The hot cutting machine is a kind of flexible packaging production equipment. The hot cutting machine is the last process in the production and processing of plastic flexible packaging. If the packaging quality is not high and unqualified, it will lead to the previous process, waste time and cause unnecessary losses.
The following content is the manufacturer of the hot cutting machine to teach you how to solve the problem of poor heat seal strength encountered by the hot cutting machine.
1. The use of heat aging promotes the hardening of the adhesive, which can improve the strength and heat resistance of the composite film.
2. When selecting heat-sealing conditions, select or improve the heat-sealing method according to the structure and heat-sealing state of the composite film, and cool immediately after heat-sealing.
3. Regularly check the shelf life and storage conditions of the heat-sealing film. Pay attention to the old batch number or heat seal film.
4. Increase the thickness of the heat-sealing layer film.
5. Change the type of heat-sealing film and choose an inner sealing film with anti-pollution heat-sealing performance.
6. Improve the heat sealing performance of the heat sealing layer.
7. After heat sealing, check the treatment degree of the heat cover and adjust the appropriate heat sealing temperature.
The above content is the eagerness machine manufacturer to teach you to solve the problem of poor heat seal strength encountered by the eagerness machine.
