High Quality Detergent Packing Machine Supplier

PET film and PET release film are commonly used materials in electronics, adhesives, die-cutting, packaging and other industries. However, because of the different industry fields, the names of various thicknesses on the market are different, and the differences in units also lead to various specifications. The name is easy to be confused. Here are examples of the usual thickness of PET film. If you want to distinguish the thickness, you must first fully understand the thickness unit of PET film and PET release film. Commonly used units on the market are as follows: 1mmu003d100c (silk)u003d1000um. Among them, the unit c (silk) is not a national standard unit, and is more common in the hardware machinery industry. There are also individual companies that use 'bars' as the unit, 1 bar u003d 1c. The usual thickness of PET film has the following specifications: 0.012mm, 0.025mm, 0.036mm, 0.05mm, 0.075mm, 0.1mm, 0.125mm, 0.15mm, 0.175mm, 0.188mm, 0.25mm. The thickness of the PET release film is actually divided according to the thickness of the PET film, so when you order or consult, you must also clarify your usual units. Some companies are accustomed to mm, some companies are accustomed to c, and some Use microns. The most common mistake is to make a mistake in ordering 0.025mm and 0.25mm, 0.025mmu003d2.5cu003d25um, 0.25mmu003d25cu003d250um. I believe that many companies have encountered this situation, saying that it is 25 thickness and the samples they receive are far from their own. In fact, this is just a unit difference. It is a company specializing in the production of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, supply of PET motor film, etc. With a wide range of products, affordable prices, and environmental protection, we provide customers with excellent quality and service based on the service tenet of excellence in production, honesty and trustworthiness in distribution, warm and thoughtful service, and the spirit of assisting partners to achieve their own careers.

In recent years, the rapid development of the middle and downstream industries of electronic communication, digital and other adhesive products and protective films will drive a new round of huge demand in the adhesive and protective film industries. From the perspective of industry products and exhibited products at the PET exhibition, most of the tape companies are transforming from ordinary tapes to industrial tapes, while film companies are developing from ordinary PE protective films to high-end films or optical films. This is exactly what the development of the electronics industry has played. Leading role. Now there are two kinds of protective films on the market, PET protective film and PE protective film. Let’s talk about the difference between these two protective films? 　 　 Let’s talk about PET protective film first. 　　 PET protective film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration and other fields. Can be produced into mobile phone LCD protective film, LCD TV protective film, mobile phone buttons, etc. PET protective film has excellent mechanical properties, its strength and toughness are the best among all thermoplastics, and its tensile strength and impact strength are much higher than ordinary films; 　　 After introducing PET protective film, let’s talk about PE protective film PE protection The film is based on a special polyethylene (PE) plastic film, and is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to the density. PE protective film is the simplest polymer organic compound and the most widely used polymer material in the world today. Its biggest advantage is that the protected product is not polluted, corroded, scratched during production, processing, transportation, storage and use, and protects the original smooth and shiny surface, thereby improving the quality of the product and the market competitiveness.　　 PE protective film is a kind of packaging film with more comprehensive performance. It has good transparency and luster; it has good air tightness and fragrance retention; it has medium moisture resistance, and its moisture permeability decreases at low temperatures. PE protective film is a simple polymer organic compound, a polymer material widely used in the world today. PE protective film uses special polyethylene (PE) plastic film as the base material. According to the density, it is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene.　　 PE protective film use: protect the product from pollution, corrosion, scratches during production, processing, transportation, storage and use, and protect the original smooth and shiny surface, thereby improving product quality and market competitiveness.　　 PE is softer, PET is harder; when picked up and shaken, PE has no noise, PET has noise; PE tensile strength is not as good as PET; PE protective film temperature resistance is generally 60 degrees, while PET protective film can be 120 degrees and above. Therefore, when choosing, choose different material protective films for different products. Therefore, the difference between PET protective film and PE protective film is different in terms of advantages and disadvantages, performance, and application fields.

The coating cost of solvent-based silicone oil is low. For example, oil glue K-50, dry glue 60 grams, the coating amount of solvent-based dry silicone coating is 0.80 grams per square meter, if you use solvent-free dry silicone coating The amount of cloth must be 1.30 grams per square meter. Due to equipment limitations and in order to reduce coating costs, many release coating suppliers have added solvents to solvent-free silicone oils to reduce the content of silicone and reduce the amount of coating. The risk is considerable. Moreover, solvent-free silicone oil is not suitable for oil glue. Silicone oil needs to be volatilized and weathered at a certain temperature, so thermal curing silicone oil is mostly used at present. Of course, many domestic companies have already used UV curing, mainly for film coating. Because the film cannot tolerate the curing temperature, UV curing is generally used, which is a relatively expensive curing method, regardless of equipment investment or processing cost. UV curing is one to two times of thermal curing.
