Since the emergence of new materials, PET plastic bottles, has continued to replace PE in various industries, but it has been in deep water with acrylic. It can be said that: continuous development and breakthroughs in the crisis, the prospects are unknown to anyone, we just need to remember Sustainable development and stability, PET is hollow, injection stretch blow molding, non-toxic and odorless; of course, there are often some problems in the process of use, let's first explain the injection stretch blow molding.
First, the embryo tube is obtained. The embryo tube is formed by an injection molding machine, and then the hot parison is stretched, and then compressed air is used to stretch it laterally to obtain a product with the same shape as the mold.
A high-quality product is really troublesome, and it is necessary to control beer can sealing machine the temperature is too high, the pressure is too high, the heat seal design is too long, the silicone rubber at the bottom seal is too hard, etc., otherwise it will cause the teeth or the seal to be brittle; if You asked me that the solution must be to avoid these. They are all technical and professional.
Its melting temperature is 256~280℃, the pressure is 300~1300bar, and the drying conditions are around 120~165℃. I am thinking about seeing these data. I guess it can’t be eaten if it is replaced by living creatures. Haha; PET can be made of materials. Real color and transparent products, depending on your needs and ideas.
With the gradual maturity of plastic packaging bottles, market competition is becoming more and more fierce, but continuous innovation is needed. In order to meet market demand, we must continue to innovate, strengthen efficiency, and keep up with market development and changes.
