Industrial Shrink Wrapping Process – Basic things you should know



Shrink wraps have multiple applications in the industrial sector, and there are many types of shrink wraps. To find out which type and application is best for your business, you have to first become familiar with the basics of the industrial shrink wrapping process.

What is Shrink Wrapping?

Shrink wrapping is where you package a product for shipping using a plastic wrap. The type of wrap used depends on the purpose that you need the wrap for. If you plan on just storing a product outside you would use a different wrap to the one used for protection during shipment.

Types of Shrink Wrap

Just like any other packaging there are a variety of shrink wraps to suit all your different needs. This is so you are able to find a solution for your shipping needs. You can get stretch film in both hand rolls and machine rolls. This means that it is suitable for small sized businesses as well as the larger ones. Here are a selection of shrink wrapping options available:

Builder’s Film – Like the name suggests, this type of wrap is mostly used by builders. As this wrapping is strong, it is used to cover supplies and other things at a building site. It can also be used as an underlay.

Heat Shrinkable Pallet Bags – Used to cover the contents on a pallet. The bags come in a variety of thickness, heights and lengths. They are usually on a roll and perforated for ease of removal. They are great for irregular shapes and heavy pallets as it can be shrink wrapped.

Polythene Film – An excellent option for a drop sheet when painting or trying to keep things dry. The polythene film comes in different sizes and thicknesses to suit your needs.

Polythene Tubing – Like the polythene film, the tubing comes in rolls of varying thickness and sizes. The main difference is that it is a flat tube and not a flat wrap. This means it can be used as packaging. The tubing can also be used with a variety of seals, be it heat, tape or even staples.

Stretch Film – The elastic ability of the stretch film makes it great to wrap your products tightly. The rolls of stretch film come in cast and blown varieties. They can be used manually as well as with a machine.

Shrink Film – Named shrink film for its capability to shrink when heated, they can be made of PVC or Polyolefin. You can buy shrink film in a single sheet or in a roll.

Application of Shrink Wrap

Generally there are three ways that you can apply shrink wrap. The application that you choose depends on the object shape, size and what it is going to be used for. One thing to remember is that shrink wrap will not fuse to other materials, it will only stick to itself. You may want to make sure that there is enough padding to ensure that the shrink wrap does not get punctured or chafe.

  1. Perimeter Strapping – This application uses a framework (e.g. cord strapping and buckles, scaffolding, pipes) to secure the shrink film to. This type of application is often used to cover boats during storage at winter.
  2. Total Encapsulation – This is often used on smaller objects as it is easier to cover the whole surface area. Larger items can be covered using this application, however they will need to be lifted to ensure that the bottom is also covered.
  3. Tape Adhesion – When you need to cover only a portion of an item you will most likely use this application. This is where preservation tape or shrink film tape is used to stick the shrink film to the item. Heat is then applied to make the film shrink around the object.

There is an aspect of training and experience that is necessary when applying shrink wrap. This is to ensure that the area is assessed properly when using the heat gun. The heat gun outputs high levels of heat, so it is necessary that there are no flammable materials that could combust.
