How to calculate the price of PET protective film?

It's a long story, so let's keep it short. There are two algorithms for the price or selling price of PET protective film: the first one is calculated by weight, that is, how much is per kilogram? The second is to calculate according to the area of the PET protective film, that is, how much is it per square meter?

Why are there such two algorithms? In fact, it is actually produced. PET protective film is generally used in places where thickness stability or quality requirements are not very strict, such as stretch film and wrapping film, according to the algorithm of how much per kilogram. These protective films themselves are The stretchability is particularly good, and the thickness will fluctuate greatly during processing, so the weight is used to protect the rights and interests of customers. We sell by weight, and there are many scales.

And according to how much the PET protective film is calculated in square meters, it is generally a protective film with high requirements, and the flatness, viscosity, etc. are very strict, or the material of the protective film itself is expensive, and the unit dosage is relatively small, so It is more accurate to price in kilograms.

For some special protective films, such as high temperature resistant PET protective film, polyimide high temperature protective film (high temperature tape), the fixed length of a roll is 33 meters, the quotation is based on the width, and how much is 1 mm.

Seeing this, you should understand that the price of PET protective film is calculated like this, right? In addition, there are some unified commodity quotations, etc. These are the ordinary business quotation methods.

In recent years, NB PET protective film has developed rapidly, and the price has also decreased according to the scarcity of the industry. More and more PET protective film has been popularized in various industries, and it is favored in China due to its low price. What are the development opportunities of Dongguan PET protective film industry?

PET protective film is widely used in electronics, packaging, and construction industries. my country's adhesive products grow at a rate of 10% every year, becoming a dynamic protective film in the chemical industry. Most of the PET protective films are now turning to the development of optical films. From the current statistics, the sales of PET protective films in 2018 are on the rise compared to the previous year.

The development trend of the PET protective film industry has been stable, and from the perspective of the future development trend of electronic machinery in the industry, protective films will still be used in large quantities.
