THREE LAYER FILM PLANTS


Post production operations being important, our machines produce films which run trouble free on 'FFS' machines. Sealing, printability, contact clarity, impact resistance and most important blendability of various raw materials to meet the most demanding packaging requirements - which cannot be obtained from just one polymer - are being obtained through multilayer films.

Hence, multi layer films produced on three layer film plants become functionally ideal and the most cost - effective for the combination of different polymers.
 Extruders

Extruders are manufactured in

 • Size ranges from 47 mm to 58 mm diameter
• L / D ratios of 26:1
• Output range from - 105 kgs/hr to 220 kgs/hr
• Gear boxes with integral thrust housing
• High efficiency blowers, heaters insulated for safety purposes and heat conservation to achieve precise   temperature control.
• Computer designed barrier screws tailored to suit various resin grades and process requirements to ensure   maximum outputs with quality product.
• Water-cooled feed sections.
• Variable speed drives [AC/DC] sized to suit the application and output rate.
• All extruders mounted on robust platform rotating on a heavy duty slewing bearing to give jerk free    operation controlled by PLC. The platform has one / two speed AC motor to provide single or multiple    oscillation speeds to suit different line speeds.
 Dies
• High Precision dies made on CNC machines to ensure dimensional accuracy of die profile.
• Easy-use centering screws to adjust die lip gap to accurate thickness control
• Three spiral material distribution systems designed and made from best quality die-construction materials stabilized to prevent distortion due to high temperatures.
• Smooth spiral passages precision machined, mirro polished and hard chrome plated to allow uninterrupted flow of plastic melt to prevent degradation.
• Highly efficient, energy saving, insulated ceramic heaters for longer life on die zones for precise heat control		  
 Air Cooling Ring and Blower
• Film cooling system to get production efficiency and thickness regularity.
• For increased cooling efficiency and production rate, heat exchanger is   included in high output models.
• Aluminium cast aerodynamic type double lip air cooling ring with multiple   entries and circular inserts to guide air impinging on film bubble.
• Irish ring to create air cylinder along the bubble for optimum cooling.
• Membrance filter at the suction of blower to arrest dust particles.
• AC frequency variable drive for blower to control air flow as optional.
• Self centering air ring mounting on the die head enabling free movement   near the die.
  
 Bubble Guide System
• Calibration bubble guide basket of 1000 mm height.
• Single point control mechanism to adjust arms to bubble diameter.
• PTFE rings on basket arms to provide low friction to moving film.
 Take Off Units
• Collapsible flattening board with choice of:
   Wooden strips
   Aluminium rollers
   Teflon coated rollers		 to handle sticky materials
• Sturdy vertical structure will supports, adequate ladders and safety
  railings.
• Nip system - steel chrome plated roller and rubber roller.
• Pneumatic nip operation.
• Water cooling provided in steel roller for heat removal.
• Speed variation - stepless control up to 60 meters per minute through
  reduction gearbox and AC variable drive.
• Suitable balanced guide rollers to support lay flat film to winder.
• Synchronisation of nip and winder drives.
• Chain pulley block mounting provision.		  
 Control Cabinet
Fabricated from steel sheets and mounted on robust fabricated frames which houses:
• Sophisticated, process control panel with IP 20 protection
• Microprocessor based PID temperature controllers
• DOL Starter / AC variable frequency drives for Air Ring Blower
• PLC based control for Single / Two speed motor of oscillating platform
• Extruder thyristor drives with Tacho Feedback & AC frequency drives for   Nip Rolls and Winder Drums		  
 Surface Winder
• Surface, semi-automatic-two station winder
• Film winding shafts - two main [and two standby]
• Rubber coated drums having AC frequency Variable Drives
• Set of pressure-cum-pulling rollers of rubber and ebonite with AC   frequency Variable Drive
• Slitting and Trimming arrangement
• Polyband expander rolls to spread wrinkles / creases.
• Speed range:
   7.5 to 30 meters per minute
      [ infinite variation ]
   15 to 60 meters per minute
      [ infinite variation ]
• Trim conveying with blower.
  
 Optionals:
• Oscillating nips instead of oscillating platform
• Hopper loader
• Load cell for web tension control in close loop with winder drum drives
• Roller flattenning board
• Chain pulley block arrangement
