1. Uneven film thickness

Problem analysis: Uneven film thickness may be caused by wear of internal parts of the film blowing machine, improper adjustment, or uneven materials.

Solution: First check whether the internal parts of the film blowing machine are seriously worn. If there is any wear, they need to be replaced in time. Secondly, check whether the film thickness adjustment device is improperly adjusted. If there is any problem, adjust it appropriately. Finally, check whether the raw materials are uniform. If there is any unevenness, the raw materials need to be screened and processed.

2. Bubbles appear in the film

Problem analysis: The appearance of bubbles in the film may be caused by insufficient drying of the raw materials, excessive extrusion temperature, or excessive inflation ratio.

Solution: First, make sure the raw materials are fully dry and avoid using raw materials containing too much moisture. Secondly, adjust the extrusion temperature appropriately to avoid excessive temperature causing decomposition of raw materials. Finally, the blow-up ratio is appropriately adjusted to reduce the possibility of bubbles in the film.

Film blowing machine selection and precautions


1. Select suitable raw materials: The working principle of the film blowing machine is to heat the plastic particles to a molten state, and then extrude the film through the die. Therefore, it is very important to choose suitable plastic raw materials.
2. Control the speed: The speed will also affect the thickness and quality of the film, and appropriate adjustments need to be made for different products.
3. Keep the die head clean: The die head is the core component of the film blowing machine and needs regular cleaning and maintenance to avoid affecting the quality and output of the film.
4. Control the melting temperature: The melting temperature will affect the thickness and quality of the film. Generally speaking, if the melting temperature is too high, the film will deform, and if the melting temperature is too low, the film will become brittle.
5. Control the tension: After the film is produced, the tension needs to be controlled by a tensile machine to avoid wrinkles or deformation of the film.
6. Control the air blowing volume: The air blowing volume will also affect the thickness and width of the film, so it needs to be adjusted according to different product requirements.
