Food packaging is everywhere. It keeps food fresh, protects it during transportation, and helps prevent contamination. But more and more people are starting to think: Is food packaging safe? The answer is yes, it is safe. Most food packaging is safe when used properly. However, in some cases, certain materials may pose some risk.

Understanding the regulations related to food packaging safety, safe food packaging, and cleaning techniques will help us to reduce packaging risks more effectively from the food packaging materials themselves, and the food packaging environment.

1. Food packaging safety regulation

In the United States, the Food and Drug Administration (FDA) is responsible for ensuring the safety of food packaging materials. Before any new material can be used to package food, the manufacturer must submit a detailed safety review through the Food Contact Notification (FCN) process. The review includes toxicology studies, chemical migration testing, and an estimate of the amount of material that may be ingested by humans.

FDA also pays close attention to materials already in use. If new scientific evidence suggests that a material may be harmful, FDA may reevaluate it and restrict or prohibit its use.FDA's packaging safety measures are fully described in this Consumer Overview.

Although FDA's system is very strong, it does not fully address the effects of long-term, low-dose exposures, or the combined effects of multiple chemicals used at the same time.

2. How Chemicals Migrate from Packaging to Food

Even if a material is approved, it may still transfer small amounts of chemicals into food during long-term low-dose exposure to food packaging materials. This is known as chemical migration. This process is so slow and minute that it is not easy to detect, but over time it can lead to a range of potential health risks.

Common "Problem" Packaging Materials and Related Chemicals

Factors affecting migration:

• Exposure time: The longer the exposure time, the greater the migration usually is (e.g., long-term storage).
• Temperature: High temperatures (e.g. heating, direct sunlight, hot filling, microwaving) significantly accelerate migration.
• Nature of Food: High-fat, high-alcohol, acidic foods are more likely to solubilize or promote migration of certain chemicals.
• Type and quality of packaging materials: Different materials and their formulations contain different types and levels of chemicals. Poor quality or non-compliant packaging poses a higher risk.
• Surface condition of packaging materials: Wear and tear, aging may increase migration.

3. Which food packaging materials are safer?

The following materials have a very low risk of migration under the right conditions of use (ambient temperature, non-fatty foods, short-term exposure) and are considered "safe" choices:

Safer options include:

• Plastics labeled with recycling code #1 (PET), #2 (HDPE) or #5 (PP)
• Glass jars, stainless steel containers and ceramic dishes
• BPA- and PFAS-free packaging materials from verified sources

Materials that need to be handled with care include plastics labeled #3 (PVC), #6 (polystyrene), or #7 (mixed types, usually polycarbonate). These materials are more likely to release chemicals, especially when heated or used repeatedly.

When in doubt, switching to glass or stainless steel can significantly reduce the risk. These materials are inert and will not react with food or release harmful substances, even at high temperatures.

4. Is it safe to reuse food packaging?

This is a common question, especially today when more and more people want to reduce waste. The answer depends on the material. Many disposable containers are not designed to be reused. When they are heated or washed repeatedly, they break down and release more chemicals.

Reusable containers made of glass, stainless steel or thick BPA-free plastic are safer. If a container looks scratched, cloudy or warped, it's time to replace it. Even if a plastic container is labeled "microwave safe," it's best to avoid using it for hot, greasy or acidic foods, as these environments can increase chemical migration.

5. How to keep food packaging safe and clean

To keep your video packaging safe, it's best to use food-grade packaging materials and make sure that all packaging materials are approved for direct food contact, however the safety of food packaging doesn't just rely on the choice of materials, the hygiene and safety of the environment is also important. Even the safest materials can become unsafe if not handled or stored properly. This is particularly important in commercial environments, but also applies to the home. Please follow these simple steps:

• Store packaging in a clean, dry place away from strong-smelling chemicals or cleaning products.
• Handle food packaging with clean hands or gloves to avoid introducing bacteria.
• Keep storage areas away from pests, moisture and extreme heat.
• Replace reusable containers that show signs of wear.

Food packaging safety is not only about the packaging materials themselves, but the selection and use of packaging machinery is also critical. Quality packaging machinery not only ensures food sealing and shelf life, but also minimizes the risk of contamination during the packaging process. For example, the use of stainless steel packaging equipment, not only easy to clean and disinfect, but also to avoid the migration of metal ions; and equipped with intelligent detection system of the packaging line, you can automatically identify and reject poor sealing or foreign objects in the product.

Currently on the market advanced packaging machinery has realized the whole process of automation control, from measuring and filling to sealing and packaging are completed in a closed environment, greatly reducing the possibility of human contamination. In particular, some of the food-grade lubricants and GMP-compliant design of packaging equipment, in the pharmaceutical and baby food fields have become standard. These technological innovations not only improve packaging efficiency, but more importantly, add a reliable protective barrier for food safety.

Therefore, when choosing a packaging solution, it is important to pay attention to both the safety of the packaging material and the hygiene standards and technical level of the packaging machinery. Only when the two are perfectly coordinated can the whole chain of safety from production to consumption be truly guaranteed.
