PET bottles are mainly made of materials such as polyethylene or polypropylene and added with various organic solvents. The knowledge of the Pet Preform Manufacturers, you want it all! For PET bottles, there are currently various problems. Let's analyze it carefully. First of all, PET bottles are labor-intensive industries, and the current labor costs are rising. For PET bottle companies, labor costs have become a huge pressure. Secondly, the prices of raw materials continue to rise, and the various costs of the market have risen, and the raw materials have risen sharply, which has caused another pressure on PET bottles. Third, with the European debt crisis and the weakening of the world economy, foreign trade orders for PET bottles have gradually declined, and many foreign trade companies have fought in the domestic market, which has brought greater pressure on the already competitive domestic PET bottle market. The battle is getting more and more powerful, and the profits of enterprises are getting lower and lower. For pet preform manufacturers, under the current pressures, we should take the road of industrial upgrading, take the road of innovation in the field of PET packaging, and strive to increase the added value of PET bottles. Continuous improvement from the design, production and sales of Pet Preform Mould.
