Recently, some researchers have developed a new type of see-through film, which is a high-strength polyethylene film manufactured by fine-tuning the hot-drawing temperature, and its strength is 10 times that of conventional see-through films. Some people predict that in the near future, mobile phone screens will no longer be afraid of falling. Which of the following, if true, cannot support the above predictions. ['The maximum tensile strength of this new film is comparable to space-grade aluminum.', 'This new type of film is particularly light and suitable for a variety of small electronic products.', 'This new type of film has poor transparency and is not suitable for mobile phone screens.', 'This new type of film is cheap and suitable for large-scale commercial manufacturing.']
