Because many companies lack professional knowledge of packaging tapes, it is easy to be led into a misunderstanding when buying tapes, and because of their own imagination, it is easy to cause sources of cut corners. Therefore, companies must pay attention to the following aspects when purchasing packaging tape.
Let me talk about the calculation method when selecting tape. Many people do not know how to choose indicators when buying adhesive tapes, and a lot of merchants are also selling in a dim way (some of them just know the purchase price). Now there are different types of adhesive tapes such as thickness, diameter, meters and yards. The most standard is to use meters or yards. Among them, the places used by treacherous merchants are everything.
Thickness of the glue. In order to increase the thickness of the entire roll of tape, small manufacturers do not hesitate to increase the impurities. For the thickness of the tape calculated in micrometers, even the smallest impurity will increase the thickness of the tape by one generation. This is why we see that many markets have The cause of the yellowing and greening of the adhesive tape is the impurity.
The diameter is the most direct way to increase the thickness of the paper tube. Many inferior tapes have even made the thickness of the paper tube 10mm. Below is a set of calculation data and pictures. After reading it, you will know how much profit there is.
Yard count. This is the most ridiculous count. It is often seen that those who sell tape say that their yards are 1000 yards, 800 yards, and even 1500 yards. If you look around, you know that they call the yards yards, which is ridiculous. . First understand a concept is 1 yard = 0.9144 meters, using this standard tape as a reference is 300 yards 300 * 0.9144 = 274.32 meters, the glue thickness is already 37mm, if it is the so-called 1,000 yard thickness of the dealers will soon catch up with the car wheels So, what they call 1,000 yards is “purely fictitious, and any similarity is purely coincidental.” Because our people are unlikely to take the whole roll of tape apart to measure the distance, the 1500 yard standard has to come out. It’s a pitman.
First, smell the smell. If the taste is very strong, there is a sour smell. The holding force of this tape is very poor, especially in low temperature environments, it will crack on the carton when it is basically stuck. It is very sticky, but the glue surface will soon become dry and lose the glue, and then there will be cracks on the surface of the tape. Because of uneven coating.
Second, look at the brightness of the film. Generally, inferior tapes are dark in color. The probability of this tape breaking is very high and the strength is poor.
Third, feel the thickness of the film, the film is generally less rigid, and because of the film thickness, the actual meter will be reduced. The films used for good tapes are relatively soft and stretch well by hand.
Fourth, look at the color, the more transparent the general appearance of transparent tape, the less the tape impurities to ensure normal adhesiveness, the tape below 100 meters have a certain degree of transparency can see the paper tube. Yellow tape to see if there are irregular white spots on the surface of the tape. Impurity or jerky blotting cannot be removed by hand pressure. This product generally has an odor.
Fifth, look at the paper tube: the choice of thick paper tube tape is generally used to mislead consumers. 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 poor quality tape has done a good job in the thickness of the paper tube, and this is still related to many consumers Many people think that the thicker the paper tube, the larger the outer ring, the more the tape will be rolled up. It sounds right when you hear it. In fact, you can calculate it carefully. Compared with paper tube, if the thickness of pure tape is 1 cm from the outer diameter of the paper tube to the edge of the tape, we can use a mathematical formula to calculate the thickness of 7 mm paper tube compared to 3 mm paper tube. tape?
Features of printing sealing glue
An enterprise must develop its own image when it develops to a certain degree. The products produced by its own factory want to get rid of the traditional image, want to upgrade, and want to make a further step. The outer packaging is undoubtedly the first improvement. The advantages of making printed carton sealant are as follows.
One: Improve the brand image of your own factory.
Two: It can be used for product promotion, and it can also print the business contact information, address, telephone, etc. of the enterprise.
Three: Printing sealing glue can play an anti-theft role. Some customers told us before that logistics always shows that there is missing or missing goods in the box. What’s more, someone points out the defective goods. If this is the case, In this case, printing the sealing glue can serve as an anti-theft seal.
Four: Printing sealing glue can also drive your product sales. A good printing sealing glue has a beautiful appearance, grabs the attention of customers, and has a preconceived effect on your products.
