Heat Sealing
Heat sealable plastic films and materials
Heat sealable plastic films and materials are used in packaging, fluid handling, biomedical, pharmaceutical, and industrial applications where a plastic surface must bond, seal, release, or protect during a heat sealing process. Material selection depends on sealing temperature, chemical exposure, release requirements, barrier needs, and contact with sealing jaws or heated tooling.
PFA, FEP, and PCTFE films may be considered where chemical resistance, barrier performance, or low surface energy are required. PTFE tapes are often used on heat sealing jaws and heated surfaces to provide release, reduce sticking, and help protect equipment during sealing operations.
Use this page to compare plastic materials for heat sealing, then review the plastic properties table, ask a plastics expert, or get a quote to discuss material availability, sizing, documentation, or fabrication needs.
Curbell Plastics can help you:
- Compare heat sealable plastic films, fluoropolymer films, and PTFE tape materials for sealing applications.
- Evaluate material options for packaging, fluid handling, biomedical, pharmaceutical, and industrial heat sealing processes.
- Review sealing temperature, chemical exposure, release requirements, barrier needs, and equipment-contact requirements before selecting a material.
PCTFE
Fluoropolymer with outstanding dimensional stability, mechanical properties, and temperature range.
PFA
Flexible fluoropolymer that performs well in extreme temperature and harsh chemical environments.
