Heat Sealable PET Film Description

Heat sealable PET film is a high-quality, biaxially oriented BOPET polyester film with a heat seal layer coating. This sealable film is typically single-sided heat sealable and can be used for both self-sealing and lamination heat sealing applications.

Our heat sealable polyester film has a wide temperature range, making it compatible with various packaging machines.

In addition, our heat sealable film forms a strong and reliable seal, ensuring product safety and freshness. Its resistance to high temperatures and non-toxic properties make it ideal for packaging foodstuffs, medicines, and products requiring high chemical stability. CloudFilm’s food-safe PET film is a packaging solution you can trust.

The film’s thickness ranges from 12 to 60 microns, so it can be adjusted to suit particular requirements.

Further information about our heat seal film products is available by contacting our professional service team.

Heat Sealable PET Film Applications

The applications of heat sealable PET film are broad. It is especially valued where high clarity, strong seals and higher temperature resistance are required compared with standard BOPP structures.

  1. Food tray and cup lidding

    • Used as lidding film for meat, ready meals, bakery trays, fruit and vegetable packs, yogurt and dairy cups.

    • The film’s stiffness and transparency give a premium look, while the heat-seal layer provides reliable, leak-free seals even under hot-fill or reheating conditions.

    • Typical structures: heat-sealable PET lidding film to APET/CPET/PP trays, PET/PE laminates for flow-wrap or pouch packs.

  2. Medical and pharmaceutical packaging

    • Applied as a lidding or sealing layer for blister packs, diagnostic kits, medical device trays and sterilizable pouches.

    • PET’s dimensional stability and chemical resistance help protect sensitive drugs and devices from moisture, oxygen and contamination.

    • Typical structures: PET sealing film / PET-PE laminates for medical pouches, PET lidding to specialized trays.

  3. Electronics and industrial components

    • Used to pack ICs, LEDs, connectors and other sensitive components where a clean, strong and dust-resistant seal is needed.

    • Anti-static or functional coatings can be combined through lamination to meet ESD and handling requirements.

    • Typical structures: PET/PE or PET/CPP bags and overwraps for components, reels and industrial parts.

  4. Daily chemical and personal care products

    • Suitable for cosmetics, personal care and household products, where clarity, branding and shelf appeal matter.

    • Heat-sealable PET can act as a printed outer web or sealing web in pouches and sachets, combining high-quality graphics with secure seals.

    • Typical structures: printed PET/PE, PET/CPP, PET sealing films with easy-open or peelable layers.In addition, heat sealable PET film is also used for textile, toy and hardware packaging, especially when a more rigid, high-temperature-resistant film is preferred over BOPP.

FAQ

Is PET Film Heat Sealable?

Standard PET (polyester) film is not inherently heat sealable at typical packaging temperatures. Its surface is chemically inert and has a relatively high melting point.

Heat sealable PET film is produced by adding a dedicated seal layer through coating or co-extrusion on one or both sides of the PET base film. This seal layer softens and bonds under heat and pressure, allowing the film to seal to itself, to PE/CPP sealant layers or to compatible trays. CloudFilm’s heat sealable PET grades are designed specifically for this purpose.

What is the heat sealable meaning?

Heat sealable refers to the property of a material that allows it to be sealed or bonded together using heat and pressure. In the context of packaging materials, such as films or foils, heat sealability is an important characteristic that enables the creation of airtight or watertight seals to protect the contents of a package.

When a heat sealable material is exposed to the appropriate temperature and pressure, usually with a heat sealing device or machine, the material’s surface layers soften and become tacky. As pressure is applied, these tacky layers come into contact and fuse, forming a strong bond upon cooling. This process is commonly used in packaging applications to seal bags, pouches, wrappers, and other types of containers.

Heat sealable materials are widely used in the food industry, pharmaceuticals, medical devices, and many other sectors where product protection, shelf life, and tamper evidence are important. Examples of heat sealable materials include certain plastics (such as polyethylene, polypropylene, and polyester with special coatings), laminates, and some metal foils.

What is Heat Sealable PET Film?

Heat Sealable PET Film is a polyester film that has been treated or coated to allow for heat sealing. This treatment makes it ideal for packaging applications requiring an airtight seal, enhancing product freshness and shelf life.

Can heat sealable PET film be used for food packaging?

Yes. Heat sealable PET film is widely used in food packaging, especially for tray lidding, cup lidding and high-temperature laminates. When you plan to use it for direct or indirect food contact, please inform us of:

  • The type of food (meat, ready meals, dairy, bakery, etc.)

  • The filling and storage conditions (hot-fill, chilled, frozen, microwave/oven use, etc.)

  • The target markets or regulations involved

CloudFilm can then recommend food-contact-grade films and provide available documentation to support your compliance process.
