In our daily lives, we are often exposed to various plastic products, especially when it comes to food packaging and food containers. However, regarding the two materials, TPE and PVC, do you know whether they are suitable for use as food-grade materials?Today, we're going to dive into the properties of TPE and PVC and answer which material is better for food-grade applications.
First, let's take a look at the basic concepts of TPE and PVC. TPE is an abbreviation for Thermoplastic Elastomer, which is a material that is elastic and malleable and can be repeatedly heated and cooled without losing its properties. PVC is the abbreviation of polyvinyl chloride, which is a common plastic material with good weather resistance and chemical resistance.
Regarding food safety, there are some differences between TPE and PVC. TPE materials are generally considered to be relatively safe food grade materials. It is free of harmful substances such as halogens and heavy metals and meets relevant food safety standards. In addition, TPE has good high temperature resistance and can withstand high temperature hot water cleaning, so it is suitable for making food containers, sealing gaskets, etc.
In contrast, PVC materials have some controversy when it comes into contact with food. While PVC is widely used in food packaging and food containers, it can release harmful substances such as phthalates, a plasticizer, during its manufacturing. These plasticizers can pose a potential risk to human health, especially in the case of long-term contact with food. Therefore, for direct food contact, it is recommended to choose other safer materials instead of PVC.
In addition to food safety, TPE and PVC differ in other ways. TPE material has good softness and elasticity, which can simulate the touch of the world, so it has been widely used in the production of baby bottles, latex nipples, etc. PVC materials are more commonly used in rigid plastic products, such as pipes, wire insulation, etc.
In conclusion, TPE material is more suitable for use as a food-grade material than PVC. It does not contain harmful substances, has good high temperature resistance and a soft touch. While PVC materials have some potential health risks in terms of food contact, they need to be used with caution.
When we choose to buy food packaging or food containers, it is important to understand the properties of the materials. We should choose materials that meet food safety standards to ensure the quality and safety of food. In the future, we also look forward to the emergence of more safe and environmentally friendly alternative materials to bring more convenience and health to our lives.
Hopefully, through this article, you have a clearer understanding of the food-grade applications of both TPE and PVC.
