BOPP stands for Biaxially Oriented Polypropylene. It is a type of plastic film that is produced by stretching polypropylene molecules in both the machine and transverse directions. BOPP film is widely used in packaging, labeling, and other applications due to its excellent clarity, high tensile strength, moisture resistance, and dimensional stability.
The production process of BOPP film involves initially forming sheets or thick films from the melt of polypropylene polymer through an elongated die. Subsequently, in a specialized stretching machine, the material undergoes simultaneous or stepwise stretching in two perpendicular directions at predetermined temperatures and speeds. Finally, the film is subjected to appropriate cooling, heat treatment, or special processes (such as corona treatment, coating, etc.) for final processing.

NIAITE offers various BOPP film types to meet different packaging requirements.
BOPP film is a highly important material for flexible packaging.
BOPP film is colorless, odorless, tasteless, and non-toxic, it can be directly used in contact with both food and pharmaceuticals.
Due to the directional effect of the molecules, it possesses high tensile strength, impact resistance, rigidity, and toughness.
Excellent transparency, good gloss for premium appearance and product visibility.
The surface energy of BOPP film is low, and corona treatment is required before coating or printing. After corona treatment, BOPP film exhibits excellent printing adaptability, allowing for high-quality multi-color printing and achieving a beautiful appearance. Therefore, it is commonly used as the surface layer material for laminate films.
It has good barrier properties and moisture resistance, making it suitable for various packaging applications.
BOPP film also has its drawbacks that need to be considered in packaging applications.
BOPP film is prone to static electricity accumulation and lacks heat-sealing properties. On high-speed production lines, BOPP film is susceptible to static electricity, requiring the installation of static eliminators.
The initiation tear strength of BOPP film increases after stretching, but the secondary tear strength is low. Therefore, there should be no cuts or notches on both ends of the BOPP film surface. Otherwise, the film is prone to tearing during printing or lamination.
BOPP film has a lower elongation rate compared to PP, and its heat-sealing performance is inferior. It is not easy to seal independently, so it is commonly combined with films like PE that exhibit good heat-sealing properties when used.
According to the uses of BOPP, it can be categorized into the following types of BOPP films.
Generally used for printing, bag making, adhesive tapes, and composite with other substrates. Its characteristics include good uniformity, high strength, high transparency, low heat shrinkage, low moisture permeability, and moderate corona treatment.
The matte film is made by unidirectional stretching of matte masterbatch in a single layer, mainly used for the lamination of books, journals, annual report covers, cardboards, etc. It is also used in various packaging when combined with polyethylene film, cast polypropylene film, BOPP film, pearl film, metalized film, etc.
Used for the packaging of printed food and household items. It features excellent heat-sealing strength, outstanding UV barrier properties, a high-grade appearance with pearl luster, and high barrier properties.
Mainly used for printing and bag making. In addition to the characteristics of ordinary transparent film, it also has low-temperature heat-sealing properties, low friction coefficient, and low moisture permeability.
Used for high-speed cigarette packaging. Although the overall usage volume is not large, it is the most profitable product in the BOPP film. The production and sales of tobacco film have high technical requirements and significant entry costs.
A new type of plastic material and an environmentally friendly product. It has the characteristics of lightweight, high strength, tear resistance, good printability, light-shielding, UV resistance, durability, and economic and environmental protection.
Mainly used for vacuum packaging of flavored foods, agricultural products, as well as packaging for pharmaceuticals, cosmetics, and cigarettes. Additionally, aluminum-coated films are widely used as hot stamping materials and label materials in printing.
Features clear embossing, good imaging, and excellent transparency. It is widely used in anti-counterfeiting packaging for mobile communication cards, brand-name tobacco, alcohol, pharmaceuticals, etc.
Mainly used in the electronics field for AC motors, household appliances, power capacitors, etc. It is a top-tier product among BOPP film types.
The production volume of other film varieties is currently limited and awaits further market development. These include BOPP drawstring film, BOPP twist film, BOPP release film, BOPP wrapping film, etc.

BOPP (Biaxially Oriented Polypropylene) film is a versatile packaging material known for its excellent clarity, high gloss, moisture resistance, and cost-effectiveness. Its main advantages include superior transparency, good printability, excellent moisture barrier, and competitive pricing compared to other films.
BOPP-based packaging is ideal for products requiring excellent clarity, moisture protection, and cost-effective solutions. Common applications include snacks, confectionery, rewind films, labels, cosmetic packaging, and products where visual appeal and moisture barrier are important.
BOPP offers excellent clarity and moisture barrier at a lower cost than PET, but has lower stiffness and temperature resistance. PET provides superior stiffness and heat resistance but at a higher cost. BOPP is ideal for applications where clarity and moisture protection are priorities, while PET is better for premium applications requiring stiffness and heat resistance.
Yes, BOPP film is widely used for food packaging and is FDA-approved for food contact. It provides excellent moisture barrier protection, making it ideal for snacks, confectionery, and other food products requiring moisture protection.
Common BOPP film thicknesses include 20μm, 25μm, and 30μm. The selection depends on your specific application requirements, barrier needs, and cost considerations. Thicker films provide enhanced barrier and durability for demanding applications.
