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

在大多数情况下，标签是在涂层纸的支持网上提供的。本文需要良好的拉伸强度，可以将其拉入标签。尽管如此，任何损害，例如边缘略有痕迹或过度深层的损坏都会夺走其几乎所有的力量。

在处理标签卷或在标签机中处理时可能会发生划痕。随着标签通过各种指南和固定滚动器的滚动器的任何未对准滚筒的错位都会将网络移出所需的路径。一些操作员甚至机械师都会尝试使用卷卷上的指导项圈将网络迫使网络到所需的位置。这很少按预期工作。它通常沿着网缘拖动，导致划痕和弱点。

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.

粘合剂

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.

如果标签/容器组合工作正常，但开始引起问题，请检查供应商没有改变粘合剂。

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.

这些只是标签机问题中的一些，可以使您在生产线上发出坚果。我今天的要点是不要立即假设机器有故障并开始调整。在触摸任何东西之前，请弄清楚问题到底是什么。

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.

可以在连续卷中提供胶标签，也可以作为单独的Precut标签提供。当在卷上提供时，标签几乎总是是正方形的或矩形的。这使它们可以用直叶片切断。一些标签可以划出形状的标签，但这为机器增加了复杂性。另一个问题是，需要从标签中取出diecut的废料。即使在最佳操作下，这也永远不会是完美的。废物的积累会导致果酱或其他问题。

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。

也有一些弊端：

• 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

收缩套筒在包装方面有很多用途。它们可用于标记和识别诸如洗发水/护发素的诸如易碎玻璃容器之类的多包，并使Blah玻璃容器看起来像精美的陶瓷。它们也可以用来提供安全性或篡改密封的消息，这是它们最常见的用途。

大多数收缩套筒都是由PVC膜制成的，但有时会使用其他材料。它们通常是通过将扁平膜折成密封并焊接纵向接缝来制作的。由扁平膜形成可以访问用于打印的完整胶片。某些袖子材料被挤出为管子，但通常不打印。由于几乎所有胶片都已印刷，即使只是“保护您的保护”消息挤出的套筒材料也将在本文中忽略。无论如何，两种类型的胶片的应用都是相同的。

通常在连续的卷轴或卷中提供胶片以供机器应用。在某些应用中，使用了前袖。这些是手动应用的，不在本文的范围之内。

两种类型的打印通常与袖子一起使用：连续和注册。虽然电影相同，但注册胶片需要一台能够注册的应用机。
