Stretch Wrap- Blown Film (Part 1)

March 15th, 2016

What is the difference between Blown and Cast Stretch Wrap?

 

 

Today’s post is from the SafeSourcing Archive.

Within the Stretch Wrap industry, there are hundreds of thousands of SKUs of stretch wrap. Most of the stretch wrap that SafeSourcing sources are for warehousing purposes and shipping freight. When reviewing the specifications there are some things to note.

The first type of film that I will be focusing on is the Blown Film. The “blown” indicator on the stretch wrap refers to the manufacturing process that the film undergoes. There are advantages to using blown film versus cast film.  It all depends on the use that the stretch wrap is intended for.

Advantages:

  1.  Blown film is often more taught in order to keep shipments from moving during freight.
  2. Blown film is also lighter weight than cast film, making it is easier to move by individuals in the warehouse.
  3. Blown film is more durable around corners and breaks less during application.
  4. Blown film is the newer technology in the industry.

Disadvantages: 

  1. Depending on the manufacturer, blown film can be more expensive.
  2. Blown film can puncture more often.
