shrink films: influenced by packaging trends, technology and increased demand, the shrink film industry has seen dramatic change in recent years.
A consumer tells how he transformed arizabit into a light fixture.
Another artist shared that she was drawing a picture of an Arizona bottle full of roses.
The third submitted its own photo, surrounded by 240 Arizona cans, 147 bottles, two kettles and a carton. [
What is the moral of these stories?
It has succeeded in making people enthusiastic about its packaging.
Perhaps one of the keys to creating this brand loyalty is that companies use shrink sleeve labels.
\"We used shrink labels for our Pina Colada label for the first time in 1995,\" said Michael Kutner, vice president of operations at the company (
Despite its name)
Located in Lake Success, New York.
\"It\'s very colorful and we need a label that reflects the art.
Starting with our first use of shrink sleeve labels, we have nothing but positive results in sales.
\"The use of shrink film is sweeping the beverage industry, but I won\'t stop there.
These films are now emerging in various markets ---
From the tamper-proof on the drug to the brightly colored graphics of the shrink label on Ragu sauce.
While shrink film is used in a variety of applications, shrink sleeves have become the darling of the industry.
\"This is the label for today,\" said Sharon Lober, President and CEO of Seal --It Inc.
Farmington in New York
\"The color is more vivid.
There are more properties around the bottle so you can print 360 [degrees].
Meet the requirements of the bottle.
It makes you look very delicate.
You can do a lot of things with contractions.
Although the sleeves have received a lot of attention, they are not the only use of shrink film.
Narrow network applications for shrink films can be divided into four categories: Shrink sleeves, wrap labels, tamper-proof tapes, and multi-shrinkpacks. Shrink sleeves.
Maybe the best.
Well known application of shrink film, shrink sleeve is admired for its potential of 360 [degrees]
Graphics, and the ability to shrink to the outline of an unusual shape bottle.
The type of film used for the production of shrink sleeves is called transverse (TD)or across-the-
Gary Gates, CEO of garron group in Monroe, North Carolina, said network orientation.
Three main base resins were used: PVC (PVC)
Modification of polyester and ethylene glycol (PETG)
Oriented polystyrene (OPS).
Some polyester (PET)
\"Also in use,\" he added . \".
These labels are also known as rolling, shrinking, different from the shrink sleeve.
Unlike the sleeves, the packaging label appears in the form of a roll.
The front edge and rear edge of the label are bonded with adhesive or welded together with solvent, and heatis is used to shrink the label. [
These labels are created using machines. direction (MD)orientedfilm.
The material is generally polypropylene and has limitations.
\"As you roll, you\'re lucky if you can get a 23% contraction.
You are looking for a very small number of contour applications, \"said Mary Ellen Reis, a VT Peacham certified packaging professional.
While the shrink film used to combine several items together is often a branch of the World Wide Web, narrow network converters can use shrink for smaller multiple itemspacks.
Shrink film can be used to pair items such as shampoo and conditioner, and a group of golf balls can also be added.
It is often used for promotional activities and the complexity of printing can vary greatly.
\"Sometimes it has up to 10 colors, sometimes it doesn\'t have any, it\'s only one or two,\" Lobel said . \".
The narrow network converter for this application works with PVC.
Tamper with the obvious band.
This is a very small market for our network converters.
\"Seamless shrink tubes are mainly used for tamperevident neck bands and other minimum print shrink bands,\" said gates sgates.
\"The printing on the pipe is flexo-version, mainly a color and random design.
The vast majority of tubing comes from Taiwan and mainland China because of low prices
The price is finally used in this country.
However, some converters are creating shrink sleeve labels including tamper-proof tapes.
Changes in the market are shrinking the film market is undergoing some changes.
Some are driven by packaging trends, while others are stimulated by changes in market attitudes.
A series of activities in the shrink film industry is a trend towards abnormally shaped containers.
\"Many consumer goods companies will produce proprietary bottles in very unusual shapes.
\"The only way you can label the bottle like this is to label the shrink sleeve,\" says Reis of packology . \".
However, in order to adapt to the trend of contour bottles, suppliers have been working hard to manufacture film materials with larger shrink of packaging labels.
Due to the limited percentage of shrinkage obtained from polypropylene, the packaging around the current label is limited to relatively cylindrical.
With the introduction of new materials with a higher percentage of shrinkage, this is changing.
\"With the packaging, the material used now is polypropylene.
It has very low shrinkage properties compared to the sleeves.
We are rolling out a high shrink packaging product, \"said Roger Brown, Industry Manager for shrink film labels for plastic suppliers in Columbus, Ohio.
The product is polystyrene-based.
Other companies are also working on film packaging labels with a higher percentage of shrinkage.
\"We are actively developing the machine\'s directional shrink film to shrink to 50%. \" the company of the broken Jia Layang, business manager, Professional Film, Eli Denison composite film is in paignsville.
\"The area we focus on has always been in the multi-olefin area because that\'s where we see the future.
\"Again, marketers are looking for other ways to differentiate products on shelves.
This sometimes means further product decoration.
For example, a conversion company is providing color changing ink to customers. Seal-
The company announced the launch of a hot color changing ink for shrink sleeve labels.
When affected by any kind of temperature, the ink will change color.
There are a variety of apps that can include promotional use, interactive games, or display perishable foods.
This will be a riseand-
Trend of shrinking sleeves?
\"I think so,\" Lobel said . \".
\"The dream of a market manager is to be able to do something new and different before someone else arrives. \" [
Other conversion companies have also responded to changes in the market.
For example, short-term demand in the century market has increased.
\"Manufacturers have been struggling to find high quality sleeves for their short-term needs, I. e.
Show, trade show and test market, \"said Greg Rogers, vice president of new business development for Bowling Green Century marketing.
In other efforts, the company focuses on customization, with shortrun sleeves as a niche.
\"We feel we have met very critical needs. An average-
For us, the size of each order is usually 500 to 3 thousand.
We\'re even working on programs that run in groups, running 50 or less per copy, \"said Michael Manahan, the company\'s manufacturing director.
When the sleeves are the same size, but the artwork or replica changes, a group run is performed.
In addition to the need for different trend drivers, environmental issues have also affected the shrink film industry.
PVC is the main resin used in American shrink sleeve material, but it has been opposed by environmental protection people.
\"Some people worry that if you burn PVC, you will discharge chlorine gas into the atmosphere.
In fact, most of the current incinerators have scammers to solve this problem.
But this does not reduce the views of environmental activists or the public.
In Asia, they don\'t use PVC because of this, \"said TimNicholson, senior director of business development at inelkgrove village, Fort IL Dearborn. [
Slightly] IllustrationsIs using PVC-
Is the real focus on material based or is it just perception?
\"There are many arguments in favor of PVC and against PVC on either side of these issues.
This is completely controversial, \"said Paul Wingate, sales manager at NC Bonset America inBrowns Summit.
The debate around PVC has led to the growth of alternate materials such as PETG and styrene (OPS & SBS)and PET.
In addition to easing public concerns about the environment, these films can bring other benefits.
The shrinkage percentage of PVC hovers around 60%.
Although it can be used in many containers, the bottle may require a higher shrinkage.
Generally speaking, the proportion of polyester fiber and some styrenecan is higher.
OPS has other advantages.
\"One thing to note is that ,[shrink]
The curve of OPS is a more gentle sloping curve, so it allows asmoother to transition to a container of abnormal shapes, \"Brown said.
While this is a couple of arguments to use PVCalternatives, some people think there are some shortcomings in these films.
PET is usually more expensive than PVC, for example.
Styrene may be unstable at room temperature.
Specifically, regarding SBS, \"There are a lot of natural shrinkage problems at room temperature, which makes it more volatile than PVC or PETG films.
You can\'t use the same ink system.
\"It\'s more sensitive to solvent attacks,\" Wingate said . \".
The challenge of shrink printing on shrink film presents some challenges that are not encountered when printing on paper.
First of all, the output of the label under pressure is not the appearance on the bottle.
This is because thelabel shrinks to the outline of the container.
Therefore, correct calculation of distortion is critical for a successful label.
This process can be laborious.
The converter will still print a 1/8 mesh pattern on the film, hold it, put it on the container, pass through the shrink tunnel, or hit it with a hot gun at high temperature to make it shrink.
Then they cut it off and measure it.
\"From there, the converter will go to a computer program and print the graphics.
This is not an accurate science.
\"You still have to top up the sleeves on the bottle, narrow it down and make sure the graphics are correct,\" Brown said . \".
The ink was also affected by the contraction of the film.
\"One challenge is to ensure that the ink is flexible enough so that when the material shrinks, it does not crack, break or cause dark stripes when the pigment shrinks,\" Gates said . \".
\"Most high quality ink companies have overcome the ink problem, but you can\'t just go out and buy one off-the-
The shelf ink you are using for pressure sensitive.
\"There may be another ink challenge when the converter uses water-based inks.
Traditionally, most of the work is done on gravurepres, but more and more companies offer flexo printing with water-based inks.
\"One of the problems we see on Bonset is the manufacture of shrink sleeves using water-based inks, and then the application of narrow network converters for these sleeves in a steam tunnel environment.
I saw some issues with re -.
\"The ink is wet,\" said Wingate.
Shrink films are also more temperamental than other substrates used for labeling, especially in thermal management.
\"There is a technology for printing films because [converting]
The device generates heat.
\"Even in the media, you need to make sure you don\'t narrow down the film,\" Brown commented . \".
\"In the shrink sleeve application, a percentage shrink in the film prevents the label from sliding through the bottle.
Temperature environment and thermal management of pressure equipment are very important.
\"While wrapping around the label and seam, in order to increase the percentage of shrinkage of the film used for labeling winding, the adhesive has been shown to be an obstacle.
\"The adhesive used to shrink the package is usually not enough to shrink more than 20%,\" Nicholson said . \".
\"Unless you have the adhesive to solve this problem, it is more important to shrink the material.
\"The problem with the larger shrinking area is that the adhesive does not shrink, but the film will shrink a lot.
\"Because of this, the film starts moving from where it was originally attached to the container and the adhesive is exposed,\" Rajan said . \".
This may be true if adhesive systems such as Hot Melt Adhesive are used, but progress is being made in this area, which may completely eliminate seams as a challenge.
The solvent system traditionally used to shrink the casing welds the label material together.
As different materials are introduced into the packaging market, the possibility of using a solvent system in packaging label applications is opened.
\"At present, people who use solvent systems
The Fed is using the wick app.
The label comes off the roll and is chopped for size.
Usually, in order to place the label on the container, two points will be placed on the container of hot melt adhesive or very high sticky cold glue. [
\"When the container and label rotate to a certain position, a felt wick comes in, dabs at the end of the label.
It will then go through the nip once, and the second part of the label will usually be pushed to the wet part, \"said Bruce maschold, president of Flexcraft Industries, Newark, New Jersey.
Although there is such an alternative adhesive method, it has a major limitation: the solvent system cannot be used with polypropylene.
\"Polypropylene can only be sealed with a hot pile, a hot melt or a bizarre UV curve, and you won\'t get the same effect,\" says Machleder . \".
Nevertheless, with the emergence of different materials such as OPS and olefin, the packaging of the label market remains an area of concern.
Technical improvements in the fields of film, adhesive and solvent systems will increase the growth of such narrow network applications.
However, it is better for converters interested in packaging labels to remember that this is the team\'s effort.
\"With the development of fed labeltechnology, no one entering this market will work in isolation.
\"You have to work closely with end users, machinery suppliers and film manufacturers,\" Rajan said . \".
All forms of shrinkage have the same advice.
There is great hope for shrinkcontinue.
In the past few years, shrinktechnology has improved in many ways. -
From the application speed of shrink sleeves to the increase of film production.
But as with any emerging industry, teamwork is critical to success.
\"The converter itself cannot do this.
They need help from ink suppliers, film suppliers and equipment suppliers.
First and foremost. It\'sdifferent.
\"Hopefully it will be profitable for them,\" Brown said . \".
