Although the application of plastic packaging bag in food packaging has been very popular, plastic packaging bag is not only light, waterproof and moisture-proof, but also the price is relatively reasonable. In particular, the plastic packaging bag produced by composite plastic flexible packaging process has little impact on the environment, so it is the most commonly used packaging material. However, in daily life, when we buy products packaged in plastic bags, there will still be some problems in use. One of the more common problems is that the easily torn mouth on the plastic bags is inappropriate. So, how important is the easy tearing mouth of plastic packaging bag?
The most common problems about the tear opening of plastic packaging bags are as follows:
1、 The tear opening is missing. Sometimes when we get a plastic packaging bag, we find that we can't find the easy tear, and the plastic packaging bag is very strong, so it's difficult to tear it. Generally, we need scissors or other tools to open the plastic packaging bag smoothly, but we can't guarantee that we have scissors and other tools on hand. At this moment, it will be very troublesome.
The lack of easy tear opening of plastic packaging bag is generally due to the lack of comprehensive consideration in the design of plastic packaging bag. If the designer does not mark the position of easy tear opening on the plastic packaging bag, the plastic packaging bag manufacturer may also ignore it when producing plastic packaging bag. The final result is that the finished plastic packaging bag has no easy tear opening, which brings trouble to consumers.
2、 The position of the tear opening is unreasonable. Sometimes we will find that the tear opening of some plastic bags is in the middle of the bag. As soon as we tear the bag, the whole package will fall out, or the tear opening is very close to the side. After tearing the tear opening, we find that the seal of the plastic bag has not been torn at all. It is really lonely. Another problem that is easy to ignore is that if the position of the easy tear opening is unreasonable, it will lead to the easy tear opening just in the trademark, enterprise QR code, product bar code and other areas of the bag. These areas are very important to the plastic packaging bag and should be kept intact in general. If the easy tear opening is just in these areas at this time, it will be very difficult for us to identify or scan the code after tearing the packaging bag.
There are two reasons for the unreasonable position of easy tear opening of plastic packaging bag. One is that the designer does not consider the position of easy tear opening properly, and the other is that the adjustment of machinery and equipment is inaccurate when the plastic packaging bag manufacturer makes easy tear opening.
