Non Silicone Release Film

Films Protection Company is a non silicone release film manufacturer producing clear PET-based release materials for adhesive processes that need a silicone-free release liner, clean peeling, and controlled contamination risk. This film is used when coating, bonding, printing, optical assembly, or electronics adhesive processing is sensitive to silicone-related transfer. Samples can be checked for no silicone transfer observation, release force consistency, and adhesive surface cleanliness before production use.

Product Overview

Non silicone release film is made for adhesive systems where the released surface must stay clean, not only easy to peel. The PET carrier gives stable thickness, good clarity, and reliable handling during slitting, die cutting, transfer, and lamination. A non-silicone release coating forms a low migration separation layer on one side. For teams using PET film and polyester film as general wording, the guide on PET polyester film terminology can help confirm when non-silicone release performance is needed instead of ordinary clear PET film.

For silicone-sensitive processes, small contamination marks may affect bonding strength, coating wet-out, print acceptance, or laminate clarity after liner removal. This film is used for electronics adhesive die cutting, FPC adhesive process liners, optical adhesive material protection, clean interleaf use, and transparent adhesive laminate support.

Common PET thickness choices such as 25 um, 36 um, 50 um, 75 um, and 100 um are reviewed with curl, flatness, roll tension, and cutting edge condition. Typical factory test ranges include 20-800 g/inch release force and +/-1 mm slitting width tolerance. Release level can be matched with acrylic, rubber-based, hot melt, or specialty adhesive systems after sample testing. Release-force data should be reviewed separately from PET film chemical resistance data when the liner may contact cleaners, solvents, oils, or process chemicals.

Benefits

• Helps control contamination risk in silicone-sensitive adhesive and coating processes.
• Non-silicone coated side supports cleaner peeling from pressure sensitive adhesive layers.
• Clear PET carrier gives stable thickness for slitting, die cutting, and lamination work.
• Release force can be matched to adhesive chemistry, dwell time, and converting speed.
• Residual adhesion can be reviewed as an 85% typical reference after sample testing.
• Surface checks include particles, scratches, bubbles, coating marks, curl, and flatness.

When Should Non Silicone Release Film Be Selected for Adhesive Processing?

Non silicone release film should be selected when the next adhesive, coating, printing, or bonding process cannot accept silicone-related contamination. It is useful for electronics adhesive processing, transparent adhesive laminate protection, clean interleaf use, and pressure sensitive adhesive die cutting where the bonding side must remain clean. The coated side should be tested with the actual adhesive layer to confirm smooth peeling, low surface contamination, and stable subsequent adhesion under expected dwell time and converting temperature.

Applications

• Electronics adhesive release liner for precision die cutting and transfer processing.
• Pressure sensitive release liner for acrylic, rubber-based, hot melt, or specialty adhesive.
• Clear release film roll for slitting, sheeting, converting, and pilot validation.
• PET transparent release films for coating, bonding, printing, or lamination trials.
• Clean release interleaf for adhesive films requiring low contamination contact.
• Transparent adhesive laminate support for display module and optical assembly materials.

How Can Silicone Transfer Risk Be Checked Before Production Use?

Silicone transfer risk should be checked with release force, surface cleanliness, and later adhesion performance. A practical sample review can include release force consistency across the roll width, adhesive contamination observation under clean lighting, particle and coating mark inspection, and subsequent adhesion comparison after transfer to the target substrate. For electronics adhesive die cutting or transparent adhesive lamination, curl, flatness, edge cleanliness, clean slit edge, and smooth separation should also be reviewed because small defects may affect alignment or bonding quality.

FAQ

What is the main function of non silicone release film?

It provides a silicone-free separation surface for clean adhesive release and helps reduce silicone-related contamination risk in bonding, coating, printing, optical assembly, and electronics adhesive processes.

Can the release force be adjusted?

Yes. Release force can be adjusted after sample confirmation with the actual adhesive system. Typical factory test range is 20-800 g/inch.

Is this film suitable for transparent adhesive materials?

Yes. It can support transparent adhesive laminates when the adhesive surface requires clean release, low visible contamination, stable flatness, and smooth separation.

What should be tested before production approval?

Recommended checks include release force consistency, silicone transfer check, adhesive contamination test, surface cleanliness observation, curl and flatness, clean slit edge observation, and subsequent adhesion.
