english Characteristics of Plastic packaging film
2025-04-11
Plastic packaging film has many characteristics, which makes it widely used in the packaging field. The following are its main characteristics:
1. Good barrier properties
It can effectively block the intrusion of gases such as oxygen and water vapor. It can prevent the oxidation of the packaged products and avoid moisture. For example, after packaging foods such as potato chips with Plastic packaging film, they can remain crisp for a long time and extend the shelf life of the product.
High tensile strength
2. Although the Plastic packaging film is thin, it has high tensile strength and is not easy to tear. During packaging and transportation, it can withstand a certain degree of stretching and pulling to ensure the integrity of the packaging. For some large objects packaged with plastic film, the film is not easy to break during transportation.
Good transparency
3. Most Plastic packaging films have good transparency, and consumers can directly see the internal products. For the packaging of fresh products such as fruits and vegetables and daily necessities, this feature helps to attract consumers and promote product sales. Consumers can intuitively select goods.
4. Excellent sealing performance
It is easy to seal by heating and other methods to form a closed packaging space. The sealing effect is reliable and can prevent product leakage and contamination. For example, for the packaging of cosmetics, sauces and other products, the sealed plastic film can prevent the contents from leaking and deteriorating.
5. Strong chemical resistance
It has a certain resistance to chemical substances such as acids and alkalis, can protect the packaged products from chemical erosion, maintain product stability, and is suitable for packaging some chemical products with certain corrosiveness.
6. Lightweight and flexible
It is light in weight and can reduce transportation costs. At the same time, it has good flexibility, which is convenient for wrapping products of various shapes and improving the adaptability of packaging. Whether it is square, round or irregular shaped items, it can be well packaged.
In general, these characteristics of plastic packaging film make it an ideal packaging material and play an important role in many fields such as food, medicine, and daily chemicals.
