-
Heat Sealing
Heat sealing uses controlled heat to melt a thin layer of film on the container, creating a bond with the lid. This method is widely used for plastic containers and offers a strong, tamper-evident seal. Variations include direct heat sealing, where the heating element contacts the film directly, and impulse sealing, where heat is applied for short bursts. Impulse sealing is particularly suitable for thinner films and reduces energy consumption.
-
Pressure Sealing
Pressure sealing relies on mechanical force to create a tight seal between the container and lid. This method is often used for foam containers or containers with pre-applied adhesive strips. While generally less expensive than heat sealing, it may not offer the same level of tamper resistance or seal strength. Pressure sealing is often suitable for lower-volume operations or situations where tamper evidence is less critical.
-
Ultrasonic Sealing
Ultrasonic sealing uses high-frequency sound waves to generate localized heat, fusing the container and lid materials together. This method is versatile and can be used with various materials, including plastics and non-woven fabrics.
