Measuring Force

Learn what adhesion is, how it is measured, what a test really measures relative to the true adhesion between two surfaces, how adhesion affects the performance of the final laminated or multilayer product, an ideal adhesion test between two materials, and what the common T-peel adhesion test measure.

Mastering RFID

This article analyzes existing ESD control standards and interprets them for RFID label converting. In addition, available static control methods in RFID converting are examined along with a case study for static control on an RFID tag insertion module for a narrow-web press.

Mastering RFID, Part 2

This second of a two-part series covers development of an ESD protection program.

Fighting Flaws

A standard coating line requires different types of equipment to function effectively to produce a defect-free product. Often the main focus of defect reduction efforts is on the major equipment and on application conditions, dryer conditions, and the web transport system.

The Design Supply Chain

The packaging industry needs a comprehensive workflow that optimizes process efficiency throughout the entire supply chain.

Truth or Myth?

There are many proposed theories that might influence the slide angle. We tested extensively to determine if these postulations are true.

Detecting the Edge

Web guides have evolved dramatically since their first appearance on converting lines in the 1930s. Electronic edge detectors and electric motors gradually displaced pneumatics and hydraulics as demand grew for greater accuracy and reliability, and tolerance for leaky hydraulics diminished. The earliest electronic systems were far from perfect—in particular the edge detectors were sensitive to dust and temperature swings—but they were a big improvement over their predecessors

Taming Plastics

Plastics may be flexible, brittle, or stretchable; thin, medium, or thick; clear to opaque; really easy to tear, easy to tear, tough to tear, or impossible to tear; have excellent "memory" or have no "memory"; react readily to heat or don’t react to heat at all; allow air to pass through them or actually prevent bullets from passing through them. You get the picture. So how do you cut, crease, and perforate such incredibly diverse (and perverse) materials

Film Opens New Markets

Since pressure-sensitive labels and tapes—and other materials such as stamps—have become more sophisticated, the market for these materials has been expanding rapidly. In such product constructions, it has been common practice to apply a release coating, typically a silicone-based material, to the paper liner from which the materials are peeled or dispensed.

Die Options Explained

The wide range of specialty packaging items now being ordered by customers often makes optically registered die-cutting systems the better method for cost-effective and high quality die-cutting. However, new types of dies make it important to reacquaint yourself with your options when using an optically registered die-cutting system.

Web Tension 101

Typically, tension is measured in PLI (pounds per linear inch) in the US. If you know PLI and you want to know total tension applied to the web, multiply PLI times the width of the material in inches. If you know total pounds of tension applied to the web and you want to know PLI, divide the total pounds of tension across the web by the width of the web in inches.

Eliminate Pesky Bubbles

How do bubbles form, and how can we eliminate them? Avoid introducing air into the coating fluid.

Mechanics of Tension Control, Part II

For this basic tutorial in the mechanics of web tension control, tension is defined as the force applied to a continuous web of material in the machine direction.

Extrusion Dies

Due to the intense competition in today's marketplace, extrusion-coating converters face greater challenges than ever.

Lasers Beam

Digital converting is on the verge of widespread adoption in flexible packaging applications due to compact carbon dioxide lasers.

The Rx for RH

Remember the converting problems you had last winter? Reducing them this year might be easier than you think.

Weight Control

The quality and performance of a coated product depend on obtaining the desired coating weight and maintaining its uniformity in all the rolls of manufactured product.

Optimum Release

Successful use of film liners calls for selecting the right release coating.

A Secure Alternative

Micro-optic films have been developed to respond to the ever-diminshing security provided by holograms and DOVIDs.

CMYK=RGB - The Digital Color Revolution

Our printing industry is experiencing rapid changes. Yet the most obvious change that needs to be made has been overlooked for decades.

Mixing It Up

Analyze your mixing process to root out the cause of poor performance.

Just Rolling Along

Optimize production rates and control costs with a rolling ring linear driver system.

Pay Attention to Tension

Our web handling expert reveals the subtle secrets of the slitting/rewinding process.

What's Ahead for Industrial Ink Jet?

What are the best uses for ink jet in an industrial setting? An expert answers questions about the basics of ink jet technology.

Standardizing Anilox Rolls

Streamline your anilox roll inventory to increase your bottom-line profits.

Retrofitting Older Sheeters

A dual rotary knife retrofit on an older sheeter can improve equipment productivity and reduce waste effectively.

Winding Better Rolls

It's not obvious how winding adds value to your product (it does), but it is obvious when it's done poorly.

Model Behavior

Computer modeling is a relatively new tool converters can use to improve the quality and productivity of coating and drying operations.
