The plastic film of the mattress must be completely torn off at different plastic film prices

Today I want to introduce you to plastic film. Its application fields are also very wide, such as beverage packaging, video packaging, medical packaging, food packaging, and agricultural floor covering film, etc. are made of plastic film, it can be said that the emergence of plastic film has changed our way of shopping. In view of such a large market for plastic films, coupled with the uneven quality of manufacturers, China has also issued a series of related testing standards, setting a benchmark for the standardized operation of enterprises. So, what is the price of different plastic films ? If you have needs in this regard, you may wish to follow me to understand the relevant knowledge of different plastic film prices .

Different plastic film prices

First, coating high barrier plastic film

This kind of film is a very popular plastic film on the market. This plastic film is made of the most advanced nano-inorganic material and polyethylene polymerized with each other. Such a manufacturing process greatly reduces the production cost of coating high barrier plastic film.

And the plastic film produced in this way is not a little toxic, and has a certain effect of disinfection and sterilization. Now this plastic film is very suitable for packaging food. This plastic film packaging can save costs and is safe and non-toxic. Generally this kind of plastic The film is used for packaging beverages, milk and other liquid perishable foods. Now the market price of such plastic film is generally between 45 yuan and 55 yuan per square meter.

Second, low density polyethylene plastic film

The cost of this plastic film is very low, but the thickness of this plastic film is not very uniform. Although the chemical stability is very good, this plastic film will produce a toxin when it passes high temperatures. The body is harmful. The insulation of this plastic film to oxygen is also very poor. Generally, the oxygen content in this plastic film after packaging is almost the same as the oxygen content in the atmosphere. Since the composition of this plastic film does not contain polar factors, our printing becomes very difficult. Even if it has the above disadvantages, this plastic film is still the most widely used plastic film on the market. The price of this kind of plastic film on the market is generally between 25 yuan and 35 yuan per square meter.

Third, nylon plastic film

As the toughest plastic film on the market, nylon plastic film has good stretchability and can better package rigid items. This plastic film has good transparency. This plastic film is easy to absorb moisture, and it will gradually decompose after it absorbs moisture, but the wear resistance of this plastic film in a dry environment is excellent. The current market price is generally between 55 yuan and 65 yuan.

Note: This price is for reference only! Due to different regions, of course, the price will vary. If you want to know more about the relevant price details, please refer to the local dealers!

Plastic film detection method

The first is the specifications and appearance of the plastic film. Since plastic film is often used for product packaging, its appearance is very important, and at the same time it also needs to meet the needs of the product. Therefore, its specifications and appearance are to be tested in detail. We want to detect the thickness of the plastic film, as well as its length and width. In terms of appearance inspection, we usually perform visual inspection under natural light. If a defect is found, use a steel ruler or caliper for measurement.

Then there is the mechanical properties of the plastic film. In this link, we have to test the tensile properties, tear properties, friction index, and heat seal strength of the plastic film. Among them, the tensile performance is to gently pull the plastic film to both sides, then measure the distance that can be stretched, and judge whether it is qualified according to the regulations. I don't think I will introduce you to the tearing performance and friction index, which is similar to this. Then there is the heat seal strength. This is how long we heat the plastic film to see how it will stick.

Finally, the entire performance of the plastic film is measured. When plastic film is used as a food packaging bag, the video must be preserved, so its blocking effect is also a very important performance for us. Among them, the function of blocking moisture is to seal the water vapor with a plastic film and measure the content of water vapor after a period of time. Determine whether the plastic film meets the requirements according to the standard. It also has the function of blocking gas. During the test, a plastic film was sealed in the middle of a container, and then one side of the container was filled with atmospheric pressure. After a period of time, check whether it is compounded according to the gas through it.

Editor's summary: The plastic film, after some processing, has a moisture-proof function, and is resistant to oxidation. It has good air tightness, can protect the product well, avoid damage, and it is relatively easy and simple to package and has a good-looking appearance.
