The stretch film is used as a packaging material, which can be better transported and used. It not only has the effect of dustproof and anti-theft, but also prevents smashing. Therefore, the thickness of the product is very important, and its The thickness is mainly at the time of packaging, it can better ensure its safety, so is it to say that the thicker the film, the better? Connect us to explain it to everyone reasonably.

(1) Assuming that the thickness of the stretched film is relatively large, it is difficult to stretch at the time of stretching, especially for the hand film, which in turn reduces the duty efficiency.

(2) The film with a larger thickness has a lower viscosity. The viscosity of the film is its own characteristic. In the consumption, after adding a plasticizer such as DOV, the thick film has different requirements in the consumption process, and it should be changed in the consumption formula, which will lower the film. The self-adhesiveness also reduces the overall quality of it. For example, the rare hand film on the market is 0.02mm thick, and the conventional thickness of the machine film is 0.025mm. For each thickness of 0.01mm, the machine function of the film will drop by about 5%.

Of course, after adding thickness, the machine function of the film is sacrificed, but the safety factor of the initial maintenance layer of the stretched film is enhanced, and the thick packaging is more secure with respect to the safety of the product.

Today, 0.06mm is the standard for film thickness. The wider the width of the machine, the harder it is to reach the standard thickness of the film. Since the film is a cast film, it will become thinner and thinner during the casting process. Some machines are relatively easy to control in terms of thickness.

Therefore, the stretched film is not as thick as possible. When selling, you should try to buy regular goods. Unconventional goods, the price is high, and the quality is not as shaken as the conventional film. Of course, assuming that there are special requirements, packaging materials of suitable thickness can be selected according to the theoretical requirements. However, unconventional goods are relatively high in price and the quality is not as reliable as conventional goods.

So in summary, we will find that the thickness of the stretched film is not as thick as possible, but its thickness will change with the life of the product. Therefore, when choosing the product, we should try to choose the regular product. Of course, the details should be analyzed in detail. Some time points are not confusing. Learn to be sensitive.
