What is the die-cutting process for BOPP synthetic label paper?

The die-cutting process of BOPP (Biaxially Oriented Polypropylene) synthetic label paper mainly includes the following steps:

1、 Preparation stage

Material preparation:

Choose suitable BOPP synthetic label paper as the die-cutting material.

Ensure that the quality, thickness, size, etc. of the materials meet the die-cutting requirements.

Design layout:

Design and layout according to the style, size, quantity, and other requirements of the labels.

Use professional design software or tools for graphic drawing and text layout.

Making die-cutting plates:

Produce die cut versions based on design layout. Die cut plates are usually made of materials such as metal or plastic, with cutting edges corresponding to the shape of the label.

The precision and durability of die-cutting have a significant impact on the quality of die-cutting.

2、 Die cutting stage

Positioning and fixation:

Fix the BOPP synthetic label paper onto the feeding device of the die-cutting machine.

Adjust the position and tension of the feeding device to ensure that the label paper remains flat and stable during the die-cutting process.

Die cutting operation:

Start the die-cutting machine and bring the die-cutting plate into contact with the label paper.

The die-cutting machine cuts the label paper according to the shape of the die-cutting plate by applying pressure and cutting action.

During the cutting process, it is necessary to control the cutting depth and speed to avoid incomplete cutting or damage to the label paper.

Waste discharge:

The waste generated after die-cutting is collected and discharged through the waste discharge device of the die-cutting machine.

The waste discharge process needs to be kept smooth to avoid affecting die-cutting efficiency and product quality.

3、 Subsequent processing stage

Deburring and trimming:

The edge of the label after die-cutting may have burrs or unevenness.

Use deburring tools or trimming equipment to trim the edges of the label to improve its quality and aesthetics.

Quality inspection:

Conduct quality inspection on the labels after die-cutting, including dimensional accuracy, shape consistency, cutting depth, and other aspects.

Ensure label quality meets customer requirements and industry standards.

Roll up and packaging:

Roll up the qualified labels to form a roll shaped product.

Packaging and labeling according to customer needs for subsequent use and distribution.

In summary, the die-cutting process of BOPP synthetic label paper includes preparation stage, die-cutting stage, and subsequent processing stage. During the processing, it is necessary to strictly control the quality and parameters of each link to ensure that the quality and performance of the final product meet customer requirements and industry standards.
