How much thickness should we choose when choosing a stretched film? Can the thickness of a stretched film be selected? How should the thickness of a stretched film be selected? Generally speaking, the thickness of a stretched film is generally used and standardized by the market To decide, regarding the choice of the thickness of the stretched film, let's listen to the sharing of the technical staff of Qianghui Technology's stretched film manufacturers! 1. Stretching ...
When we use PE stretch film, we often encounter a more difficult problem, that is, the lower film of the product falls off. In this case, the use of the product itself is affected. Therefore, we need to find out the reasons and solutions. Today, the editor of Qianghui's stretch film manufacturer will tell you: 1. The phenomenon of PE film falling off:
The products made by PE stretch film manufacturers are more popular, but in the process of manufacturing products, some things need to be paid attention to, and the products need to be checked again. First of all, we need to pay attention to the cut edges of the PE stretch film are all qualified. If we are not cutting neatly when we cut it, we cannot ship it as a high-quality product, including ...
In the process of using PE stretch film, static electricity may sometimes appear. In fact, static electricity generated by stretch film is sometimes not serious. The specific situation depends on the situation. Therefore, we try to avoid the situation where static electricity is generated by stretch film. . To solve the problem, we must first know where the problem lies. So what are the reasons for the static electricity of PE stretch film? Today Qianghui Technology stretch ...
Stretch film has a wide range of applications. It is mainly used in conjunction with pallets to package entire sets of scattered goods instead of small containers. Because it can reduce the cost of bulk cargo transportation and packaging by more than 30%, it is widely used in the packaging of a variety of products such as hardware, minerals, chemicals, medicine, food, machinery, etc .; it is also widely used abroad in the field of warehouse storage Stretching ...
The barrier property is expressed by the transmission amount and the transmission coefficient, wherein the transmission coefficient is an amount that has nothing to do with the thickness of the stretched film, and can best characterize the nature of the material. The thickness of PLLA film, the amount of water vapor and oxygen transmission, and the transmission coefficient values are shown in Table 3-4. It can be seen from Tables 3 and 4 that as the stretching ratio increases from 1 to 6.5 times, the thickness of the PLLA stretched film gradually becomes thinner, and water vapor and oxygen permeability ...
How to test the physical properties of stretched film? The following stretch film manufacturers will introduce several specific methods to test the physical properties of stretched film: 1. Shorten the function test. The stretched film will slowly approach the flame. Severe shortening and non-violent shortening. Shrinking stretched films include polyester, cellulose acetate stretched film, rigid polyvinyl chloride (no shrinking agent ...
In fact, the physical properties of stretched films are special, because many factors need to be considered in the thermoforming process, so we may need to consider according to the actual situation of the product. As the physical properties of stretched films are different, we need to consider some potential factors. Let me briefly introduce to you what physical properties will affect ...
Many users are easily injured when using PE stretch film with hand, especially in the packaging process of the product, if the frequency and speed of use are too high, the hand will be easily scratched, so how to avoid problems like this? ? Let's take a look at what methods can be used to avoid hand injury using PE stretch film: 1. When using hand PE stretch film ...
