"Polyethylene itself is non-toxic. Polyethylene is mainly divided into high-density polyethylene, low-density polyethylene and linear low-density polyethylene. The surface of polyethylene is dull, milky white waxy granular, corrosion-resistant , the water absorption is relatively small, and the electrical insulation is relatively high. It is mainly divided into two production processes: high-pressure tube method and kettle type. It is mainly used for agricultural film and industrial packaging film products."

The biggest difference between digital printing and traditional printing

The biggest difference between digital printing and traditional printing is that it saves the process of producing film and printing PS version, and directly completes the printing process from computer to paper. Its imaging principle is also different from offset printing. It is suitable for small batches, personalized prints. As few as a few, as many as a hundred. If you want to have several books that belong to you, such as souvenir albums, travel notes, photo albums, etc., digital printing is the most economical and ideal method. The working principle of the digital printing machine is that the charger charges a layer of electric charge on the surface of the recording drum, and the dot matrix information of the content (such as characters) to be printed by the printer controller is reflected on the surface of the charged recording drum in the form of a laser beam, so as to put When the recording drum rotates to the toner cartridge, the electric charge in the position where there are printing dots will attract the toner. When the recording drum with the toner shape is rotated to the rotating When the printing device is placed, the printing paper is between the recording drum and the transfer device, and the stronger reverse charge added to the transfer device will attract the toner with the font on the recording drum to the printing paper, and the heating part will The toner on the paper will be coagulated and dried, and the fonts on the printing paper will be kept firmly, and the printing process will be ended. There are three printing scales for digital printing: A4 (297mm×210mm), A3 (420mm×297mm) and SRA3 (450mm×320mm). Digital printing is suitable for printing paper with a thickness between 80g and 250g. Digital printing is suitable for a variety of documents, in addition to professional manufacturing software, work software and even print drafts can be used. Of course, the most standard is to provide electronic files in PDF format, which will make the printing process convenient and accurate. Digital printing can do: immediate waiting, copies are abnormal.

What is the difference between "pvc" and "pe"?

1. Application Polyethylene (PE) applications: plastic wrap, vest-style plastic bags, plastic food bags, pails, water bottles, etc. Polyvinyl chloride (PVC) applications: plastic wrap, plastic shoes and leather products, films, cables, plastic bags. 2. Features Polyethylene (PE) has a waxy texture to the touch, is lighter in weight and has a certain degree of transparency compared to the same plastic. Polyvinyl chloride (PVC) characteristics: hard plastic, commonly used in industrial fields.

The difference between PVC material and PE material, and the use of each material

1. Differences in application; Polyethylene (PE) applications: plastic wrap, vest-style plastic bags, plastic food bags, pails, water bottles, etc. Polyvinyl chloride (PVC) applications: plastic wrap, plastic shoes and leather products, films, cables, plastic bags. 2. Different characteristics; Polyethylene (PE) has a waxy texture to the touch, is lighter in weight and has a certain degree of transparency compared to the same plastic. Polyvinyl chloride (PVC) characteristics: hard plastic, commonly used in industrial fields. 3. Differences in material properties; Polyethylene, referred to as PE. It is a polymer of ethylene and is non-toxic. Easy to color, good chemical stability, cold resistance, radiation resistance, good electrical insulation. It is suitable for packaging materials for food and medicine, making tableware, medical equipment, and insulating materials for the electronic industry. Polyvinyl chloride, referred to as PVC. It is a polymer of vinyl chloride. Polyvinyl chloride (PVC) is a synthetic material with many advantages and is an ideal material for engineering plastics. Good chemical stability, acid and alkali resistance. Moisture resistance, aging resistance, flame retardant.
