Release film
PET release film is also called PET silicone oil film, which is coated with a layer of silicone oil on the surface of the PET film to reduce the adhesion of the PET film surface and achieve the effect of release. Can be divided into single-sided release film and double-sided release film. According to the release force, it can be divided into light release film, middle release film and heavy release film. Commonly used thicknesses are: 0.012mm, 0.019mm, 0.025mm, 0.038mm, 0.05mm, 0.075mm, 0.1mm, 0.125mm, 0.188mm, PET release film manufacturers are equipped with large slitting, slicing machine, Divide and slice according to your specifications. PET release film is now widely used in packaging, printing, screen printing, pad printing, nameplates, membrane switches, flexible circuits, insulating products, circuit boards, laser anti-counterfeiting, lamination, electronics, sealing materials, reflective materials, waterproof Materials, medicine (paper for plaster), sanitary paper, adhesive products, die-cutting and punching processing, etc.
The release film
PET release film, also known as thermal transfer film, release film, release film, slip film, Tana paper, silicone oil film, release film, silicone oil release paper, silicone oil paper, hole masking film, PET release film is also called PET Transfer film. It is mainly used as a carrier for vacuum aluminizing, that is, after the PET film is placed in a vacuum aluminizing machine and aluminized, the glue is combined with paper, and then the PET film is peeled off, and the aluminum molecular layer is transferred to the surface of the cardboard through the adhesion effect. The so-called aluminized cardboard is formed. The production process of aluminized cardboard is: PET base film → release layer → color layer → aluminized layer → glue layer → transfer to cardboard.
High gloss film
In addition to the excellent physical and mechanical properties of ordinary polyester films, Jinlu PET high-gloss film also has excellent optical properties, such as good transparency, low haze, and high gloss. It is mainly used for high-grade vacuum aluminum plating products. The film is mirror-coated after aluminum plating, and has a good packaging decoration effect; it can also be used for laser laser anti-counterfeiting base film. High-gloss BOPET film has a large market capacity, high added value, and obvious economic benefits.
Transfer film editing
Transfer film is also called thermal transfer film. This transfer film is characterized by high tensile strength, good thermal stability, low thermal shrinkage, smooth and smooth surface, good peelability, and can be used repeatedly.
Vacuum aluminized cardboard is a kind of cardboard with metallic luster, which is a high-grade novel packaging material developed in recent years. This kind of aluminum-plated cardboard has bright color, strong metal feeling, and bright and elegant prints. It can replace the large-area bronzing of printed products and play a icing on the cake. Because it adopts vacuum aluminum plating, the cardboard surface is only covered with a thin and compact aluminum layer of 0.25um ~ 0.3um, which is only one fifth of the aluminum foil layer of the aluminum cardboard. It has a noble and beautiful metal texture, and has degradable and recyclable environmental protection properties. It is a green packaging material.
Reflective film
The characteristics of Jinlu PET reflective film is that the film has excellent optical properties, the surface is flat, smooth, good thermal stability, shrinkage rate is small, and it is resistant to light aging.
Reflective materials used in transportation facilities include lens-type retro-reflective film and flat-type retro-reflective film. They use aluminum-coated PET film as the reflective layer. After being coated with pressure-sensitive adhesive, the glass has a refractive index of 1.9 The microbeads are adhered to the PET aluminized film, and then a layer of butyral surface protective layer is sprayed and formed.
Jinlu PET reflective film is used in billboards with reflective requirements, traffic reflective signs (reflective road signs, reflective isolation belts, reflective car number plates), reflective police uniforms, industrial safety signs, etc.

Coating film
In order to improve the surface properties of the PET film, to improve the adaptability of the printing and the bonding force of the vacuum aluminum plating layer, the method of corona treatment is usually adopted to increase the surface tension of the film. However, the corona method has problems such as timeliness, especially in a high temperature and high humidity environment, the film tension after corona treatment is easily attenuated. However, the chemical coating method does not have such a problem, so it is favored by the printing industry and the aluminum plating industry.
Domestic PET chemical coating series products have been developed: if coated with water-soluble polymer, it can increase the surface tension of PET film; coated with acrylic emulsion can improve the adaptability of printing (water-soluble ink can be used); The polyurethane aqueous solution coating can strengthen the bonding force of the aluminum plating layer and the PET base film, and can increase the thickness of the aluminum plating layer. In addition, high barrier films and antistatic films can also be produced by coating methods.
Antistatic film
The world today has entered the information age. Electromagnetic waves of various frequencies and wavelengths fill the entire earth ’s space. These electromagnetic waves will cause different degrees of interference to unshielded sensitive electronic components, circuit boards, communication equipment, etc., causing data distortion, Communication disorder. The static electricity generated by electromagnetic induction and friction affects various sensitive components, instruments, certain chemical products, etc., such as high-voltage discharge due to the accumulation of static electricity in packaging films, the consequences will be destructive, so the development of anti-static PET packaging films is also very important. The antistatic film is characterized by adding an antistatic agent to the PET film to form a very thin conductive layer on the film surface and form a continuous phase to improve the surface conductivity and cause the generated charge to leak as soon as possible. Generally, the surface specific resistance of the antistatic film is ≤109 ~ 11 ohms.
Heat sealing film
Ordinary PET is a crystalline polymer. After stretching and orientation, the PET film will produce a large degree of crystallization. If it is heat-sealed, it will shrink and deform. Therefore, the ordinary PET film does not have heat-sealing properties. In order to solve the problem of heat sealing when PET film is used for product packaging, the method of compounding BOPET film with PE film or CPP film is usually adopted, thereby limiting the application of BOPET film to a certain extent.
In order to solve the problem of heat sealing, through the modification of PET resin and the use of A / B / C three-layer die, a three-layer co-extruded heat-sealed PET film has been developed. This heat-sealed PET film Because one side is a heat-sealable layer, it can be directly heat-sealed, which is very convenient to use.
Heat-sealed PET film can be widely used in the packaging of various commodities and card protection film and other fields.
Heat shrinkable film
Polyester heat shrinkable film is a new type of heat shrinkable packaging material. Because it has the characteristics of easy recycling, non-toxic, odorless, good mechanical properties, especially in line with environmental protection, polyester (PET) has become an ideal substitute for replacing polyvinyl chloride (PVC) heat shrinkable film in developed countries.
However, ordinary polyester is a crystalline high polymer, and ordinary PET film can only obtain a heat shrinkage rate of less than 30% through special processing. To obtain a higher heat shrinkage polyester film, it must also be modified. That is to say, in order to prepare a polyester film with a high heat shrinkage rate, it is necessary to copolymerize and modify ordinary polyester, that is, polyethylene terephthalate. The highest heat shrinkage of PET film after copolymerization modification can be as high as 70%.
The characteristics of heat shrinkable polyester film: it is stable at room temperature, shrinks when heated (above the glass transition temperature), and thermal shrinkage of more than 70% occurs in one direction.
The advantages of heat shrinkable polyester film packaging are:
Close-fitting and transparent, reflecting the image of the product. Tighten the packaging, good anti-scattering property. Protected against rain, moisture, and mildew. There is no recovery, and there is a certain anti-counterfeiting function. Heat shrinkable polyester film is commonly used in the convenience food, beverage market, electronic appliances, metal products, especially shrink label is its main application field. Because with the rapid development of PET beverage bottles, beverage bottles such as Coke, Sprite, and various fruit juices require PET heat-shrinkable films to be matched with them for heat sealing labels. They are both polyesters and are environmentally friendly materials, which are easy to recycle and recycle. use.
In addition to being used as shrink labels, heat-shrinkable polyester films have also begun to be used in the packaging of daily commodities. Because it can protect the packaging items from impact, rain, moisture, and rust, and it can make the products win users with beautifully printed outer packaging, and it can well display the good image of the manufacturer.
More and more packaging manufacturers use printed shrink film to replace the traditional transparent film. Because the printed shrink film can improve the appearance of the product, it is conducive to the advertising of the product, and it can make the brand of the brand produce a deep impression in the minds of consumers.
Exceptions can also be used: polyester film for packaging, polyester film for bronzing, polyester film for holography, polyester film for holographic laser anti-counterfeiting trademarks, polyester film for capacitors, black polyester film, polyester matt film , PET polyester twisted film.
