BOPP stands for Biaxially-Oriented Polypropylene. It is a variant of polypropylene (PP) and this polypropylene is a thermoplastic polymer, also known as polypropene. So, PP, OPP, and BOPP are the Polypropylene derivatives. The best way to distinguish between PP, OPP and BOPP bags is by understanding their use in the real world objects. The NWPP material is used to make non-woven bags. These are treated to make them water or moisture absorbent. Sanitary napkins, diapers, air filters, etc are some of the common PP products. The same material is also used in the manufacture of thermal clothing as they provide a temperature barrier.

BOPP is basically polypropylene that is stretched flat and oriented with a system that stretches it in two directions. There are 3 common processes for making BOPP: 1. Tenter Frame Sequential Process 2. Simultaneous Tenter Frame Orientation and 3. Double Bubble Process.
Usage of BOPP
In the packaging sector, BOPP film is the most used material, actually, BOPP constitutes two-thirds of all biaxially oriented films. This packaging material is cheaper than laminate but it can be used on continuous heat sealed packaging machines. BOPP material is used in Food & Beverage Packaging, Medical Packaging, Personal care product packaging, Tamper Evident films, Laboratory items packaging, etc. When it comes to recycling it is suitable for blown film factories to recycle their in-house waste, in that way plain BOPP is completely recyclable material.
Biaxially oriented polypropylene abbreviated as BOPP is a kind of flexible film used around the globe for the packaging of a large number of food and non-food items. An antifog BOPP film is an important variant of such high utility films. Over the past few decades, the packaging industry has witnessed so many sea changes driven by constant innovation and efforts made by the leading packaging and anti fog film manufacturers to come up with something truly remarkable. BOPP films are the result of the same.
Just contrary to shrink films, the BOPP films are utilized as an overwrap film for the packaging of numerous products. These packaging films are applied by over-the-product wrapping. Most commonly, BOPP films find applications in food packaging. However, they have started replacing cellophane across applications, particularly cigarette and snack packaging. The primary reason behind this is that BOPP packaging films are cost-effective and superior in performance.
Some most prominent features and attributes of BOPP packaging films at a glance
Increased barrier properties
BOPP films most commonly find applications in the packaging of food products because they offer unmatched barrier properties to water vapor and oxygen. Their capacity to withstand resistance and flex-crack is also remarkable when compared to polypropylene shrink films. Food items call for high barrier capabilities so that they can stay quality-intact under all types of external conditions and circumstances, and BOPP films are simply matchless in that regard.
Shelf life extension
Be it buyer/consumer or original product manufacturer, the shelf life of food products plays a crucial role when it comes to getting and offering the best value for money. When compared to all other conventional forms of packaging materials, BOPP films offer a more effective moisture barrier to products, and when used in the metalized form, these films provide an even better oxygen barrier to whatever is packed using them. Both these amazing properties of these revolutionary packaging films play a very crucial role in increasing the shelf life of products benefiting both consumers and manufacturers optimally.
BOPP films help maintain consistent and excellent seal integrity
Other than excellent barrier properties, BOPP films are also well-known for offering outstanding seal integrity, primarily because of their extremely narrow gauge spread. Some other features and attributes of BOPP films that benefit the food packaging industry to maintain high product quality include the following:
Excellent heat seal strength
Lower seal initiation temperature
Broad sealing window, and
Good machinability.
Sustainability
Sustainability is yet another remarkable feature associated with Biaxially Oriented Polypropylene films. It is because these films come with relatively very low carbon footprints in comparison to many other conventional plastic substrates and materials. BOPP films, after cellulose films, are considered to be the second most utilized substrate for a large number of flexible food packaging solutions. Since the manufacturing material of BOPP films has a very low melting point, it calls for very low energy for an effective and efficient conversion from one form to other. This is the reason reprocessed granules of BOPP resin find applications on a large scale in the manufacturing of the following apart from just packaging solutions:
Injection molded parts
Sitting mats
Chair
Table
Automobile parts etc.
Aesthetic / Graphics
It is a well-established fact that BOPP films are most commonly used for food packaging which calls for extremely pleasing aesthetic graphics and other presentable features for increasing commercial viability of different food products. And, on this front also, BOPP films score very heavily over all other ones. These films offer excellent transparency and provide all the products with eye-catching aesthetics for an everlasting impact on the psychology of the buyers or the consumers. These films offer high-quality graphics ability because all types of half-tone printing jobs, carried out making use of multicolor printing, are also very easy with BOPP films.
The white opaque variants of BOPP films are well-known for offering superb whiteness with high opacity and unmatched gloss providing the packaged products with an extremely attractive look and feel. On the other hand, the metalized variants of BOPP films enrich different products to stand out in the crowd of other products while on the shelf across the retail stores. What&#;s more, to enhance the aesthetics of different products using BOPP films, different other procedures can also be carried out easily and cost-effectively because of:
Excellent surface tension
Post lamination operations such as foil stamping
UV spot coating, and
Embossing.
Density
Density is one of the most prominent properties associated with BOPP films. This uniqueness separates it from all other forms of flexible packaging materials. The low density of BOPP resins provides better yields during the conversion process and thus supports the policy or philosophy of less consumption of plastic per piece. Low density also creates less weight per roll resulting in ease of handling during transportation and logistics.
Some of the top applications areas of BOPP Films
BOPP films, due to their excellent features and characteristics, are comprehensively used in the national and global food packaging industry. Some of the most prominent application areas include the following:
Bags, pouches, and labels
Wrapping
Adhesive tapes
Packaging of personal care products
Products that call for tamper evident films
Food and beverage packaging
Cigarette, and medical packaging
Lamination, and decorative applications
Industrial applications
Gift wrapping, flower sleeves, and
Bagging, etc.

Due to the increasing controversies against the use of plastic, plastic has become taboo. Authorities have banned single-use plastic. To overcome this problem, global BOPP film manufacturers use polypropylene as their raw material. Polypropylene emits the lowest carbon dioxide in contrast with other plastics.
BOPP film manufacturing process is also safe for the environment. This process uses less energy. As the emphasis on energy conservation is increasing, BOPP is taking over conventional (plastic) packaging.
Moreover, BOPP is among the recyclable materials. Therefore, BOPP film manufacturing process takes place without toxic emissions, halogens, or toxic wastes. Thus, causing no hazardous effect on the environment.
The Manufacturing Process of Bopp Film
BOPP is a multi-layer film having polypropylene at its core with several additional layers. When polypropylene is orientated in two directions, it guarantees that the resulting BOPP film has excellent mechanical properties and durability in both these directions
Layers of BOPP film may also contain a combination of appropriate functional additives and polymers that determine its barrier properties, whiteness, opacity, gloss, or matting. So, the manufacturer is in complete control of film properties.
A BOPP film can be produced by several methods but three processes are most commonly used. These include the Tubular process and Tenter Frame Sequential process.
1)Tubular Process
In this process, BOPP film manufacturers create the sheet by extruding a thick plastic tube. After that, the tube passes through the stretching heaters and inflates into a tubular bubble.
Then the bubble is compressed, and the lay-flat stretches and gives the sheet its required thickness. Nevertheless, this process is not as commonly used as the tenter frame process.
Figure 2 Tubular Process
2)Tenter Frame Process
In this BOPP film manufacturing process, a thick plastic sheet is softened at a low temperature. Then it is 300 &#; 400% stretched in two directions.
There are two methods for the biaxial orientation &#; simultaneous or sequential. In the tubular process and some new-technology tenter frame processes, simultaneous orientation forms BOPP sheets.
However, most commonly, BOPP film manufacturers use sequential orientation to form polypropylene films.
Figure 3 Tenter Frame Process
Polypropylene Film Types
BOPP is available in many types. Namely:
Clear BOPP Plastic Film
These transparent films are most commonly used for food packaging, for example, pulses, nuts, fresh fruits, vegetables & meat, cookies, etc.
Pearlized BOPP Film
Ideal for printing and is a perfect inner sealant for products like chocolate, ice cream, and labels for soda drinks.
BOPP Thermal Lamination Film
It is an ideal solution for two-sided printing. These films are usually used for brochures, shopping bags, textbooks, leaflets, etc.
Matte Polypropylene Film
This film is also suitable for printing. It is appropriate for cable wrapping, printed pouches, and strip packaging.
Printable White BOPP Film
White BOPP plastic film gives fantastic printing results. Also, the fast colors with accurate printing enhance the quality of pouches and labels.
BOPP Film for Adhesive Tape
The versatile properties of BOPP plastic make it adequate for coating and printing. Therefore, manufacturers prefer using these films to create self-adhesive tapes. Furthermore, you can custom-print these tapes as well.

Difference between Paper and BOPP Film Packaging
There are two types of BOPP film manufacturing processes &#; tubular or tenter frame process. In both methods, the BOPP film manufacturers stretch the film in two directions to make it strong, tensile, and durable.
On the other hand, paper is not as flexible and robust as plastic.
Secondly, polypropylene film is resistant to water, oil, and chemicals. In contrast, paper cannot resist fluids.
A BOPP film is scratch and wear-resistant, unlike paper.
Is Bopp Film Recyclable?
Yes, the Biaxially oriented polypropylene film is recyclable. They have a low density yet excellent stiffness that allows for thin yet durable BOPP films. While recycling, it doesn&#;t degrade as much as other films. BOPP films can be easily recycled by mixing them in a polypropylene recycling stream.
