How to Obtain Excellent Quality Plastic Film? – For Laminated Packaging
How to Obtain Excellent Quality Plastic Film? – For Laminated Packaging
Laminated film is ideal for packaging food like coffee, snacks, cookies, nuts (peanuts, pistachio, almonds), others. The reason is that they protect against humidity, oxygen, aromas, fats, and light. All of these factors decompose or reduce the lifetime of the packaged product. Therefore, the protective barrier is the most critical part of the laminated film, which is made of PE (LDPE), BOPP, PET, and others.
The plastic film for lamination requires excellent quality. Thickness defects can't exceed the range between ± 4 % to ± 7 %. Otherwise, the film will lose its usefulness in the process and lead to production loss.
Design and Simplicity
Co-Extrusion Blown Film Machines are fundamental to the lamination process. For this reason, POLYSTAR designs machines to guarantee the specific properties of the film rolls used in laminated films.
The following specifications are found on POLYSTAR Blown Film Machines Extrusion lines which enhance the film quality:
- Special screw design: adapting to customers’ requirements, POLYSTAR’s team of designers and engineers improved the functionality of the screw. The design maximizes the mixing of the materials, giving you a homogeneous film from the beginning to the end of production.
- Taiwanese Air Ring and Die head: the quality of the design, control, and capacity that they provide is outstanding compared to conventional machines. As a result, there is an immediate improvement in production and thickness control.
- Stabilizer (round shape): a simple design that protects the bubble during the production process by keeping it from being damaged or marked.
- Line speed control: Improved winder technology for controlling the speed between different stages.
All these characteristics make producing high-quality plastic film rolls possible because they give customers a greater level of control over the thickness of the plastic film.
Compared to conventional machines that only have one or two quality components, POLYSTAR machines feature excellent quality and advanced technology for the production of plastic films.
The final product from POLYSTAR machines will be of high quality and will meet all the requirements for laminated films, while traditional machines will have lower quality film rolls that cannot be used for laminated films.
