1. Food-grade issues have always been TPE focus topic in the industry, this issue has been in the past 5 years, has been concerned by the industry, and user inquiries also confirm the potential demand for food-grade TPE 's potential demand and TPE passing relevant food-grade tests' difficulty. In this article, Juye Plastic TPE combined with TPE industry 12 years of understanding and insight, comprehensively discusses the issue of TPE food-grade, hoping to be helpful to buyers. The TPE discussed in this article is a material based on SBC styrenic elastomer blending modification.TPE,TPRmaterials' transparency,depends on the selection of components in the compounding system.
,As long as the appropriateSEBS、SBS base materials, suitable plastics(such asPP,PS) grades, without adding fillers, color powders, flame retardants, and other functional additives, it is possible to blend and synthesize transparentTPE、TPR pellets. However, differences in the specific brand and specification selection of each component material in the compounding system, differences in the ratios of each component, will affect the transparency of theTPE、TPR materials.

2. Different food-grade testing standards for TPE
First, different countries or regions, have different industry standards for food-grade testing, secondly, for different types of food contact materials, there are different testing methods. For example, the EU's food contact material testing standard isEC/1935/2004, and within EU member states, some countries even have their own specific testing standards, such as Germany's food-grade testing standard isLFGB. France's isFrench DGCC RF 2004-64. As for the United States, it is byFDAInstitutions establish food-grade testing items and standards for corresponding materials.

3. TPE materials/products food-grade testing standard confirmation
The general principle is to determine the food-grade testing standards that comply with the region according to the export region of the product.. If the product is exported to the United States, the general framework naturally must comply withFDA food-grade testing standards, exported to the European Union, naturally must comply withEC/1935/2004. Sometimes, for different products, the exporting countries are different, the specific testing items may vary. For example, the EU general food-grade contact materialTPE testing standard, for migration testing, mainly tests water, alcohol, and acid (distilled water, 50% alcohol, 3% acetic acid, different materials tested, the concentrations of solvents may vary), but Germany'sLFGB, in addition to water, alcohol, and acid testing, there is also oil(olive oil) testing item.

Another example is the US FDA food-grade testing standard.For TPE, the 21CFR177.2600 testing standard is adopted.In principle, both distilled water and n-hexane tests should be performed.But the standard also states that the n-hexane test is mainly for TPE materials and products that contact fatty foods.In fact, many times,, the user's TPE products may only come into contact with some non-oily, packaged foods, and do not need to undergo the n-hexane test.But end customers require FDA test report, which for a period left TPE material and product suppliers in the industry in a dilemma.Now, some TPE suppliers and users, when making TPE products that do not need to contact fatty oily foods, only test distilled water, and do not perform the n-hexane test

2）Alcohol and acid test
Mainly refers to ethanol(alcohol) and acetic acid test,Probably different countries or regions have slightly different test standards,the selected solvents and concentrations vary,but the test purpose is the same.Shanjin believes that this is mainly for some beverage packagingTPE products.To pass this item,the difficulty is very high,TPEthe selection of compounding materials is very important,during the product processing, attention should also be paid to equipment cleaning and the introduction of additional substances.Of course, if the compounding system is appropriate,there are still a fewTPE that can pass the alcohol and acid dissolution test.

3）Oil test
Mainly refers to olive oil(for GermanyLFGB) and n-hexane(for the United StatesFDA and other test standards using this solvent,such as Chinese national standardGB).These two types of oily solvent dissolution tests,TPE,TPR almost cannot pass the test(Some senior industry professionals believe that the n-hexane test is more stringent than the olive oil test,More difficult).It is said that a few foreignTPE companies' materials, hardness60~70A above, have TPE grades that can pass the olive oil and n-hexane testsTPE grades, but whether it is specificallySBC-basedTPE,Shanjin has not verified.
In addition to the above two oily solvents, some other countries' food grade testing standards, the solvents used for migration tests, include heptane, or isooctane, etc..
