Why Commercial Operations and Domestic Kitchens Prefer PTFE-Coated Fiberglass Fabric as Baking Sheet/Tray Liners

Please visit our website for more information on this topic.

Baking sheets and baking tray liners are regularly used in both commercial operations and domestic kitchens. Choosing the right baking sheet and tray liner material can greatly impact your baking experience. PTFE-coated fiberglass fabric baking sheets and tray liners are a safe way to improve your baking efficiency.

Why Should You Use Baking Sheet or Baking Tray Liners?

• Increases Kitchen Productivity: Using a liner reduces cleanup time. You spend less time scrubbing and more time cooking.
• Improves Food Quality: Liner material such as the PTFE-coated fiberglass fabric is FDA compliant and it eliminates direct food-to-hot metal contact. This prevents the moisture in the food from “scalding off” and makes the food more flavorful.
• Makes Food Safer: Since the food cooked never comes in contact with the pan, the chance of surface contamination is eliminated.
• Reduces Wastage: Clean release of your dough-based product reduces the amount of residue that would have otherwise accumulated on your baking sheet or tray.

While there are a number of ways to line your baking trays and sheets, PTFE coating is popularly used for baking purposes as it can withstand the high temperatures associated with baking ovens–up to 500°F / 260°C.

The advantages of using PTFE-coated fiberglass fabric as baking sheets or baking tray liners over metal baking sheets coated with PTFE are reduced downtime and cost savings. When the PTFE coating on the metal baking sheets becomes worn, the sheets have to be taken offline and sent to the coating vendor to be re-coated.  If they can’t be re-coated they are required to be replaced entirely. Re-coating usually takes approximately seven to ten days. What that means for your business is seven to ten days of downtime. In order to limit revenue loss caused by prolonged downtimes, bakeries and other food processing facilities tend to purchase and maintain more trays than necessary.

On the other hand, lining your baking sheets is a more economically viable option since all you have to do is cut a sheet to size and place it within the tray, which hardly takes a minute.

To ensure a hassle-free baking experience using PTFE-coated fiberglass fabric liners, consider these factors:

• Baking Temperature – Oven temperatures should not exceed 500°F / 260°C which is the maximum operating temperature of the PTFE-coated fiberglass fabric.
• Sheet Thickness – A 3 mil. (.003”) thick PTFE-coated fiberglass sheet is flexible and the least expensive, but it has a shorter use-life. A 5 mil. (.005”) to 10 mil. (.010”) PTFE-coated fiberglass sheet is less flexible and more expensive. However, it has a longer use-life. Choose the sheet thickness based on how long you intend to use it for.
• Cleaning Method – It is generally recommended to use soap and water to clean the surface of the PTFE-coated fiberglass sheet. Avoid the use of abrasives as they will reduce the sheets’ effectiveness and negatively impact its use-life.

Based on years of experience, and sampling many products, we can offer market recommendations for what suits your needs for which application. Our fabrics are made from woven fiberglass cloth with a clear PTFE coating. These plastic-coated fabrics are non-toxic, odorless, tasteless, and are FDA compliant (21 CFR 177.). They are dimensionally stabile from -100°F to +500°F (-73°C to 288°C), and provide exceptional durability and extremely low elongation (<1%).

Polytetrafluoroethylene (PTFE ) is a fluoropolymer that has a large number of industrial applications due to its many properties. One brand name for PTFE is Teflon®, which is known for its non-stick and heat resistant properties.
The properties that make PTFE or polytetrafluoroethylene so useful include

low friction

inert

Self-cleaning

Durable

Effective over a wide range of temperatures

Non-flammable

Corrosion resistant

High resistance

Its properties mean that what we often call the non-stick coating of cookware is particularly important for its inertness and heat resistance.



PTFE was discovered by accident in by a DuPont engineer working in refrigeration. That happy accident led to the birth of an industry.

PTFE-coated fibreglass fabrics or PTFE sheets, made from PTFE (polytetrafluoroethylene) coated glass fibres are mainly used in packaging and sealing devices to prevent foils from sticking to strips and sealing jaws.


In addition, PTFE-coated fibreglass fabric is used as a sliding material while moving products horizontally on tables, production lines, etc. In vertical packaging machines, PTFE-coated fibreglass fabrics are used to adhere to tubes where products are dropped. PTFE-coated fibreglass fabrics are also used as a sliding material in internal transport machines, pallets and product receivers, and conveyor belts.

Polytetrafluoroethylene or PTFE (polytetrafluoroethylene) is commonly known by its parameters, including high temperature resistance, as an insulating material for sealing jaws in sealing machines.

Fibreglass fibre fabrics with a low PTFE content are called PTFE-coated fibreglass porous fabrics. They are used to obtain so-called textures in welding, or embossed woven glass fibre foils. The PTFE content of about 30% of PTFE-coated glass fibre porous is sufficient to use them as anti-stick protection and to provide a nice seam-textured grille.

Uses of PTFE fibreglass cloth.

As insulation for heating elements, e.g. sealing strips in sealing machines

as consumables in sealing machines, packaging machines and conveyors

As a lubricant to prevent adhesion to sticky surfaces

In activities where anti-adhesion is required or where non-adhesive surfaces are used

PTFE Coated Fiberglass Fabric

The most important advantages of PTFE-coated glass fibres include

Prevention of adhesion - PTFE has a low coefficient of friction

Easy to keep the material clean

Dielectric properties

Heat resistance up to +250°C

Flexibility allows it to be used on uneven surfaces

Lack of expansion or contraction during temperature changes

Chemical resistance

Resistance to adverse weather conditions

Resistance to mechanical damage

Resistance to moisture

Among our products you will find PTFE fibreglass fabrics for automatic sealing machines, manual and vacuum packaging machines and other packaging machines. PTFE fibreglass fabrics are an excellent material for insulating the sealing strips of plastic bags during the welding process. In this way they prevent the foil from sticking to the sealing strip and improve the sealing quality and strength of the packaging.

PTFE sheets and PTFE fibreglass fabrics are made of glass fibres coated with PTFE - polytetrafluoroethylene. PTFE is particularly well known for its very good resistance to high temperatures.

PTFE fiberglass fabric is available to variety of sizes, on rolls, or manufactured to your customized requirements.
