VFFS timing belts utilizing Neoprene or Polyurethane base belts with a hardness of 90 ShA, available in both metric and inch profiles.
vFFS Belts are potential replacement belts for Vertical Form Fill and Seal Machines such as AppecAstro, Bosch, Eagle, Fabrima, Fres-co, Fuji, Kopas, Matrix, GIC, Hassia Redatron, Hayssen, Ilapak, Iman Pack, Ishida, Kawashima, Kliklok-Woodman, Gainsborough, Mesoma, Rovema, Sandiacre, Sellier & Bellot, Simionatio, Stiavelli, TNA, Triangle and Volpak.
These VFFS Draw Down Belts are composed of three layers: an endless basic toothed timing belt, adhesive, and a seamless coating with a hardness ranging from 40-55 ShA. We offer various coating options including silicone, rubber, PU and Linatex.
Vacuum Timing Belts usually have profiles of T10, 5M, 8M, S8M, XL, L and H, while custom sizes (lengths, widths and pitches) are available upon request.
Our vacuumed VFFS timing belts come with a variety of shapes and hole patterns, and our fabrication services include slotting, grinding, grooving and tooth removal.
For customers requiring Suction Belts made from FDA quality materials, we offer VFFS timing belts with a polyurethane base and silicone cover.

We offer five types of belt punching options for the conventional vacuum film stretchers. These are some of the cases we have handled. Of course, we have also dealt with other types. You can contact our sales customer service team to obtain more information.
Film Feeding & Positioning: Ensures accurate pulling of plastic film for pouch formation.
Synchronization with Filling Mechanism: Coordinates product filling with bag formation for high-speed operation.
Sealing & Cutting Alignment: Keeps film in perfect position for consistent heat sealing and cutting.
Our customer service representatives and engineering team work together to provide solutions to your belting needs with unsurpassed quality.
With a vacuum timing belt, products and packages can be fixed to the timing belt by vacuum. This is done by grinding a vacuum chamber into the timing belt. In this way, for example, lightweight products and packaging materials can be conveyed vertically and at high speeds with precision.
Truly Endless and Spliced Coatings: Natural Rubber, Polyurethane ( PU ), Neoprene, Nitrile, Gum Rubber, NBR, XNBR, Sponge Rubber, Foam – PU and Neoprene, Silicone, Teflon, PVC, EPDM, Felt as well as numerous FDA quality options
Fabrication: Includes perforation of holes – standard, countersunk, multi-depth in varying sizes and shapes, tooth removal – groove, slots, profiling, grinding, punching
Yonghang supplies an extensive range of standard and custom made timing vacuum belts.
Our industrial belts are suitable for most popular machines on the market. We are also able to produce custom made belts, bands and other accessories and are happy to provide customised services to assist with special requirements. We are able to meet specific requests whether through the use of different base and coating materials and / or altering profiles, finishes and adjusting vacuum holes, slots and grooves to increase or decrease suction surface area.
The majority of our fabricated belts are molded seamless truly endless (without a joint). Application of the truly endless belts in the production process greatly reduces many problems associated with spliced belts such as: uneven wear, breaks on the joint line, variation in the speed and movement of the belts. Elimination of spliced joints means that an even hardness is achieved resulting in an increased reliability, durability and longevity. A greater reduction in breakdowns and consequent down time are the major benefits of using our seamless belts.
Our range includes spliced belts – these are supplied if this option is preferred by our customer or if required due to specific application or the size of the belt.
Whatever your belting requirements might be, we are here to help you.
The following is not an exhaustive list of our products.

Yes，Yonghang has been manufacturing VffS timing belts in China for 20 years.
The maximum operating temperature of the silicone coating is 220°C.recommend silicone material, which lasts three times longer than standard products and give better grill.
PU, PE and Fluororubber,For specific application scenarios, you can contact our expert team. We will recommend the most suitable materials for you.
Endless made from a vulcanized sleeve with no joints MOQ 1 sleeve，For specific application or belt size requirements, we can provide these spliced belts with MOQ 1 pc.
The VFFS belt does not have a fixed service life, as it is influenced by multiple factors:
Influencing factors include: the belt’s inherent quality, the equipment’s daily operating hours, load size, working environment (temperature, presence of corrosive substances), and most importantly—whether installation and maintenance are performed correctly.
VFFS belts with blind holes are perforated coated timing belts designed to create suction, or “vacuum,” which holds and transports products firmly on their surface. The blind holes allow for air to be drawn through them, creating the vacuum effect without the need for a filter, making them ideal for conveying lightweight, flexible, or difficult-to-grip items like film or lightweight products in Film packaging machine，Powder vertical packaging machine，Potato chip vertical packaging machine
non-perforated VFFS belts is coated timing belt,Relying on surface coatings to increase friction, it lacks vacuum adsorption capabilities and is also used in vertical packaging machines.
