PVC cling film and PE cling film are two common types of cling film on the market. Although they all have the function of preservation, there are some obvious differences in material, characteristics, use and safety. The following is a detailed comparison of the two types of cling film:

1. material

1. PVC cling film: PVC, namely polyvinyl chloride, is a thermoplastic. PVC cling film has excellent self-adhesion and transparency.
2. PE cling film: PE is polyethylene, which is also a commonly used plastic material. PE cling film has good flexibility and elasticity.

2. characteristics

1. PVC cling film:

* High temperature resistance: PVC cling film can withstand higher temperatures, so it is often used for packaging food heated in microwave ovens.
* Good water resistance: PVC cling film has good water resistance and can prevent moisture penetration.
* Poor stretchability: PVC has poor stretchability relative to PE cling film.

2. PE fresh-keeping film:

* Good flexibility: PE cling film has good flexibility and elasticity, and is easy to stretch.
* Air permeability: PE fresh-keeping film has good air permeability, which helps to keep food fresh.
* Low temperature brittle: In low temperature environment, PE cling film may become brittle and hard.

3. uses

1. PVC cling film: Due to its high temperature resistance, PVC cling film is often used in food packaging, kitchen supplies and microwave heating food packages. In addition, PVC cling film is also used in some occasions that require higher sealing, such as packaging electronic products.
2. PE fresh-keeping film: mainly used for food preservation, such as wrapping vegetables, fruits, leftovers, etc., to extend its shelf life. In addition, PE cling film is also commonly used in home storage, waterproof and moisture-proof.

4. security

1. PVC cling film: Under certain conditions, PVC cling film may release chemicals such as phthalates, causing food safety issues. Therefore, when using PVC cling film, direct contact with food should be avoided, especially foods with high fat content.
2. PE cling film: PE cling film is generally considered a safe food contact material. However, low-quality PE cling film may contain additives, which may also cause safety hazards when used for a long time or in contact with high-temperature food.

5. environmental protection

1. PVC cling film: Due to the energy consumption and environmental pollution problems in the PVC production process, some countries and regions have begun to restrict or prohibit the use of PVC cling film.
2. PE cling film: Relatively speaking, PE cling film performs well in environmental protection, and most countries and regions allow it to be used for food contact.

In summary, there are differences between PVC cling film and PE cling film in terms of material, characteristics, use, safety and environmental protection. When choosing to use, it should be considered according to actual needs and environment. Especially in terms of food safety, consumers should pay attention to the material and safety standards of plastic wrap to ensure that the plastic wrap used complies with relevant regulations and requirements. In addition, as people's awareness of environmental protection increases, choosing environmentally friendly plastic wrap will help protect the environment and human health.
