Its advanced design ensures superior film quality, consistent output, and reliable operation, making it an ideal choice for producing various types of bags and packaging films for both commercial and industrial applications. 
 

Key Features & Advantages

1.Premium Construction: The extruder, cylinder, and screw are manufactured from high-quality alloy steel, undergo nitrogen treatment, and are precision-machined. This provides optimal hardness, exceptional wear resistance, and strong corrosion resistance for extended service life.

2.High-Performance Screw: Features a specially designed screw with a 28:1 L/D ratio. This configuration ensures excellent plasticizing capability, stable melt flow, and high output rates, enhancing overall productivity.

3.Versatile Material Compatibility: Capable of processing LDPE, HDPE, and LLDPE, offering manufacturers flexibility to switch between materials based on production requirements without major machine modifications.

4.Wide Film Specification Range: Produces film with a thickness range from 0.008mm (8 microns) to 0.10mm (100 microns) and a maximum layflat width of up to 2000mm across different models, catering to diverse packaging needs.

5.User-Friendly Operation: Equipped with a variable screw speed control (10-100 r/min), allowing precise adjustment to optimize processing parameters for different materials and film specifications.

6.Modular Optional Equipment: Supports various add-ons like Auto Loaders, Corona Treaters, Die Rotary Devices, Air Compressors, and High-Speed Screen Changers, enabling customization to enhance automation, film treatment, and production continuity.

FAQ

Q1: What types of plastic can this machine process?
A1: It is primarily designed for polyethylenes, including Low-Density Polyethylene (LDPE), High-Density Polyethylene (HDPE), and Linear Low-Density Polyethylene (LLDPE).
Q2: What is the minimum and maximum film thickness it can produce?
A2: Depending on the model, it can produce film as thin as 0.008mm (8 microns) and as thick as 0.10mm (100 microns).
Q3: What is the "L/D ratio" of the screw, and why is it important?
A3: The L/D ratio is 28:1. This refers to the Length-to-Diameter ratio of the screw. A higher ratio provides better plasticizing (melting and mixing) of the material, leading to more homogeneous melt, stable output, and improved film quality.
Q4: Are the components wear-resistant?
A4: Yes. Key components like the extruder cylinder and screw are made from nitrided alloy steel, offering high surface hardness, excellent abrasion resistance, and strong corrosion resistance for long-lasting performance.
Q5: What optional equipment is available to enhance functionality?
A5: Optional equipment includes an Auto Loader for automated feeding, a Corona Treater for improving film printability, a Die Rotary Device for uniform film thickness distribution, an Air Compressor, and a High-Speed Screen Changer for continuous operation without downtime for screen cleaning.
Q6: How do I choose the right model for my production needs?
A6: Selection depends on your target output (kg/h), the desired maximum width of the finished film (layflat width), and the available factory space and power supply. Refer to the technical parameters table to match a model with your requirements.
Q7: Is this machine suitable for making garbage bags and T-shirt bags?
A7: Absolutely. Producing films for garbage bags and vest-type (T-shirt) carry bags is a common application for this versatile film blowing machine set.
