Should I Go For Shrink Wrapping Or Stretch Wrapping? What Is Correct For My Product?
HI GUYS!
This is Rupesh Shah, Founder Aarem Engineering Mumbai, we make shrink wrapping machines and stretch wrapping machines since the last 18 years.
I have been talking with my customers over the years and one fear they have shared is whether they should shrink wrap their product or should they stretch wrap their product, what is correct for their product.
Before we go into the selection of whether we should shrink wrap or stretch our product, lets quickly understand and dwell into both these concepts. In shrink wrapping you have to use a heat shrinkable film. Your product is first wrapped with the shrink film and is passed through a heat tunnel at a particular temperature and for a particular time. As the name suggests the film shrinks and tightly wraps around your product. This is shrink wrapping.
In stretch wrapping we use a stretch film. Here we stretch the film while it is wrapping your product. When the film is stretched to the required level it develops cling properties. This cling property helps the film to cling to itself and thus the product being wrapped gets tightly wrapped.
Confused??
You may say both are doing the same thing of wrapping the product tightly then why and how are they different? When do we use the concept of shrink wrapping and when do we use the concept of stretch wrapping.
So let me directly answer this question in a simple, easy to understand way. Both these concepts are used for your secondary
packaging needs.
When your product is relatively smaller in dimensions. Like if your product falls in the size range say as small as a note pad to say as big as a shipper / master carton then you should look to shrink wrap your product.
When your product size or volume is big, like if your product falls in the size range of a bundle of rope to a pallet load then you should look to stretch wrap your product.
