1、 Pay attention to the characteristics of the release film

Although the same substrate is used in the production of PET release films, using different release agents can result in different release film characteristics, and the fields and scope of use also have different focuses.

2、 Pay attention to the cost-effectiveness of release membranes

Although each brand's release film may have some differences in price, overall it is within a reasonable range. Therefore, in order to obtain a high-quality and affordable release film, it is necessary to compare products from multiple brands and choose the most cost-effective release film when the material, process, quality, and other aspects are the same.

3、 Based on usage

The purpose of purchasing release film is to maximize its performance and meet usage needs. No matter how good the quality of the release film is, if used in the wrong place, its performance cannot be better utilized.

4、 Look at the manufacturer

Regular PET release film manufacturers with large brands and high evaluations are generally mature in terms of technology and services, have strict requirements, and have a relatively large production scale, thus possessing a certain foundation, technicality, and scale.

5、 Look at product prices

There may be some differences in the price of PET release films from different brands and manufacturers, and there may also be significant differences in the price between domestic and imported release films.

6、 Pay attention to the scope of use of release film

The main purpose of purchasing release film for enterprises is to meet the production needs of products, so it is necessary to choose according to the scope of use of the release film to ensure that it meets the production requirements of the enterprise's products.

1、 Applied to the automotive industry

The joint progress of industry and technology has led to the mechanization of automobile production. In a car factory, there are many machines distributed between several assembly lines. These machines are inevitably subject to friction and wear during use, so buffer pads are often used at the connections of the machines to prevent slipping and shock, which can maximize the protection of the machine and reduce wear.

2、 Applied to logistics loading and unloading platforms

During the process of logistics loading and unloading, special attention will be paid to the integrity of the transported goods, and the contact between the goods and the ground is particularly critical. A larger extent may cause damage to the goods. At present, the most popular buffer pad in the market has the characteristics of good elasticity, tight texture, high temperature resistance, and strong impact resistance, which can protect goods when used on logistics loading and unloading platforms.

3、 Applied to the strengthening process of hot press

To make flooring, wooden doors, and furniture more durable, it is necessary to use a hot press to strengthen them. And in this process, buffer pads are also needed. The buffer pad will be installed between the template and the hot pressing plate to evenly transmit the working temperature and pressure of the hot pressing plate. Moreover, using a buffer pad can also make the paper veneer and substrate more tightly bonded, ultimately achieving a uniform and flat effect. In addition, the silicone cushion can also protect the template and compensate for pressure plate errors to ensure the normal operation of the hot pressing machine.

The common uses of PET release membranes are as follows:

1. Application of tape casting technology for polymer materials, such as microelectronic components

2. Substrates for the label and tape industry

3. Application of Lamination Technology in Various Multilayer Printed Circuit Board Industries

4. Production and Application of Covering Film and Pure Adhesive Film

5. PCB/PCL application

6. Application of Optoelectronic Die Cutting and Punching Industry

The quality requirements for PET release films are also different:

The requirement for PET release film in ordinary die cutting and punching is uniform thickness and stable peeling force.

The optoelectronic industry has added requirements for transparency and temperature resistance on the basis of stripping strength.

Polymer materials should not only have temperature resistance, but also take into account the corrosion resistance of chemical reagents, the stability of silicone oil, and the non reaction with other chemical products.

The application principle of the fluoroplastic release film is the same as that of the release film, which mainly plays an anti sticking role, but is different from that of the silicone oil release film. Fluorine exists in the fluoroplastic release film in the form of fluoride, and most tapes are in the form of base material plus glue. There are many kinds of base materials (PET, polyimide) of high-temperature resistant tape. The temperature of acrylic glue can not withstand the temperature of silicone glue Silicone adhesive and silicone oil release film belong to the same category as Silycon, and over time, various reactions will occur, which is adhesion.

Fluoroplastic release film is mainly used for high-temperature adhesive and silicone Double-sided tape bonding; Used for gold fingers, green glue, AB glue, 3M silicone bonding, etc; Die cut into any other shape for special purposes.

Characteristics of fluorine release membrane:

1、 Fluorine plastic release film is not prone to chemical reactions, and has good temperature and humidity resistance, moisture-proof, and oil-proof properties, playing a role in product isolation.

2、 Good high-temperature resistance, smoothness, and strength.

3、 Fluoroplastic release film can prevent adhesion of prepreg and protect prepreg from contamination.

4、 The release membrane can adhere to the prepreg, but it is easy to separate the two and has sufficient density to prevent water from entering the prepreg through it.

1、 What is the silicone oil release film used for?

The commonly used release film in the manufacturing industry, also known as silicone oil film. The application of silicone oil release film can be divided into two categories: applications in the die-cutting manufacturing industry and applications in the graphite manufacturing industry. The silicone oil release film used in the graphite manufacturing industry has the characteristics of uniform and stable release force, and can also be used as an anti-static layer according to customer standards, mainly for the rolling of graphite bare materials.

2、 What is the fluorine release membrane used for?

Fluorine release membrane, also known as fluoroplastic release membrane. This type of release film is made of fluorinated organic silicon material coated on the surface and has high temperature resistance characteristics. Compared to silicone tape, it has high-quality peeling characteristics. Fluorine release film is mainly used in high-temperature tape and gold finger composite die-cutting processing technology.

3、 What is a non silicon release film used for?

The scope of application of non silicon release films includes thermosols, HC transfer paper, micro adhesive, and release films for production and processing of micro adhesive protective films. In addition, due to its heavy peeling force, it can effectively prevent the release film from moving or falling when producing and processing extremely fine components.

4、 What is the use of anti-static release film?

In the information age, electromagnetic waves can have varying degrees of impact on unshielded sensitive electronic components, circuit boards, communication equipment, etc., leading to data distortion and communication chaos. However, the magnetic effect of current and Electrostatic induction generated by friction will have devastating consequences for various sensitive elements, instrument equipment, some chemical raw materials, etc., such as high-voltage discharge due to electrostatic accumulation of film bags, so anti-static release film is also very important.

1. Smell the taste

If the taste is strong and there is a sour odor, the retention of this protective film is very poor.

2. Paper tube

The selection of protective film for thick paper tubes is generally to mislead consumers. The production of protective film started from abroad, so the inner diameter of the protective film tube is uniformly 7.6 centimeters.

3. Check the tightness

The protective film should be rolled neatly according to convention, so that there are no gaps in the protective film, and the degree of adhesion between adhesive and air is small. This can extend the shelf life of the protective film and maximize the retention of its adhesion.

4. Look at the brightness of the film

Generally, low-quality protective film will have a dark color, and the probability of this type of protective film breaking is very high, with poor strength.

5. The thickness of the hand feel film

Hard protective films are generally inferior, and due to the thickness of the film, the actual number of meters will decrease. The films used for good protective films are relatively soft and have good elongation when pulled by hand.

6. Look at the color

Generally, the whiter the appearance color of the transparent protective film, the less impurities in the protective film, in order to ensure the normal adhesion of the protective film. Protective films below 100 meters have a certain degree of transparency that can be seen in the paper tube.
