How to Choose the Best Configuration for a Blown Film Machine?

When selecting a blown film machine, you should consider the following factors:

1. Production Capacity

Choose a blown film machine that aligns with your production needs. For instance, if you require producing large-sized films, opt for a machine with a wider width. Similarly, for thinner films, select a machine with a higher blow-up ratio.

2. Raw Materials

The quality of the blown film machine depends significantly on the raw materials used. Select materials that suit your needs, such as LDPE/HDPE/PBAT+PLA. Additionally, consider factors like material density, melting point, and heat resistance.

3. Ease of Operation

The ease of operation of the blown film machine influences production efficiency. Opt for machines that are easy to operate and maintain to reduce operational complexities and lower production costs.

4. Energy Consumption

Consider the energy consumption of the machine. Machines with lower energy consumption can save costs and promote environmental sustainability.

5. Price

Lastly, consider the price of the blown film machine. Balance the price with the aforementioned factors to choose a machine with the best value.

Selecting between high-end and low-end configurations of blown film machines involves options like automatic features such as automatic traction screen changing, material suction, air-inflated shaft winding, and fully automatic winding.

Recommended features for "High-Low Pressure Blown Film Machine"

1) Automatic material suction

2) Cast aluminum heating ring

3) Air-inflated shaft

4) Rotating die head device

5) Dual-position winding device

The machinery of a blown film equipment primarily consists of a frame, extruder, blown film die head, traction unit, and winding unit. The frame serves as the support structure, while the extruder melts and conveys plastic material to the blown film die head. The compressed air within the die head forms the plastic material into a film, and the traction and winding units are responsible for pulling and winding the film.

When purchasing the blown film machine, consider the following aspects:

1. Equipment Model

Choose a suitable model based on production needs. Different models vary in production capacity, applicable materials, and production processes.

2. Material Adaptability

Consider the equipment's compatibility with different materials, such as LDPE/HDPE/PBAT+PLA, among others.

3. Production Process

Different blown film machines cater to various production processes, such as single-layer film or multi-layer co-extrusion. Select the equipment aligned with your specific production needs.

4. Equipment Precision

Machines differ in precision, so choose one that matches the precision requirements of the films you intend to produce.

5. After-sales Service

Opt for a manufacturer with reliable after-sales service to ensure prompt maintenance and support in case of issues.
