Online, November 8, 2012 (Newswire.com) - In packaging units, stretch films are widely used. In modern day with the latest technology improving so much, there are many different types of stretch film available in the market. So it is necessary to make sure that the purpose is solved for which the Blown Film is manufactured. It is difficult to make choice, but still the choices are made on various factors. Some of the factors considered while selecting blown films include quality of the product, wrapping size, the performance of the product and last, but not least the cost incurred in producing the blown film.

Blown film extrusion process is used to manufacture blown films. Plastic bags and sacks are manufactured using the blown films. This process of manufacturing blown films starts when the melted plastic material is extracted by using a ring shaped die to make a continuous tube of plastic, which is mixed with the air at the same time and we form a plastic bubble. This bubble is maintained in the same form by applying constant pressure throughout the manufacturing process.

Then this bubble through the use of various roller-coasters is taken to the place where it is cooled by air and converted into a solid film tube of the required thickness. A large quantity of force is used to stretch the Blown film.

As we know the importance of stretching the Blown film, so there are a large amount of pumps and machines are used to stretch the blown film and make sure that there is no air bubbles left between the films. We require a large amount of power and a high intensity force to make sure that the blown film does not return to its original shape and make the process of stretching a mere waste of time.
