Analysis Of The Status Quo And Procurement Problems Of The Tape Industry In Suzhou

The current status of the tape industry and procurement issues in Suzhou are clear. Packaging tape is an indispensable packaging material in the business activities of companies, enterprises and individual units, and it is also a relatively large consumable. Any business activity is to reduce costs and pursue maximum efficiency. I am here from the perspective of corporate procurement to talk about the issues that companies should pay attention to in the daily packaging material-tape procurement process! Since my production and business activities are mainly in the Suzhou area, I can only clarify the current situation and procurement issues of the tape industry in Suzhou area!　　Tape is a seemingly simple packaging material. Since tape is made of very common materials, the tape industry is an industry with a very transparent price system. However, in terms of the entire production process, it is actually a relatively high-tech industry, especially the industry scope and uses and types involved in tape are very wide. To understand tape, you must first understand the tape manufacturer. Only then can we understand the key factors that affect the price and quality of tape. At present, there are many common packaging tape brands on the market in Suzhou, but those who are a little careful will find that although the tapes on the market have many brands and different specifications, they are very similar in appearance, quality and smell. In fact, the problem is very simple. Just like a piece of cloth, it can be made into clothing of different brands. At this time, the workmanship is a problem for each enterprise, but the quality still depends on the cloth itself.　　 There are many tape factories in Suzhou, but strictly speaking, there are very few that can be regarded as enterprises. It is more appropriate to describe it as a family workshop. The manufacturing process of the tape is film manufacturing first. Since the purity of the film determines the strength and flexibility of the tape, there are not many domestic tape factories that can independently produce films in Suzhou. The next process is glue manufacturing, which is a key factor that affects the adhesion of the tape. There are currently two or three coating companies in the Suzhou area (because there are two or three coating machines, the scale can be compared to a workshop of a large company I don’t know if the glue I choose is purchased from outside or prepared by myself, but the possibility of buying is still very high. First of all, the quality and stability of the tape is really not flattering, and the price fluctuates too frequently. It is said that it changes every day, but at least it changes every week. It feels like stock speculation. However, it can be known from its smell that the method of dissolving glue is still very primitive, and the uniformity of the glue during the entire coating process is indeed not flattering. From the occurrence of the line (the part without glue) Two problems can also be seen. One is that the machine is an ancient straight-cut coater, and the other is that there are too many unidentified particles in the glue. No wonder the smell is so smelly. I really don't know what good things are inside! This kind of tape generally needs to be mixed with toner to cover up impurities, so the transparent tape has yellow and green transparency, which is also an invention. In the coating process, there is a very important factor that affects the price of the tape, which is the thickness of the tape. The coated tape is called a semi-finished product. The original price of the tape is the price of the semi-finished product, and the price of the semi-finished product is distinguished by thickness. In general, the thickness of the tape sold in the Suzhou circulation market is between 48 microns and 50 microns. For every 1 micron difference in tape thickness, the price difference is 1.5 cents/square meter. However, coating companies in Suzhou area do not have a clear standard that specifies how thick the film and how thick the glue should be used. (However, the current thickness of the tape in Suzhou area is 2-5 microns, of course, it is going down, never going up), but the coating companies in Suzhou are still very flexible, and always use thicker ones according to market demand Substandard film. The purpose is simple, it is to increase the thickness of the tape (glue is generally more expensive) to make a finished product to reduce the number of meters. It can also increase the strength of the tape, which is right for users. A semi-finished BOPP packaging tape has a width of 1.26 meters and a length of about 4000 meters (this is also the minimum order specification for printing tape). To make such a large tape into enterprise specifications, it must be divided into small tapes. This process is called stripping. Many tape factories in Suzhou have this production capacity. Three people can set up a tape factory. Therefore, if you observe carefully, you can find that many tape brands in Suzhou have no registered trademarks, no factory addresses, and no The production date (like this kind of garbage tape does not have any shelf life). I don’t know if the industry and commerce department and the Quality Supervision Bureau will go there on vacation. After years of development, the tape industry in Suzhou has developed to a point where other regions can’t match. The first is the thickness of the paper tube. I don’t understand whether Suzhou companies are buying paper tubes or tapes. A roll of less than 100 For meters of tape, use a 7 mm thick paper tube. Another is the width. After years of development and consideration, it has developed to the point where there is no one in the past and no one in the future. It is always getting narrower and narrower, but it is regularly reduced. Generally, it is difficult to find without careful comparison, so the specifications Many are dazzling. Another thing I really don’t understand is that you can’t know the true length of a roll of tape. According to reason, this is the right of consumers. I can tell you what 800 yards and 5000 yards are. I am afraid that the world's most professional adhesive products The company-3M in the United States is going to be depressed. Is there such a big finished packaging tape in the world? In fact, these practices have only one purpose, and that is to cut corners as much as possible.　　 After a brief introduction of the production process of tape, the company has a certain amount of reference in the selection process, but how to choose the specifications and suitable products that suit your company? Generally, companies purchasing tape will choose the specifications of the tape according to the characteristics of their packaging, but few companies have a standard for tape procurement, and there is no clear requirement for the relevant physical and technical indicators of the tape. It is generally reflected in the requirement that the price is low and cheap. In terms of its simple concept, it is actually this kind of thinking that has led many small workshops to resort to fraudulent methods. Below I can tell you the basic technical indicators of a tape: Product name: BOPP packaging tape Substrate: BOPP biaxially oriented polypropylene film Adhesive: Acrylic glue ● Total thickness…………52um● Initial adhesion……… ……… 18#● 180° peeling force (for stainless steel plate) ……………… 0.65kg/25mm● Retaining force……………… 24hrs● Tensile strength……………… 30N/cm● Extension Elongation rate………………More than 180% of the data is tested according to GB4852-84, GB-2792-81, GB-7753-84 and other test methods, which are reliable test results.　　 Nowadays, many companies lack professional knowledge of packaging tape, so it is easy to be led into a misunderstanding when buying tape, and because of their own imagination, it is easy to cause companies to cut corners. Therefore, companies should pay attention to the following aspects when purchasing packaging tape. 1. Smell the smell, if the smell is very strong, there is a sour smell, the holding power of this kind of tape is very poor, especially in the low temperature environment, it will crack when it basically sticks to the carton. The stronger the smell, the initial stickiness is still Very sticky, but soon the adhesive surface will become dry and lose its adhesiveness. At that time, there will be cracks on the surface of the tape. Because of uneven glue application.　　 Second, look at the brightness of the film, generally inferior tapes are dark in color, the probability of this kind of tape breaking is very high, and the strength is poor.　　 Third, the thickness of the hand-feeling film is generally inferior to the tape that feels hard, and the actual number of meters will be reduced due to the thickness of the film. The films selected for good tapes are relatively soft and stretchable by hand.　　 Fourth, look at the color. Generally, the whiter the color of the transparent tape, the less impurities in the tape to ensure normal adhesiveness. The tape below 100 meters has a certain degree of transparency and the paper tube can be seen. For yellow tape, see if there are irregular white spots on the surface of the tape. What can't be wiped off by hand is the mark of impurities or glue. This kind of product generally has an odor.　　 5. Look at the paper tube: The use of thick paper tube tape is generally to mislead consumption. The production of tape started from abroad, so the inner diameter of the paper tube of the tape is uniform 7.6 cm, but the inferior tape has done enough work on the thickness of the paper tube, and this situation is still related to many consumers. Yes, many people think that the thicker the paper tube and the larger the outer ring, the more the tape will roll. It seems to be correct when you hear it fiercely. Can you actually calculate it carefully? Let’s say that a 3mm paper tube is compared with a 7mm paper tube. If the thickness of the pure tape from the outer diameter of the paper tube to the edge of the tape is 1 cm, we can use a mathematical formula to calculate the comparison of the 7mm paper tube. How many meters of tape can be added to a 3 mm paper tube per 1 cm of adhesive thickness? If the thickness of the tape is the same, we can easily calculate it from the above picture. The 7mm paper tube is 4mm thicker than the 3mm paper tube, which means that the diameter is 8mm longer. Converted to meters is 8÷1000=0.008 meters, which is converted to perimeter. How many meters of tape for a 7mm paper tube is more than that for a 3mm paper tube? That is 3.14×0.008=0.02512 meters. How many loops of tape are there in the thickness of 1 cm? As we said above, the total thickness of the tape is 50 microns, but for those tapes doped with impurities, then everyone should understand why the impurities are doped! 1 cm = 10 mm = 10000 microns, that is to say, 1 cm of pure adhesive tape is rolled 10000÷50=200 turns. How much more tape does the 7mm paper tube have than the 3mm paper tube? We can calculate it by multiplying the number of meters per lap by the number of laps=200×0.02512=5.024 meters, which means that a tape with a 4 mm outer ring is actually only 5 meters thicker per centimeter, but If the comparison is only from the outer diameter, the difference in tape size is very large. No wonder everyone wants to make the paper tube bigger, the purpose is not to reduce the tape rolls.　　 Conversely, if two paper tubes with different thicknesses have the same size, how many meters will the 4 mm tape between the 3 mm paper tube and the 7 mm paper tube be rolled into tape? We can also calculate it. First, calculate the outer diameter and circumference of the paper tube = the inner diameter of the paper tube + the thickness of the paper tube × 2. The outer diameter of the 3 mm paper tube is 76 mm + 3 mm × 2 = 82 mm = 0.082 meters. The outer diameter circumference is 3.14×0.082=0.2574 meters. When the tape is rolled to the thickness of the paper tube 7 mm, the outer diameter is 76 mm=7 mm×2=90 mm=0.09 meters, and the outer diameter circumference is expanded to 3.14×0.09=0.2826 meters, we take the average value, which means that the length of each round of tape is (0.2574+0.2826)÷2=0.27 meters. The 4 mm (4000 microns) thickness in the middle, the number of turns we can take is 4000÷50=80 turns. How much tape is that? 0.27×80=21.60 meters, it is easy to compare whether a large paper output tube is beneficial or unfavorable to consumers. If it is a tape with a width of 6 cm, for consumers, 21.6 meters is 0.06×21.6=1.296 square meters. According to the current cost price of tape, it is 0.88 yuan/square meter, which means that every roll of tape is paid by consumers. Pay 1.14 yuan more. For an enterprise, this long-term consumption is a huge loophole. In fact, everything is very simple to think about carefully. The paper tube is also made of a material. The thicker the material, the higher the value. Of course, it is much cheaper than the tape. (The paper tube is 1 mm thick, the price There is an increase of 0.4-0.6 yuan per meter. Many friends may think this is nothing. The 1 meter long 7 mm paper tube is about 1.6 yuan more than the 1 meter long 3 mm paper tube. Now companies generally use 45 mm wide tape , Generally 60 rolls per box, that is 2.7 meters, equivalent to RMB 4.32 per box, this cost is too cost-effective compared to the short tape, but as a consumer, I don’t think who is paying for the cost. More to say) As a tape manufacturer to choose to increase costs, it is of course purposeful, but not all tapes can be used with small paper tubes. Generally, 4 mm is used for tapes over 200 meters. The pure thickness of the tape is When the thickness is about 2 cm, because the larger the tape, the greater the pressure on the paper tube, so it is necessary to increase the strength. If you find those tapes with more than 5 mm paper tubes on the market, basically you don’t need to choose, because the thicker the The more inconvenient it is when manually packaging. In particular, many companies use tape cutters for packaging. Because the paper tube is too thick, the actual use of tape decreases, thereby increasing packaging costs. Sixth, look at the tightness, the tape is used for slitting and winding from the semi-finished product to the finished product. There is a certain tension. If the tension is large, the tape will be wound tightly. The tape should be rolled neatly according to the convention. This kind of tape has no gaps, and the degree of glue and air combination is small, which can extend the shelf life of the tape and retain the adhesive force of the tape to the maximum. In addition, for inferior tapes, because they contain impurities, the glue is unevenly applied. There will be no problems at the time after winding into a finished product, but gaps will begin to appear after a little longer. In addition, when the tape is tightly wound, the tape winding surface is flat during use, which is very convenient to find the opening. Maybe some friends want to ask, are the tapes produced differently? In fact, many consumer companies look at the size of the tape. We calculated earlier that a roll of tape also needs to be rolled several hundred times. The thickness of the tape is 50 microns. There is no gap between the two layers of the tensioned tape. Once the tension is relaxed, As a result, the gap between the tapes is slightly enlarged, and it is invisible to the naked eye to a certain extent. Then this roll of tape can be virtually enlarged by several millimeters in outer diameter. Don’t underestimate these few millimeters, because people have visual errors, so the two tapes will be very different in appearance. If there are gaps in the tape, you don't have to choose to buy it. That is a typical roll loose performance, so when choosing two tapes, the best way is to feel the weight.
