How to distinguish between PP film and PE film?
Polyethylene (PE), referred to as PE, is a thermoplastic resin produced by polymerization of ethylene. In industry, it also includes copolymers of ethylene with a small amount of alpha-olefin. Polyethylene odorless, non-toxic, feel like wax, with excellent low temperature resistance (minimum use temperature up to -70 ~ -100℃)

Can mobile phone film hurt your eyes? I believe this is a problem that many friends who want to put a film on their mobile phones are troubled by. Mobile phone film can protect the screen, but relatively speaking, it will lead to increased visual fatigue, dizziness, vision loss, astigmatism and so on.
How much do you know about the role of food packaging film
In the eyes of packaging designers, the first is of course able to play a role in helping sales and brand integration, but next for you to specifically introduce the role of food packaging, of course, we think that the first must be an absolute position:
What are the effects of different pretreatment methods before film printing?
The electrons or ions in the ionized plasma are hit to the substrate surface by the discharge device. On the one hand, the long molecular chain of the material can be opened and high-energy groups can appear. On the other hand, small pinholes appear on the surface of the film after hitting, and the surface impurities can also be dissociated and re-dissociated.
How to test the adhesion of PET protective film
The puller is a kind of equipment suitable for public fitness exercise. The advantage of using a puller is that the biceps is a muscle with two muscular heads, and its main function is to bend the arms. In bending the arm, another muscle is also used, the brachial muscle. The brachial muscles can only be fully exercised when doing some forearm lifting exercises, such as high lever bends or trans high lever toys.
The difference between acrylic and silicone
When you get a PET protective film product, to distinguish between the acrylic protective film and the silicone protective film, the easiest and fastest way is to scrape the protective film with the rubber surface by hand, there is no rubber and powder is silicone, on the contrary is acrylic glue, therefore, silicone is also known as powder free glue.
What is the difference between PET silicone protective film and acrylic adhesive?
Protective film has become a new era of a very important industry, especially the mobile phone protective film this piece, mobile phone screen and shell are useful to PET protective film. PET protective film is divided into PET silicone protective film and PET acrylic protective film.
How to judge the quality of PE protective film?
PE protective film manufacturers now have a lot of. PE protective film production technology level is similar. However, compared with foreign PE protective film manufacturers, there is still a certain gap in the level of domestic production technology. Generally speaking, the genuine quality of PE protective film in Japan, South Korea and Taiwan is better than most domestic manufacturers.
How to test the adhesive viscosity of protective film?
When the adhesive surface between the object and the pressure-sensitive adhesive tape is in contact with a small pressure attack for a short time, the adhesive effect of the adhesive tape on the object is called the initial adhesive.
Where are self-adhesive labels used?
Cosmetics: The label used for cosmetics has a sense of transparency and luster, and from the perspective of container recycling, there are re-unmasking and self-adhesive materials that recycle the label together with the container. In order to meet the requirements of anti-counterfeiting, the role of cosmetic labels with anti-counterfeiting function is also very important.
Protective film function
In terms of function, the protective film from the original pure anti-scratch to the emergence of functional protective film materials of Taiwan Tianxiong company has derived AR anti-reflective film, AG matte anti-reflection film, mobile phone mirror film, anti-peek film, high-definition anti-scratch film and other functional protective films.
Protective film introduction
According to the scope of application, the protective film can be used in the following areas: metal product surface, coated metal product surface, plastic product surface, automotive product surface, electronic product surface, signage product surface, profile product surface, and other product surface.
Why does blue PET film work so well?
Blue PET protective film is a PET protective film with excellent performance, stable and uniform color, high recognition, good sticking effect, and is more popular than ordinary pet protective film.
How to control the transparency of PE protective film?
About product quality PE film transparency is crucial This small series How do you improve the transparency of PE film:
Five quality problems of PE protective film
PE protective film products compared with the previous years, the quality has been greatly improved, but there are still many details to be improved, of course, in fact, the protective film products play a protective role is a short time, which is understandable, the following five aspects of the analysis of protective film quality problems:
What is the difference between PE protective film and PET protective film?
PE protective film and PET protective film contrast, before understanding the difference between PET protective film and PE protective film, we should first understand their definition. PET protective film is also known as film high temperature resistant polyester film. PE protective film is based on a special polyethylene (PE) plastic film.
What is the difference between PE material and PP material performance?
Corrosion resistance, electrical insulation (especially high frequency insulation) excellent, can be chlorinated, modified by irradiation, available glass fiber reinforcement, low pressure polyethylene melting point, high rigidity, hardness and strength, low water absorption, good electrical properties and radiation resistance; High pressure polyethylene has good softness, elongation, impact strength and permeability, and ultra-high molecular weight polyethylene has high impact strength, fatigue resistance and wear resistance.
Mobile phone life is short? How to maintain and care for capacitive touch screen?
Mobile phones, a necessity of life, are constantly innovating to meet the increasingly high requirements of modern people. Today, the entire mobile phone market is basically the world of touch screen smart phones, from the earlier resistive touch screen to the current popular capacitive touch screen, touch screen in the development of mobile phones can be described as rapid progress.
PE electrostatic film common problems and treatment methods
PE electrostatic film has brought great convenience to our life, mainly in the process of production and processing and transportation, storage and other operations, to protect the surface of the product from pollution, corrosion, scratches, scratches, etc., to ensure the original luster of the product, so as to promote product quality and economic benefits.
PVC protective film common problems
The main reason for this phenomenon is the quality of the protective film itself. First, the pressure sensitive adhesive used in the protective film does not meet the requirements. The formulation and process implementation cannot meet the technical requirements. Make its stripping force greater than cohesion; Second, the corona strength of the substrate used in the protective film does not meet the requirements. The general surface tension of the substrate is required to be between 3840dyn. If it is too small, it will make the peeling force of the protective film greater than the adhesive force resulting in degumming.
