【 Yipu New Materials 】 Food grade Polyester Safety Upgrade and Industry Observation Series

The safety and quality of plastic beverage bottles and food packaging that we come into contact with every day have always been the focus of attention for both the industry and consumers.

Starting from the mandatory national standards for food contact materials, let's learn about this content togetherPETAntimony (Sb) is a key element in the polyester industry that is well-known but overlooked by the public.

　　The industrial 'unknown hero' hidden in daily packaging

In PET polyester (food grade)plastic bottlecoreraw material）In the decades of rapid industrial development, antimony based catalysts have always been an indispensable and important technological solution.

As an efficient polycondensation catalyst in polyester synthesis, it is cost-effective and catalytically stable, supporting the large-scale development of the global beverage packaging and food container industries. The modern and convenient bottled beverage consumption market cannot do without the long-term support of this mature technology.

It is an industrial hero that promotes the scale of the PET industry chain and provides important support for the popularization of food packaging.

　　Industry Focus: Regulatory Upgrades Drive Continuous Improvement of Safety Standards

In recent years, China's GB 4806 mandatory standard for plastic materials and products in contact with food and the EU 10/2011 regulation on food contact materials have been continuously updated, which has put forward more comprehensive and strict control requirements for the safety of food contact materials.

Antimony element, as a catalytic component used in the industry for a long time, has a widely studied material characteristic:

In processing scenarios such as acidic environments, high-temperature filling, and high-temperature sterilization, there is a possibility of trace migration of antimony components from polyester chips and bottle walls to the contents.

At present, the migration volume of compliant products in the market meets the national mandatory standard limit requirements, which can meet the safety standards of conventional usage scenarios.

With the increasing demand for healthy consumption and high-end food scenarios, the industry continues to pay more attention to raw material solutions that are free of heavy metals at the source, have lower residues, and are safer in the long term.

　　Our viewpoint:

Compliance is the bottom line, safety is traceable

In the field of PET polyester and food packaging safety, we always adhere to:

Compliance with national standards is the fundamental bottom line for product entry into the market and a common principle followed by the industry.

Facing scenarios with higher purity requirements such as high-end food, drinking water, and baby products, the industry is upgrading towards safer sources, more controllable ingredients, and no heavy metal intervention.

By using a heavy metal free catalytic system in the polyester chip synthesis process, the risk of residual components can be further reduced, making food contact materials more suitable for high-quality and long-term safe consumer needs from the source.

This is not only a choice for food enterprises to upgrade their quality, but also an important direction for the development of the industry chain towards safer and more environmentally friendly directions.
