Heat-shrink Wrapping: What Is It?

The technique is not simple and easy: An object is placed in the shrink wrapping machine, and a loose film of polyolefin shrink wrap is wrapped around it. Then, heat is used to shrink the film securely around the object. The end result is clear, shiny film wrapped around the object. It is usually preferred over stretch wraps or overwraps because it is safer and stronger. It also fits the object’s shape more precisely, forming a thin, transparent layer of plastic on top.

How heat-shrink packaging machines work

The key element in this type of packaging machine is the heat-shrinking film, meaning a protective film that shrinks when it is heated by the packaging machine. Once the film is wrapped around the product, it is passed through a special heat-shrinking tunnel. This way, the film adheres perfectly to the fruit (or product) to be packaged.

Given its versatility and practicality, heat-shrink packaging fruit is now a technique used by many companies. In particular, it is recommended to companies such as greengrocers, supermarkets, mass retail and food companies, each with a packaging machine that best fits their production needs (manual, semi-automatic or automatic).

The benefits of heat-shrink packaging

The most immediate benefits of this type of packaging machine are lower costs than other types of packaging and reduced consumption. But do not underestimate the aesthetic reasons, which are particularly important in direct sales of fruit and vegetables to the consumer.

In fact, the most visible advantage of heat-shrink packaging is the possibility of creating aesthetically pleasing packages, ideal to be displayed in a showcase. Aesthetics is counterbalanced by the need for freshness of the fruit: the choice of heat-shrink is particularly suitable for appealing as well as resistant packaging. The heat-shrink packaging is therefore ideal for trays and packs of fruit and vegetable to be displayed on the counter or stored in refrigerator cabinets. The result is a safe and beautiful product to look at.

Lastly, and not to be underestimated, is the ease of storage and transport of goods packaged with a heat-shrink film: creating light and compact packages makes it really easy to move fruit from one place to another and to store it without occupying too much storage space.
