Today, PET is still widely used in these areas, but since the 1970s, the market needs a light weight, not easily broken bottles to pack gas drinks, pet has become a choice. Unlike PE, a simple polymer, pet is not a single process, but by the purity of terephthalic acid and ethylene glycol, the two chemical reactions to the original. In the past the supply of pet has been designated as the first practical, leading to new production capacity this year to ensure the growing demand for pet in the future. The related polyester also has pen (polyethylene glycol phthalate) and PBT (poly (ethylene terephthalate), this material is mainly referred to engineering plastics. Pen has more performance than pet, especially its performance on barrier properties and heat resistance. Since the use of pen and pet to create a series of alloys, the application of some special packaging is possible.

As a transparent, wear-resistant, corrosion-resistant plastic, pet (bottle-level) with high strength and smoothness, pet bottles are widely used to package mineral water, fruit, edible oil, medicine and cosmetics and so on. 1, melting Temperature: 254-256℃2, crystallization: ≥45%

The crystallization or crystallization of pet products can be made by controlling crystallization temperature and cooling speed. The higher the viscosity, the slower the crystallization rate. The key factors affecting the molding and performance of PET bottles are crystallization and crystallization orientation. If the pet number of sweat is relatively high, in the molding process will occur hydrolysis, viscosity will decline, meaning that product quality is affected.

We have a production process for Plastic Electronic Bag With Zipper.

Pad printing process and screen printing technology has a lot of similarities, for example, the substrate of the adaptability of a wide range of inks, printing inks and screen printing ink basic can be universal, through the replacement of fixture and printing plate can be very convenient to complete the printing of different products. 

So in many occasions, pad printing technology and screen printing technology is inseparable, playing a major role in the special printing, is because of printing technology and screen printing technology so close, most of the printing experts to the screen printing field to study, so far, there is no specialized agency to study the technology of pad printing, and there is also a lack of institutions specialized in the detailed investigation of the distribution of the printing technology in the market, and many of the data of the printing enterprises cannot independently reflect the actual situation of the printing technology.
