The Difference Between Shrink and Stretch Wrap

Posted on - 25th January 2021

While a wooden crate can be seen as the most important part of shipping goods, other materials can be just as crucial - including shrink and stretch wrap.

One of the most important parts of making sure your custom crate makes it to its destination in one piece is the use of plastic wrap, which we supply at Centurion Packaging.

There are two different kinds of plastic wrap which can be used in packaging in shipping; shrink and stretch wrap. While they both appear very similar, they actually have different functions and can be used in different scenarios, which will we explain in this blog.

Shrink Wrap Explained

Shrink wrap becomes smaller to fit the form of the custom crate it is protecting. The plastic layer of protection is placed around the item, heat is applied and the plastic conforms to the shape and size of the package.

It has a number of benefits, such as creating a waterproof barrier around the package, holding together any loose items like pallets plus protecting the wooden crate from the elements. Because the plastic is wrapped so tightly around the package it is crucial to remember that the items inside won't have any air circulation. Also, if the package will be exposed to heat during its trip, the plastic could shrink more.

Stretch Wrap Explained

In contrast, to shrink wrap, stretch wrap does not adjust to fit the size and shape of the package. Instead, it is tightly wrapped around the wooden crate to hold loose items together. It will stretch when it is pulled, as its name suggests.

Because stretch wrap does not create an airtight barrier for your package, its main purpose is to keep everything in one place.

Both types of wrap have their own benefits and applications for use.
