Magical use of stretch film
Magical use of stretch film
Stretch film products are popular with people. Stretch film has good tensile properties, tear resistance, penetration resistance, transparency, good self-adhesive and high shrinkage, compact packaging, not loose and so on. Let's take a brief look at stretch files.
Pre-stretching is done by two rollers. The two pre-stretching rolls are connected by gear units, and the pulling force is generated by the turntable. Because stretch film is stretched in a short distance, stretch film is not shrinkable. The original puncture performance of stretch film is also maintained. Direct stretching is completed between the tray and the winding film. If the stretch ratio exceeds 55%-60%, and exceeds the original yield point of stretch file, the film width decreases, the puncture performance also loses, and stretch file is easy to break. And at 60% tensile rate, the pulling force is also very large, for light goods, it is likely to make the goods deformed.
Stretch film has a wide range of applications, but many domains in China have not been involved, and many domains have not been widely used. With the expansion of the application field, the use of stretch file will increase greatly, and its market potential is immeasurable.
