New material PET plastic packaging bottle
Since the emergence of new material, PET plastic bottles have been replacing PE in various industries, but it has been in dire straits with acrylic. It can be said that: continuous development and breakthrough in the crisis, no one can guess the prospect, we just need to remember sustainable development and stability in the pursuit of success. PET is hollow, injection stretch blow molding, non-toxic, tasteless; of course, there are often some problems in the process of use. Let us explain injection stretch blow molding first;
First, the embryo tube needs to be obtained. The embryo tube is formed by an injection molding machine, then the hot parison is stretched, and then it is stretched horizontally by compressed air to obtain a product with the same shape as the mold;
A high-quality product is really troublesome, and it is necessary to control the temperature is too high, the pressure is too high, the heat seal design is too long, the silicone rubber on the bottom seal is too hard, etc., otherwise it will cause brittleness on the teeth or the seal; if you ask, my solution is definitely to avoid these, it’s all technical and professional;
Its melting temperature is 256~280°C, the pressure is 300~1300bar, and the drying conditions are about 120~165°C. Seeing this data, the editor is thinking wow, it is estimated that it can’t be eaten by living things, haha; PET can be made of material. In solid color and transparent products, depending on your needs and ideas;
With the gradual maturity of plastic packaging bottles, the market competition is becoming more and more fierce, but continuous innovation is required. In order to meet the needs of the market, we must continue to have our own innovations, strengthen efficiency, and keep up with market development and changes.
