The choice of machine winding film is generally divided into two levels, the first level is that it can be used, most of the winding film personnel also stop at the first level, can be used as a more basic function, because the packaging effect is so-so, the relative cost of packaging will also be higher. Generally, these two issues have not been taken into account. One is that the waste of packaging materials in the company is very large. It is far from enough to consider the possibility of use. We need to be able to use it well and use it well while satisfying the packaging can also save costs, which is a well qualified buyer should do, which is the second level, we look at the procurement needs to pay attention to the following points:

1. The cheaper the unit, the better

Although the winding film is priced according to kilograms, it is actually used according to the number of meters when we use it. If a winding film of the same weight can pack 50 products and a kind of packing 100 products, and the unit price is almost, it must be a large number of packaging products with cheap, and our procurement often ignore this point, to put it bluntly, is cost-effective problem

Because the core performance of the machine-used winding film, high drawing ratio winding film means more saving, and energy saving, but the winding film with high drawing ratio must be used in the same drawing ratio pre-drawing winding machine to show its performance better, because only fully stretching winding film can be more economical, its stretching and retracting force can be fully reflected, the goods can be packed more solid, more beautiful appearance

4. retraction

The retraction force of the winding film is a very important technical parameter, and the retraction force is not fully reflected without sufficient stretching, so even if the film is of high quality, it does not show its superiority, so we buy winding film must first understand the winding machine stretching ratio, the two to match up, so as to be able to pack a beautiful product.
