Isolation Layer BOPET Release Film

The Isolation Layer BOPET Release Film produced by Jincheng suppliers covers a full range of common industrial thicknesses from 12μm to 150μm. It is completely transparent with no impurities or fog points. Combined with the industry-standard double-sided differential corona treatment process, it balances the adhesion of the substrate and the release performance of the surface layer. It has excellent dimensional stability and high-temperature resistance, capable of withstanding short-term high-temperature processing conditions of 150-160℃. It does not shrink, deform or lose silicon in a high-temperature environment.

As a new environmentally friendly and recyclable isolation material, our Isolation Layer BOPET Release Film can fully replace the traditional paper release paper and is widely applicable to four core fields: adhesive products, composite processes, electronic protection, and disposable hygiene products. The factory has passed the ISO three major system certifications, is equipped with a professional R&D and quality inspection center, supports customized production and cross-border batch delivery, and is paired with five standardized packaging schemes to comprehensively ensure the quality of product transportation and usage.

Product performance testing (factory standardized final inspection)

1. Customized peel force performance test

Conduct batch-specific peel tests for the three coating versions of light, medium, and heavy silicon. Precisely calibrate the tensile parameters of each Isolation Layer BOPET Release Film to ensure that the customized peel force values have minimal error. Through repeated peel tests, the silicon layer on the film surface does not fall off or transfer, and after multiple repeated peelings, it still maintains a smooth release effect, suitable for high-frequency die-cutting and re-rolling production processes.

2. High-temperature heat resistance stability test

Simulate industrial production high-temperature conditions and conduct continuous baking tests at a 150°C and 160°C temperature gradient environment. The substrate does not shrink, does not warp, and does not become brittle. The performance of the silicone coating is stable, and there will be no aging, adhesion, or failure problems, ensuring the qualified rate of the finished products after high-temperature processing.

3. Double-sided corona dielectric constant stability test

Take samples from the head, tail, and middle of each roll of film for testing. The corona value is strictly stable within the standard range, with no significant fluctuations. After a 6-month static storage test at room temperature, the corona value attenuation is extremely low, and it still maintains excellent adhesion and coating compatibility after long-term storage.

4. Film surface cleanliness and light transmittance test

Use a fully automatic optical inspection instrument for full-frame scanning to check for defects such as crystal points, scratches, oil stains, and impurities on the film surface. The light transmittance meets the standard, and the haze is extremely low. The entire production process is carried out in a dust-free workshop, eliminating dust adhesion, and meeting the usage standards for high-cleanliness production scenarios in precision electronics and medical consumables.

5. Warehouse weather resistance simulation test

Simulate high and low temperature, dry and wet alternating warehouse environments to test the size stability and silicone layer adhesion of the film. The product can be adapted to conventional industrial warehouse environments, is not prone to moisture, aging, or performance degradation, and is suitable for enterprises' regular inventory turnover use.

FAQ

Q1: How to choose the type among the light silicon, medium silicon and heavy silicon specifications?

For low-viscosity products such as medical acne patches, fever-reducing patches, and thin stickers, the light silicon model is preferred; for regular self-adhesive labels and ordinary double-sided tapes, the medium silicon standard model is suitable; for high-viscosity foam tape, industrial strong glue, and thick-layer gel, it is recommended to customize the heavy silicon model, which can provide gel viscosity parameters and be precisely matched with the specifications by the technical team.

Q2: Can this Isolation Layer BOPET Release Film be used for continuous high-temperature processing?

The standard temperature resistance range of this product is 150-160℃, suitable for short-term high-temperature heat pressing, bonding, and coating processes, with stable performance and no silicon detachment or deformation; it is not recommended to undergo long-term continuous high-temperature baking to avoid aging of the silicon coating and affecting the peel-off effect.

Q3: Is there a minimum order quantity requirement for custom peel force parameters?

For regular off-the-shelf specifications, there is no minimum order quantity limit, and individual orders can be purchased; for exclusive customized peel strength, special cutting dimensions, there is a basic minimum order quantity, and you can contact the customer service to confirm the specific parameters and delivery date, and support sample confirmation of the effect before mass production.

Q4: What are the core advantages of this PET silicone oil film compared to traditional release paper?

Compared to traditional release paper, this product has no paper debris shedding, moisture-proof and humidity-resistant, high-temperature resistance, can be repeatedly lightly peeled, no dust pollution, suitable for high-cleanliness electronic, medical, and food packaging scenarios, and is also recyclable and environmentally compliant, with higher long-term usage cost-effectiveness.

Q5: Which packaging method is more suitable for export orders?

For domestic regular circulation, simple packaging or horizontal and vertical pallets can be selected; for cross-border shipping, long-distance transportation, priority should be given to using suspended protective pallets or export-specific moisture-proof pallets, combined with moisture-proof film, desiccant, and corner reinforcement, to effectively resist the humid and jolting environment of shipping, ensuring the integrity of the finished products.

Q6: Will the product's long-term storage affect its usage effect?

In a dry, ventilated, and cool environment, the product can be stored for more than 6 months without significant degradation of the corona value and peel-off performance; it is recommended to store according to the first-in-first-out principle to avoid long-term exposure to sunlight, humidity, and heavy stacking.
