Shrink Sleeves

Shrink Sleeves are one of the fastest growing segments in the label industry. As companies continue to re-design their packaging and the demand for sharper, more aesthetically pleasing designs continue to rise, more companies are converting their traditional pressure sensitive labels into shrink sleeve labels. Shrink sleeves offer companies more flexibility in terms of design and makes the products stand out from the rest of the competition.

What are PVC and PETG?

• Polyvinyl chloride (PVC) and Polyethylene Terephthalate Glycol-modified (PETG) are two commonly used shrink sleeve materials.
• PVC – Easiest to control, generally the most cost effective and offers good scuff resistance. Unit cost is less and it works better on some applications than PETG. There are two types of PVC – high shrink PVC and standard PVC.
• PETG – Offers the best scuff resistance, has highest percentage of shrink ability and easily recyclable. It’s also more stable and readily available. More customers are choosing PETG over PVC because it’s more readily available.
• PLA – Polylactide, or Polylactic acid (a misnomer since PLA is not an acid), (PLA) is a biodegradable thermoplastic made from renewable resources. The fact that PLA is biodegradable has increased its popularity in recent years and in addition to its use as printed shrink sleeve labels, PLA has also been used as a loose-fill flexible packaging material
• EPS Foam – Expanded Polystyrene (EPS) is a recycle-able thermal plastic material. Though a light material, EPS is relatively strong mechanically for its lightness and has a high resistance to heat, making it an excellent insulator. EPS offers exceptional form fit product protection.

SHRINK SLEEVE APPLICATION PROCESS

Manual – In this process, custom printed shrink sleeve labels are manually applied to containers before shrinking. This method is ideal for short runs and sampling prototype programs.

Automatic – Through an automatic application process, conveyors and other assorted machines are used to slip the shrink film material over the containers and then process them through the heat-shrink area for the form-fit that shrink sleeves create.

SLEEVE TYPE

Clear – A translucent sleeve which can be printed on but will otherwise show through to the container, and if a clear container, the contents therein. This type of shrink sleeve is ideal if you would like to showcase your product.

White – The shrink sleeve applied to the container is a white opaque film. Still printable, this type of sleeve will give the impression that the area of the container where applied is white.

PEFORATIONS FOR SHRINK SLEEVES

None – There will be no perforations on your shrink sleeve, it will be a solid label for the type of label selected.

Vertical – There will be vertical perforations that will make it easy to tear the shrink sleeve apart. This perforation is commonly found on safety-seals, and can be used in conjunction with horizontal perforations to create an entirely removable tamper-evident band.

Horizontal – This type of perforation allows part of the shrink sleeve, such as a tamper-evident band, to be easily removed without damaging the rest of the label so your product identity stays in tact. This also gives customers piece of mind when purchasing a product so they know it has not been altered.

T-Perforation – The perforation is used as an “easy to remove” tamper evident band.
