OPP film can be enhanced with coatings or laminations to improve its barrier properties, making it suitable for products that require protection from moisture, gases, and light.
Versatility
OPP film is versatile and can be used for packaging a wide range of products, including snacks, baked goods, stationery, and more.
OPP film is one of the most widely used films in the world. A common application for polypropylene is as oriented polypropylene (OPP). This film has excellent moisture proof properties which makes this great for using normal inks which produces a very clear printing result. It is today a leading flexible packaging film second only to low density polyethylene in volume.
A thermoplastic polymer used in a variety of applications ranging from packaging, to carpets. The primary application of OPP film is in food packaging due to is good strength, high clarity, adequate barrier properties and relatively low cost compared to cellophane. It is in almost every part of your daily life. Polypropylene is very resistance to fatigue. So a plastic type hinge can be opened and closed over a 1000 times with no fatigue.
Most flip-top packaging has this. The melting process of polypropylene is achieved via extrusion and molding. The common shaping technique used is injection molding. Other techniques are blow molding and injection stretch blow molding. By having the ability to tailor certain grades with specific molecular properties during manufacturing makes for a large number of end-use applications. An example of this would be the use of an antistatic additive to help the polypropylene surface resist dirt and dust.
What Is the Difference Between CPP Film and OPP Film, And BOPP Films?
CPP Film: Casting film that is not stretched, the formula for which can be individually changed to produce a variety of functional PP films, including anti-fog, anti-static, anti-puncture, and fog mask films.
OPP Film: A transversely stretched, BOPP-like PP film used in tapes, labels, packaging, and other items.
Biaxially oriented polypropylene (BOPP) film: Is used to package items like food, clothing, cigarettes, and other daily essentials in bags with good gas barrier qualities. Longitudinal stretch PP film with high unidirectional tensile strength known as MOPP film is utilized in tire linings, strapping tapes, and item labels.
What Is the Melting Point of OPP Film?
OPP film composite bag has good transparency, better heat resistance and better barrier performance than CPP film. It is widely used in the outer layer of the composite bag and compounded with aluminum foil with good heat sealing, which greatly improves the rigidity, straightness and physical and mechanical properties of the composite film.
The heat resistance is good, the melting point is as high as 164-170 degrees Celsius, and the product does not deform when heated to 150 degrees Celsius without external pressure, which is an excellent property that many thermoplastics do not have.
What Is the Thickness of OPP Film?
| Thickness | Available Configurations (Film Thickness Mils/Adhesive Thickness Mils) | Available Finishes |
| Light (LIT) | 1.3 mils | Gloss, Matte |
| Standard (STD) | 1.5 mils (.5/1) | Gloss, Matte, Diamond Hard Velvet Matte |
| 3 mil | 5/2.5 | Gloss |
| 5 mil | 1/4 | Gloss |
Polypropylene is recyclable. OPP film can be separated from other plastic types, melted into a liquid, cooled, and turned into pellets, then used to form new plastics. However, polypropylene loses its strength and flexibility as it goes through the recycling process. It may be mixed with new PP to improve the quality of recycled products.
You should check if your local authority recycles such plastic types before placing any polypropylene products in your domestic recycling bin. Businesses can arrange commercial collections of plastic waste and specify polypropylene to ensure it's separated and recycled properly to avoid it ending up in landfill.
How OPP Film is Made?
This material is produced by melting high molecular weight polypropylene into a thin sheet through a narrow machine head. The material proceeds through a dedicated stretching machine simultaneously at a specific temperature and predefined speed.
The film can stretch in two vertical directions while being subjected to appropriate cooling or heat treatment. OPP film is tasteless and harmless with high impact strength. The OPP film has different properties due to the different processing methods.
The flat film method produces OPP film bags with a higher tensile ratio than the tubular film method. The shaping technique of extrusion and molding commonly used in injection molding is also used in the melting process of OPP. Sometimes, an antistatic additive is included to help the polypropylene surface resist dirt and dust.
How to Choose the Best OPP Films for You?
The packaging industry is large and expanding rapidly. OPP films are popular for packing items across various industries. There are many types of OPP films existing in the market. It is important to choose the right OPP film as per the requirements of your product.
