Thermal adhesion of thermoplastics and its composite materials can be determined
The national standard of thermoplastic plastic and its composite material hot cover thermal adhesion can be measured recently through expert review, which has taken an important step towards full implementation.
Detailed rules for the standard thermoplastic material and composite material thermal cover, at the end of the heat sealing just hasn't been cooled thermal viscous fluid (namely hot sticky strength) testing methods, to fill the domestic blank. There is no relevant national standards and industry standards Review meeting, from the national plastic products standardization technical committee, national packaging product quality supervision and inspection center of medical equipment products quality inspection center of shandong, experts at the national inspection, academic institutions, such as the standard version, test report and other material had serious discussions and put forward modify opinions, as equivalent to the draft standard has with the international standard and technical level.
Thermal adhesion is the stripping force that the heat sealing part of the material is not cooled after the heat sealing. In actual production, the thermal adhesion of the packaging materials directly affects the filling efficiency and bag rate of the production line. At present, there is a mature test standard for heat-viscous energy in the world - ASTM F1921, but it is still in the blank phase, and the standard demand is extremely urgent. To this, by the haidian district of Beijing product quality supervision and inspection, jinan lincom mechanical and electrical technology co., LTD., a number of institutions such as enterprises and technical personnel to form the standard drafting team, after a lot of industry research and foreign standards, at the same time complementary with lincom hot glue pull machine test, lasted three years, eventually formed the draft standard edition. Next, the draft will be further improved, and the formal implementation will provide strong quantitative support for the reasonable selection and use of packaging materials.
