Working of Blown Film Plant in Industries

With the growing technology, various methods and materials are available for packaging in the industries. Blown film plant is commonly used in packaging industries so as to make the plastic films. With the help of circular die, the plastic is been extruded followed by bubble-like expansion. The bubble is then collapsed and used for making for bags

There are various advantages of blown film plants –

Tubing can be done in a single operation

The film width and its thickness are regulated by control of the volume of air in the bubble.

Effects like non-uniform temperature, bid trim can be eliminated and results from a flat die film extrusion

Uniform mechanical properties

Can be used in the manufacture of multi- layer films, co-extruded films for applications such as food packaging

Material Used for Manufacturing

The most common resins, polyethylene includes HDPE, LDPE, and LLDPE as wells as other materials used as blends used for a single layer or multi - layer film structure. ‘Tie Layers’ are a special type of resins been used in the case where materials do not mix together.

3- Layer Blown Film Plant

There are two types of three layer blown film plant namely as A-B-A Film Plant, A-B-C Film Plant that is been explained as follows –

A-B-A Blown Film Plant

3- Layer Film Plant (A-B-A film plant) consists of two extruders with two different sizes. The materials used in A-B-A film plant include CaCO3, LLDPE and HDPE. The outer layer A-A of the machine uses 20% of CaCO3 with LLDPE and larger percentage of HDPE. Whereas the B layer of the machine uses CaCO3 with HDPE raw material. Recycled pellets are also been used in the mixture.

A-B-C Blown Film Plant

The principle of operation includes like the formula is been set in the touch screen where the system is automatically absorbing the material. According to the formula, the weight in the cylinder is fully mixed depending on the requirement of the extrusion amount as well as the load material into the screw.
