The frequency of use of plastic wrap has increased dramatically in summer, and many families use plastic wrap when storing food, melons and fruits in the refrigerator, and most of the cooked foods in supermarkets are wrapped in a layer of plastic wrap.

According to experts, plastic wrap can block dust in the air, but the key depends on the composition of the plastic wrap, if the quality of the plastic wrap itself is not up to par or improper use, it not only can not keep fresh, but also may make food become poisonous, which is not conducive to human health.

Nowadays, food packaging products on the home or market include plastic wrap, plastic bags, plastic boxes, etc., and the main role of preservation is to retain water, quality and protect nutrients from loss. It is understood that there are three main raw materials for the production of plastic wrap, which are polyethylene.

PE), polyvinyl chloride.

PVC) and polyvinyl chloride (PVDC). Most of the plastic wrap on the market is made from polyethylene, which is produced without any plasticizers.

Recognized as the safest.

Since polyethylene is not as tightly sealed as the other two, many supermarkets choose the latter, but experiments have shown that this plastic wrap contains a plasticizer called ethylhexylammonia to increase its adhesion. The plasticizer has a positive effect on the human endocrine system.

It has a very damaging effect and can disrupt the body's hormone metabolism. This chemical can easily penetrate food, especially high-fat foods, and most cooked foods in supermarkets are high-fat foods. At the same time, this plastic wrap releases carcinogens when heated, so it cannot be directly wrapped in food for heating.

For food that uses plastic wrap, you can take the following measures: when you get home, tear off the plastic wrap, wrap the food in a food bag, and put it in the refrigerator. Food can also be packed in a glass or ceramic crisper with a lid.

If it is a container without a lid, try not to overfill the food when covering it with plastic wrap to prevent direct contact with the plastic wrap. If you are still concerned about contamination, you can remove the surface that has been in contact with plastic wrap to reduce the damage of harmful substances. It is best to use a crisper box made of glass or ceramic, followed by PP material.

made of plastic crisper box, and finally plastic wrap.

That's all we need to pay attention to, I hope it will be useful to you. Satisfied.

It depends on whether the plastic wrap you choose can be suitable for microwave ovens, and if it can withstand high temperatures, it can naturally be turned together. If you need to heat it for a long time, you can choose plastic wrap with high heat resistance. At present, most of the most advanced plastic wrap on the market is the same as the commonly used plastic bags, which are made of ethylene masterbatch as raw materials, and according to the different types of ethylene masterbatch, plastic wrap can be divided into three categories.

The first is polyethylene, referred to as PE, this material is mainly used for food packaging, we usually buy back fruits, vegetables with this film, including the semi-finished products purchased in the supermarket are used in this material; The second is polyvinyl chloride, referred to as PVC, this material can also be used in food packaging, but it has a certain impact on the safety of the human body; The third is polyvinylidene chloride, referred to as PVDC, which is mainly used for the packaging of some cooked foods, ham and other products. Among these three kinds of cling film, the cling film of PE and PVDC is safe for the human body and can be used with confidence, while PVC cling film contains carcinogenic substances and is more harmful to the human body. From a physical point of view, plastic wrap has moderate oxygen permeability and humidity permeability, which regulates the oxygen content and moisture content around the preserved product, blocks the dust in the air, and prolongs the shelf life of food.

Therefore, it is necessary to choose different plastic wraps for different foods. At present, the plastic wrap on the market is roughly divided into two categories, one is ordinary plastic wrap, which is suitable for refrigerator preservation; One is microwave wrap, which can be used for both refrigerator and microwave ovens. The latter kind of plastic wrap is far superior to ordinary plastic wrap in terms of heat resistance and non-toxicity.

Therefore, consumers should pay special attention to the choice of use and use itemized. [This paragraph] when using microwave plastic wrap 1When heating oily food, keep the plastic wrap and food in isolation and do not allow direct contact between the two.

When food is heated, the oil may reach a very high temperature, causing the plastic wrap to break and stick to the food. 2.When heating food, the utensils should be covered with plastic wrap, and then a few small holes should be pierced in the plastic wrap with toothpicks and other needles to facilitate the evaporation of water and prevent the plastic wrap from bursting due to gas expansion.

3.The maximum heat-resistant temperature marked by each brand of plastic wrap is different, some are about 10 different, and the temperature in the microwave oven will generally reach about 110 when it is high.

When heating leftovers, do you have a habit of sealing the plate with plastic wrap and then putting it in the microwave to heat up? From now on, please change this habit, because plastic wrap will release plasticizers after heating at high temperatures, which is toxic! Current research suggests that the general public's intake of plasticizers is mainly through diet, because food and water can absorb phthalate plasticizers through contact with plastic packaging, and plastic packaging should be used correctly to avoid the harm of plasticizers.
