Always not ideal, does anyone know?

overview

1, about 150 degrees ; In addition to the temperature, it also depends on the quality of plastic packaging paper. Some paper is of good quality and relatively resistant to high temperature. There is no problem at about 150 degrees. If it is low, it can’t be sealed

2. There are two plastic sealing methods: thermoplastic and cold plastic. Thermoplastics uses multi-stage temperature control and rolling heating to produce high temperature to finalize the plastic sealing film and data page. Cold plastic is to use plastic film with viscosity or magnetism to shape the plastic film and data page without heating

3. When plastic sealing the data page, first separate the plastic sealing film, clamp the data page in the middle, make the gluing surface of the plastic sealing film face the data page, then close the plastic sealing film, feed it into the plastic sealing machine from front to back for heating, and then come out of the rear discharge port after being pressed by the front and rear rubber rollers, so as to achieve the purpose of plastic sealing

4. Cold mounting is to use cold mounting technology to cover a layer of cold mounting film on pictures and photos. Smaller photos or pictures can be mounted by hand. If the object to be coated is large, you need to use a cold mounting machine. Cold mounting film is made of transparent PVC through back glue processing. According to the texture of the film surface, it can be divided into light film, dumb film and special texture protective film. Light film and dumb film are widely used in advertising production

5. The cold mounting film is mounted on the photo printed picture with cold mounting machine and other equipment to prevent the picture (printing surface) from being scratched, polluted or wet, so as to protect the picture

about 150 degrees. In addition to the temperature, it also depends on the quality of plastic packaging paper. Some paper is of good quality and relatively resistant to high temperature. There is no problem at about 150 degrees. If it is low, it can’t be sealed. Some paper is relatively cheap and poor quality, 130 degrees to 135 degrees. It is recommended to test one or two at the beginning, depending on the situation

the difference between superplasticization and plastic packaging:

I. different working principles:

1. Superplasticization is to place the articles (documents, pictures, etc.) to be plastic encapsulated in the middle of the plastic packaging film and press them with the high and mild pressure of the machine rubber roller

2. Plastic packaging is divided into thermoplastics and cold plastics. The method is as follows:

(1) thermoplastics: when plastic packaging the data page, first separate the plastic packaging film and clamp the data page in the middle so that the gluing surface of the plastic packaging film faces the data page. Then close the plastic packaging film and send it into the plastic packaging machine from front to back for heating. After being pressed by the front and rear rubber rollers, it comes out of the rear discharge port, So as to achieve the purpose of plastic sealing

(2) cold mounting is to use cold mounting technology to cover a layer of cold mounting film on pictures and photos

II: different uses

overmolding is generally used to protect articles from deterioration and damage, such as overmolding photos. Plastic packaging mostly refers to the packaging of products, which is a kind of packaging method. Many of our common small commodities are packaged in plastic

III: the machines used are different

superplasticization generally uses small heating devices, accounting for a small area. The plastic sealing machine has a large volume and complex structure, which should be operated by professional personnel. The common plastic sealing machine is high-frequency thermoplastics machine

about 150 degrees
in addition to the temperature, the quality of plastic packaging paper also depends on. Some paper is of good quality and relatively resistant to high temperature. There is no problem at about 150 degrees. If it is low, it can’t be sealed. Some paper is relatively cheap and poor quality, 130 degrees to 135 degrees. It is recommended to test one or two at the beginning, depending on the situation.

in addition to the temperature, the quality of plastic wrapping paper also depends. Some paper is of good quality and relatively resistant to high temperature. There is no problem at about 150 degrees. If it is low, it can’t be sealed. Some paper is relatively cheap and poor quality, 130 degrees to 135 degrees. It is recommended to test one or two at the beginning, depending on the situation.

see what you’re going to plastic wrap? I think it’s easy to grasp. I’m talking about a simpler plastic sealing machine. If it’s not sealed, adjust it to the high point, and if it’s burnt, adjust it to the low point.
