The silicone-coated film is ultra-clear and highly durable, perfect for mounting presses. This film is silicone-coated on both sides, creating an ideal release film for hot tables and our Hot Vacuum Glass Press. It permits work to be observed during the mounting process for superior accuracy.
Moreover, silicone-coated film supplier’s exceptional release properties consider Silicone coated PET films blending with inherent polyester film characteristics such as low shrinkage, high mechanical strength, clarity, and chemical resistance.
Enormously high levels of preserving the silicone layer on the PET film reduce backside transfer, which is known to be existing in most off-line coated release materials. Also, this silicone system is highly well attached to the film surface. So, the release force of the film is adjusted to fit most standard adhesives significantly, mainly water-based acrylic adhesives, but can be changed to user needs over a wide range from easy to tight release.
Here, you can read about everything related to silicon-coated film, including its benefits, applications, and unique features.
Features of silicone-coated film
silicone coated film suppliers believe that the PET release film, silicone-coated pet film, creates a cleanroom environment, critical parts like coating head at 1000 class cleanroom. The PET release film has the following features:
- cleaned environment manufacture, high pristine condition, and processing
- Appearance without scratches, no wrinkles, good smoothness, no dirty, no crystal points;
- Uniform coating
- High residual adhesion rate (≥85%), no performance impact on the material, little silicon transfer, no pollution;
- Higher easy release properties
- Friendly with a wide variety of adhesive
Why choose a silicon-coated film?
The silicon-coated film is highly essential. It has film HDPE(High-Density Polyethylene), which releases film/ BOPP (Biaxially Oriented Polypropylene)/PET and has one very stable silicone release coat side. It is mainly appropriate for extrusion-coated goods and hot melt adhesives. The opposite side of the concern is corona treated and tested so, and it can be produced if required.
Benefits of silicon-coated film
The silicones product line for release liners is accessible in multiple designs, making it versatile and suitable for your coating systems and requirements: solventless UV (both cationic and free-radical) solvent-borne, solventless thermal, and emulsion systems.
Also, silicones are highly beneficial as they constantly strive to improve more sustainable solutions, making silicones an essential aid for your eco-friendly initiatives. They help decrease greenhouse gas emissions by refining energy efficiency and spreading the lifespan of your manufactured goods. Reliant on your application, you can recycle or reuse your silicone release liner.
Some of the silicone coated film suppliers certify multiple benefits to the consumer, such as:
- It offers minor thickness tolerance, high transparency, fine malleability, and a low heat contractility rate.
- There is no pollution or enactment impact on the material.
- It has a high-quality look with no scrapes, superior smoothness, minor crinkles, zero dirt or crystal points.
- They are appropriate for sensitive adhesive uses by functioning as the release liners and carrier films.
- We offer practical and smooth, and it effectively avoids many drawbacks and evenly coated films free from avulsions, creases, pinholes, bubbles, granules, etc.
- They are manageable in various pet film thicknesses.
- They are highly cost-effective
- It has a high light transmission and heat resistance.
Silicone Coated Film- Application
Silicone Coated Film supplier suggests that these release liners have a wide array of marketing value and applications. It is essential to attain an impeccable coating to protect and supply materials like pressure-sensitive adhesives (PSA) used in labels, tapes, and destinations.
Moreover, they are also fantastic process aids besides the protection of self-adhesive or sticky materials and offer non-stick hygienic solutions for cooking and baking. Also, they enable casting and composite production processes and are highly helpful in protecting hot melt adhesive, which is coated on a carrier bag beforehand.
Some of the applications of these adhesives are:
- Medical, Label and Adhesive tape manufacturing
- Self-adhesive labels as kid’s stickers, warning or promotional labels
- Suitable for numerous fields like IT/Display (Mobile phone, PDA & LCD)
- Protective films for self-adhesive industrial roofing
- Electrical & Electronics
- Automotive
- Casting papers for artificial leather
- Self-adhesive labels for packaging decoration or variable information (bar code/QR code)
- Self-adhesive bandages and medical devices such as ECG pads
- Graphic art laminates for marketing, signing, or interior design
- Functional food and cooking papers for non-stick performance and grease, water & vapor control
- Process and casting papers for “pre-preg” composite production and artificial leather
- Tapes for the construction, automotive, and electronics industry
- Adhesive protectors for hygiene applications (baby diapers, feminine hygiene, etc.)
Types of a silicon coating film
There are different types for silicone coating, such as cast polypropylene (CPP), low density and high-density polyethylene (LDPE/HDPE), and oriented polypropylene (mOPP and BOPP). Also, there are amorphous polyester (APET), polystyrene, biaxially oriented polyester (PET), and polyvinyl chloride (PVC).
Films have some noticeable differences parallel to the paper. Paper usually is not extensible to any grade and is moderately heat resistant, but films can be opaque, transparent, or self-colored+. Some are tear-resistance can be very high or very low, easily deformed or conformable, some will shrink some temperature resistance.
Low density and high-density polyethylene (LDPE/HDPE)
LDPE and HDPE can be very tear-resistant and can be cut with a hot wire, so they have used them for creating tapes and making sealable PE packaging bags for objects of clothing or magazines. HDPE produces bitumen tapes Because of their high tear resistance, anticorrosion pipeline wrapping, and flashing tapes where elimination of the liner without tearing is a requisite function.
Oriented polypropylene (mOPP and BOPP)
Cast and oriented PP are composed of the same resin but have diverse characteristics because of the alignment during manufacture. mOPP extrudes similarly, but the rewind runs much quicker than the extruder, so the film is strained (oriented) in the machine direction. The machine direction gives very high tensile strength (but insufficient tear strength) and high tear strength in the cross direction. mOPP is used to make tear tapes for packaging and for high requirement tapes where the resistance to CD tear is significant.
On the other hand, bOPP is composed of mOPP but absorbed the film edges on a stenter frame that stretches the film in the cross direction. Also, it produces the regular OPP film you see for packaging cigarettes, flower wrapping, CDs, etc.
Amorphous Polyester (APET)
Amorphous PET or APET trails the cast PP route and stretches a polyester film that is thermoformable at low temperatures. Normal PET is created in the cast strengthener route and has a virtuous heat resistance and low shrinkage.
APET silicone release liners are used in the liner, likely to be thermoformed into a 3D shape to create electrodes for heart activity monitoring. The conductive gel adhesive wants to be confined in a hollow to retard any tendency for drying out.
Biaxially oriented polyester (PET)
PET and BOPP films are useful for high clarity labels (clear on clear) anywhere the face material is produced. And, a transparent adhesive is used to mimic a vessel with direct print. Typically, a PET liner is effective with a PET face material and Bopp with a PP face. The thinness (with good profile) and high tensile strength of these liners ensure faster labeling speeds and more labels per reel. Filmic liners also permit high humidity conditions such as splashing. Which could cause paper breaks and bottling lines without condensation.
Filmic liners do not usually undergo dust production through slitting. And, benefit clean rooms and laminate where dust could build up on the adhesive edges. The main disadvantage for films is invisibility because of the high clarity and static electricity generation. It can be challenging to see where the liner is to eliminate it. Once detached, it can stick to outsides rather than being quickly disposed of. So, to mitigate these effects, the color filmic liners are either added to pigment direct to the Silicone to make it visible or with ink under the Silicone or and additives are available to reduce static generation slightly.
