EPDM rubber is a terpolymer produced by epdm extruders using ethylene, propylene and non-conjugated diene as raw materials. Commercial production began in 1963. Annual consumption worldwide is 800,000 tons. The main feature of EPDM is its superior resistance to oxidation, ozone and erosion. Since EPDM rubber belongs to the polyolefin family, it has excellent vulcanization properties. Among all rubbers, EPDM has the lowest specific gravity. It can absorb a large amount of fillers and oils without affecting the characteristics. Therefore, a low-cost rubber compound can be produced.
Molecular structure and properties
Tripropylene is a terpolymer of ethylene, propylene, and a non-conjugated diene. Diene has a special structure, and only one of the two bonds can be copolymerized. The unsaturated double bond is mainly used as a crosslink. The other unsaturated one will not become the polymer backbone, but only the side chains. The main polymer chains of EPDM are fully saturated....  أقل

Product labels should include product logos, manufacturing dates, product descriptions, and graphic designs. Labels must not only differentiate between products, but also have attractive patterns and fonts to promote sales.
The need for product labels:
The manufacturer must design a label for the product. It may be just a simple label attached to the product, or it may be a well-designed pattern that integrates with the product packaging. Some in mould labels only indicate the brand name, and some are quite rich in content. Although manufacturers prefer simple labels, sometimes the law requires the labels to provide more information.
Features of product tags:
Tags have several functions, so manufacturers have to decide what features their tags should have. The minimum function of a label is to identify a product or brand, such as the Sunkist stamp on a Shangi Citrus. Labels can also be...  أقل

Depending on the nature of the product, different printing methods are selected. For different printing methods, the platemaking process is also different. This article briefly introduces the flexible plate making process as an example.
The process of flexographic plate-making is as follows: manuscript-film (exposed film) -exposure-rinsing-drying-post-processing.
1. Original. The manuscript design suitable for flexible printing should have the following characteristics: many color numbers. However, there are few in mould labels; it is not required to reproduce particularly small details; the network cable is not too high, but it can obtain color printing effects; it can be used for packaging processing online.
2. Film (overcast). It meets the needs of plate making, with clear graphics and accurate size specifications; using frosted film, the density of the four corners of the film must be consistent; using the film orthography;...  أقل
