As we all know, machine stretch film is formed to use machine stretch or manual stretching, it is formed by the stress deformation of the package, because it is packed very tightly, so it is very good for the transportation of goods, in the package to see if it is clean and free of impurities, dirt, etc.
The reason why machine stretch film can wrap goods tightly is because the manufacturing process to use imported resins combined with advanced cast films. This method is characterized by better film stretchability. Moreover, it is very tough and tears easily. However, it is necessary to ensure that the ends of the paper tube are properly aligned during the wrapping process to ensure that there are no deviations during the wrapping process.
The to use of machine stretch film is very common in packaging for chemical, food processing, electrical and mechanical products, etc. because many of its properties are well recognized. When packaging products in these industries, it is important to ensure that there are no diamond corners in the product to avoid scratching the film.
Many people start to question if there is something wrong with the quality of the stretch film, but they don’t know. So what is the reason for cutting your hand?
Next, let me give you a brief introduction on how to use it.
In fact, the main reason for scratching hands in the process of using stretch film is that the middle part of the wrap film is made into a hollow paper tube, and most people who to use it will habitually put four fingers inside to roll the stretch, so that it is easy to scratch hands during the rotation of the wrap film. Although the product is transparent, beautiful in appearance, clean and bright. The quality has also improved, but there are some drawbacks in the process of using it.
Therefore, in order to avoid injuries, Bian Xiao recommends wearing gloves and hands as much as possible when using so that the paper tube does not rotate directly with your hands. This can avoid some problems.
Method 1:Try to wear gloves to protect your hands during the to use of stretch film, which can avoid the direct friction between the paper tube and your hands.
Method 2: When using stretch film in parallel, you can choose to insert a short stick into the stretch film paper tube and rotate it with the short stick.
Method 3: When most stretch films are to use vertically and need to be stretched, we can put the paper tube on the lower palm of our hand and rotate it. You can hold it in the palm of your hand when stretching, which will reduce the cutting of your hand.
The better way to operate stretch film correctly.
Many users report that they are easily injured when using pe stretch film, especially in the process of product packaging. If you often to use the product quickly, it is easy to scratch your hand and cause hand injury. In fact, this problem can be avoided. Let’s see how to avoid it.
Try to wear gloves to protect your hands in the process of to use stretch film, so that you can avoid the direct friction between the paper tube and your hands.
When using PE stretch film in parallel, you can choose to insert a short stick into the stretch film paper tube and rotate it with the short stick In the process of to use stretch film, most of them are used vertically and need to be stretched. We can put the paper tube on the lower palm and rotate it. When stretching, you can hold it in your hand, which will reduce the phenomenon of cutting your hand.
3、Stretch film is self-adhesive film
Stretch film is a double-sided film containing self-adhesive properties, and such adhesion exists only between the film and the film, with high tensile strength, better self-adhesive properties and high transparency.
It is a single-sided or double-sided adhesive plastic film, which can stretch and wrap the packaged material very tightly, and the self-adhesive adhesive does not adhere to the surface of the packaged material, but only exists on the surface of the film and the film. It has high tensile strength, high elongation, good self-adhesiveness and high transparency. It is widely used in export, bottle making, paper making, hardware and electrical appliances, plastic, chemical, building materials, agricultural products, food and other industries.
To sum up, stretching the stretch film before the wrapper can not only improve the tensile properties, but also change its puncture resistance and viscosity.
