POLYSTAR - How to Obtain Excellent Quality Plastic Films for Lamination?



Laminated film is an excellent application for packaging food like coffee, snacks, cookies, nuts (peanuts, pistachio, almonds), and others. It is ideal for packaging because laminated films have protection from humidity, oxygen, aromas, fats, and light. All these factors decompose or reduce the lifetime of the packaged product. For this reason, the protective barrier is the most important element in the laminated film, which is composed of PE (LDPE), BOPP, PET, and others.

 
It is essential for laminated films to have excellent quality. Thickness defects can't exceed the range between ±4% to ±7%. If this happens the film will lose its effect in the process, which will be representing a cost lost for the producer.


 
Design and simplicity
Co-Extrusion Blown Film Machine plays a fundamental role in the lamination production, providing plastic films with the optimal properties to simplify the process. Polystar designs machines to secure specific properties for the film rolls used in laminated films.
Co-Extrusion lines from Polystar have certain specifications, that will provide an improvement of the film quality. Some of these are:
  • Special screw design: adapting to customer’s necessities, Polystar designers and engineers improved the functionality of the screw. The design optimizes the mixing of the materials, giving you a homogenous film from the beginning of the production to the end. 
  • Die head and Taiwanese Air Ring: the design, control, and capacity that they provide in production are excellent compared to conventional machines. From the start, it becomes a simple step towards an improvement in production. Giving films with a high-quality thickness.
  • Stabilizer (round shape): a simple design that helps in the production process, because it protects the bubble from being marked.
  • Line speed control: Improved winder technology to control the speed between different stages.

These characteristics produce high-quality plastic film rolls because each of these elements gives customers better control over the thickness of the plastic film. 
We emphasize the components of Polystar machines because they provide excellent quality and advanced technology for the production of plastic films, unlike conventional machines that only have one or two quality components. 
 
 
The final product in Polystar machines will have high quality and will fulfill all characteristics of laminated films. On the other hand, in conventional machines, film rolls will have lower quality and can’t be used for laminated films. 
 



POLYSTAR Blown Film Machines (Co-Extrusion)
If you are a producer of laminated films, Polystar recommend:

 
  Bi-X 55-55-1500 AB Co-extrusion Tri-X 55-65-55-1700 ABC Co-extrusion
Number of extruders 2 3
Layers 2 3
*Production capacity 90~160 kg/hr 180~300 kg/hr
*Maximum width 1600 mm 2400mm
 
*Depends on the model, material, width, and optional devices in the Machine.

You can use both models to produce plastic films that will be used for laminated films. The quality produced by these machines is impeccable. 
Polystar also gives the possibility to customize machines adapting to your necessities.
Customers are satisfied with the production capacity of the Blown Film Machines, not only for the good quality of the film but also for the cost-saving that these machines give them. Polystar Co-Extrusion lines are operating around the globe, and it is possible thanks to the excellent Polystar Machines components.
