Heat Seal

Heat Seal Coating

Roymal’s heat seal coatings is typically based on acrylic chemistries. These heat seal coatings can be sealed coating to coating or coating to substrate depending on the end application. Typical heat sealing conditions have temperature ranges from 225-350°F with 40-80 psi pressure and 0.1-1.0 seconds dwell time. Applications include pouch and lid sealing. Peel strengths are coating weight and substrate dependent. Typical examples of laminations include paper to paper, paper to film, paper to foil, film to film and film to foil. These coatings are applied to paper, paperboard and film using the standard printing processes, i.e., rotogravure, flexographic and offset.

  1. Heat sealable coating

    We are looking for a water based heat sealable and peelable coating suitable for direct food contact applications.

    The requirements are as follows:

    1. Substrate= PET

    1. Heat sealable @ ~ 140o C and dwell time – 1sec

    2. Peel Force = ~1000 gf/25mm @ 1.5 gsm approx

    3. Coatings= water based emulsions / Dispersions

    4. Haze on PET Film= Less than 6%

    5. Container substrate on which coated film to be sealed = APET/PS/PVC etc.

    6. FDA compliances

    Based on above mentioned CTQs Please suggest some suitable grades which can be used to formulate the above coating.

    If any further information is required please reachout to me.

    Thanks and regards

  2. Good afternoon sir
    Hope all is well with you.

    We are in need of HEAT SEAL COATING suitable to coat on BOPET FILM which is giving seal strength 2500gm/25mm with ITSELF as well as with other substrates.

    Kindly confirm whether is there any grade available in your portfolio which can give seal strength 2500gm/25mm?

    If yes, kindly share TDS + MSDS of the same for our reference to enable us to proceed further.

    Awaiting your prompt confirmation sir.

    Best Regards
    Neha
