Blown Film Plant

Introduction of Blown Film Plant Unit :-

Blown Film Plant Unit is a technology that is the most common method to make plastic  films, especially for the packaging industry. The process involves extruding a tube of molten polumer  through a die and inflating to several times its initial diameter to form a thin film bubble. This bubble is then collapsed and used as a lay-flat film or can be made into bags. Usually polyethylene  is used with this process, and other materials can be used as blends with these polymers. A diagram of a blowing film process.

The Film Blown Film Plant Unit

Typically, Blown Film Plant Unit is carried out vertically upwards, however horizontal and downward extrusion processes are now becoming more common .

This procedure consists of four main steps:

•       The polymer material starts in a pellet form, which are successively compacted and melted to form a continuous, viscous   liquid . This molten plastic is then forced, or extruded , through an annular die.

•       Air is injected through a hole in the center of the die , and the pressure causes the extruded melt to expand into a bubble. The air entering the bubble replaces air leaving it, so that even and constant pressure is maintained to ensure uniform thickness of the film.

•       The bubble is pulled continually upwards from the die and a cooling ring blows air onto the film. The film can also be cooled from the inside using internal bubble cooling. This reduces the temperature inside the bubble, while maintaining the bubble diameter .

•       After solidification t the frost line, the film moves into a set of nip rollers which collapse the bubble and flatten it into two flat film layers. The puller rolls pull the film onto windup rollers. The film passes through idler rolls during this process to ensure that there is uniform tension in the film. Between the nip rollers and the windup rollers, the film may pass through a treatment centre, depending on the application. During this stage, the film may be slit to form one or two films, or surface treated.

Advantages of Blown Film Plant Unit :-

Blown Film Plant Unit generally has a better balance of mechanical properties than cast or extruded films because it is drawn in both the transverse and machine directions. Mechanical properties of the thin film include tensile and flexural strength, and toughness. The nearly uniform properties in both directions allow for maximum toughness in the film .

Blown Film Plant Unit can be used to make one large film, two smaller ones, or tubes that can be made into bags. Also, one die can make many different widths and sizes without significant trimming. This high level of flexibility in the process leads to less scrap material and higher productivity. Blown films also require lower melting temperatures than cast extrusion. Measured at the die opening, the temperature of cast film is about 220°C., where as the temperature of blown film is about 135°C. Furthermore, the cost of the equipment is approximately 50% of a line.

Singal Layer Blown Film Plant

Singal Layer Blown Film Plant gives high output up to 280 kg/hr with thickness ranging from 8 microns to 150 microns and a maximum film width of 2500 mm. Mono layer blown film plant is a cost effective investment of producing single layer barrier films and mono layer blown film lines as well. For packaging industries that requires greater productivity in low investment and low power consumption, monolayer blown film machine is the right option as this equipment offers high speed production solution. It is an effective investment solution for packaging sector as they can get back good return on what they spend.

The manufacture of Singal Layer Blown Film Plant for products such as?shopping bags?and continuous sheeting is achieved using a?blown film?line. This process is the same as a regular extrusion process up until the die. There are three main types of dies used in this process: annular (or crosshead), spider, and spiral. Annular dies are the simplest, and rely on the polymer melt channeling around the entire cross section of the die before exiting the die; this can result in uneven flow. Spider dies consist of a central mandrel attached to the outer die ring via a number of "legs"; while flow is more symmetrical than in annular dies, a number of weld lines are produced which weaken the film. Spiral dies remove the issue of weld lines and asymmetrical flow, but are by far the most complex.

Disadvantages of Monolayer Blown Film Machine:-

Monolayer Blown Film Machine has a less effective cooling process than flat film. Flat film cooling is done by means of  chill rolls or water., which have significantly higher specific heat capacities than the air that is used in the blown film cooling process. The higher  specific heat capacity allows the substance to absorb more heat with less change in the substance temperature. Compared to cast film, blown film has a more complicated and less accurate method to control film thickness; cast film has a thickness variation of 1 to 2% versus the 3 to 4% for blown film. The resins used for casting typically have a lower melt flow index, which is the amount of polymer that can be forced through a standard die in 10 minutes according to a standard procedure. The melt flow index for cast film is about 5.0 g/10 min where as for blown film it is about 1.0 g/10 min. Consequently, the production rates for cast film are higher: cast film lines can reach production rates of up to 300m/min where as blown film lines are usually less than half this value. And finally, cast film has better optical properties, including  transparency , haze, and gloss.

The Film Monolayer Blown Film Line:-

Typically, Monolayer Blown Film Line is carried out vertically upwards, however horizontal and downward extrusion processes are now becoming more common .

This procedure consists of four main steps:

The polymer material starts in a pellet form, which are successively compacted and melted to form a continuous, viscous   liquid . This molten plastic is then forced, or extruded , through an annular die.

Air is injected through a hole in the center of the die , and the pressure causes the extruded melt to expand into a bubble. The air entering the bubble replaces air leaving it, so that even and constant pressure is maintained to ensure uniform thickness of the film.

The bubble is pulled continually upwards from the die and a cooling ring blows air onto the film. The film can also be cooled from the inside using internal bubble cooling. This reduces the temperature inside the bubble, while maintaining the bubble diameter .

After solidification t the frost line, the film moves into a set of nip rollers which collapse the bubble and flatten it into two flat film layers. The puller rolls pull the film onto windup rollers. The film passes through idler rolls during this process to ensure that there is uniform tension in the film. Between the nip rollers and the windup rollers, the film may pass through a treatment centre, depending on the application. During this stage, the film may be slit to form one or two films, or surface treated.

Advantages of Monolayer Blown Film Line:-

Monolayer Blown Film Line generally has a better balance of mechanical properties than cast or extruded films because it is drawn in both the transverse and machine directions. Mechanical properties of the thin film include tensile and flexural strength, and toughness. The nearly uniform properties in both directions allow for maximum toughness in the film .

Monolayer Blown Film Line can be used to make one large film, two smaller ones, or tubes that can be made into bags. Also, one die can make many different widths and sizes without significant trimming. This high level of flexibility in the process leads to less scrap material and higher productivity. Blown films also require lower melting temperatures than cast extrusion. Measured at the die opening, the temperature of cast film is about 220°C., where as the temperature of blown film is about 135°C. Furthermore, the cost of the equipment is approximately 50% of a line.

Disadvantages of Monolayer Blown Film Line:-

Monolayer Blown Film Line has a less effective cooling process than flat film. Flat film cooling is done by means of  chill rolls or water., which have significantly higher specific heat capacities than the air that is used in the blown film cooling process. The higher  specific heat capacity allows the substance to absorb more heat with less change in the substance temperature. Compared to cast film, blown film has a more complicated and less accurate method to control film thickness; cast film has a thickness variation of 1 to 2% versus the 3 to 4% for blown film. The resins used for casting typically have a lower melt flow index, which is the amount of polymer that can be forced through a standard die in 10 minutes according to a standard procedure. The melt flow index for cast film is about 5.0 g/10 min where as for blown film it is about 1.0 g/10 min. Consequently, the production rates for cast film are higher: cast film lines can reach production rates of up to 300m/min where as blown film lines are usually less than half this value. And finally, cast film has better optical properties, including  transparency , haze, and gloss.
