PTFE fiberglass fabric, teflon tapes, and teflon belts play a crucial role in the packaging industry. Whether for heat sealing, heat shrinking, or side sealing, our products are essential in the final stages of the production cycle, offering temperature resistance, dimensional stability, and easy-to-clean, smooth surfaces to facilitate successful operations. We offer a variety of textured or smooth, porous or non-porous, and tear-resistant products to meet your company’s demanding production needs.
Heat Sealing
With its exceptional non-stick properties, PTFE fiberglass fabric and ptfe adhesive tapes effectively prevent film adhesion, ensuring smooth and clean seals without stringing. Their superior heat resistance (up to $260^{\circ}C$) and low friction coefficient significantly boost the efficiency of high-speed automatic sealing and cutting machines while reducing equipment wear. Furthermore, their excellent electrical insulation and chemical stability extend the lifespan of blades and consumables, making them essential materials in the packaging industry for minimizing downtime maintenance costs and enhancing sealing quality.
Heat Shrink Packaging
In the shrink tunnel of heat shrink packaging, open-mesh polytetrafluoroethylene (PTFE) conveyor belts primarily serve the dual role of load-bearing and efficient heat transfer. The open mesh design (typically 4x4mm or 10x10mm) ensures high-speed circulation of hot air within the shrink chamber. The PTFE coating provides the belt with excellent release force. Even at temperatures up to 260°C, shrink film residue or hot melt adhesive will not adhere to the belt. The conveyor belt does not stretch or deviate under long-term high-temperature tension, significantly reducing equipment maintenance frequency and costs.
Side Sealing
Used to wrap napkins, paper towels, tissue, and toilet paper in plastic, paper products are grouped together, covered in a thin plastic, and then.
On production lines for household paper products such as tissues and toilet paper, after the product is covered with PE or POF film, it needs to pass through a high-temperature “shrinkage tunnel.” At this stage, (Teflon) PTFE conveyor belts play a crucial role.
If you are looking for a more durable solution, you can generally consider PTFE belts with Kevlar as the base material, as their tensile strength and folding resistance are better than ordinary fiberglass base materials.
Extrusion Coating & Lamination
In the extrusion coating and lamination of milk cartons, snack packaging, and photo paper, PTFE fiberglass fabrics and oriented films provide critical advantages:
Ultimate Non-Stick Release: They prevent molten resins (PE/PP) from sticking to the pressure rollers, ensuring a flawless surface finish and high gloss for photo paper.
High Temperature & Dimensional Stability: They withstand continuous heat up to 260°C and high pressure without deformation, maintaining precise coating thickness and uniformity.
Chemical Inertness: They are safe for food-contact packaging, ensuring no contamination or migration of substances.
Operational Efficiency: Their high tear strength and easy-to-install adhesive backings reduce downtime, minimize waste, and enable high-speed, continuous production.
High-quality PTFE fiberglass cloth utilizes a deep impregnation process, ensuring that the PTFE resin not only coats the surface but also penetrates into every warp and weft thread of the fiberglass.
We use high-modulus E-glass, which has an extremely low coefficient of thermal expansion. Even under continuous high temperatures of 260°C, the fabric maintains excellent dimensional stability in both the transverse and longitudinal directions (shrinkage < 0.5%). This tight molecular bond ensures that the surface remains smooth and mirror-like after thousands of heat-sealing cycles, without coating peeling or carbonization. For you, this means longer replacement cycles and a near-zero sealing defect rate.
"Safety and compliance are the bottom line for our products. Our PTFE heat-sealing materials are manufactured using a strictly **PFOA-Free** process, fully complying with FDA 21 CFR 177.1550 and European LFGB food contact standards.
All our production batches undergo migration testing by third-party testing agencies (such as SGS or Intertek) to ensure that no harmful chemicals migrate to the packaging surface during the high-temperature heat-sealing process. This not only provides you with a 'passport' to the European and American markets, but also serves as a brand endorsement for the health of your end consumers. We can provide a complete Declaration of Compliance (DoC) to support you in meeting the most stringent supply chain audits."
We employ precision overlap welding or bullnose joint technology to ensure the joint thickness is almost identical to the belt body, eliminating sealing defects caused by pressure fluctuations. Combined with Kevlar thread stitching reinforcement, the joint tensile strength is increased by 30%. This means that even under high-speed, high-temperature, and high-load conditions, the belt can maintain smooth operation, significantly extending its service life and reducing your unplanned downtime.
Our PTFE coating is completely PFOA-free, complies with FDA 21 CFR 177.1550 standards, and provides a complete Certificate of Compliance (DoC). At the same time, this coating has extremely high chemical inertness, resisting various strong cleaners with pH values between 0-14. This not only ensures absolute safety for food contact but also guarantees that the belt surface will not crack or peel off due to chemical corrosion under rigorous hygiene audits.
The high cost isn't the tape itself, but the downtime. Our product uses a high-content premium PTFE resin and a high-density electronic-grade fiberglass base, offering over 30% better abrasion resistance than conventional products on the market.
It maintains extremely strong adhesion even under sustained high temperatures, without edge lifting, and leaves absolutely no glue residue upon replacement. This means your technicians don't need to stop to clean the cutter, significantly increasing equipment uptime. By extending its lifespan by 1.5 times, we can directly reduce your annual overall consumable costs by 20%-25%.
Our PTFE consumables use a completely PFOA-free coating process and have passed dual certification by the FDA (U.S. Food and Drug Administration) and LFGB (German Food Hygiene Standard). Furthermore, for the EU market, the product complies with REACH and RoHS environmental regulations. We provide test reports from third-party laboratories (such as SGS or Intertek) proving that the material maintains extremely high chemical inertness at continuous high temperatures of 260°C, with absolutely no migration of toxic substances, ensuring that your packaging process fully complies with international food safety traceability systems.
