Things to Know When Choosing Safe Food Bags (Part 1)

Food is an essential need of each of us. From supermarkets, markets, to food stores, food bags are widely used to preserve and transport food. However, few people realize that, besides convenience, unsafe food bags can pose many risks to human health. To clarify the potential risks, and at the same time provide the necessary knowledge for consumers to choose safe food bags and protect their own health. Tashing will help you learn about the potential risks from food bags and how to choose safe bags.

Potential risks from using unsafe food bags

Toxic chemicals enter food

How chemicals can enter food through plastic bags

Packaging plays an important role in preserving and transporting food. However, packaging that does not meet food safety standards can pose many potential risks to consumers’ health because harmful substances can enter food through the following routes:

• Direct migration:
  – Chemicals from packaging materials. Some types of packaging are made from materials containing toxic chemicals such as BPA, phthalate, heavy metals, etc. When in direct contact with food, especially at high temperatures or acidic conditions, these chemicals can migrate into food. And this causes many harmful effects on health such as cancer, endocrine disorders, effects on the nervous system, etc.
  – Microorganisms from contaminated packaging. Packaging that is not cleaned or stored properly can become a breeding ground for harmful microorganisms such as bacteria, mold, etc. When in contact with food, these microorganisms can cause food poisoning, diarrhea, vomiting, etc.
• Chemical reactions:
  – Interaction between food and packaging. Some types of Highly acidic foods such as orange juice, tomatoes, etc. can react with the ingredients in the packaging, releasing toxic substances.
  – Packaging degradation. Plastic packaging, especially when exposed to high temperatures, can degrade and release microplastics. Microplastics can accumulate in the body and cause many harmful effects on health.

Toxic chemicals that can enter food

Here are some toxic chemicals commonly found in poor quality packaging and the risks associated with them:

• Bisphenol A (BPA) and Phthalates: BPA and Phthalates are two chemicals commonly used to make plastics softer and more flexible. They are present in polycarbonate plastics (such as water bottles) and in plastic softeners. BPA has been known to affect the endocrine system and can lead to health problems such as hormone disruption and increased risk of cancer. Phthalates are also a concern and may affect reproductive health.
• Preservatives: Preservatives such as BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene) are often added to packaging to prevent oxidation and deterioration of foods. However, when exposed to food, these substances can cause health problems such as allergies and may be carcinogenic in some cases.
• Thickeners and Colorants: Some food packaging may contain thickeners such as Titanium dioxide (TiO2), which is used to white or color products. TiO2 has been linked to cancer risks with long-term exposure. Colorants such as Tartrazine may also cause allergies or other health problems in sensitive individuals.
• Anti-stick chemicals: Some food packaging, such as candy bags or bread wrappers, is coated with anti-stick compounds such as Perfluorooctanoic acid (PFOA). These substances, when in contact with food, can cause health problems such as hormone disruption and cancer.
• Heavy metals: Lead and mercury are two heavy metals commonly found in packaging, especially in recycled packaging. They can lead to serious health problems such as memory loss, behavioral disorders and nervous system effects.

Improper use of bags

Using expired bags

Food bags have an expiration date and using them after the expiration date can cause many problems. When the bag has expired, the quality of the material may deteriorate, leading to a decrease in the ability to preserve food. Furthermore, using expired bags can also reduce the durability of the bag, leading to the risk of leakage and contamination. This not only affects the quality of the food but can also be harmful to health because toxic substances can be released from the bag into the food.

Using the wrong type of bag

Using the wrong type of bag for the type of food is also a common mistake. Each type of plastic bag is designed to serve a specific purpose and has different physical and chemical properties. Using the wrong bag can lead to leakage, reduce the bag’s ability to prevent water and gas penetration. This causes unhygienic conditions and affecting the quality of the food inside. Furthermore, unsuitable plastic bags can also increase the risk of bacterial contamination by not ensuring a safe storage environment for food

Using bags to heat or cook food

Another common mistake is using plastic bags to heat or cook food in a microwave or pot. Plastic bags are not designed to withstand high temperatures. And people use them in cooking processes can lead to food safety issues. The materials in plastic bags can undergo chemical reactions when exposed to high temperatures. This leads to the release of toxic substances into food. This can be harmful to health if food is exposed to unsafe compounds from plastic bags.
