The use of plastic bags greatly facilitates the transportation industry, especially the safety guarantee in express transportation. There is no certain standard for the size and specifications of the back plastic bag, and the manufacturer can produce a variety of bags according to the specific requirements of specific customers. The only thing to worry about is that it may cause some pollution in a wide range of applications.In daily life, there are many uses of plastic-backed bags, but people don’t know much about plastic-backed bags. In life, we must all know the envelopes we often use to send letters, but the envelope type made of paper cannot Waterproof, which leads to no way if we want to post some liquid things, so at this time we'd better choose a back plastic bag for packaging. As we said before, the safety of paper envelopes is not very good, and plastic bags can improve this situation very well.First introduce the lower back plastic bag. The back plastic bag is a special kind of bag. The body of the bag is generally made of PE or PP material, and the back is glued or self-adhesive. It can be easily attached to the object The surface, no matter what material, such as plastic, metal, etc., can be adhered firmly. In the logistics express industry, adhesive bags are used to stick to transport items in class to facilitate many express personnel to check the goods and allow the consignee to understand the specifications of the items more clearly. Although the plastic backed bag is a small item, it has a great effect. I believe everyone has a certain understanding through this Regarding how to choose a back plastic bag, Shenzhen New Zhongnan has been engaged in the back plastic bag industry for many years and shared the following: First, choose products from regular manufacturers. First of all, we must choose a regular manufacturer, a high-quality manufacturer, and produce all kinds of products that are of high quality. Regular manufacturers provide a more comprehensive guarantee for our enterprise. Manufacturers have sound operating qualifications and are recognized by relevant state departments. Only such enterprises have production qualifications, and the quality of various products produced can be more guaranteed. The development of plastic bags in logisticsLogistics must be clear to all of us. If you want to calculate the history carefully, it may have to be traced back to the post station many years ago. Of course, at that time, the intelligence could not carry too many items in the form of small pieces. Whether it is from the modern logistics industry There are many differences between the means of transportation, the time of transportation, the goods being shipped, or the packaging materials during transportation. Among them, the frequently used plastic bags are listed here. When we need to send some more important documents or orders, using this kind of bag can protect the safety of the items being sent, of course, we must eliminate human factors.And if the plastic bag is modified again, it may not only be used in the express industry.
