As a supplier of Normal BOPP Film Jumbo Roll, I often get asked about the most suitable sealing methods for our product. In this blog post, I'll share some insights into the various sealing techniques that work well with Normal BOPP Film Jumbo Roll, along with their advantages and considerations.
Understanding Normal BOPP Film Jumbo Roll
Before delving into the sealing methods, it's important to understand what Normal BOPP Film Jumbo Roll is. BOPP, or Biaxially Oriented Polypropylene, is a popular packaging material known for its excellent clarity, high tensile strength, and moisture resistance. Normal BOPP Film Jumbo Roll is a standard version of BOPP film, typically used for a wide range of packaging applications, including food, consumer goods, and industrial products.

Heat Sealing
Heat sealing is one of the most common and effective methods for sealing Normal BOPP Film Jumbo Roll. This process involves applying heat to the film to melt the polymer and create a bond between the layers. There are several types of heat sealing techniques, each with its own advantages and applications.
Impulse Sealing
Impulse sealing is a quick and efficient method that uses a brief electrical impulse to generate heat. The heat is applied to the film through a heated element, which melts the polymer and forms a seal. Impulse sealing is ideal for sealing thin films, such as Normal BOPP Film Jumbo Roll, as it provides a strong and reliable seal without overheating the film. This method is commonly used in the packaging of food products, such as snacks and baked goods.
Continuous Heat Sealing
Continuous heat sealing is a more traditional method that uses a heated roller or bar to apply heat to the film continuously. This method is suitable for sealing thicker films and can provide a more uniform seal compared to impulse sealing. Continuous heat sealing is often used in the packaging of industrial products, such as electronics and automotive parts.
Ultrasonic Sealing
Ultrasonic sealing is a non-contact method that uses high-frequency ultrasonic vibrations to generate heat and create a seal. This method is particularly suitable for sealing films with complex shapes or irregular surfaces, as it can provide a precise and consistent seal. Ultrasonic sealing is commonly used in the packaging of medical products, such as syringes and IV bags.
Pressure Sealing
Pressure sealing is another method that can be used to seal Normal BOPP Film Jumbo Roll. This process involves applying pressure to the film to create a bond between the layers. There are several types of pressure sealing techniques, each with its own advantages and applications.
Hot Bar Sealing
Hot bar sealing is a simple and effective method that uses a heated bar to apply pressure and heat to the film. The heat melts the polymer, and the pressure forms a seal. Hot bar sealing is suitable for sealing a wide range of films, including Normal BOPP Film Jumbo Roll, and can provide a strong and reliable seal. This method is commonly used in the packaging of consumer goods, such as cosmetics and personal care products.
Cold Sealing
Cold sealing is a method that uses a pressure-sensitive adhesive to create a seal without the need for heat. This method is suitable for sealing films that are sensitive to heat, such as those containing heat-sensitive products or additives. Cold sealing is commonly used in the packaging of pharmaceutical products, such as tablets and capsules.
Adhesive Sealing
Adhesive sealing is a method that uses an adhesive to create a bond between the layers of the film. There are several types of adhesives available, each with its own properties and applications.
Solvent-Based Adhesives
Solvent-based adhesives are a traditional type of adhesive that uses a solvent to dissolve the polymer and create a bond. This method is suitable for sealing a wide range of films, including Normal BOPP Film Jumbo Roll, and can provide a strong and durable seal. However, solvent-based adhesives can be flammable and may require special handling and ventilation.
Water-Based Adhesives
Water-based adhesives are a more environmentally friendly alternative to solvent-based adhesives. They use water as a solvent, which makes them safer to use and easier to clean up. Water-based adhesives are suitable for sealing a wide range of films, including Normal BOPP Film Jumbo Roll, and can provide a strong and reliable seal. This method is commonly used in the packaging of food products, as it is considered to be a safe and hygienic option.
Hot Melt Adhesives
Hot melt adhesives are a type of adhesive that is applied in a molten state and solidifies upon cooling. This method is suitable for sealing films quickly and efficiently, and can provide a strong and durable seal. Hot melt adhesives are commonly used in the packaging of consumer goods, such as books and magazines.
Considerations for Sealing Normal BOPP Film Jumbo Roll
When choosing a sealing method for Normal BOPP Film Jumbo Roll, there are several factors to consider, including the type of film, the application, and the production requirements. Here are some key considerations to keep in mind:
Film Thickness
The thickness of the film can affect the choice of sealing method. Thinner films, such as Normal BOPP Film Jumbo Roll, are typically easier to seal using heat sealing methods, such as impulse sealing and ultrasonic sealing. Thicker films may require more robust sealing methods, such as continuous heat sealing or hot bar sealing.
Product Requirements
The type of product being packaged can also affect the choice of sealing method. For example, food products may require a hygienic and airtight seal, while industrial products may require a strong and durable seal. It's important to choose a sealing method that meets the specific requirements of the product being packaged.
Production Speed
The production speed can also be a factor in choosing a sealing method. Some sealing methods, such as impulse sealing and ultrasonic sealing, are faster than others, such as adhesive sealing. If production speed is a critical factor, it's important to choose a sealing method that can meet the production requirements.
Cost
The cost of the sealing method can also be a consideration. Some sealing methods, such as solvent-based adhesives, can be more expensive than others, such as impulse sealing. It's important to choose a sealing method that provides a good balance between cost and performance.
Conclusion
In conclusion, there are several sealing methods that are suitable for Normal BOPP Film Jumbo Roll, each with its own advantages and considerations. Heat sealing, pressure sealing, and adhesive sealing are all effective methods for sealing this type of film, and the choice of method will depend on the specific requirements of the application.
