PET can be completely recycled and used

PET (resin) good stability

PET shows the best chemical stability in all the main polymers used for packaging.

Long shelf life

Very good shelf life performance, especially the new high barrier form.

Choose the right grade of resin to meet different packaging needs.

Although all grades are feasible, only one result from all walks of life tends to meet his needs.

In fact, PET is used in a wide variety of packaging, from soft drinks to cosmetics. However, the quality of the resin must meet the standards to protect the safety of products and distribution. Not only does the product need to maintain a good storage environment, it also has to be sold. In this case, the beverage food and its packaging must be attractive, sensible and convenient. The choice of resin for a certain PET application must meet the needs of the end product. Strength, transparency, barrier properties, and UV resistance are a few of the factors that are considered for packaging.

Both homopolymers and copolymers are applied to PET resins. In the PET homopolymer, only repeat units of terephthalic acid and ethylene glycol give the PET its highest melting point and best strength properties. The copolymer PET contains other monomers, such as isopeptide acids, which disturb the polymeric chains, lower the melting point, slow down crystallization, and increase transparency especially in thickness applications.

Different grades of resin are suitable for different end uses. These special features can create the ideal product in their design packaging. Which features of PET are the most important? According to the above, the characteristics of the most important ones are determined by the bottles that are packaged and packaged.

PET recycling

PET can be recycled completely, and it is convenient. Its recycling code is 1, and post-consumer recycled PET (PRC PET) can be used to make clothes and carpet fibers, or it can be used to make fibers, for example as a filler for pillows. Recycled PET can be used for non-food bottles, such as cleaning products. Containers for the manufacture of food and beverages do not have recycled PET. It must go through an approved process to ensure that there are no contaminants, and must retain sufficient raw properties to meet the final quality requirements.

A simple and popular method is to simply break the PET formed product and then mix the broken PET particles into the new PET resin, but the mixing ratio cannot exceed 20%. The high repolishing ratio will make the melt viscosity, color, and odor different. When using recycled materials, magnetic hoppers are recommended for injection molding machines.
