What is the function of plastic wrap

Plastic wrap can be used to wrap fruits, vegetables, meat and other ingredients and put them in the refrigerator to reduce bacterial infection, prevent food from spoiling easily, prevent large-scale nutrient loss, and prevent problems such as remote controls becoming dirty, cosmetics leaking, and slippery carpets. It can effectively isolate toxic gases in the air and has many other functions, such as slimming legs.

Cling film may seem ordinary but it has many magical uses. For example, if you have not finished eating the fruits, vegetables, meat and other ingredients you bought, you can wrap them in plastic wrap and put them in the refrigerator. This can reduce bacterial infection, prevent food from spoiling easily, and protect the loss of nutrients in the food.

You can wrap the TV remote control with plastic wrap to prevent it from getting dirty. You can also unscrew the cap of the cosmetics bottle and apply a layer of plastic wrap to prevent the cosmetics from leaking. You can also put a layer of plastic wrap under a carpet that slides easily to increase friction and make the carpet more fixed.

Strong sealing and anti-corrosion are the advantages of plastic wrap. It can effectively isolate the wrapped items from bacteria and viruses in the air. Usually, plastic wrap can not only preserve food, but also has many functions such as slimming legs. However, it is not recommended to heat plastic wrap as it may produce toxic gases.

Cling film material classification

1. PE (polyethylene) cling film: the most common cling film on the market. It can be used to wrap vegetables, fruits, and leftovers. The only problem is that it is not resistant to high temperatures, so it is best not to put it in a microwave.

2. PVC (polyvinyl chloride) cling film: Most of it is used in farmers' markets and vegetable markets to wrap vegetables and agricultural products.

3. PVDC (polyvinylidene chloride) cling film: PMP (polymethylpentene) cling film: can withstand high temperatures of 140-180°C. These are the cling films marked "microwave safe", but do not put them in high-temperature ovens.

What kind of garbage does used plastic wrap belong to?

Used plastic wrap is recyclable.

Cling film is a type of plastic packaging product commonly used to preserve food. It has moderate oxygen permeability and moisture permeability, which can regulate the oxygen and moisture content around the preserved food, extend the shelf life of the food, and block dust to prevent food in the refrigerator from tainting flavors and becoming dehydrated and shrunken due to freezing.
