Abstract
Description
Technical Field
[0001] The utility model relates to the field of film structure heat sealing devices, in particular to a co-extrusion film flattening heat sealing device. Background Art
[0002] Co-extruded film is used in pure milk bags, express bags, and metal protective film. It is characterized by good tensile properties and good surface brightness. Flattening and heat sealing of food packaging film is a technology widely used in the packaging industry. Its principle is to heat the heat source to a certain temperature, and then use pressure to press the hot melted material to another object to form a seal. Heat sealing can be divided into direct heat sealing and indirect heat sealing. Direct heat sealing is to directly contact the heat source with the sealed material to instantly heat it to the heat sealing temperature; then use pressure to quickly cool and solidify it to form a honey seal. Back heat sealing is to heat the heat source to a certain temperature, transfer the heat to the sealed material by heat transfer, and then form a seal by pressure after reaching the heat sealing temperature.
[0003] When heat sealing food packaging film, if the food packaging film is not fixed in a flat state before the heat sealing operation, misaligned heat sealing may occur during heat sealing. In addition, when heat sealing multi-layer food packaging film, a flat heat sealing method is used, and some parts of the multi-layer food packaging film may not be in contact and not completely heat sealed.
