What should be noted when cutting BOPP synthetic label paper molds?

When die-cutting BOPP synthetic label paper, the following aspects should be noted:

1、 Choose the appropriate die-cutting method

Choosing the appropriate die-cutting method is crucial based on the characteristics and requirements of BOPP synthetic label paper. Common die-cutting methods include full cut and half cut, as well as wire cutting and offline die-cutting. For BOPP synthetic label paper, especially labels containing specific components such as LDPE, special die-cutting methods may be required, such as cutting die cutting with mother and child knife rollers, to avoid cutting adhesion and wire drawing.

2、 Adjust the parameters of die-cutting equipment

Blade sharpness: Ensure that the die-cutting blade remains sharp to improve die-cutting quality and efficiency. Regularly inspect and replace worn blades to avoid using worn-out blades for die-cutting film materials.

Die cutting pressure: Adjust the pressure of the die cutting plate to make it evenly distributed, to ensure that the depth of the die cutting indentation is consistent. This can be achieved through methods such as die-cutting the bottom plate underneath.

Equipment debugging: Before formal die-cutting, conduct equipment debugging to ensure accurate die-cutting position and avoid wasting materials.

3、 Pay attention to material properties

Material thickness and hardness: The thickness and hardness of BOPP synthetic label paper may affect the die-cutting effect. Thicker materials may require greater die-cutting pressure, while harder materials may be more prone to producing burrs on the cut.

Material surface tension: The surface tension of BOPP synthetic label paper also has a certain impact on die-cutting. Excessive surface tension may make it difficult for the material to separate during die-cutting, while insufficient surface tension may result in uneven cutting.

4、 Optimize production process flow

Reasonably arrange production batches: Based on order quantity and production demand, arrange production batches reasonably to reduce the time for changing plates and adjusting equipment.

Quality control: Strengthen quality control during the die-cutting process, regularly inspect the die-cutting quality, and promptly identify and solve problems.

Cost management: Reduce costs by optimizing production processes and using materials reasonably while ensuring quality.

5、 Safe operation

During the die-cutting process, operators should pay attention to safe operating procedures to avoid accidents. For example, wear protective goggles and gloves to avoid direct contact with sharp blades.

In summary, BOPP synthetic label paper needs to pay attention to selecting appropriate die-cutting methods, adjusting die-cutting equipment parameters, paying attention to material characteristics, optimizing production processes, and safe operations during die-cutting. These measures help improve the quality and efficiency of die-cutting, reduce production costs, and ensure the safety of operators.
