Heating Shrink Decorated Bands Guide

This decorating technique utilizes a printed or unprinted film band. The band is larger than the diameter of the container, but when heated will shrink to a tight fit.

PVC – Polyvinyl Chloride (PVC) is a high density film that shrinks at low temperature ranges. The most commonly used shrink sleeve material; PVC is the easiest film to control in the shrink process. It has excellent shrinkage rates, clarity, print quality, and a wide range of both shrink temperatures and shrink ratios. PVC also has high impact strength for extra weather resistance. The scuff resistant shrink sleeve material has the lowest cost, but is also less environmentally friendly than other shrink sleeve materials currently in use.

PETG – Polyethylene Terephthalate Glycol (PETG) is a high density film with a high strength ratio and excellent clarity. While PETG is the most expensive and most heat resistant shrink sleeve material, they are the most scuff resistant, have a higher gloss, and also have a higher shrink percentage. Additionally, PETG is pasteurisable and can be recycled, an often-sought feature in today's market.

OPP – Oriented Polypropylene (OPP) has lower shrink capabilities than other shrink sleeve materials, but it has excellent clarity and it's moisture resistant. OPP works over a wide range of temperatures and offers superior printability and graphic appeal.

Shrink bands can be printed with as many as 7 colors and retain excellent color fidelity and registration. Since the bands are applied by the customer, a single container supply can be used for several different products. Inventory is thus held to a minimum.

Shrink bands can be applied either manually or on fully automated systems. Bands will shrink to the container contour in seconds with either a heat gun or heat tunnel. Shrink band labels will not peel, or abrade. They permit 360 degrees of printable area.
