Exploring the Uniqueness and Versatility of Biaxially Oriented Polypropylene (BOPP) Films
Biaxially oriented polypropylene, abbreviated as BOPP, is a highly flexible film used globally to package a vast array of food and non-food items. An antifog BOPP film is a significant variant, showcasing these films' utility. Over the past few decades, the packaging industry has undergone tremendous changes driven by constant innovation. Efforts by leading packaging and anti-fog film manufacturers have resulted in remarkable advancements, with BOPP films being a notable example.
Unlike shrink films, BOPP films are used as an overwrap for numerous products. These packaging films are applied by wrapping over the product. BOPP films are commonly used in food packaging, gradually replacing cellophane, especially in cigarette and snack packaging. The primary reason is that BOPP packaging films are cost-effective and superior in performance.
Prominent Features and Attributes of BOPP Films
Increased Barrier Properties
BOPP films are favored in food packaging due to their unmatched barrier properties against water vapor and oxygen. Their resistance and flex-crack capabilities are also exceptional compared to polypropylene shrink films. These features ensure that food items remain quality-intact under various external conditions, making BOPP films an ideal choice.
Shelf Life Extension
The shelf life of food products is crucial for both consumers and manufacturers. BOPP films offer effective moisture and oxygen barriers, especially in their metalized form. These properties help extend the shelf life of products, providing optimal benefits for both consumers and manufacturers.
Seal Integrity
BOPP films are known for their excellent seal integrity due to their narrow gauge spread. Other beneficial features include:
- Excellent heat seal strength
- Lower seal initiation temperature
- Broad sealing window
- Good machinability
Sustainability
BOPP films are sustainable, with relatively low carbon footprints compared to other conventional plastic materials. They require less energy for conversion due to their low melting point. Reprocessed BOPP resin granules are widely used in manufacturing injection molded parts, sitting mats, chairs, tables, and automobile parts, among other applications.
Aesthetic and Graphics
BOPP films are popular for food packaging due to their aesthetic appeal and presentable features. They offer excellent transparency and high-quality graphics, making products visually appealing. White opaque variants provide superb whiteness with high opacity and unmatched gloss. Metalized variants help products stand out on retail shelves. Other procedures enhancing product aesthetics include:
- Excellent surface tension
- Foil stamping
- UV spot coating
- Embossing
Density
BOPP films' low density ensures better yields during conversion and supports the policy of minimal plastic consumption per piece. It also results in less weight per roll, facilitating easy handling during transportation and logistics.
Top Applications of BOPP Films
BOPP films' excellent features make them widely used in the national and global food packaging industry. Prominent application areas include:
- Bags, pouches, and labels
- Wrapping
- Adhesive tapes
- Packaging of personal care products
- Products with tamper-evident films
- Food and beverage packaging
- Cigarette and medical packaging
- Lamination and decorative applications
- Industrial applications
- Gift wrapping, flower sleeves, and bagging

BOPP film rolls possess the following characteristics:
Common Features
- Anti-fogging
- Printable
- Extended shelf life
- Solvent & acid-resistant
- Durable
Environmental Impact
Due to increasing controversies against plastic, BOPP manufacturers use polypropylene as a raw material. Polypropylene emits the lowest carbon dioxide compared to other plastics. The BOPP film production process is energy-efficient and recyclable, causing minimal environmental impact.
The Manufacturing Process of BOPP Film
BOPP is a multi-layer film with polypropylene at its core, which provides excellent mechanical properties and durability. Layers of BOPP film may contain functional additives and polymers to determine its characteristics. Common production methods include the Tubular process and Tenter Frame Sequential process.
1) Tubular Process
The tubular process involves extruding a thick plastic tube, stretching it through heaters, inflating it into a tubular bubble, and compressing it to achieve the required thickness. Although effective, it is less commonly used than the tenter frame process.
Figure 2: Tubular Process
2) Tenter Frame Process
In this method, a thick plastic sheet is softened at a low temperature and then stretched in two directions. Simultaneous or sequential orientation is used, with sequential orientation being more common.
