PSD Hot and Cold Seal Jaws are designed to correct standard seal film industry issues. For packaging that requires heat sealing, LAKO TOOL has developed a hot seal polymer to withstand 300°F (150°C).  This provides superior sealing versus other heat sealing processes and provides many benefits.

  • Improved seal strength, even with lighter gauge film

  • Seals through wrinkles, channel leakers, and transition areas around the fin seal while reducing or eliminating seal fractures

  • Eliminates metal-to-metal contact that reduces time-consuming machine wear

  • Enables consistent sealing without ongoing quality control adjustments for minor film variations

  • LAKO's hot polymer PSD inserts can be replaced in minutes, without disturbing settings for knives and anvils or causing downtime

  • Re-stocking program available to avoid downtime
