3. Raw materials for producing food bags
3.1. In the world
Most of the raw materials used to produce food bags in the world are polyethylene (PE) plastic. In addition, to create food wrapping films, people also use polyvinyl chloride plastic.
- Polyethylene is a non-toxic plastic, so it is very safe for users.
- Polyvinyl chloride is also a non-toxic plastic, but single molecules of this substance are capable of causing cancer. Therefore, many European countries have announced a ban on the production of food wrap from this material.
3.2. In Viet Nam
In Vietnam, most bags are mainly made from HDPE and LDPE plastic films, a few are made from PP plastic. But the quantity is not significant. In particular, HDPE and LDPE plastic films are both different forms of PE plastic, so they are relatively safe.
However, there are also some facilities that are currently adding some additives to the bag production process to increase the bag’s flexibility and waterproofing ability. These types of bags can lead to dangerous diseases for users.
So, many users have switched to using completely biodegradable bags to both protect their health and be environmentally friendly.
4. Pay attention when choosing to buy and use food bags
There are many food bags sold on the market, but not all bags are safe and suitable for your needs. Here are some things to note when choosing to buy and use these bags you need to know:
You should buy from reputable brands with proven origins and clear evidence of decomposition and environmental friendliness.
When in use, do not use it to store hot food, eggplant salt, melon salt…
Using these bags is essential to help preserve food from spoilage. However, most food bags made from plastic often pose many potential risks of causing disease and environmental pollution. That’s why each family can replace it by using glass containers, plastic containers… and completely biodegradable bags to ensure safety.
