Is stretch film the same as plastic wrap and plastic wrap, and which is thinner cling film or film?

It's not the same, the thickness is ah, the wrap film and the plastic wrap.

The use itself is different, the thickness of the general winding film is larger, mainly used in the industry, the cling film is needless to say, mainly to maintain the freshness of fruit food, cling film requirements are more environmentally friendly.

Take the plastic wrap produced by Tangtai Plastic Industry as an example, the material is PE film.

PVC cling film contains carcinogens, which are more harmful to the human body, so when purchasing cling film, PE cling film should be used.

It is not the same, the stretch film is an industrial film, and the cling film is a food film.

The stretch film plays a fixing role, and the plastic wrap plays a preservation role.

However, both membranes are dustproof and moisture-proof.

It is not the same, and the viscosity, and stretching, and penetrating are not as good as the stretch film.

It's not the same. The thickness is twice as bad, but the raw materials are basically the same.

Plastic wrap is a type of stretch film, but because it does not require as high self-adhesive properties as stretch film, the amount of polyisobutylene will be less, and polyisobutylene is mainly used to increase the flexibility and self-adhesion of the product.

Plastic wrap is a kind of plastic packaging products commonly used by people to keep fresh food, and the main plastic wrap on the market is: the first is polyethylene, which is mainly used for food packaging, such as fruits, vegetables, etc., including semi-finished products purchased in supermarkets are made of this material;

The second is called polyvinyl chloride, which can also be used in food packaging; The third is polyvinylidene chloride, which is mainly used for the packaging of some cooked foods. Because the plasticizers used in PVC cling film have carcinogenic effects, and the production cost of PVDC is too high, most domestic cling films tend to use PE as raw materials.

Stretch film, also known as stretch film and heat shrinkable film, is the first in China to use PVC as the base material, DOA as a plasticizer and self-adhesive to produce PVC stretch film. Due to environmental protection problems, high cost (relatively large proportion of PE, less unit packaging area), poor stretchability and other reasons, when the domestic production of PE stretch film began in 1994 and 1995, it was gradually eliminated. PE stretch film first used EVA as a self-adhesive material, but its cost is high, and there is a taste, and then the development of PIB, VLDPE as self-adhesive materials, the substrate is now mainly LLDPE, including C4, C6, C8 and metallocene PE (MPE).

The size of the commonly used plastic wrap is 50mm x 3 meters.

How to choose plastic wrap?

There are generally three ways to buy safe plastic wrap, that is, "one look, two touches and three burns".

A "look" to see if it has a product description, if it is covered with PE plastic wrap or polyethylene plastic wrap, you can use it with confidence.

Second, "touching" polyethylene fresh-keeping preparation film is generally poor in viscosity and transparency, and it is easy to open after rubbing it by hand, while polyvinyl chloride cling film has good transparency and viscosity, and it is not good after rubbing it by hand, and it is easy to stick to the hand.

After the three "burned" polyethylene cling film is ignited with fire, the flame is yellow, and it will not be extinguished from the source, there is a dripping of oil, and there is no pungent odor There are many specifications of cling film, and the commonly used specifications of cling film are 50mm * 3 meters or 5 meters. This way you can use plastic wrap that compares most pots and dishes at home, or covers a large cut watermelon! But it mainly depends on the use of plastic wrap you use to choose 1. When heating oily food, you should keep the plastic wrap and food in isolation, and do not make 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, cover the utensils with plastic wrap, and then use toothpicks and other needles to prick a few small holes in the plastic wrap 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, when the temperature in the microwave oven imitation cavity is higher, it will generally reach about 110, and when you need to heat the mold for a long time, you can pay attention to choosing a plastic wrap with high heat resistance, which is a very thin plastic film, which has "self-adhesiveness", which can be well attached to the container and isolate the food from the surrounding environment, so as to prevent the loss of food moisture and retain most of the fresh taste.

General film is not as thin as plastic wrap. If it's special-purpose, it's hard to say.

This is not certain, some films are thinner than plastic wrap.

The plastic wrap is not breathable, it can prevent moisture from escaping, and play a sealing role, so as to prevent the food from losing its original umami during storage, isolate the air, and prevent the food from oxidizing.

Plastic wrap is a very common daily necessities, it can be used to keep food fresh and isolate food with different smells, so is plastic wrap breathable? Let me explain it to you.

01 plastic wrap is a kind of plastic packaging products, usually made of ethylene as the mother and brother tease through polymerization reaction, plastic wrap can be divided into three categories: the first is polyethylene, referred to as PE; the second is polyvinyl chloride, referred to as PVC; The third is polyvinylidene chloride, or PVDC for short.

02 Polyethylene: This material is mainly used for food packaging, and this film is used for fruits and vegetables that we usually buy, including semi-finished products purchased in supermarkets.

03 Polyvinyl chloride: This material can also be used in food packaging, but it has a certain impact on the safety of the human body.

04 Polyvinylidene chloride: mainly used for the packaging of some cooked food, ham and other products.

05 Among the three kinds of slag and dust shed fresh film, the plastic wrap of PE and PVDC is safe for the human body and can be used with confidence, while the PVC plastic wrap contains carcinogenic substances and is more harmful to the human body, so PE plastic wrap should be used when purchasing plastic wrap.

Not breathable. Saran Wrap.

It can prevent moisture from escaping, play a sealing role, prevent food from losing its original umami during storage, isolate the air, and prevent food oxidation. Plastic wrap is a kind of plastic packaging products, made of ethylene as a masterbatch through polymerization reaction, plastic wrap can be divided into three categories: polyethylene.

Abbreviated as PE;Polyvinyl chloride.

Abbreviated as PVC;Polyvinylidene dichloride Zhaoxinfeng ethylene, referred to as PVDC. <

1. The plastic wrap can prevent the release of moisture, play a sealing role, prevent the food from losing its original flavor during storage, isolate the air, and prevent the food from oxidizing.

2. Plastic wrap is a kind of plastic packaging products, usually made of ethylene as the masterbatch through polymerization reaction, and the plastic wrap can be divided into three categories: the first is polyethylene, referred to as PE;the second is polyvinyl chloride, referred to as PVC; The third is polyvinylidene chloride, or PVDC for short.

3. Microwave oven.

Food heating, refrigerator food preservation, fresh and cooked food packaging, etc., are widely used in family life, supermarkets, hotels and restaurants and industrial production of food packaging.

<><1. When steaming the egg custard, after adding water to the bowl, skim off the foam on it first, and then cover the bowl with a layer of plastic wrap. The steamed egg custard will not have pores, and the surface is smooth, and the taste is delicate and accompanied.

2. No matter how you brush the cups and glass bottles at home, they will leave scale after drying, which is obviously very opaque, and the use of plastic wrap can solve this problem. Take a piece of clean plastic wrap, wrap it around your hand, and use it to wipe the glass, and the cup will be very translucent and clean.

3. The plastic lunch box is not messy and easy to clean when stained with oil. If you encounter this kind of problem in the future, you only need to wipe it with a piece of plastic wrap, and the oil stains that can't be washed off will be easily wiped off.

4. The socket in the kitchen can be sealed with plastic wrap when not in use, so that the oil will not be polluted to it, and the plastic wrap can be removed directly when used.

5. When you do **, you can apply a layer of plastic wrap on your face to strengthen the absorption of your face (it is best to wash it, of course, you still have to dig a hole in your nose and mouth, otherwise you won't be able to breathe).

The difference between stretch film and plastic wrap: Stretch film is used to wrap things. Supermarkets often use stretch film, such as punching a pallet of goods, and then you have to wrap the goods whole with stretch film.

In this way, when the goods are pulled by forklifts, they will not be scattered. Otherwise, as soon as the goods are pulled, they will all be poured.

Plastic wrap is used to wrap around food, such as eating leftovers, and wrapping it on a plate. Put it in the refrigerator to keep it fresh, and there are fruits, you can also use plastic wrap. Mainly refers to food.
