Packaging Materials and Health

After dinner, plastic food boxes, microwave bowls, plastic wrap, fresh-keeping bags, and all the things that could be used to preserve the food were unveiled. Yes, for the health of the family, the rest of the meals must be properly preserved. For a long time, plastic products used in food packaging and storage, including disposable disposable bags, food packaging bags, and plastic containers that can be reused, are all considered safe and harmless. However, the advice from relevant experts is: It is still necessary to carefully understand the constituent materials of the product and master the correct storage method to ensure that there is no threat to your health.
Proposal One: Finding a digital password on the box can make a good choice? A simple and feasible approach is to follow instructions from the manufacturer, which can usually be found in the description section of the original package of the product. If you cannot find the relevant content on the outer packaging of your product, you must think twice before buying it.
If you have a habit of reading the product manual, you will find a lot of useful information in the text at the bottom of the food box. At the bottom of most food boxes there is a triangular number symbol. The entire pattern may also include arrows or other numbers that are used to distinguish product material categories. When purchasing food containers, the following figures deserve our special attention:
Number 3:
Meaning: This number represents PVC. This material has a hard texture and is often used in the manufacture of food containers, pipes, and construction materials. It is widely used in everyday life.
Directions for use: In general, food containers made from this raw material are only suitable for storing dry, low-moisture foods such as rice and pasta. PVC is not very resistant to high temperatures, so food must be transferred to food containers suitable for microwave use before heating food.
Number 6:
Meaning: This is a sign of polystyrene. This material is sometimes foamy and is used primarily for disposable lunch boxes, cups, and cutlery.
Directions for use: In all types of food packaging materials, polystyrene has the lowest melting point, so although it can be used to hold warm foods, do not use this material directly in the food box.
Number 7:
Meaning: This number represents a material other than PVC and polystyrene or a variety of plastic materials. If the raw material of the food box is polycarbonate (including BPA), this figure will appear on the product.
Usage Guide: There are many kinds of materials for food containers. The heat resistance and maintenance methods are also different. Please read the product instructions carefully before use and strictly follow the manufacturer's instructions.
Proposal II: Fully understand the use of lunch boxes to update containers. If you find that the food boxes in your home have been deformed, worn out, penetrated into oil, or have been difficult to clean after a long time, you should make an immediate determination and let them be laid off as soon as possible. Detergents, detergents, and scouring pads can cause abrasion or even corrosion of food containers. The phenomenon of blistering on the surface of the food box indicates that the damage has long been caused. What's more, if the surface is stained by infiltration of vegetable juices, it is likely that the chemical components in the food box are likely to seep into the food in the container during the heating process. Therefore, experts pointed out that we must promptly phase out and replace aging damaged food containers.
Heating instead of boiling - For the use of microwave ovens, the difference between heating and cooking seems to be only one line. However, this difference is very important for the safety of plastic food boxes. Even lunch boxes for microwaves cannot withstand long-term high temperature processing. In general, the food is heated to 60°C. There is a proper safety distance between this temperature and the boiling point. Some materials, such as polycarbonate, will begin to soften and melt around 135°C and therefore cannot be used for food heating. Even other plastic food containers should avoid such high temperatures. The secret to safety is to displace food into a microwave-dedicated container of glass or ceramic material before heating, especially when you plan to use a microwave to cook fresh foods using raw materials, or heat up long-lasting leftovers.
Special bag--when there is no food bag at hand, how about finding a normal plastic bag instead? Don't forget that the U.S. Food and Drug Administration only approved several types of specially treated plastic containers, bags, and convenience bags that can be used to hold foods. Therefore, even if you are in a hurry and urgency, you can't just pick up a few bottles and put your food inside. Even if the instructions indicate that the product is not harmful to the human body, as long as it is not food-specific, taking into account the health of themselves and their families, it must not be used to charge. Expert Tips: Save food, must buy food-specific plastic lunch boxes; foods that need to be kept fresh must be packed in special food bags. Do not use stores, supermarkets or even garbage bags to save money or save time.
Cleanliness - a pot of hot water, a few drops of detergent, plus a soft scouring pad to clean all the dishes. It is not necessary to use strong alkaline cleaners like decontaminating powders to remove grease from food. When using a dishwasher, put plastic utensils on the top layer. Before using a new food container, it must be thoroughly washed to avoid mixing the dirt left in the production process into the food.
Everywhere - self-adhesive food bags and food cling film are the best choices for food packaging. In order to increase the flexibility of the product, part of the cling film is made of PVC. If you are concerned about the adverse effects of PVC on the human body, you can choose a product that does not contain plasticizers. Do not use a normal plastic container to heat in a microwave oven. When using a microwave to heat meals, be sure to place the food in a glass or ceramic dish for the microwave oven. If necessary, it is best to cover the dishes with a plastic wrap, but do not let them touch the food surface.
