We use PE foam tape every day, widely used in daily life, industrial production is also in use, but for many businesses that have bought a lot of tape, PE foam tape quality inspection is still not well understood.

Today, Hexing engineers show you how to check the quality of PE foam tape:

Methods for quality inspection of PE foam tape.

1. First: Check whether there are cracks on the PE foam tape

When cutting PE foam tape, if your cutting tool is not sharp enough or the adjustment is not suitable, it is easy to leave cracks in the base paper or the face paper of the foam tape, and the fibers that are pulled out of the cracks will be stuck by the adhesive. Cracks occur in two ways, one is continuous, the other is random, sometimes on one side of the roll of foam tape, may also appear on both sides. Therefore, before the machine processing of PE foam tape, we should carefully observe whether there are cracks on the face paper and the bottom paper.

2, the second: test PE foam tape has no rough edge

The edge finish of the roll foam tape and no damage are the basis for ensuring the good quality of the double-sided tape. Therefore, before processing, we need to carefully observe whether the edge of the drum foam tape has a rough edge, whether there is damage due to improper delivery, roll the drum foam tape down a few laps, and carefully check its cutting edge.
