Sealer Sales FR-770II Horizontal/Vertical Continuous Band Sealer with Conversion Kit, 10mm Seal, Left-to-Right Feed, Embossing

The Sealer Sales FR-770II is a stainless steel continuous band sealer, the dual-mode version that ships horizontal and includes the vertical conversion kit. The FR-770 is one of the most popular band sealers in its class because it handles 20 to 26 six-inch wide poly bags per minute, accepts almost any thermoplastic film (PE, PP, laminated foils), and feeds left to right (the mirror configuration of the right-feed CBS-880 family). Stainless construction and a long spare-parts pipeline make it a workhorse you can keep in service for years.

Left-to-Right Feed

The FR-770II is the left-feed version of the FR-770 chassis. The operator stands at the left side of the conveyor and bags exit to the right. This is the mirror configuration of the right-feed CBS-880 family. Match feed direction to your production line layout so the operator does not have to reach across the conveyor.

10 mm Seal Width with Solid-State Temperature Control

A 10 mm seal is wide enough to give a hermetic, peel-resistant bond on most poly films. The FR-770II keeps the seal bars at their target temperature with a solid-state temperature controller, so the first bag of the run looks identical to the last bag. Temperature drift is what causes intermittent leakers, and a solid-state controller is what stops it.

Built for Daily Production

Frame is stainless steel for washdown environments. The conveyor is motorized rubber with variable speed control. Knurled pressure wheels adjust to compensate for film thickness so a 4 mil bag closes with the same dwell as a 2 mil bag. One pair each of cooling and heating blocks means the bag is fully cooled before it exits the conveyor, so you do not pull a hot, still-relaxing seal that distorts on the way out. An emergency stop is wired into the front panel.

Spare Parts and Field Service

The FR-770 family has been in production long enough that the spare parts kit is well stocked: PTFE sealing belt, drive belt, PC board, tools, and the standard typeset (numbers 0-9 plus letters EXD). Most operators keep one belt and one drive belt in a drawer next to the sealer.

Ships Horizontal, Converts to Vertical with the Included Kit

The FR-770II ships in horizontal configuration but includes the conversion kit to switch to vertical. In vertical mode the conveyor stands the bag upright and is sized for filled-bag heights of Min 7.8" / Max 12.0". Vertical mode is what you want for sealing bags of powder, granular product, or anything else that will not stay flat on a horizontal conveyor.

Embossing on the Seal Line

The FR-770II includes an embossing wheel that stamps your text directly onto the seal line without ink. Standard character size is 3 x 4 x 9 mm and the optional embossing layout is one line in three sections, fifteen characters per section. The wheel can be swapped for a smooth seal if you prefer no marking, or a serrated seal for grip. None of this requires ribbons, ink, or wet supplies. Embossing is purely mechanical.

Configurable for Your Line

For facilities that need more than the standard configuration, the FR-770II can be ordered with an alternate 15 mm seal width, a smooth or serrated seal wheel in place of the embossing wheel, an integrated digital counter to track sealed bag count, a stainless steel floor stand (horizontal units only), an extended vertical height kit raising filled bag range to 12-16 inches (vertical units only). These options are factory-fitted when you place the order.
