I. What is BOPP film?

Definition

BOPP (Biaxially-Oriented Polypropylene) film is a type of plastic film that has a wide range of applications in the packaging, labeling, and laminating industries. It is produced by extruding polypropylene resin into a thin film and then stretching the film in two perpendicular directions, known as biaxial orientation. This process enhances the strength and durability of the film, making it resistant to tearing, puncturing, and other forms of damage.

BOPP Films are the substrate of choice for food packaging all over the world due to the inherent moisture barrier properties, seal ability, high clarity and graphic reproduction, and shelf appeal that they provide, as well as the best possibility of the pack having a monolayer or homogeneous structure.

It is most often used as a co-extruded heat-sealable reverse-printed film for the purpose of food packaging. In the field of labeling, it is favored because of the benefits it offers in terms of yield (the lowest density of 0.55 for the IML orange peel effect), as well as its recyclability with PP containers and other materials. BOPP Films are in high demand all over the world, which is mostly due to the growth of the flexible packaging sector.

Benefits of using BOPP film

BOPP film become a common type of plastic film used in a wide range of packaging, labeling, and laminating applications due to its numerous benefits. The following are some of the key advantages of using BOPP matt film:

Shelf life extension

The BOPP film offers the best moisture barrier of all the regularly used plastic films, and its metalized version offers the best oxygen barrier to the goods. These two characteristics of BOPP films are crucial for food packaging because they increase product shelf life and decrease food waste.

High clarity

BOPP film has excellent transparency, which makes it an ideal material for packaging applications where the visibility of the product is important. This clarity allows customers to see the product clearly, helping to increase sales and improve the overall aesthetic appeal of the packaging.

Product quality

Due to its limited gauge spread, BOPP film offers constant and exceptional seal integrity in addition to its barrier capabilities. The food packaging business also benefits from strong heat seal strength, reduced seal initiation temperature, a wide sealing window, and superior machinability.

Aesthetic/Graphics

Clear BOPP films' excellent transparency makes it possible to provide product packaging with a high degree of visual appeal. In this film, half-tone printing tasks with multicolor printing may be easily completed for high-quality graphics. Excellent gloss, great opacity, and exceptional whiteness in the white opaque film type provide product packaging with an appealing appearance.

The superb metallic look of the metalized film variant makes your goods stand out on the shelf. The ability to do post-lamination procedures like foil stamping, UV spot coating, and embossing to improve the visual appeal of product packaging is made possible by the material's high surface tension.

Versatility

BOPP film can be easily converted into bags, pouches, laminates, and other forms of packaging, which makes it a cost-effective and efficient solution for many packaging needs. Its versatility allows manufacturers to tailor the packaging to the specific needs of their product, whether it be for presentation, protection, or both.

Density

In comparison to all other regularly used flexible packaging films, BOPP films have a special quality. Low density promotes the idea of using less plastic per product by increasing yield during conversion. Low density leads to lighter rolls that are easier to handle since they weigh less per roll than other plastic films of the same length.

Sustainability

Is BOPP film recyclable? In comparison to other plastic film substrates like polyester, BOPP film has a comparatively low carbon footprint. Due to its eco-friendliness in flexible food packaging, BOPP Film is the second most favored substrate after cellulose film. Low melting point materials need less energy to change from one form to another. Reprocessed BOPP resin granules are often used to create injection molded components, furniture such as chairs and tables, and other home products like seat mats.

Cost-effectiveness

BOPP film is an economical choice for packaging and labeling, as it is readily available, easy to convert, and has a low cost per square foot compared to other materials. This cost-effectiveness makes it an attractive option for companies that are looking to reduce costs while still providing quality packaging for their products.

III. How is BOPP film made?

In the flexible packaging sector, BOPP (Biaxially-Oriented Polypropylene) film has been utilized for many years. It is well regarded for its affordable price, superior optical and mechanical features, and exceptional gas barrier qualities (particularly water vapor).
Below is a detailed demonstration of the BOPP film manufacturing process:

Step 1. Raw material feeding system

Isotactic Polypropylene, a semi-crystalline, thermoplastic polymer, serves as the primary raw material in the center layer. While ethylene-propylene copolymers and/or ethylene-butane-propylene copolymers are used for the outer layers. A hopper system is used to introduce these ingredients into the extruders.

Step 2. Extrusion

The materials are melted and heated to 200&#;230°C within the extruders before being fed into the extrusion head, where they emerge as a foil.

Step 3. The foil cooling

The foil is then brought into direct contact with a cylinder that has been chilled before being submerged in a water bath to cool the melt.

Step 4. Machine direction orientation (MDO)

The film is subsequently passed over many rollers, which raise the temperature and prepare the film for longitudinal stretching (machine direction). By moving the foil between the rollers that spin at increasing rates, stretching is accomplished. The polymer chains are aligned at this point after the foil has typically been stretched up to five times its original length. The mechanical qualities of the film may be improved at this step, and the thickness can be cut by up to five times.

The film is heated again after stretching to remove the tension created during stretching (annealing phase).

Step 5. Transverse direction orientation (TDO)

A quick-moving chain of metal jaws grabs the film on both edges once it exits the longitudinal stretching zone (tenter clips). The film is stretched transversely by the diverging rails after being heated up in an oven in the middle (i.e. stretching in the transverse direction up to 9 times its original width).

The macromolecules align at this point, but this time in a transverse orientation, improving the mechanical characteristics of the film and reducing its thickness by up to 9 times. After stretching, the chain and the film converge, allowing the film to balance off the tension that built up during stretching (annealing phase).

Step 6. Thickness measurement and flame treatment

The film enters a new processing step at which point the thickness is automatically measured (along the entire width). After that, one of the faces is given a flame or corona treatment to prepare the film for the subsequent conversion processes, specifically to change the surface that will serve as an anchor for materials like ink (for printing), glue (for laminating), or metal (metallization process).

Step 7. Reel winding

After being wound around a reel, the film is then sliced to the specific measurements.

Step 8. Film measurements

The following are the primary metrics that the final product is subject to:

Density, grammage, and thickness

Elastic modulus, elongation at break, and tensile strength

Haze (opacity) and Gloss (sparkling appearance)

The friction coefficient between films and between films and metals

Sealing strength and threshold °C

Temperature stability (heat shrinkage)
 

The film has at least three layers and a thickness between 15 and 60 microns; the center layer is the thickest and primarily responsible for the mechanical qualities, while the two outer layers provide the film with different characteristics (i.e. heat-sealing properties).

In order to completely fulfill the application criteria, additives may be added, depending on the ultimate application the film is intended for.

IV. BOPP film raw material

BOPP (Biaxially-Oriented Polypropylene) film is produced from PP (Polypropylene) plastic resins. This type of plastic is harder than PE and is considered to have the general characteristics of good tensile strength, and higher transparency than other kinds of plastic. Besides, BOPP film is also known as a thin film, with a thickness of 10 ~ 40 microns. It is due to the low density of PP particles, only 0.90 g/m3.

The packaging industry&#;s credo remains reduced, reuse, and recycle.&#; The most environmentally friendly packaging options that suit this concept are given below:

1. Recycled packaging

More recycling almost always corresponds to more development in today&#;s quest for sustainability. Packaging must fulfill several criteria to be recycled, including separability, labeling and coloring, and cleanliness. BOPP filmmakers are attempting to meet these standards with their innovative package designs, providing recyclable goods.

2. Packaging options that can be reused

Reusable packaging is now more accessible in the industry, trying to change how packaging is managed by being cut open and then tossed away to endure forced sterilization, rinsing, and eventual reuse&#;despite being harder to envisage and full fill the recyclable packaging.

3. The bioplastics revolution

Another rising trend in packing is the use of greater biopolymers as a replacement for fossil-fuel-based materials. Although bioplastics are often associated with biodegradable and compostable, they are not always disposable or biodegradable. Instead, they aid in decreasing production&#;s carbon footprint, which has substantial implications for sustainability.

4. Packaging reduction

Many manufacturers and company owners are looking at reducing packaging to the basic requirements to guarantee higher sustainability. This is particularly true when dealing with bulk foods and other goods that don&#;t need much packaging. Due to the circumstances, it is vital to choose packaging solutions that prioritize product quality and safety.

5. The influence of the customer

When it comes to boosting the durability of packaging materials, communicating with customers about the best ways to use and reuse packaging is equally critical. Your efforts to create sustainable packaging will pay off when customers are informed about using, managing, and recycling packaging.

Finding the proper packaging for the product is a question of finding solutions that meet the product&#;s specific demands, complement your brand&#;s look, and are within your budget. On the market today, there are several different sorts of packaging solutions. You may package and display new goods to customers. 

There is a lot to consider while picking the suitable packaging for a product. It is essential to figure out packaging that is both practical and accommodating of the content&#;s unique needs, but it is also crucial to pick packaging that displays your product and brand&#;s personality to draw customers&#; attention. When you include additional factors like sustainability and cost-effectiveness, the choice becomes more difficult.
