Description

This description sounds like you're talking about Polytetrafluoroethylene (PTFE) coated tapes. Here's a breakdown: * PTFE Coating: This is the key feature. PTFE is a unique material known for its: * High Temperature Resistance: It can withstand significant heat without melting or degrading, crucial for hot sealing processes. * Non-Stick Properties: PTFE's low surface energy prevents materials from adhering to it, ensuring clean seals and preventing product contamination. * Chemical Resistance: It's resistant to most chemicals, making it suitable for various packaging environments. * Applications: * Heat Sealing: As you mentioned, PTFE tapes are widely used to cover the sealing jaws of packaging machines. This prevents: * Product sticking to the jaws, causing messy seals and machine downtime. * Build-up of residues on the jaws, which can affect sealing performance. * Plastic Bag Sealing: The non-stick properties are essential for smooth and efficient sealing of plastic bags. * Supply Options: * Self-Wound: The tape is pre-wound onto a core for easy dispensing. * Release Liner: A peelable liner protects the adhesive until it's ready to be applied.
