Application of Welding Modifier in Food Industry
Nowadays, with the continuous progress of society, in the packaging industry such as food and chemicals, the use of welding positioner is becoming more and more obvious. In addition to the wider weld seam, the whole welding process will not directly contact with plastic parts, mainly relying on non-contact systems to protect them, and will not cause any pollution to the products, let alone the need for them. Use additives or solvents. If the material used can reduce the polyolefin plastics on the surface, then there is no need to add the base material or auxiliary material to preheat, direct welding can obtain a higher sealing joint, welded products can replace iron and paper containers.

If the humidity is relatively high, paper packaging will be very prone to deformation and moisture, then its anti-seismic and impact performance will also be reduced, and the use of plastic sheets for welding with capped containers, can effectively solve this kind of failure. But if it is in high corrosion and high salt environment, iron containers will be more prone to corrosion and rust, while plastic containers can be used. As laser welding plastic containers are not only very simple in technology, but also relatively inexpensive, and can be reused, so in the near future it will replace iron and paper containers.
