PPSU Materials In Food Containers Application

May 16, 2024

What exactly are the outstanding advantages of PPSU raw materials in food containers?

With the development of society, we live in the plastic material tableware, etc. are in contact with food materials, such as packaging materials, containers, detergents, disinfectants and food production and management of tools and equipment. Due to the direct contact with food, the chemical components of food contact materials may be directly transferred to food or have chemical reactions with food components, which may even cause food quality degradation or food safety problems. However, in fact, in daily life, people generally pay little attention to the safety of food contact materials, including food containers.

In fact, the harmful substances in food contact materials mainly include bisphenol A, plasticizers, formaldehyde and melamine, volatile organic compounds, heavy metals and so on, which are potentially toxic in terms of carcinogenicity, teratogenicity and mutagenicity, and can trigger systemic dysfunction, especially affecting the development of the nervous system of newborn children.

With the rapid development of polymer materials and the demand for "lightweight" use, plastic food containers are being more and more widely developed and applied, and there is an endless supply of food-grade materials. When commenting on the safety of a new material from the consumer's point of view, in addition to considering the structure and properties of the material itself, it should also be fully integrated with its use in food applications, and its impact on food safety should be evaluated on the basis of the amount of migration. Below we understand what exactly are the advantages of PPSU raw materials in food containers?

First, PPSU raw materials are reliable food contact materials

1. The material itself has superior performance

PPSU commonly known as Polyphenylsulfone, is a sulfone polymer, belongs to the special engineering plastics, high temperature plastics. With excellent physical and chemical properties, in the field of health care, automotive, aviation, electrical and electronic, etc., can replace thermoset plastics, metals and ceramics, through injection molding, extrusion, blow molding, machining, etc. processed into high-quality parts and high load capacity products.

It is worth noting that the PPSU resin itself is non-toxic and does not release Bisphenol A. Being a food-accessible material is very friendly to babies and children, and in recent years, this has become a reassuring material for the manufacture of baby bottles in the global maternal and child fields.

Second, PPSU raw materials in food containers on the advantages of performance

In the field of food containers, PPSU material can be used to replace glass, metal ceramic and thermosetting materials. Compared with other types of resin, PPSU material tableware performance is very excellent.

1, more temperature-resistant: temperature resistance of 180 ℃, can fully meet the needs of daily use of the family and with the harsh use of the environment, and will not release bisphenol A and other substances.

2, microwaveable: can be fully applicable to the use of microwave environment.

3, more resistant to steam sterilization: can withstand high-temperature steam sterilization / cleaning cycle, suitable for sterilizers, dishwashers, and the performance remains unchanged.

4, recyclable, repeated use: can be repeatedly used and recycled, in place of disposable tableware has a certain space, conducive to saving resources, environmental protection.

5, good chemical resistance, no residue: in the corrosive detergents and disinfectants, water and extreme heat conditions, will not be affected by the joint action, no residue, will not adsorb food odors and stains, easy to clean.

6, flame retardant: PPSU resin flame retardant, in the event of a fire almost no release of heat and any harmful substances, has been applied to airline lunch boxes.

7, drop-resistant: shatter-resistant is child-friendly, such as the current application of PPSU milk bottle cases.

8, light weight: compared with traditional food containers, the material is lighter, easy to use.

9, transparent material: transparent material without adding any substances, easy to increase the user's visual experience.

As a food contact material, PPSU raw materials, compared with other types of resins, comply with China, the European Union and the U.S. FDA regulations on food contact materials, and in recent years in the field of food containers outstanding performance advantages.
