stretch film Precautions for production

stretch film Precautions for production

Stretch film contains the shock absorption stretch film, and there are a lot of small bubbles in stretch film. The effect of these small bubbles has the function of light weight and friction proof besides the effect of shock absorption, so it is more reliable in the packaging industry, and it is also more important in the manufacturing process. Especially in the process of stretch film, what do we need to pay attention to in the process?

1) to open the machine, we must first check whether the power connection is broken or leakage, check whether the instrument is damaged or abnormal, and to ensure the safety and normal of each component before opening stretch film, so as to avoid the accident in the production process.

2) check and add the lubricating oil in the reducer and air compressor, check the lubrication of the mechanical transmission parts, avoid the dry operation to damage the stretch film machine and make noise

3) in the process of stretch film operation, the operator of stretch film machine can not stand in front of the operator in order to avoid accidental injury to the operator.

4) when the stretch film is uniform, the tube can be slowly pulled by the glove, and the end of the tube is closed and the intake regulating valve is opened, so that a small amount of compressed air is placed from the core hole of the mandrel, and then the stabilizer frame, the character plate, and the roller, the guide roll and the coiling are carefully introduced. (if the embossing is to be embossed, the embossing is to be embossed. Roll).

5) stretch film increases the molding temperature, cooling air temperature and the blow up ratio in the film forming conditions, then the turbidity of stretch film increases, and the glossiness decreases, and vice versa.

6) the compressed air pressure of stretch film tube blank should not be broken, and the symmetric stability of stretch film is guaranteed, and the quality of production is ensured relatively.

7) after using stretch film, the cleaning of stretch film extruder and die can be cleaned with copper knife, rod or compressed air, but it can not damage the smooth surface of screw and screw.

The film blowing technology is also very strict in the production of the whole bubble bag. It determines the quality of the final quality to a certain extent. Therefore, we must pay attention to the accuracy of every item in the production of stretch film.
