Clear Plastic Face Shield/Sneeze Guard Guide

Due to the current pandemic clear performance plastics are in high demand for use in the production of clear plastic face shields or Sneeze Guards. In the beginning these face shields were being produced for nurses and doctors on the front line, to provide any extra layer of protection over their face mask. In concept, these face shields are worn to prevent individuals from touching their face and provide a moisture resistant barrier from airborne particles. In response to the unforeseen future many more industries could be implementing these face shields as a uniform requirement. For instance, dentistry, food packaging, food service, mail carriers, child care centers, or any job or service that requires point of purchase situations or jobs that cannot be done at a social distance. Contact sports like football or lacrosse could also be soon implementing these protective face shields. Below is a guide for material tips and technologies used to manufacture clear plastic face shields and sneeze guards.

What materials is used to make face shield straps?

Many different companies and individuals have created their own face shield designs, utilizing different plastics and fabrics/fibers to construct their face shield headbands. Some designs have incorporated silicone foam to be utilized as a spacer that provides comfort and a space gap to create ventilation and prevent fogging. For strapping systems, some designs have incorporated stretchable elastic, similar to the kind used in your favorite pair of sweatpants. Other strap designs incorporate 3D Printed plastic frames or specialty die cut rigid plastics. More cost-effective designs do not use a strapping system and instead utilize special cut outs in the clear plastic shields enabling them to be attached to either normal eyewear (glasses) or headwear (hats).

CS Hyde recommend’ s using Velcro® One-Wrap® straps. Velcro® is conformable, extremely durable, and reusable. Utilizing Velcro®’s hook and loop technology the straps can be placed on each side of the shield and fastened by stitching or a type of riveting system. A faster process would be to create a slit in each side of the shield and run the Velcro® through each of the holes, making sure hook surface is on the outside. This process would create a buckle around the rectangular piece of plastic where the slit was created, the excess hook straps could be tightened around your head and then fastened down onto the loop surface. For example, imagine the Velcro® strap shoes we had to wear before we knew how to tie our shoes. Incorporating Velcro® One-Wrap creates the same concept, securable and fully adjustable straps for your face shield design.

What clear plastics are used to produce face shields/Sneeze Guards?

Choosing the right plastic for face shields depends on cost, durability, and processability. For these type of face shields clarity and transparency is a critical property requirement when identifying the right plastic. Most commonly face shields are produced from clear thermoplastic films including Polyester (PET), Polycarbonate (PC), or (PETG) in a thickness range from .007” to 030” or 7 mil. to 30 mil. (thousands of an inch). Each of these films have exceptional clarity, with only a couple factors setting them apart. Polyester is most chemical resistant, Polycarbonate is more abrasion resistant, and PETG is most cost effective. All these plastics have moisture resistance properties and can perform extremely well, so choosing the right plastic would depend on property specifics and budget costs related to your application.

How are clear plastic face shields cut?

In terms of processability or fabrication Polyester (PET), Polycarbonate (PC), or (PETG) can be easily cut with a utility knife. CS Hyde does not recommend laser cutting these plastic films because of their low melting point and possibly of discolored edging and smoke fume generation requiring an extra step sanitation procedure. Other cutting methods include rotary die cutting and overhead die cutting. These methods require a custom tool or mold to be made according to dimensions. Although rotary die cutting and overhead press die cutting can be a precise, fast method for production, there may be longer lead times and extra cost associated with manufactures who do not have in house tooling capabilities.

CS Hyde recommends digital knife cutting for mass producing face shields cut from clear plastic films. This type of cutting does not require special tooling and only requires a .DXF drawing (CAD data file format). This process utilizes an automated pneumatic knife/punch driven system that will cut the face shields according to specs replicated from the .dxf drawing. Digital Knife cutting creates smooth radius edges and precise punched holes. Minimal waste is also a benefit, due to the machines automatic nesting program. The nesting software enables the machine to maximize material usage by minimizing the outer matrix. Digital knife cutting is a cost-effective cutting method that produces quality finished products in short turnaround times. CS Hyde provides digital knife cutting in house at our Midwest Illinois facility.

PTFE Fluoropolymers improve packaging equipment & applications

In the packaging industry many applications rely on materials that withstand extreme temperatures, resist friction and include release properties. Fiberglass tapes and fabrics coated with Teflon™ PTFE can be an ideal solution to incorporate these benefits into packaging applications. These products can be applied on heat sealing equipment including commercial bag sealers, L-Bar sealers, or impulse wire sealers as element covers. Fiberglass tapes can also be used to improve molding applications and fill/form/seal blister packaging.

PTFE Coated Fiberglass TapesPTFE (Teflon™) coated fiberglass Tape

The most common tape used for these types of applications is PTFE (Teflon™) coated fiberglass, a woven fiberglass fabric.  This tape can be supplied with silicone or acrylic adhesive. Generally, most applications need silicone adhesive due to its temperature resistance of up to 500°F and its clean release properties for replacement installation. Acrylic adhesive is used for high tack adhesion for stronger hold and has a temperature resistance of -40°F to 375°F. CS Hyde Company offers two different versions of PTFE (Teflon™) coated fiberglass: standard-grade and ultra-premium grade.

Standard Grade: General Purpose Grade

  • Available with or without liner.
  • Thicknesses: 3 mil., 5 mil, 6 mil., 10 mil., 14 mil.

Ultra-premium Grade: Improved base fiberglass and extra coating of Teflon® PTFE

  • Available in thicknesses: 3 mil., 5 mil., 10 mil.

Custom slit widths available.  No minimum order quantities.

PTFE (Teflon™) coated fiberglass Fabric

If an application does not require adhesive, PTFE (Teflon™) coated fiberglass fabric is an ideal alternative. Fabric is commonly used in plastic packaging as a release sheet on welding plates. We offer five different versions: standard grade, ultra-premium grade, mechanical grade, tear & crease resistant and semi porous.

  • Standard Grade: General purpose (Teflon™) coated fiberglass
  • Ultra-premium Grade: Higher base fiberglass and extra PTFE coating
