corona film

Superior printing and composite performance: corona treatment increases the roughness and polarity of the film surface, improves the adhesion of ink and glue, and makes the printing of pattern and text more solid and clear; composite products, such as PET composite with paper and aluminum foil, have a stable structure and reduce the risk of delamination.

 Packaging applications have many advantages: high transparency and gloss, show the effect of the product is good; good stiffness, packaging is straight; good physical and chemical properties, water resistance, moisture resistance, chemical corrosion resistance, to extend the shelf life.

Excellent electrical properties: corona treatment does not affect its own insulating properties, can be used for capacitors, electronic insulating materials, high security and stability.

Reasonable price of PET corona film is reflected in

Production cost

 - Stable cost of raw materials: the main raw material of PET corona film is polyester chips, which is relatively abundant in the chemical market supply, price fluctuations are relatively small, which provides a basis for the stable production and reasonable pricing of PET corona film.

- Production process is mature: after years of development, PET corona film production process has been more mature, the degree of automation of production equipment continues to improve, production efficiency has also been greatly improved, so that the unit cost of production of the product is reduced to a certain extent to ensure the reasonableness of its price.

 Performance and price ratio

 - Good performance: PET corona film has high transparency, good flexibility, excellent barrier properties, chemical resistance, etc., in packaging, printing, electronics and other fields have a wide range of applications. Compared with other materials with similar properties, the price of PET corona film is competitive and can provide users with a high performance to price ratio.

- Strong customizability: PET corona film can be customized according to the needs of different users, such as different thicknesses, widths, lengths, degree of corona treatment, etc., which meets the personalized needs of packaging materials for different industries and products. This customizability enables users to choose the most suitable product for themselves under the premise of meeting their own needs, further improving the cost-effectiveness of PET corona film.

 Market competition is sufficient

 - A large number of manufacturers: At present, the number of PET corona film manufacturers is large, and the market competition is relatively fierce. In order to compete for market share, each enterprise has taken measures to reduce production costs, improve product quality, optimize the level of service, and at the same time in the price will also make certain adjustments, so that the price of PET corona film is more reasonable.

- Competitive pressure of alternative products: In the packaging materials market, PET corona film is facing competition from other materials such as polyethylene film, polypropylene film, PVC film and so on. These alternative products may have certain differences with PET corona film in terms of certain performance and price, but they also bring certain constraints on the price of PET corona film, prompting it to remain at a reasonable level.
