BOPP film, or Biaxially Oriented Polypropylene film, is a highly versatile material widely used across industries such as packaging and labeling. This material is well-known for its exceptional strength, transparency, and flexibility, making it an ideal choice for improving product presentation and preservation. This article will explore everything you need to know about BOPP film, its characteristics, and the manufacturing process.
BOPP (Biaxially-Oriented Polypropylene) film is a type of plastic film made by stretching polypropylene resin in two perpendicular directions. This process, called biaxial orientation, enhances the film’s strength, flexibility, and durability, making it resistant to tearing, puncturing, and other forms of damage.
BOPP film is widely used across industries, especially in packaging, labeling, and laminating. Known for its moisture barrier properties, heat sealability, and high clarity, BOPP film is a preferred choice for food packaging. It is also recyclable and compatible with polypropylene (PP) containers, making it an eco-friendly option. Its global demand continues to grow, driven by the expansion of the flexible packaging sector.
BOPP film is renowned for its versatile properties, making it an essential material in packaging industry. Here are some key properties of BOPP film:
The most popular product is BOPP ordinary film, also called glossy film. It can be made waterproof by laminating glossy film on top of the non-waterproof pressure sensitive label material. The glossy film may protect the printed ink content, making the label’s surface scratch-resistant and more durable. Glossy film is frequently used in printing, food, and product packaging.
Metallized BOPP films are coated with a thin layer of metal (usually aluminum) to impart a metallic appearance and enhance barrier properties. This film is frequently used for flexible packaging of snacks, candies, pharmaceuticals and toiletries, providing superior shelf life and protection against moisture and oxygen.
BOPP holographic film is made up of thermoplastic. It is a visually attractive film, featuring holographic patterns. These films are available in both transparent and opaque. This type of lamination is mostly used to enhance brand packaging. It is mostly used in food, cosmetic, tobacco and alcohol packaging. It finds its applications in gift wrapping, security labels and decorative materials.
The principal way matte film produces its matt effect is by absorbing and reflecting optical fibers. Generally speaking, it can raise the quality of the printed surface, but the cost is quite expensive. It is frequently boxed up. Used in luxury or food packaging. Since matte film frequently lacks a heat-sealing layer, it is frequently combined with other films (such as cpp, bopet, etc.).
Printable BOPP film has excellent gloss and high transparency. BOPP films are known for their excellent printability. Therefore this film is an ideal solution when it comes to advertising or decorating a product. You can use both sides of treated glossy or matte BOPP films for this purpose. The printed side remains at the outer side while the inner side is joined (to the other film) with an adhesive.
Pearlescent film usually has its own heat-sealing layer for heat-sealing. The common pearlescent film presents a white, opaque pearlescent effect, has a certain light-blocking ability, and has a protective effect on products that need to be protected from light. Additionally, the pearlescent film is often combined with other films for food and daily necessities, such as ice cream, chocolate packaging and beverage bottle labels.
Step 1: Preparing raw material
The raw material system includes the process of batching, mixing and drying. The raw materials used in the production of Bopp film mainly include homopolymer polypropylene (HPP), stiffening agent, COPP, anti-adhesion agent (AB), anti-static agent (AS), lubricant and filler masterbatch.
Step 2: Extrusion
Inside the extruders, the materials are melted and brought to 200-230°C and then conveyed through the extrusion head, where they emerge in the form of foil.
Step 3: The foil cooling
The foil is then placed in direct contact with a cooled cylinder and immersed in a water bath to quench the melt.
Step 4: Machine direction orientation (MDO)
The film then passes over a series of rollers, which increase the temperature and prearrange it to stretch longitudinally (machine direction). The stretching is achieved by passing the foil between the rollers that run at increasing speeds. As a rule, the foil is stretched up to five times the initial length and, at this stage the polymer chains are aligned.
This stage allows the enhancement of the film’s mechanical properties, also, the thickness is reduced up to five times. After stretching, the film is heated once again in order to neutralize the stress accumulated during the stretching (annealing phase).
Step 5: Transverse direction orientation (TDO)
Once out of the longitudinal stretching zone, the film is gripped on both edges by a fast-moving chain of metal jaws (tenter clips). In the tenter, the film goes into an oven, where its temperature rises before being stretched transversely by the diverging rails (i.e. stretching in transverse direction up to 9 times its original width).
At this stage, the macromolecules align, this time in transverse direction, enhancing the film mechanical properties and reducing the thickness up to 9 times. Following the stretching stage, the chain and the film converge, so that the film neutralizes the stress accumulated during the stretching (annealing phase).
Step 6: Thickness measurement and flame treatment
The film reaches a new processing stage where it takes the automatic measurement of the thickness (along the entire width). Afterward, one of the faces is subject to the flame or corona treatment to make the film suitable for the following conversion activities, namely, modifying the surface, that is intended to anchor materials such as ink (printing process), adhesive (lamination process), or metal (metallization process).
Step 7: Reel winding
BOPP film is wrapped around a reel and is slit according to the requested dimensions.
BOPP film is widely used in the packaging of food and beverage products due to its high strength and durability, as well as its moisture resistance.
