Why more and more food companies using PET as the main packaging material?

April 25, 2023

        In recent years, the food industry has witnessed a significant shift in packaging materials. One material that has become a popular choice for food companies is PET. PET (Polyethylene Terephthalate) is a very common type of plastic material used for food packaging. PET materials are widely used in the food industry for their durability, safety, and recyclability. But what makes PET such an appealing option for food companies? In this blog, we will explore the various reasons behind the increasing adoption of PET as the main packaging material in the food industry.

        The main advantage of using PET materials for food packaging is their exceptional resistance to moisture, oxygen, and gas. As a result, they provide excellent protection to the food products, and they also preserve the freshness, flavor, and quality of the food. Moreover, PET materials are transparent, which allows consumers to see the contents of the package before buying, they are more likely to choose products with clear, visually appealing packaging, so that may help to increase sales.


        PET is an economical option for food companies as it provides a combination of excellent properties at a relatively low cost. Its lightweight nature means reduced shipping costs and resource efficiency during production. The cost-effectiveness of PET packaging ultimately increases profitability for food companies without compromising on quality, hygiene, and sustainability.


        PET offers impressive barrier properties that make it an ideal choice for food packaging. It effectively protects the contents from oxygen, moisture, and odors, ensuring the food remains fresh for an extended period. So PET materials are safe for food packaging because they are non-toxic and do not contain harmful chemicals. PET is approved by the FDA and other regulatory bodies around the world for use in food packaging. In addition, PET materials are resistant to bacteria and other microorganisms, which helps to keep the food safe for consumption.

        PET materials are also recyclable, which is an important factor in the food industry. Recycling PET helps to reduce waste and lower the amount of plastic that ends up in landfills or in the environment. PET can be recycled into a variety of products, including clothing, carpeting, and other types of packaging.


        However, there are some concerns about the use of PET materials for food packaging. For example, there are concerns about the potential for the release of antimony from PET bottles into the food or beverage they contain. Antimony is a toxic material that can cause health problems. However, research has shown that the levels of antimony in PET bottles are low and do not pose a significant risk to human health.


        With its numerous advantages, it comes as no surprise that PET is becoming the preferred packaging material in the food industry. In conclusion, PET materials are widely used in the food industry for their durability, safety, and recyclability. They provide excellent protection to the food products and preserve their freshness and quality. PET materials are safe and non-toxic, and they are approved by regulatory bodies around the world. Recycling PET helps to reduce waste and lower the amount of plastic that ends up in the environment. Overall, PET materials are an excellent choice for food packaging.
