More Information About OPP bag
What is OPP plastic bag?
OPP stands for Oriented Polypropylene, which is a type of plastic polymer that is commonly used for packaging purposes. OPP plastic bags are made from this material and are widely used for packaging and carrying a variety of products, such as food, clothing, and electronics.
OPP plastic bags are known for their clarity, strength, and durability. They are also resistant to moisture, chemicals, and punctures, which makes them ideal for storing and transporting a wide range of items. In addition, they are lightweight and flexible, which makes them easy to handle and store.
OPP plastic bags can be produced in various sizes, shapes, and thicknesses, depending on the intended use. They can be printed with custom designs or logos, making them a popular choice for branding and marketing purposes.

How are OPP Transparent Plastic Bags made?
OPP (Oriented Polypropylene) transparent plastic bags are made through a manufacturing process that involves the following steps:
1. Extrusion: The first step involves the extrusion of the OPP film. In this process, polypropylene granules are melted and extruded through a die to form a flat sheet of plastic film.
2. Orientation: Once the flat sheet of OPP film is formed, it is stretched in both machine and transverse directions (MD and TD) using a tenter frame. This stretching process, called orientation, imparts strength and durability to the film.
3. Printing: After orientation, the OPP film is printed with the desired design or label using a printing press. The printing is usually done using a flexographic or rotogravure printing process.
4. Conversion: Once the film is printed, it is cut and converted into the desired bag shape using a bag-making machine. The machine folds and seals the film to create the bag and can also add handles or other features.
5. Finishing: After the bags are formed, they are subjected to finishing processes such as trimming and punching to achieve the desired size and shape.
6. Quality Control: Finally, the OPP bags are subjected to quality control checks to ensure that they meet the required specifications for strength, durability, and transparency.
Overall, the manufacturing process for OPP transparent plastic bags involves extrusion, orientation, printing, conversion, finishing, and quality control steps to produce a high-quality and durable plastic bag.
