vPET for food packaging

Virgin PET (vPET) is produced from oil or renewable resource based monomers. The POLYMETRIX solid state polycondensation (SSP) technology is the last step in the manufacturing chain and upgrades the PET to fulfill the demanding quality and food safety requirements for food packaging applications.

vPET pellets manufactured with POLYMETRIX SSP process technology are converted to PET bottles for all major beverage brand owners. The purity of the material complies with all national and regional food packaging regulations, such as those of the FDA and Efsa.

With the SSP treatment the PET quality is adjusted to meet the specifications for each individual type of bottle. The SSP is designed to accept PET with various co-monomers and co-monomer concentrations. Precise and stable viscosity, low residual content of acetaldehyde, dust and oligomers as well as optimum processing characteristics for injection molding of preforms are key advantages of PET pellets from POLYMETRIX SSP plants.

In addition to the predominant use for food bottles, PET is also used to manufacture food jars, sheet for thermoforming or bottles for non-food applications.

vPET for technical applications

POLYMETRIX SSP process technology is particularly well suited to produce PET pellets with very high viscosity. The high viscosity PET pellets are required for the manufacture of high tenacity yarns, packaging straps and other specialties.

Typical applications for these products range from tire cord to seat belts and conveyor belts as well as hoses, nets and ropes. The material fulfils the most demanding requirements of reputable automotive, tire and special textiles manufacturers. Usually homo-polymer PET with or without pigments like titanium dioxide is used for these applications. 

A high viscosity increase, an even viscosity distribution, minimal dust and oligomer content as well as optimum processing characteristics for subsequent spinning processes are key advantages of PET pellets from POLYMETRIX SSP plants.

rPET for food packaging

POLYMETRIX PET recycling technologies make it possible to convert post-consumer PET bottles into recycled PET (rPET) suitable for direct food contact applications. The rPET pellets are fully compatible with virgin PET and are used for beverage bottles and food trays with up to 100% rPET content.

rPET treated in POLYMETRIX SSP processes fulfills the specific requirements of the packaging industry, the national safety regulations for food packaging and even the strict quality requirements of global beverage brand owners. These high quality standards are achieved regardless of the collection method of the used bottles and regardless of the intended final use of the new bottles or trays.
Precise and stable viscosity, extremely low levels of residual contaminants as well as optimum processing characteristics for injection molding of preforms are key advantages of rPET pellets from POLYMETRIX SSP plants.

All POLYMETRIX recycling processes place the SSP step at the end of the recycling chain to remove degradation products from past heat histories. This is inevitable to maintain the high quality of PET even after multiple recycling loops.

About us

Company details

Bühler Thermal Processes AG is now POLYMETRIX
Bühler Thermal Processes AG in Oberbüren has changed its name to POLYMETRIX at the end of March 2015. Bühler Thermal Processes AG had emerged in July 2013 from the Bühler Group as an independent company. After two years of transition the new POLYMETRIX brand gives the people, products and services of Bühler Thermal Processes AG their unique identity.
Polymer production and recycling plants from one supplier
POLYMETRIX designs, supplies and installs complete industrial plants for the thermal treatment of bulk materials, based on the well-known polymer technologies and services from Bühler Thermal Processes AG. In addition, POLYMETRIX develops and distributes new process technologies, in particular for producing virgin and recycled plastics. As SSP market leader POLYMETRIX is your technology, process and engineering partner for the thermal treatment of polyesters, polyamides and other polymers. The polymers from our plants are used for high value applications like PET bottles, yarns for seatbelts, tires, hot air balloons or high performance sports clothing from PET or PA and optical fibers made of PBT.
Plant design and process consulting
As a renowned technology and engineering company, POLYMETRIX has the proven experience to successfully provide complete manufacturing plants to its customers around the world. POLYMETRIX plants are based on our proprietary process and equipment design. In addition to the process equipment an overall plant design includes storage and handling of raw materials and finished products as well as utility generation and distribution facilities. 
POLYMETRIX provides consulting services in the fields of process optimization and extension or conversion of existing plants, regardless of the original plant supplier. Unique laboratory-scale tests and process simulation models allow our specialists to assess customer specific material and plant characteristics. New plant designs or modifications are always optimized for these specific requirements.
