How to distinguish the quality of stretch film
February 12, 2020
The stretched film has the characteristics of high transparency, high longitudinal elongation, high transverse tear strength, and good puncture performance. Widely used in the packaging of a variety of products such as hardware, chemicals, food.
The Stretch Film is used to wrap the goods for transportation. The stretch film is the deformation stress caused by the mechanical stretching device or the manual stretching of the film. It is a very common packaging form in the world. Imported resin and advanced film extrusion production process, with good tensile properties, tear resistance, strong penetration resistance, high transparency, good self-adhesiveness and high retraction rate, tight packaging, no looseness, etc. Used for single-piece or tray packaging and other Strapping packaging of chemical raw materials, fertilizers, food, electromechanical products, light textile products, stretch film sealing, low temperature and high shrinkage, high transparency and good gloss, low temperature The lower shrinkage is fast, suitable for small packaging, applied to the food field (special types of food.
The quality of the stretched film is tested. When the stretched film is used, it often encounters the problem of poor stretchability. It is easy to lead to the dissatisfaction of the package, and the main effect on the wrapped package is greatly reduced. Therefore, consumers should pay attention to the purchase of stretch film. To determine the quality of stretchability, firstly tear away from the length of the stretched film, then tear away from the transverse direction, stretch the raw Good impact is strong, and if the toughness is not good, it is easy to shred. If it is too thin, the toughness will be greatly reduced, and the stretchability will be bad.
