Leading U.S. stretch film producer Sigma Stretch Film, meanwhile.  recently installed two stretch film lines from Gloucester Engineering, Gloucester, Mass. including a 5-layer cast stretch film line to the company’s facility in Shelbyville, Ken., and a 5-layer blown stretch film line (see photo above) in Belleville, Ontario.  The cast film line has been in production since October 2013 and the blown film line will be in production early this year. 

 

 

The 9-up cast stretch film line includes four Contracool extruders equipped with PIB injection that feed a Cloeren feed block and auto die.  Also included is a casting unit with temperature control unit (TCU) and a 1002-DS Surface-Center winder with dual overlapping single turrets.  The line is enhanced with resin vacuum loading, loss-in-weight blending, gauging, profile control and a trim reprocessing system all controlled by the Extrol 6032 control system.    

 

The five-layer blown stretch silage film line includes five Contracool extruders equipped with PIB injection feeding a low profile five-layer IBC die and air ring.  Also included are a bubble cage, Traversanip oscillating primary nip roll with composite roller collapsing frame, secondary nip roll, and a dual turret 1002-D Surface-Center winder.  The line is enhanced with resin vacuum loading, feed throat gravimetric blending, and a trim reprocessing system all controlled by the Extrol 6032 control system, and containerized controls.    

 

Here's A New Way to Produce Bags from Scrap

By: James Callari 29. January 2014

Macro Engineering and Technology Inc. has developed and patented a new method to produce trash bags and similar film products from post-consumer material.

 

Nowadays, when producing bags containing high amounts of reclaim, most processors “bury” the scrap in the core layer of a multi-layer structure, and sandwich it with skin layers made primarily of virgin material. The problem with that method is that impurities originating from the scrap layer—such as gels and pins holes—tend to migrate or “leak” through all the layers of the structure, explains Mirek Planeta, the former president of the machine builder who now heads up the firm’s R&D efforts. "In two- or three-layer coextrusion, when (the material exits) the die all of the layers are aligned, so any impurity will create a fault or defect in all the layers at the same time," Planeta explains.

 

Macro patented approach is to produce the bag from two separate films, which are blocked after they the exit die to prevent any gels or pin holes from aligning. This arrangement adds to the film strength because one film with the defect is essentially "covered" by the second film without the defect. The film is blocked so that the two layers act as one to prevent the gel or other defect from seeping through, Planeta notes.

 

This can be achieved by blocking a two-layer tube, or by extruding  using a dual-orifice die to create two bubbles, thereby producing two separate  films. It can be done with one or more extruders.

 

In trials at its plant in Mississauga, Ontario, Macro found film produced by this method showed an improvement in both tear strength and tensile strength. Macro trialed both blends of post-consumer scrap with virgin, as well as a structure in which both of the bubbles were made of 100% reclaimed consumer scrap structure (photo). Both cases showed no evidence or gel leakage or pin holes, Macro officials state.

 

The company's intention is to license the technology to interested processors.

 

Paper or Plastic?

By: James Callari 16. January 2014

Usually when people hear “plastic money” the first things that come to mind are the credit and debit cards they regularly use in lieu of paper currency. But the whole paper vs. plastics question seems to be taking on an altogether new meaning. An article that ran last year in The New York Times reported that after 300 years Britain will be converting from cotton-based paper to plastic beginning with 5 and 10 pound notes. According to the article, Canada and Australia and about two dozen other countries have already the switch.

 

The Bank of England is expected to contract with Innovia Films to produce the plastic currency, according to a press release on the processor's website. Innovia's product is a biaxially oriented polypropylene (BOPP) film it calls Guardian. Guardian is used as a substrate by more than 20 other countries, including Canada, Innovia says. The company plans on investing more than $30 million at its facility in Wigton, Cumbria to support the new business.

 

The U.S. is not expected to follow any time soon, but the article in The Grey Lady, as the Times is known, did extol the virtues of plastics in this particular application: it is more durable than paper and also harder to counterfeit.

 

Australia is credited with inventing plastic currency in 1988 from BOPP. Sources say Mobil Chemical developed a BOPP-based alternative to paper for the U.S. market years ago.  Though described as a “fantastic product,” it could not overcome government obstacles. Last October, New Delhi, India-based Jindal Poly Films, Ltd., announced it had completed its acquisition of ExxonMobil Chemical's global BOPP films business, a process that started in 2012.

 

Here's some background on England's move, which is scheduled to become effective in 2016.

 

Then check this out. It seems that when plastic became the substrate of choice in Australia, the process was downward blown film.
