PCR Sealing Film and Foil Supplier

GenFollower PCR plate sealing films are a reliable method for sealing PCR plates. We offer a variety of sealing films, including optical films, heat-sealing aluminium foil, and pierceable films etc. Please inquire for more information.

Suitable for various experiments, including qPCR, PCR, and bacterial cell culture.
RNase- and DNase-free, heat-resistant plate sealing films are available.
Resist DMSO and other organic solvents for storage at low temperatures.
Primarily for PP plates; some items also suit PE, PS and PC.
Select the appropriate sealing method for your specific needs—pressure-sensitive, self-adhesive, or heat-sealing. See the FAQ for a detailed comparison.

Frequently Asked Questions

01. What is the MOQ for sealing films and foils?

The MOQ is 1 box, making it easy to start even for small projects.

02. Can you provide OEM PCR sealing films?

Absolutely – we offer fully branded OEM solutions for PCR sealing films. And if you want to change size, we also support dimension customisation of sealing films.
For more information on custom options, please see our OEM solution page.

03. Are these sealing films free from contaminants?

Yes. All GenFollower films and foils are guaranteed to be DNase, RNase, PCR-inhibitor, pyogen, and DNA-free, ensuring reliable results.

04. Are your sealing films pierceable — single-well or multi-well?

We offer pierceable sealing films. Whether single-well piercing or full 96-well piercing is supported will be stated in the product description.

05. Can they be used with samples containing DMSO?

The sealing films have good chemical resistance and are suitable for low-temperature storage of compounds in DMSO and other organic solvents.

06. Heat-sealing vs self-adhesive vs pressure-sensitive films and foils – how to decide?

a. Heat-sealing: Use a heat-sealer to melt the film edge and bond it to the plate rim.

Film: Low cost and very secure. Moderate barrier to air and moisture.
Foil: Superb barrier performance, but at a higher price.

b. Self-adhesive: Sticks on with hand or roller pressure. Simple and fast to apply.

Film: Perfect for quick, temporary seals. Less reliable in very hot or humid conditions.
Foil: Offers high barrier protection and easy application. Requires a robust adhesive layer for lasting tack.

c. Pressure-sensitive: Bonds are under pressure to activate the adhesive layer.

Film: Lower barrier, heat and chemical resistance than heat-sealing films. Adhesive may weaken in constant humidity.
Foil: Offers light, gas and moisture shielding barrier protection.

07. What is a sealing film?

A sealing film is a thin sheet used to cover PCR plates (for example, 96-well or 384-well plates) during thermal cycling. It:

Keeps samples airtight to prevent evaporation.
Stops one well from contaminating another.
Withstands the high and low temperatures of PCR.

There are two main types:

Film: Flexible polymer sheets (heat-seal, pressure-sensitive, self-adhesive, stretch film). Lightweight and easy to handle.
Foil: Ultra-thin metal sheets (primarily aluminium foil), often laminated to a plate. They offer the best protection against gas, light and moisture.

Clients Testimonials

The sealing films stick well and give a tight seal. Easy to apply, and they come off cleanly too. Great for everyday PCR work.
