It is hard to think of a product without at least one label. Labels have many purposes and come in many materials including paper, plastic and foil. They may be die cut in complex shapes or may be butt cut squares or rectangles. They may be sheet, roll or web fed. They may be applied with hot or cold glue or with pre-applied pressure sensitive adhesive.

品种似乎无尽。This paper will focus on automated pressure sensitive (PS) labeling equipment.

Pressure sensitive labels are supplied on a backing web. The web is coated with a releasing finish and the labels are coated with an adhesive. They are typically supplied on rolls though fan-folded labels are also used occasionally. Typically, even if square or rectangular, they are diecut on the web with a 1/16” gap left between labels.

操作压力的基本原理一世s easy to understand. The web is pulled across a peeler plate which bends it about 180 degrees. As the web is pulled backwards, the label continues forward, releasing from the web and either going directly onto the product or staging onto an intermediate applicator which applies the label to the product.


When problems occur with a labeling machine, some of us have a tendency to blame the machine and start adjusting. True, there are often machine based issues. They get out of adjustment, wear or even break. But the materials can cause a lot of issues too. This month I want to talk about some common problems that can occur with pressure sensitive labeling equipment.

Web breakage



Another cause of web breakage is improper die cutting. At the converter a knife must cut completely through the label without cutting into the web. If it cuts too deeply, into the web, it will cause a weak spot. The depth of cut may be checked with a felt tip marker. Place a section of web with not labels on a sheet of white paper. Rub the marker over the suspect areas. If it is cut, the ink will bleed through to the paper below.


Label adhesives It must be carefully matched to the product. There are several hundred types available and one sizes does not fit all. An adhesive that is fine for room temperature glass may not adhere at all to a plastic bottle at 40 degrees.


Changes to the container can cause similar issues. In one instance a label had been running well for more than a year when it suddenly started wrinkling on application. After considerable head-scratching it turned out that the converter had changed from flame treatment of the bottles to plasma treatment. This prevented the adhesive from achieving proper initial tack.

Excessive adhesive and/or rolls that are too tightly wound can cause the adhesive to squeeze out from under the label. When this happens the label face can stick to the back of the web, the web itself can stick together, glue can accumulate in the labeler rollers or all of the above. If the labels have the right amount of adhesive but are too tightly wound, all of the above can occur plus there may not be enough adhesive left on the label to properly adhere to the container.


Pressure sensitive labels are supplied in rolls, on plastic or paper backing strips with the adhesive already applied. Pressure sensitive label applicators are simple to operate and maintain, can run at fairly high speeds (up to 750ppm or more) and do not require cleaning of excess adhesive.

The downside of pressure sensitive labeling equipment is that on the fly roll splicing is difficult and the labeling equipment need to be shut down frequently, as often as every 30 minutes in some cases for roll replacement. Another issue is that the backing web needs to be disposed of. The backing web adds cost to pressure sensitive labels.

Glue labeling equipment apply cold glue or hot melt glue to the label or the package, most often a bottle or can, at the point of label application. Then they put the label on the package.


Another option is to use labels that are cut at the converter and supplied in stacks. Precut labels are often square or rectangular. For cans, they are almost always rectangular. Precut labels can also be diecut into virtually any shape by the converter.

As with anything else in packaging, there are advantages and disadvantages to both precut and roll fed labeling.


I’ve spent a lot of time watching labeler machine changeovers. One time sink I’ve noticed typically occurs after the changeover is complete. Or at least after the mechanic thinks it is complete. They are all ready to go and someone, often quality, says “Hey, Wait a minute. That label is out of position. It is too high.” Or too low. Or skewed, or off center or something else.

So they lose time re-adjusting the label position. Worse, they may lose even more time discussing, sometimes vigorously, whether the label is REALLY out of position. It’s an argument the mechanic can never win, But they still lose the time trying. In the end, they readjust

An issue with label position is that some plants have no good specification where it goes. Even where the specification exists, there may be no good way of verifying compliance. At one of my clients the maintenance manager got tired of this constant battle.

He came up with a simple idea. So simple that I had never seen it anywhere else. Actually so simple that it made me feel bad for not having thought of it. (The man was a genius). He was also a good machinist. He went to his shop, chucked a piece of plastic rod in the lathe and bored it out so the labeled bottle would drop in. He then milled a window in the side so the label could be seen.

Anyone can see at a glance whether the label is in position or not. No more disagreement. The mechanic knows, when setting the labeling machine, that the label is correct. If not, they adjust it. Everyone else can see that the label is in position so no more discussion.

The line restarts and everybody wins. This is an example of the Japanese concept called Poka-Yoke. Loosely translated, Poka-Yoke means mistake proofing. It means designing a process or part so that it is impossible to do improperly. This book, from Productivity Press, is filled with great, simple examples of mistake proofing.


Pressure sensitive labels, sometimes called self-adhesive, auto-adhesive or just PS labels, come with the adhesive (glue) pre-applied. In order to prevent the labels from sticking to each other and to allow feeding, they are supplied on a coated paper or plastic backing sheet. A pressure-sensitive labeling machine does have some nice advantages.

There are a number of advantages to PS labels:

  • Applicating machinery is relatively simple compared to hot and cold glue labels.
  • 标签几乎可以由任何材料制成
  • Labels can be die cut to any shape, embossed, provided with windows and other features to add function and pizazz to the product.
  • 传单标签,可以使用单个标签中的多个折叠页面组合
  • 速度的范围从手动操作中的几个CPM到高速线路上的500或更多CPM。
  • There is no adhesive mess to clean up.
  • There is no additional adhesive to buy.
  • 标签混音与切割标签的可能性要少得多。


  • Labels are more expensive
  • 滚动更换需要常规停止
  • The backing web makes the labels effectively twice as thick reducing the number that can be carried on a roll. This increases the replenishment frequency.
  • Splicing a new label roll to the runout roll is difficult to automate requiring stopping the labeler for splicing a new roll.
  • 支持网络材料是必须处置的废物
