The fully automatic heat shrink packaging machine L-type packaging machine is suitable for various imported and domestic shrink films such as PE as packaging materials. After the product is sealed and cut, it directly enters the heat shrink packaging machine for packaging, greatly improving work efficiency and reducing energy consumption. Its main electrical components are imported components from foreign countries, which have stable performance, extremely low failure rate, long service life, and can work continuously for a long time, meeting the needs of large-scale production. The automatic bagging and heat shrink packaging machine adopts a DC motor for linear operation, so it does not require the air source configuration of traditional models, making it more convenient to use and wider in range. This is a major feature of the machine. After being packaged by the machine, the items have a beautiful appearance, are clean, dust-proof, moisture-proof, anti damage, and easy to handle and store. Greatly reduce product loss and have packaging cost advantages. In order to ensure the safety and effectiveness of the operator and the machine itself, the machine adopts advanced technology and is equipped with multiple automatic protection measures to ensure the safety of the machine and operators.
