Multilayer blown film material is comparatively strong than two layer and mono layer blown films. It has strong impact in packaging industry as this product bears multiple protection properties including puncture and heat resistant, less or zero attraction to moisture and oxygen, etc. Multilayer Blown Film Plant is suitable for producing high barrier wrapping and stuffing material for packing food products, processed fluid consistency food items, etc. Multilayer blown film line can also be produced with this machine.


Plastic melt is extruded through an annular slit die, usually vertically, to form a thin walled tube. Air is introduced via a hole in the centre of the die to blow up the tube like a balloon. Mounted on top of the die, a high-speed air ring blows onto the hot film to cool it. The tube of film then continues upwards, continually cooling, until it passes through nip rolls where the tube is flattened to create what is known as a ' lay-flat' tube of film. This lay-flat or collapsed tube is then taken back down the extrusion ' tower' via more rollers. On higher output lines, the air inside the bubble is also exchanged. This is known as IBS (Internal Bubble Cooling). 

The lay-flat film is then either kept as such or the edges of the lay-flat are slit off to produce two flat film sheets and wound up onto reels. If kept as lay-flat, the tube of film is made into bags by sealing across the width of film and cutting or perforating to make each bag. This is done either in line with the blown film process or at a later stage. 

Typically, the expansion ratio between die and blown tube of film would be 1.5 to 4 times the die diameter. The drawdown between the melt wall thickness and the cooled film thickness occurs in both radial and longitudinal directions and is easily controlled by changing the volume of air inside the bubble and by altering the haul off speed. This gives blown film a better balance of properties than traditional cast or extruded film which is drawn down along the extrusion direction only.

Multilayer Co-Extrusion Blown Film Plant/PP Single Dia Blow

As noted, the film blow-up-ratio (BUR) will be determined from the blown film die diameter and the

desired film  lay-flat. Since it is not easy to measure the bubble diameter directly, the bubble diameter

is calculated from the lay-flat width -- the bubble diameter is 0.63 times the film lay-flat width. For

LLDPE, standard BURs are between 2:1 and 3.5:1. Bubble stability problems are typically observed if

the BUR is too high; excessively high MD/TD oriented film is produced when  the  BUR is too low.

Due to the relatively high shear viscosity of narrow molecular weight distribution resins, LLDPE resins

tend to be extruded through a wide die gap, on t he order of 90 mils  (2.3 mm) to 110 mils (2.8 mm). If

the film formulation includes a processing aid, a narrower die gap can be used. It is unusual, however,

to extrude 100% LLDPE through a blown film die gap narrower than 65 mils (1.6 mm), even with a

processing aid. If the die gap is too narrow for the resin being extruded, the film could be subject to

melt fracture, high head pressures, etc. Conversely, if the die gap is too wide for the resin being

extruded, bubble stability problems and highly oriented film can result .

The LLDPE frost line  height (FLH) is approximately the height above the blown film die where the

molten polymer solidifies. The FLH is typically controlled by the adjusting t he volume of cooling air

from the air ring. In practice, generally, the cooling air is adjusted to maximize output rate and bubble

stability. However these adjustments will also have some impact on film properties. At a lower FLH,

LLDPE film optical properties will be improved,  but t he film mechanical properties will exhibit more

MD/TD orientation. Conversely, LLDPE film mechanical properties will be more balanced, but film

clarity will suffer at higher FLHs.

There are two different types of die tooling used for coating over a wire, tubing (or jacketing) and pressure. In jacketing tooling, the polymer melt does not touch the inner wire until immediately before the die lips. In pressure tooling, the melt contacts the inner wire long before it reaches the die lips; this is done at a high pressure to ensure good adhesion of the melt. If intimate contact or adhesion is required between the new layer and existing wire, pressure tooling is used. If adhesion is not desired/necessary, jacketing tooling is used instead.

Coextrusion

Coextrusion is the extrusion of multiple layers of material simultaneously. This type of extrusion utilizes two or more extruders to melt and deliver a steady volumetric throughput of different viscous plastics to a single extrusion head (die) which will extrude the materials in the desired form. This technology is used on any of the processes described above (blown film, overjacketing, tubing, sheet). The layer thicknesses are controlled by the relative speeds and sizes of the individual extruders delivering the materials.

Two Layer Blown Film Extruder Plant, PP & HDPE Sheet Plant

Two Layer Blown Film Extruder Plant, PP & HDPE Sheet Plant

Sheet/film extrusion is used to extrude plastic sheets or films that are too thick to be blown. There are two types of dies used: T-shaped and coat hanger. The purpose of these dies is to reorient and guide the flow of polymer melt from a single round output from the extruder to a thin, flat planar flow. In both die types ensure constant, uniform flow across the entire cross sectional area of the die. Cooling is typically achieved by pulling through a set of cooling rolls (calender or "chill" rolls). In sheet extrusion, these rolls not only deliver the necessary cooling but also determine sheet thickness and surface texture.[6] Often co-extrusion is used to apply one or more layers on top of a base material to obtain specific properties such as UV-absorption, texture, oxygen permeation resistance, or energy reflection.

A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 inches typically) is highly important and greatly affects forming cycle times for most plastics.

The manufacture of plastic film for products such as shopping bags and continuous sheeting is achieved using a blown film line.[4]

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.[5]

The melt is cooled somewhat before leaving the die to yield a weak semi-solid tube. This tube's diameter is rapidly expanded via air pressure, and the tube is drawn upwards with rollers, yielding the plastic in both the transverse and draw directions. The drawing and blowing cause the film to be thinner than the extruded tube, and also preferentially aligns the polymer molecular chains in the direction that sees the most plastic strain. If the film is drawn more than it is blown (the final tube diameter is close to the extruded diameter) the polymer molecules will be highly aligned with the draw direction, making a film that is strong in that direction, but weak in the transverse direction. A film that has significantly larger diameter than the extruded diameter will have more strength in the transverse direction, but less in the draw direction.

In the case of polyethylene and other semi-crystalline polymers, as the film cools it crystallizes at what is known as the frost line. As the film continues to cool, it is drawn through several sets of nip rollers to flatten it into lay-flat tubing, which can then be spooled or cut.

The “High Stalk”  bubble shape for HDPE blown film allows more time for the HDPE film to cool before

it reaches the region where the bubble is blown out to its maximum bubble diameter. T his region

where the bubble is enlarged is where the film is being stretched primarily in the TD direction and the

TD orientation is being generated. The cooler the film is when it reaches t he top of the stalk where the

TD orientation begins to  be generated greatly increases the amount of the TD orientation

achieved in

the finished film.

“Cool” film also enhances  the amount of the TD orientation  retained in the final film. It also retards

the relaxation of the polymer molecules that were orientated in the TD direction. After the film passes

through this TD orientation region, it enters the final stage of the process where the film is traveling

from the frost line up to the nip rolls at the top of the film line tower. At this time, the film is being

stretched primarily in the MD direction. The relaxation of the polymer molecules that were oriented in

the TD direction is more difficult in “cold” film, so the TD orientation is retained better. Conversely, if

the film is “hot”, the polymer molecules can relax  easily and the amount of TD orientation in the final

film is significantly reduced.

One of the most common methods of film manufacture is Blown Film (also referred to as the Tubular Film) Extrusion. The process involves extrusion of a plastic through a circular die, followed by "bubble-like" expansion. The principal advantages of manufacturing film by this process include the ability to: 

·         Produce tubing (both flat and gussetted) in a single operation

·         Regulation of film width and thichness by control of the volume of air in the bubble, the output of the extruder and the speed of the haul-off

·         Eliminate end effects such as edge bead trim and non uniform temperature that can result from flat die film extrusion

·         Capability of biaxial orientation (allowing uniformity of mechanical properties)

·         Blown Film Extrusion can be used for the manufacture of co-extruded, multi-layer films for high barrier applications such as food packaging.

 

The Process


Plastic melt is extruded through an annular slit die, usually vertically, to form a thin walled tube. Air is introduced via a hole in the centre of the die to blow up the tube like a balloon. Mounted on top of the die, a high-speed air ring blows onto the hot film to cool it. The tube of film then continues upwards, continually cooling, until it passes through nip rolls where the tube is flattened to create what is known as a ' lay-flat' tube of film. This lay-flat or collapsed tube is then taken back down the extrusion ' tower' via more rollers. On higher output lines, the air inside the bubble is also exchanged. This is known as IBS (Internal Bubble Cooling). 

The lay-flat film is then either kept as such or the edges of the lay-flat are slit off to produce two flat film sheets and wound up onto reels. If kept as lay-flat, the tube of film is made into bags by sealing across the width of film and cutting or perforating to make each bag. This is done either in line with the blown film process or at a later stage. 

Typically, the expansion ratio between die and blown tube of film would be 1.5 to 4 times the die diameter. The drawdown between the melt wall thickness and the cooled film thickness occurs in both radial and longitudinal directions and is easily controlled by changing the volume of air inside the bubble and by altering the haul off speed. This gives blown film a better balance of properties than traditional cast or extruded film which is drawn down along the extrusion direction only.

Plastic Extrusion Process

Plastic extrusion process converts plastic materials as plastic chips or pellets from solid to liquid form and reconstitute them in final shape of finished product. Extrusion Machinery is used for gravity fed and dried in a hopper into the barrel of the extruder before going to the feed screw. Additives are mixed with resin prior to arriving at the hopper. The polymer resin is heated from the extrusion screw by heating elements and shear heating. The screw forces the resin through a die to form a desired shape from resin. The extrudate is pulled through the die or water tank to cool and solidify. A multitude of polymers are used in the production of plastic tubing, pipes, rods, rails, seals and films.

During Plastic extrusion process the material transform from solid to liquid and back again to solid form in defined shape without losing the distinctive properties with minimum scrap and degradation, have made plastic extrusion method more popular, which even reduce the recycling plastic wastage.

The manufacture of plastic film for products such as shopping bags and continuous sheeting is achieved using a blown film line.[4]

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.[5]

The melt is cooled somewhat before leaving the die to yield a weak semi-solid tube. This tube's diameter is rapidly expanded via air pressure, and the tube is drawn upwards with rollers, yielding the plastic in both the transverse and draw directions. The drawing and blowing cause the film to be thinner than the extruded tube, and also preferentially aligns the polymer molecular chains in the direction that sees the most plastic strain. If the film is drawn more than it is blown (the final tube diameter is close to the extruded diameter) the polymer molecules will be highly aligned with the draw direction, making a film that is strong in that direction, but weak in the transverse direction. A film that has significantly larger diameter than the extruded diameter will have more strength in the transverse direction, but less in the draw direction.

In the case of polyethylene and other semi-crystalline polymers, as the film cools it crystallizes at what is known as the frost line. As the film continues to cool, it is drawn through several sets of nip rollers to flatten it into lay-flat tubing, which can then be spooled or cut.

Sheet/film extrusion is used to extrude plastic sheets or films that are too thick to be blown. There are two types of dies used: T-shaped and coat hanger. The purpose of these dies is to reorient and guide the flow of polymer melt from a single round output from the extruder to a thin, flat planar flow. In both die types ensure constant, uniform flow across the entire cross sectional area of the die. Cooling is typically achieved by pulling through a set of cooling rolls (calender or "chill" rolls). In sheet extrusion, these rolls not only deliver the necessary cooling but also determine sheet thickness and surface texture.[6] Often co-extrusion is used to apply one or more layers on top of a base material to obtain specific properties such as UV-absorption, texture, oxygen permeation resistance, or energy reflection.

A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 inches typically) is highly important and greatly affects forming cycle times for most plastics.

Coextrusion is the extrusion of multiple layers of material simultaneously. This type of extrusion utilizes two or more extruders to melt and deliver a steady volumetric throughput of different viscous plastics to a single extrusion head (die) which will extrude the materials in the desired form. This technology is used on any of the processes described above (blown film, overjacketing, tubing, sheet). The layer thicknesses are controlled by the relative speeds and sizes of the individual extruders delivering the materials.

Extrusion coating[edit] 

Extrusion coating is using a blown or cast film process to coat an additional layer onto an existing rollstock of paper, foil or film. For example, this process can be used to improve the characteristics of paper by coating it with polyethylene to make it more resistant to water. The extruded layer can also be used as an adhesive to bring two other materials together. Tetrapak is a commercial example of this process.

Compound extrusions[edit]

Compounding extrusion is a process that mixes one or more polymers with additives to give plastic compounds. The feeds may be pellets, powder and/or liquids, but the product is usually in pellet form, to be used in other plastic-forming processes such as extrusion and injection molding. As with traditional extrusion, there is a wide range in machine sizes depending on application and desired throughput. While either single- or double-screw extruders may be used in traditional extrusion, the necessity of adequate mixing in compounding extrusion makes twin-screw extruders all but mandatory.[7][8]

There are two sub-types of twin screw extruders: co-rotating and counter-rotating. This nomenclature refers to the relative direction each screw spins compared to the other. In co-rotation mode, both screws spin either clockwise or counter clockwise; in counter-rotation, one screw spins clockwise while the other spins counter clockwise. It has been shown that, for a given cross sectional area and degree of overlap (intermeshing), axial velocity and degree of mixing is higher in co-rotating twin extruders. However, pressure buildup is higher in counter-rotating extruders.[9]

Multilayer films are used for varied crucial application in flexible packaging, which demand vital film properties like dart impact strength, puncture resistance, hot tack strength, gloss, oxygen and moisture barrier etc.

Multilayer blown film material is comparatively strong than two layer and mono layer blown films. It has strong impact in packaging industry as this product bears multiple protection properties including puncture and heat resistant, less or zero attraction to moisture and oxygen, etc. Multilayer Blown Film Plant is suitable for producing high barrier wrapping and stuffing material for packing food products, processed fluid consistency food items, etc. Multilayer blown film line can also be produced with this machine.

The drawdown between the melt wall thickness and the cooled film thickness occurs in both radial and longitudinal directions and is easily controlled by changing the volume of air inside the bubble and by altering the haul off speed. This gives blown film a better balance of properties than traditional cast or extruded film which is drawn down along the extrusion direction only.  


Materials

Polyethylenes (HDPE, LDPE and LLDPE) are the most common resins in use, but a wide variety of other materials can be used as blends with these resins or as single layers in a multi-layer film structure. these include pp, pa, evoh. In some cases, these materials do not gel together, so a multi-layer film would delaminate. To overcome this, small layers of special adhesive resins are used in between. These are known as “tie layers”.

Blown film can be used either in tube form (e.g. for plastic bags and sacks) or the tube can be slit to form a sheet.

Typical applications include Industry packaging (e.g. shrink film, stretch film, bag film or container liners), Consumer packaging (e.g. packaging film for frozen products, shrink film for transport packaging, food wrap film, packaging bags, or form, fill and seal packaging film), Laminating film (e.g. laminating of aluminium or paper used for packaging for example milk or coffee), Barrier film (e.g. film made of raw materials such as polyamides and EVOH acting as an aroma or oxygen barrier used for packaging food, e. g. cold meats and cheese), films for the packaging of medical products, Agricultural film (e.g. greenhouse film, crop forcing film, silage film, silage stretch film).
