Charting a new course in film making

With a commitment to quality and an emphasis on consultative selling, four-year-old Charter Films is causing old-line competitors to sit up and take notice.

By Editor in Chief, Mark Spaulding -- Converting Magazine, 2/1/2003

"There's a better way to approach this marketplace than to simply offer tried and older technology, and basically just mimic what a lot of other companies have done or continue to do," says Charter Films vice president of sales and marketing Mark R. Tesmer. "I can with 100-percent confidence say that in the last four years, we've really tried to change the way customers look at film, and we've really tried to change the way they consider using film in their end-use products."

Tesmer is summing up what makes Charter Films different not only from its older, established competitors but also its equally young opponents in today's film-manufacturing segment of the converting field.

"There are a lot of exciting new resins out there that in our minds take things like EVA copolymers and others and make them not necessarily the best choice in certain packaging applications," he continues. "We've actually engaged customers to not buy film by the pound but to buy it by the 1,000-sq-ft instead. We're that confident in our ability here to try to sell into their world the way they understand it."

Charter Films is the brainchild of Tesmer, chief operating officer Chris J. Trapp and vice president David G. Timm. The three met after their separate careers with various film-making companies and packaging converters led them to all work at Atlantis Plastics. Significant consolidation in the film industry in the mid-1990s created the market conditions in which they felt they could be successful as an independent startup on their own. Trapp brought his mechanical engineering and production experience, Timm brought his broad technical and converting experience, and Tesmer added his sales acumen. Charter Films, a specialist in blown-film extrusion, was founded in late 1998.

"Let's see what happens"

"We knew we just had to have absolute, great quality as a startup company," Tesmer recalls. "From the sales side, I knew if we could keep lead times to a respectable two weeks or less, we could bring a good service angle to the marketplace, and then just see what happens."

What happened was Charter's rapid establishment, growing from eight original employees to today's total of 60, and from two initial film lines to five—the latest unit installed last summer.

Charter's manufacturing location seems an unlikely place to be making high-tech films. Housed in an 88-year-old former grocery warehouse in the far northern Wisconsin town of Superior, the operation is actually well placed. Charter serves predominantly Midwestern customers, although sales also extend to both coasts and into Canada and Mexico.

The four-story building is solidly constructed with 14-in. concrete floors. Holes were cut into each floor, and an extension added to the roof, for example, to enable installing one film line's 70-ft tower.

"Physically, you'd never build a structure like this to blow film in," Timm explains. "But it's actually ideally suited for blown film. We use all four floors to their fullest. From a cleanliness aspect, we've got one of the better plants because of the pure concrete floors.

"I think Superior has turned out to be an ideal location," he continues, in spite of its five-month-long winters. "We can joke about the climate, but I've made film down in Dallas, where it's very hot. When you're making film, half the battle is cooling it off."

Five words say it all

"Flat film and large rolls" pretty much describes Charter's product philosophy, Timm says. The company began focusing primarily on manufacturing multilayer coextrusions and sealant-layer films for flexible laminations. These materials, further converted by Charter customers, become printed rollstock, lidding or pre-made pouches. Industrial masking films for surface protection and high-density films for the tag and label market are now growing portions of the business.

"We had no intention when we wrote our business plan of wanting to make high-density films," says Tesmer. "Chris and Dave had lived the nightmare of trying to make high-density films on old, antiquated equipment. It's very difficult to make large rolls of good quality."

But old, antiquated equipment is not what Charter has; rather the operation boasts five state-of-the-art systems from Windmöller & Hölscher Corp. (Lincoln, RI). They include three 3-layer coextrusion lines—an 83-in. and two 63-in. units; and two monolayer lines—a 103-in. and a 63-in. unit. All are Varex® equipment with Optifil® P-2 automatic gauge-control subsystems and Filmatic® M multiple-mode or W dual-turret winders. Real-time online controls monitor and adjust gauge, cross-directional variation, yield and size control for width to keep them on target.

"We wanted to put in the best equipment that we could," says Timm. "We knew that if you have older equipment without some of the online controls, it's going to be hard to achieve quality. For example, we can run a 100-in. layflat, and have width control of +/-0.03 in. That's just not typical."

Keeping it new

Tour a typical film-manufacturing operation with multiple lines, and it's possible to see the age of the machines progress as you walk through. Even the details of the electronics—something most likely to age the fastest—can stand out. Not at Charter. Timm and Trapp have continually updated each machine. The four-year-old monolayer line, for instance, has already been upgraded five times.

"Every upgrade that comes down the path through W&H for this equipment, we've taken advantage of," Tesmer says.

Timm concurs. "Just because a line is five years old doesn't mean we want it to act that way."

Newness also extended to Charter's production staff as no experienced film operators were initially hired when the company began making product. With more than 15 years experience each, Trapp and Timm had seen their share of pluses and minuses in different work environments, and wanted to start with a clean slate. They didn't want workers falling back on bad habits learned at their former film-making jobs. "We wanted everybody to say this is the 'Charter way,'" Tesmer says. "We didn't want to have to untrain people."

"Charter is our way of taking a lot of the positives and leaving most of the negatives behind," Timm agrees.

As a filmmaker, Charter lives in the wide-web world and intends to stay there. All its downstream slitting and rewinding is done through contract converter Technipac (LeSueur, MN).

Changing the game

Helping customers figure out what sealant-film structure they really should be using rather than selling them what's already been created is the basis of Charter's consultative style of film making. It accomplishes this through an unusual film-selection guide that lets customers choose a sealant that works for most or all applications. Then the sealant is paired with one of six "backbones" for unsupported or supported structures, depending on the other properties the package may need, such as strength, toughness, clarity, stiffness or barrier. Via this method, 24 different custom coextrusions can be created for packaging ranging from horizontal form/fill/seal retort pouches to vertical form/fill/seal condiment packets.

"Most film companies create a new line of films, and then pitch them to customers," Timm says. "They'll tell their sales force, 'Okay, guys. Here they are. Go sell them.'"

"It's not typical in this business for a film guy to say to a converter, 'Why do you buy what you buy?'" adds Tesmer. "Our approach has been to understand why some of these older types of products are in place, and then really bring everything that Charter Films has to the customer to improve the process and improve the package."

Not all customers are ready for this new way of buying film. Many of Charter's opportunities, though, come about when a packager introduces a new product requiring different film properties or when packaging graphics change. Then, converters are also typically open to looking at new laminations as well.

"If you do nothing but sell 3% EVA laminations to polypropylene, you haven't done anything technically innovative or advanced the product in any way," says Timm. "So every time, when a re-bid comes up, guess what? It comes down to, "What's your price?'"

While remaining focused and not trying to be all things to all people, the company has done some "outside the box" projects. Among them: water-soluble films for the automotive industry, antimicrobial films and even a high-tech reinforcing membrane film for a NASA weather balloon.

Future directions

As Charter Films moves into its fifth year of business, company managers feel they've made significant progress in establishing the operation. With its commitment to quality and a drive to "change the nature of the film-making game," the future appears bright.

"We have a name now, a reputation," says Tesmer. "Certainly our bigger competitors know who we are."

Film Making 101: Web Handling

ISO Poly Films, deriving its name from ISO—the universally accepted standard for manufacturing excellence, is a certified ISO-9002 company, producing specialty films for the coating, laminating, printing and value-added converting markets.

The driving force behind the company, and the reason for its impressive growth, is quality. Its 50,000-sq-ft facility in Gray Court, SC, houses the latest in precision film-extrusion equipment, including three monolayer extrusion lines from Battenfeld Gloucester Engineering (Gloucester MA), two three-layer coextrusion lines from Windmöller & Hölscher (Lincoln, RI), and a third W&H coex line now under construction.

ISO's management and plant personnel strive to maximize production and quality while supporting growth and continuous improvement efforts. Jon McClure, founder, president, and CEO of ISO Poly, hired Tom Saxton to be vice president of manufacturing as the company was preparing to open in 1997. Saxton had directed an operation with 32 blown-film lines at his former employer, and his experience was critical in designing the ISO facility and in sourcing its equipment. (See Converting, June 2000, p.38).

Core shafts handle extreme conditions

Saxton anticipated heavy rolls and wanted core shafts to handle the weight of the rolls without being impossible for operators to handle. He turned to Double E Co. (West Bridgewater, MA), knowing from experience that Double E shafts were dependable and lightweight. Saxton recalled that the first shaft he ever bought from Double E more than 10 years ago replaced a steel shaft weighing 230 lbs. The Double E carbon-fiber replacement shaft weighed just 60 lbs and performed better than the original. Since then, Saxton has been a Double E proponent.

With rolls at ISO Poly Films ranging from 30 to 42 in. in dia. and weighing up to 4,800 lbs on machines running 250 fpm, even standard carbon-fiber shafts weren't stiff enough. Double E recommended and subsequently manufactured extra-high modulus shafts, which have been in service and performing well ever since. When specifying equipment for ISO's latest coextrusion line, Saxton insisted on Double E shafts because he didn't want to compromise the machine's ability for optimum performance. "You wouldn't put a Volkswagen Beetle engine in a Ferrari," he says.

Rollers eliminate web scratching

More recently, ISO Poly Films had problems with dragging and web scratching, especially when running high-clarity films and films with high EVA content. Because these webs are soft and easily marked, the traditional slats on the blown-film tower's A-frame were causing damage as the web passed over them. Saxton researched various options to correct the problem before deciding to replace the slats with Double E Light-Speed® carbon-fiber rollers. With the new rollers, Saxton says there is a "night and day difference" in the process. "The other alternative we considered involved retrofitting the entire A-frame with an air bearing system," Saxton explains. "We achieved the same results with a much smaller investment."

Since installing the Double E rollers, Saxton reports running many jobs that his company would have turned down before. "Customers are raving about the film quality, and they have already given us repeat business," he says. Saxton comments that the investment is having an immediate payback.

With quality as its corporate mantra, ISO Poly Films insists on suppliers that deliver the same quality they expect from themselves. Double E, also an ISO-certified manufacturer, provides consistent product quality, and "no surprises" according to Saxton. "I always know what I'm going to get," he says. —Edited by Mark Spaulding

Film Making 102: Corona treating

The Dow Polyolefins and Elastomers (PO&E) Technical Service and Development Group recently invested heavily in its laboratory capabilities via a new extrusion coating and lamination line. Located at the group's R&D headquarters in Freeport, TX, this multi-million dollar line, supplied by Black Clawson Converting Machinery LLC (Fulton, NY), enables Dow engineers to develop and evaluate new resin technologies, as well as provide fast resolution of day-to-day technical issues for customers.

The Black Clawson line begins with two dual-direction unwind stands, each capable of handling rolls up to 3,000 lbs and 60 in. dia. An auxiliary unwind for lamination accommodates 1,200-lb rolls up to 40 in. dia. Coating and laminating widths of 15-30 in. are possible, and a turret rewinder provides finished rolls up to 40 in. dia. Dual-range sensors throughout the entire line provide tension control for anything from thin films to heavy paperboard.

Creating tomorrow's substrates

Extrusion coatings and laminations play a significant role in today's package designs. Variables such as hot-tack and heat-seal strength, seal integrity, resistance to aggressive products, the ability to seal through contaminations, adhesion and cost can make an enormous difference when selecting a resin for packaging needs. Dow's new line has been designed to help package makers better understand these variables and their effects on package designs.

The line is also used for new material development and to support ongoing advances in extrusion-coating technology. Specifically, Dow's engineering team investigates the performance of new resins, chemistries, multiple substrates, and melt draw-down characteristics.

Getting real-world results

According to Dow project manager Jim Cooper, it's important that Dow is able to accurately replicate real-world processing conditions. Because it incorporates the latest extrusion-coating technology, the line generates performance data and samples that converters can use to develop new structures. All Dow extrusion-coating polymers are supported by the new line, including DOWLEX linear low-density polyethylene, AFFINITY polyolefin plastomers, PRIMACOR copolymers, DOW low-density polyethylene, Saran barrier resins and new INSPIRE performance polymers.

The versatility of the new coextrusion coating line is further enhanced by two Universal roll corona-treating systems from Enercon Industries Corp. (Menomonee Falls, WI). The 30-in. stations use ceramic-electrode technology and are engineered to treat any web material, including paper, film, and conductive foil/metallized film.

Cooper says selecting Enercon was an easy choice. "Over the last 10 years, our Enercon treaters have had outstanding reliability; in fact, they've never been down," Cooper says.

The first treating system improves the quality of the extrusion by pre-treating the web prior to the extrusion process. The second unit performs post-treatment, enabling converters to use the substrates for further value-added processes such as printing, embossing or hot-stamping.

The coextrusion line also includes a three-layer FG™ feedblock and EBR™ edge-bead reduction die from Cloeren, Inc. (Orange, TX), for enhanced flexibility. Cooper says, "The line's flexibility enables Dow to not only develop new resins, but is a key factor in the company's customer support operations. If a customer encounters a substrate problem, we can replicate their scenario on our line, evaluate it, and develop a solution for their requirements." —Edited by Mark Spaulding

Film Making 103: Gusseted bag forming & sealing

Polyplastic Products uses a CMD Model BSS 63-in. slit sealer in the formation and sealing of its gusseted polybags. With 14 extrusion lines in its plant, it didn't make sense financially for Polyplastic to install fixed slit-seal post gussets on each line. Instead, it went with a self-contained unit from CMD that can be shifted from line to line, as needed. "I purchased it right off the floor at the NPE show in Chicago," says Stephen Redlich, president and CEO of Polyplastic Products. Because Polyplastic is a custom bagmaker, it needed the ability to move the slit sealer from line to line. "On any given day our plant is always doing something different," says Redlich. But that wasn't the only reason for the purchase. The fact that it could slit-seal a tube into two or three webs at a time was a huge seller.

Before the slit sealer was installed, Poly-plastic was unable to make small bags in a two- or three-up application on shorter runs. "This enables us to wheel something in on shorter runs, reduce the timing on the setup, which reduces scrap," says Redlich.

Features on the BSS slit sealer include a thermal couple heat-range feedback system, which guarantees consistent temperature control, an advanced PID temperature control, web spreader bars, pneumatically actuated slitter engagement, and low-inertia aluminum idler rolls.

The high-output slit-sealer module is capable of reaching high temperatures for fast line-speed sealing applications. With its curved-plate web-tensioning system, it prevents loose or baggy edges and properly tensions the film through the critical sealing stage. "We find that the slit sealer allows us to run at high speeds and still have a good, strong seal. I don't think we've ever had any manufacturing problems or problems in the field with any complaint regarding the seal integrity from this machine," Redlich says. —By Laura Butalla
