teach you how to choose the thickness of plastic film

plastic plastic film pe.pet plastic film is made of plastic raw materials. as a plastic sealing and insulation product, plastic film is widely used in food, chemical industry, agriculture and other fields. the emergence of plastic films has brought great convenience to people's lives. at the same time, there are more and more types of plastic films, including sealing films, greenhouse films, plastic films, sealing films, laser films, etc. closely related to everyone's daily life, more plastic films are used. due to different use scenarios, the technical parameter requirements for plastic films are also different, such as the thickness requirements of plastic films.

1. greenhouse plastic film, plastic film insulation. after covering with film, the turbidity in the greenhouse will increase as the outside temperature increases and decrease as the outside temperature drops. seasonal changes are obvious and the temperature difference between day and night is large. therefore, the main production seasons of the greenhouse are spring, summer and autumn. the greenhouse temperature can be maintained at 15-30°c for growth through insulation and ventilation. the decision should be made based on the planting products. the thicker the plastic film, the better. it still depends on the specific materials. generally, films easily absorb water vapor and condense into water droplets on the film. during use, the film "ages" due to the influence of high temperature, low temperature and solar ultraviolet rays. after the film ages, the light transmittance decreases and even loses its use value. therefore, the plastic film covering the greenhouse should be temperature-resistant and anti-aging to enhance the light and temperature in the greenhouse and the service life of the plastic film.

2. there is also a common plastic absorption film used for door panels and mobile phones. the thinner the better, because the general film is mainly directly covered with glue on the surface of the board at room temperature and pressure, and the operation speed is fast, but after one or two years, the film is easy to fall off. the difference with pvc is that the film uses a special vacuum laminating machine to adhere to the surface of the board at high temperatures, so it is not easy to fall off. pvc is completely non-toxic and odorless, and has no harmful effects on human skin or respiratory system. it is very suitable for people who are allergic to wood and paint to use pvc film packaging for furniture or kitchenware.

3. plastic film. plastic film is mainly used. there are no special requirements for the thickness of plastic film, but you must be careful when choosing plastic film. some materials and plastic films will produce harmful substances when heated, which will cause certain harm to the human body.

4. aluminized plastic film is mainly used for sealing packaging of medicine, food, etc. it has strict thickness requirements and requires certain drug and food guarantees to ensure the safety and hygiene of packaged products.

generally speaking, due to the wide range of applications of plastic films, thickness selection needs to be targeted based on the current use of each product. so, how to calculate the thickness of plastic film? the measurement unit of plastic film is: filament, such as 8 filaments, which is 80 microns thick. the thickness unit of plastic film is generally expressed in filaments and microns (um), l mm = 100 filaments, 1 filament = 10um. so, how to measure plastic film what about the thickness? how to tell the thickness of plastic film?

first of all, tools, micrometers, post-measurement gauges (instruments) and other instruments are required. according to industry standards, film thickness detection requires a professional film thickness measuring instrument. industry-standard film material thickness measurement is divided into mechanical contact measurement and non-contact measurement. secondly, it is best to invite professional and technical personnel to participate in the procurement process, because ordinary people will have deviations when using instruments to measure. install two laser sensors above and below the film sample, and fix the sensors on the bracket. then turn on the instrument and set the parameters. finally, smart instruments such as ultrasonic thickness gauges can also use plastic film thickness, which is simple to operate but expensive.
