BOPP film quickly led to changes in the packaging materials industry

BOPP film has the advantages of light weight, non-toxic, odorless, moisture-proof, high mechanical strength, dimensional stability, good printing performance, high air tightness, good transparency, reasonable price and low pollution. It is known as the "Queen of Packaging" reputation. The application of BOPP film reduces society's use of paper packaging and strengthens the protection of forest resources.

BOPP has excellent printing performance, can be compounded with paper, PET and other substrates, has high definition and gloss, excellent ink absorption and coating adhesion, high tensile strength, excellent grease barrier properties, low Electrostatic properties, etc. It is widely used in the field of printing composites and is also used as packaging materials in tobacco and other fields.

Optical film: BOPP ordinary film, also known as optical film, is the most commonly used product among BOPP products. The light film itself is a waterproof plastic film. Through the light film, the surface of the label material that is not waterproof can be made waterproof; the light film makes the surface of the label sticker brighter, looks more high-end, and attracts attention; the light film can protect the printing of ink/content, making the label surface scratch-resistant and more durable. Therefore, optical films are widely used in various types of printing, food, and packaging of articles.

Features: The optical film is inherently waterproof; the optical film makes the label surface bright; the optical film can protect the printed content.

Purpose: printing items; packaging of food and items.

Matt film: Also called matte film, it mainly achieves the matting effect by absorbing and scattering light. It can generally improve the quality of the printing surface, but the price is relatively high and there are few domestic manufacturers, so it is often packaged in boxes. Used in food or high-end packaging. Matt film often does not have a heat sealing layer, so it is often used in combination with other films (such as CPP, BOPET).

Features: The film can be given a matte effect; the price is relatively high; there is no heat sealing layer.

Purpose; boxed video; high-end packaging.

Pearlescent film: It is mostly a 3-layer co-extruded stretch film. There is usually a heat sealing layer on the surface. It is common such as chopstick bags. The pearlescent film is often heat-sealed with its own heat sealing layer, so there will be a heat sealing section. The density of pearlescent films is mostly controlled below 0.7, which is conducive to cost savings; and common pearlescent films present a white, opaque pearlescent effect, have a certain light-blocking ability, and have a protective effect on products that need to be protected from light. Of course, pearlescent film is often combined with other films and used in food and daily necessities, such as ice cream, chocolate packaging and beverage bottle labels.

Features: There is generally a heat sealing layer on the surface; the density is mostly below 0.7; it presents a white, translucent pearlescent effect; it has a certain light-blocking ability.

Usage: food packaging; beverage bottle labels.

Aluminized film: Aluminized film is a composite flexible packaging material formed by plating an extremely thin layer of metallic aluminum on the surface of a plastic film using a special process. The most commonly used processing method is the vacuum aluminum plating method, which makes the surface of the plastic film Has a metallic luster. Because it has the characteristics of both plastic film and metal, it is a cheap, beautiful, excellent and practical packaging material. It is mainly used in the packaging of dry and puffed foods such as biscuits and the outer packaging of some medicines and cosmetics. .

Features: There is an extremely thin layer of metallic aluminum on the surface of the film; the surface has a metallic luster; it is a composite flexible packaging material that is cheap and beautiful, has excellent performance and is highly practical.

Uses: packaging of dry and puffed foods such as biscuits; outer packaging of medicines and cosmetics.

Laser film: Using computer dot matrix lithography, 3D true color holography, multiple and dynamic imaging and other technologies, the holographic image with rainbow dynamic and three-dimensional effects is transferred to the BOPP film, which is resistant to ink erosion, has high water vapor barrier ability, and can Better anti-static. Laser film is relatively rarely produced in China and has certain requirements for production technology. It is generally used for anti-counterfeiting and decorative packaging of high-end products, such as cigarettes, medicines, food and other packaging boxes.

Features: Resistant to ink erosion, high ability to block water vapor; better anti-static.

Purpose: anti-counterfeiting packaging for high-end products; packaging boxes for cigarettes, medicines, food, etc.

Advantages of BOPP film

BOPP film, biaxially oriented polypropylene film, refers to a film product made from polymer polypropylene as raw material and processed through stretching, cooling, heat treatment, coating and other processes. According to different properties, BOPP films can be divided into ordinary BOPP films and functional BOPP films; according to different uses, BOPP films can be divided into cigarette packaging films, metallized films, pearlescent films, matte films, etc.

Advantage:

BOPP film is colorless, odorless and non-toxic, and has the advantages of high tensile strength, impact strength, rigidity, toughness and good transparency. BOPP film needs to be corona treated before gluing or printing. After corona treatment, BOPP film has good printing adaptability and can be printed with colors to obtain exquisite appearance. Therefore, it is often used as the surface layer material of composite films.

Current status of BOPP film industry

BOPP film is an important type of flexible packaging material. It has the characteristics of toughness and wear resistance, non-toxic and odorless, transparent and light weight, as well as good moisture resistance, high impact strength, good air tightness and high tensile strength. It is currently used in new applications. Widely used in energy, electronics, printing, packaging, food, daily chemicals and other fields.

In recent years, with the continuous improvement of national living standards and the continuous upgrading of consumer demand, the domestic packaging material market has developed rapidly, and BOPP film, as an important type of flexible packaging material, has seen its market demand continue to increase.

Driven by the continued growth in demand, the number of companies entering the domestic BOPP film market continues to increase, and market competition becomes increasingly fierce. In recent years, against the background of the gradual efforts of local companies, domestic BOPP film production has continued to increase. In 2022, domestic BOPP film production has reached 450 million tons. East China, South China, and North China are the main distribution areas of domestic BOPP film production capacity.

From the current supply and demand situation, my country's BOPP film production and demand are currently showing a steady growth trend; from the supply and demand pattern, the market is showing an oversupply situation. However, after recent years of development, my country's BOPP film production technology has been continuously improved. At present, some high-end products have basically been domestically produced. Therefore, domestic products are also exported in large quantities to foreign countries on the basis of satisfying the domestic market. my country has become the main producer of BOPP films in the world. China and one of the major exporting countries, the industry development trend is improving.

BOPP film is an important type of flexible packaging material. It is widely used in electronics, automobiles, food, packaging and other fields. Driven by the rapid development of its application fields, the domestic BOPP film market demand continues to increase, and the industry shows a good development trend. At the same time, against the background of the continuous improvement of domestic green manufacturing levels and the continuous strengthening of national environmental awareness, the BOPP film industry is continuously upgrading in the direction of functionalization and environmental protection. At present, the market demand for functional BOPP films is increasing, but only some companies in my country have the mass production capabilities of high-end and special functional BOPP films. In the future, local companies will need to speed up the technological process, and there is huge room for industry growth.
