Product Spotlight - Shrink Bands


Shrink bands are made from thin pieces of plastic that have a significant impact on the finished look for your products. Shrink bands are commonly used by numerous industries as one of the best and most easily identifiable methods of tamper evidence.

PVC For Shrink Bands

Shrink bands are typically composed of PVC for various reasons:
  • PVC retains grease, oil, acid and oxygen barriers even at the thickness of .2 mm.
  • PVC is crystal clear and can easily be colored and printed.
  • With a high melting point, PVC can be applied with a heat gun without losing integrity and will maintain the shape needed to create tamper evident seals once cooled.

Shrink bands provide tamper evident seals to plastic and glass bottles, jars, vials, and metal tins. The vertical perforation provides an easy guide for removing shrink bands from containers. Shrink bands help reassure customers that the products they purchase have not been opened or tampered with after production. Shrink bands are versatile, cost-effective and can easily integrate into many types of production processes.

Shrink Band Options

Shrink Band Options
Clear PVC shrink bands are sold in widths of 25 mm up to 165 mm and are compatible with sealing small vials up to larger jars. Clear shrink bands will not interfere with the appealing packaging choices you have made and there is no added bulk to shipping. SKS also has an option to add printed text such as "Sealed for Your Protection" to your clear shrink bands to draw the customers attention toward your commitment to product protection.

Colored shrink bands are available in black shiny or matte, red, white, gold, green and yellow. Colored shrink bands can bring a touch of color and variety to your packaging. Sell salad dressings? Choose red shrink bands for red pepper infused flavors and green shrink bands for herb blends. Colored shrink bands can be used to aesthetically enhance your containers. Choose black shiny or matte shrink bands to bring out the boldness of your label or white shrink bands to provide a clean, sleek look.

Shrink Band OptionsClear and colored shrink bands have a quick application process; just a short amount of time with a heat gun and you have functional tamper evident seals. SKS offers the EC 100K heat gun, available with nozzle attachments that can be used for a large range of containers and a hard carrying case for easy transportation.

Choosing a heat gun over a basic hair dryer is recommended. While a household hair dryer will work applying shrink bands, a heat gun will be more efficient for fast and consistent production runs of any size. Our heat gun will have two settings with heat levels of 500° F and 1000° F and an option for high or low fan speed. A quick "how-to" video guide on shrinks band application is available on our website.

SKS also offers an added service for Customizable shrink sleeves to bring forth the next level in tamper evidence and design.

Additional options include metallic and sparkling non-metal inks, coatings, and specialized perforations.

Customized shrink sleeves can provide your product with a standout appearance without the added cost of customized containers and caps. The minimum quantity for an order of customized shrink sleeves is 50,000 pieces. To start a quote contact our helpful customer service department for additional information.

What if shrink bands are not listed?

The fastest way to purchase shrink bands is to locate the containers you would like to use and click on the shrink band image within the Add-ons section for a drop down menu of available options. We also have a shrink band compatibility chart for size reference and container options.

Here are a few reasons why shrink bands may not appear in the Add-ons section with the container(s) you have chosen:

If shrink bands are not listed for your product of choice, but you have calculated the size that could work with your container, feel free to contact us to create a customized shrink band to test for your product. SKS will provide a sample of the shrink band sizes you have selected to test before purchasing full bags or cases. Samples are one of the ways we like to ensure quality service while purchasing your packaging needs.
  • The shrink bands will not work properly with the specific containers.
    In some situations, containers will have measurements that seem compatible with shrink bands listed, but the shape, neck or shoulders of the containers can be unsuitable for shrinks to form a tamper evident seal once applied.
  • The caps paired with the containers are not compatible with shrink bands.
    Some of these caps can include lotion pumps, twist top caps and bulb glass droppers which are not compatible with the function of shrink bands.
  • The correct size is not available. Shrink bands must be within a certain number of millimeters of the diameter to work properly.
    Shrink bands that are too small will tear on the perforation before sealing, and shrink bands that are too big will not correctly shrink and will cause excess plastic around the neck of the containers.

For assistance in testing and fitting shrink bands to the containers you have located within our extensive inventory, be sure to contact our customer service department.
