Key Points of Heat Sealing Performance of Transparent Film Three-dimensional Packaging Machine Packaging Film

The key points of the heat sealing performance of the packaging film of the transparent film three-dimensional packaging machine mainly include the following aspects:

Heat sealing strength: The packaging film must have sufficient heat sealing strength to ensure that the heat sealing parts can be firmly bonded during the packaging process, preventing the product from scattering or being damaged due to poor heat sealing during transportation and storage. Insufficient heat sealing strength may lead to packaging leakage or product damage.

Heat sealing temperature range: The packaging film should have an appropriate heat sealing temperature range to adapt to different packaging machines and packaging requirements. If the heat sealing temperature range is too narrow, it may be necessary to frequently adjust the temperature during the packaging process, increasing the operational difficulty and cost. Meanwhile, an appropriate heat sealing temperature range also helps to ensure the consistency of heat sealing quality.

Heat sealing speed adaptability: The heat sealing performance of the packaging film should be able to match the heat sealing speed of the packaging machine. If the heat sealing speed is too fast and the heat sealing performance of the packaging film is insufficient, it may lead to an unstable heat seal. Conversely, if the heat sealing speed is too slow, it may affect the packaging efficiency.

The flatness of the film after heat sealing: The packaging film after heat sealing should remain flat without wrinkles or bubbles. Wrinkles or bubbles not only affect the aesthetic appearance of the packaging, but may also reduce its moisture-proof and dust-proof performance.

The influence of heat sealing on other properties of packaging film: The heat sealing process should not have a significant impact on other properties of the packaging film, such as tensile properties and transparency. If heat sealing causes the packaging film to become brittle, yellow or have a reduced transparency, it will affect the overall quality of the packaging and the display effect of the product.
